In 1919, the national Hydrographers of Great Britain and France cooperated in taking the necessary steps to convene an international conference of Hydrographers. London was selected as the most suitable place for this conference, and on 24 July 1919, the First International Conference opened, attended by the Hydrographers of 24 nations. The object of the conference was "To consider the advisability of all maritime nations adopting similar methods in preparation, construction, and production of their charts and all hydrographic publications; of rendering the results in the most convenient form to enable them to be readily used; of instituting a prompt system of mutual exchange of hydrographic information between all countries; and of providing an opportunity to consultations and discussions to be carried out on hydrographic subjects generally by the hydrographic experts of the world." This is still the major purpose of the IHO.

In 2013, INS Jamuna conducted a hydrographic survey off the Kenya coastline on the request of the Kenyan government to survey Manda Bay and Kiwaiyu Bay. Subsequently, the "first updated navigational charts" of the areas were presented to Kenyan authorities in 2014 by the Chief of the Naval Staff, Admiral RK Dhowan. The ship also conducted a hydrographic survey off the Dar es Salaam port in Tanzania.

A nostalgic 1985 sketch of hydrographic surveying in Alaska. Neptune, a privately owned survey ship based in Chicago, Illinois. Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities.

Cormorán was built in the Río Santiago Shipyard. Commissioned by the Argentine Navy in February 1964, she was assigned to the Naval Hydrographic Service ( Servicio de Hidrografía Naval). Since then she has undertaken several campaigns, which included depth sounding, current measuring, water sampling and bottom sampling. In 2010 she supported the hydrographic surveys performed in the Río de la Plata by the Uruguayan ship ROU Sirius.

In 1928 he passed his exams and received an external degree from the Odessa Navigation College and was qualitfied as a navigator. In 1930 Georgy finished the special courses of the commanding staff of the Red Navy at the oldest college in Russia – the Frunze Naval College (hydrographic class). He became the commander of HS (hydrographic ship) "Tsyrkul" at the Yenisei pilot distance of the Ubekosibir.

These vessels usually mount equipment on a towed structure, for example, air cannons used to generate shock waves that sound strata beneath the seabed, or mounted on the keel, for example, a depth sounder. In practice, hydrographic survey vessels are often equipped to perform multiple roles. Some function also as oceanographic research ships. Naval hydrographic survey vessels often do naval research, for example, on submarine detection.

The Pakistan Navy Hydrographic Department (Reporting name: PN Hydrographic Department), is an active-duty and non-combatant naval administrative staff command, and one of the major science and technology command of the Pakistan Navy. The command served as the operational scientific naval oceanographic program for the Government of Pakistan and jointly conducts research and development programs with civilian National Institute of Oceanography. Commissioned in 1959, the command is headquartered with the Naval Headquarters (NHQ) in Karachi, Sindh, and directly reported to Naval Surface Fleet (NFS). The command is mandate to conduct studies on hydrographic surveys of coastal and offshore waters of Pakistan, and publishing nautical charts and relevant publications.

On March 10, 2015, the Hydrographic Center of the Brazilian Navy began issuing warnings on Subtropical Depression 3 during early afternoon, while the Center for Weather Forecast and Climatic Studies (CPTEC in Portuguese) already assigned the name Cari for the storm. At 00:00 UTC on March 11, the Hydrographic Center of the Brazilian Navy upgraded Cari to a subtropical storm, also assigning a name to it. On March 12, the Brazilian Hydrographic Center downgraded Cari to a subtropical depression, while the CPTEC stated that the storm had become a "Hybrid cyclone". During early afternoon of March 13, the Brazilian Navy declared that Cari became a remnant low.

The International Hydrographic Organization's delineation of the "Southern Ocean" has moved steadily southwards since the original 1928 edition of its Limits of Oceans and Seas. Borders and names for oceans and seas were internationally agreed when the International Hydrographic Bureau, the precursor to the IHO, convened the First International Conference on 24 July 1919. The IHO then published these in its Limits of Oceans and Seas, the first edition being 1928. Since the first edition, the limits of the Southern Ocean have moved progressively southwards; since 1953, it has been omitted from the official publication and left to local hydrographic offices to determine their own limits.

A Helical Hyperspatial Code, also known as an HHCode, is a data storage format for very large spatio-temporal datasets. The development of HHCode can be traced to efforts by scientists working for the Canadian Hydrographic Service's Atlantic regional offices at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia. CHS was facing a problem with storing very large spatial datasets acquired during hydrographic surveys (thus having a temporal element) and was seeking a method to store the datasets in a relational database structure. CHS scientists reportedly conceptualized a spatio-temporal indexing system during a hydrographic survey onboard CCGS Hudson on Georges Bank during the summer of 1989.

The International Hydrographic Organization defines the northern limit of the White Sea as "A line joining Svyatoy Nos (Murmansk Coast, 39°47'E) and Cape Kanin".

She operated from there for the next five months, performing hydrographic work; sometimes as far afield as Okinawa. Simon Newcomb returned to the west coast on 25 December 1945 and was routed to Norfolk, Virginia, via the Panama Canal, arriving on 21 January 1946. From early February to 2 May, the survey ship operated with a hydrographic party off the Bahama Islands. On 29 July, she was redesignated as AGSC-14.

Ecorregión Mar Argentino The current is an equatorward flowing current that carries cold and relatively fresh subantarctic water. The Falkland Current is a branch of the Antarctic Circumpolar Current. It transports between 60 and 90 Sverdrups of water with speeds ranging from a half a meter to a meter per second. Hydrographic data in this area is very scarce and thus various hydrographic variables have a great deal of error.

Old nautical chart by the Hydrographic Office, showing depths in fathoms Most modern nautical charts indicate depth in metres. However, the U.S. Hydrographic Office uses feet and fathoms. A nautical chart will always explicitly indicate the units of depth used. To measure the depth of shallow waters, boatmen used a sounding line containing fathom points, some marked and others in between, called deeps, unmarked but estimated by the user.

In 1863, he was named director of the Maritime School of Ancud (Escuela Maritima de Ancud). In 1874, he became the first director of the newly created Hydrographic Office (Oficina Hidrográfica). In 1884, he became General Inspector of Lighthouses and participated in the International Meridian Conference. Because of his neutrality during the 1891 Chilean Civil War he was removed from his post as director of the Hydrographic Office.

The International Hydrographic Organization (IHO) is an intergovernmental organization representing hydrography. In October 2019 the IHO comprised 93 Member States. A principal aim of the IHO is to ensure that the world's seas, oceans and navigable waters are properly surveyed and charted. It does this through the setting of international standards, the co-ordination of the endeavours of the world's national hydrographic offices, and through its capacity building programme.

Forestry is the main economic activity of this hydrographic slope; recreational tourism activities, second. The surface of the river is usually frozen from mid-December to mid-April.

She included in her ports of call Scapa Flow in the Orkney Islands, Oslo, Norway, and Copenhagen, Denmark. Hydrographic survey ship USS San Pablo (AGS-30) ca. 1967.

While at about the same latitudes, Cook's real "Sandy I." was four degrees of longitude—hundreds of miles—further east than the 160° E that became the usual location of the fictitious Sandy Island on later charts and maps that were drafted after the development of the marine chronometer and accurate longitude reckoning. Hydrographic charts later placed the internationally recognized abbreviation "ED" ("existence doubtful") next to Sandy Island, in recognition of subsequent failures to spot the reported island at the expected location. Seafloor mapping in the area by the Australian Hydrographic Service (AHS) determined a minimum depth for the immediate area around and over the island ranging from below sea level. Due to a lack of appearance of an island or depths indicating a shallow reef, Sandy Island was removed from the official French hydrographic charts by the French Hydrographic Service in 1974 after a flying recognition campaign and by AHS in 1985.

In 1942–1945 he served in the Hydrographic Administration of the Navy. He served as director of Roshydromet (Russian equivalent of National Oceanic and Atmospheric Administration) 1947–1950.

Laptev Sea's limits as defined by the International Hydrographic Organization. This definition and bathymetry with 1 arc-minute resolution leads to an area of 502000 km2 which compares to 672000 km2 from WolframAlpha. The International Hydrographic Organization defines the limits of the Laptev Sea as follows: > On the West. The eastern limit of Kara Sea [Komsomolets Island from Cape > Molotov to South Eastern Cape; thence to Cape Vorochilov, Oktiabrskaya > Revolutziya Island to Cape Anuchin.

The term hydrography is used synonymously to describe maritime cartography, which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user. Hydrography is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters.

He was later Assistant Director of Naval Intelligence, with the rank of acting captain, and a naval delegate and French translator at the Versailles Peace Conference in 1919. After acting as secretary and official interpreter to the First International Hydrographic Conference, London, 1919 he was elected the first secretary-general of The International Hydrographic Bureau. He served in that role from 1921 to 1937. His later years were spent in British Columbia.

In December 1937 she was transferred to duty with the Hydrographic survey and carried out her operations on the coasts of Colombia, Venezuela, Trinidad, British Guiana, and Samoa until September 1941.

In Australia, the body of water south of the continent is officially gazetted as the Southern Ocean, whereas the International Hydrographic Organization (IHO) designates it as part of the Indian Ocean.

The oceanographic winch and large after A-frame work in conjunction to serve her stern sampling station, while the two hydrographic winches work with the side A-frame to service her side sampling station, and the two hydrographic winches together give Oscar Dyson the capability to have two scientific packages ready for sequential operations. In addition to trawling, her sampling stations can deploy smaller sampling nets, longlines, and fish traps. The hydrographic winches can deploy CTD instruments to measure the electrical conductivity, temperature, and chlorophyll fluorescence of sea water. Oscar Dyson also can deploy specialized gear such as Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) frames, towed vehicles, dredges, and bottom corers, and she can deploy and recover both floating and bottom-moored sensor arrays.

Despite this, survey activities were performed by Royal Navy vessels until World War I, when surveying operations were concentrated in European waters. After the war, the Admiralty decided that with higher priorities in Europe, it would provide at most a single vessel for survey operations around Australia, and the Australian government was forced to create its own hydrographic surveying service. After deliberation on whether the new hydrographic service would be military or civilian operated, the government decided that surveying would be a naval responsibility, with the RAN Hydrographic Service established on 1 October 1920. A single sloop, , was commissioned into RAN service to supplement the Royal Navy survey vessel, and was later fitted with a Fairey IIID seaplane to assist with surveys of the Great Barrier Reef.

Those included modifying the aircraft electrical systems, replacing parts with nonmagnetic materials and adding compensators. By spring of 1953 the system was proven to be able to collect vector geomagnetic data and began operations that included intensity, dip and variation data for Project Magnet. With proven success the Hydrographic office and the United States Coast and Geodetic Survey, which also had magnetic survey responsibility over U.S. territory, arranged for the approval of the member states of the International Hydrographic Organization (IHO) of the project with provision that magnetic variation charts be published at five year intervals (Epochs) by the Hydrographic Office. The introduction of the proton precession magnetometer enabled supplemental data collection from steel hulled ships making the extreme measures used for Carnegie unnecessary.

The establishment of two professional scientific organizations, the Hydrographic Survey of Canada and the Biological Board, the precursor of the Fisheries Research Board, at the turn of the 20th century, marked the beginning of modern Canadian oceanography. As the result of a tragic marine accident on Georgian Bay the Government of Canada created the Georgian Bay Survey in 1883 to produce reliable navigation charts for safe navigation on that Bay and Lake Huron. The Survey began the hydrographic charting of the west coast in 1891, tidal and current metering in 1893 and the charting of the St. Lawrence River below Quebec City, in 1905. In 1904 under an Order-in -Council it became the Hydrographic Survey of Canada with an expanded mandate.

The following autumn, Albatross resumed her scientific work, cruising from Norfolk to the Gulf of Mexico and Havana, Cuba, conducting hydrographic investigations of the Gulf Stream between 30 October and 15 December 1919. The following year, Albatross departed Baltimore on 16 February 1920 and proceeded to the waters off New England. She then operated out of Boston into the spring, carrying out hydrographic work in the Gulf of Maine. She returned to Baltimore on 30 May.

The Malvinas Current (also called Falkland Current or Falklands Current) is an equatorward flowing current that carries cold and relatively fresh subantarctic water. The Malvinas Current is a branch off of the Antarctic Circumpolar Current. It transports between 60 and 90 Sverdrups of water with speeds ranging from a half a meter to a meter per second. Hydrographic data in this area is very scarce and thus various hydrographic variables have a great deal of error.

After Indian independence in 1947, the department continued its functions under the Surveyor-in-Charge of the Marine Survey of India from Bombay. Later the office was shifted to Dehradun by renaming it as Naval Hydrographic Office headed by Chief Hydrographer of the Navy, which was later re-designated Chief Hydrographer to the Government of India in 1964. In view of international role of India in hydrography, the office was renamed once again in 1997 as National Hydrographic Office.

The Ginger Islands are a group of islands lying west of Cape Alexandra, off the southern end of Adelaide Island, Antarctica. The largest of the islands appears reddish when free of snow. They were surveyed by the Royal Navy's hydrographic survey unit in 1962-63 and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Kenneth Ginger, Civil Hydrographic Officer responsible for British Admiralty charts of the Antarctic for several years beginning in 1958.

The expedition's ship Nimrod departing for the South Pole During Rear-Admiral A Mostyn Field's term as Hydrographer to the Admiralty Board, the Hydrographic Office lent instruments to the Nimrod Expedition of the British Antarctic Expedition led by Ernest Shackleton in 1907. Following the RMS Titanic in 1912, the Safety of Life at Sea (SOLAS) convention was established, as well as the introduction of ice reporting and forecasting. During World War I, while Rear-Admiral Sir John F Parry was Hydrographer of the Navy, the Hydrographic Office produced numerous new charts and products to support the Royal Navy. Following the war, the First International Hydrographic Conference was held in London. It led to the establishment in 1921 of the International Hydrographic Organization. In the 1930s, the systematic and regular collection of oceanographic and naval meteorological data started. In the Second World War, while led by Vice-Admiral Sir John A Edgell, chart printing moved to Creechbarrow House in Taunton in June 1941. This was the first purpose-built chart making factory, and was designed by the Chief Draughtsman, Mr Jowsey.

Promoted to midshipman 1839, lieutenant 1845. In 1843–1844, he participated in hydrographic works in the Gulf of Finland on board the schooner Meteor. In 1846–1847, he served at the Black Sea.

The Institute ceased to exercise its monitoring and record-keeping functions in 1908, when the task, along with records and instruments, was passed to the Hydrographic Office of Venice. After the unprecedented acqua alta of 1966, the city set up a dedicated service to analyse data, monitor fluctuations, and forecast high tides, which is also charged with continuously keeping the population informed. Renamed Tide Monitoring and Forecast Center in 1980, the service has absorbed the record-keeping functions of the Hydrographic Office.

S-63 is an International Hydrographic Organization (IHO) standard for encrypting, securing and compressing electronic navigational chart (ENC) data. The Data Protection Scheme was prepared by the IHO Data Protection Scheme Advisory Group, and was based on the protection scheme developed and operated by Primar as part of providing their protected ENC service. ECC (Electronic Chart Centre) and United Kingdom Hydrographic Office were the original contributing organizations. The UKHO has since left this arrangement and Primar is now operated exclusively by ECC.

Møller Bank () is a submerged bank, with least depth of , at the northern end of Kista Strait, west of Welch Island, and just east of Carstens Shoal, in Holme Bay, Mac. Robertson Land, Antarctica. It was charted in February 1961 by d'A.T. Gale, a hydrographic surveyor with the Australian National Antarctic Research Expeditions (Thala Dan), and was named by the Antarctic Names Committee of Australia for J. Wennerberg Møller, third mate on the Thala Dan in 1961, who assisted in the hydrographic survey.

Allegheny was recommissioned on 25 July 1949 and departed for the Norfolk Naval Shipyard arriving on 8 August and remaining until 26 September when she sailed for New York. The ship departed New York on 1 October 1949 for the Mediterranean in company with and the survey ship which composed Hydrographic Survey Group One of the U.S. Navy Hydrographic Office. The group reached Gibraltar on 13 October. Transiting the Mediterranean the survey group put in at Naples, Italy on 19 October.

The two nearly identically sized ships present a contrast in shipbuilding eras and offer an ironic comparison as Sackville is a warship which became a part-time hydrographic ship and Acadia is a hydrographic ship which became a part-time warship. Acadia is the only known vessel still afloat to have survived the Halifax Explosion in 1917. Every year on the December 6 anniversary of the explosion, Acadia hoists exactly the same signal flags she flew on the day of the explosion.

Havengore entered service with the PLA on 4 February 1956. As the PLA's hydrographic survey vessel, she was responsible for recording changes to the bed of the River Thames and Thames Estuary. She was the first survey vessel in the UK to install a computer to record survey data, using punched tape; replacement Unix workstations were installed in 1989. After becoming the longest-serving PLA vessel, she performed her last hydrographic work in 1995, when she was withdrawn from service and sold.

In August 2007 he warned that the government's failure to carry out any hydrographic survey since 1933 had pushed up the cost of cargo freight. Without current charts, foreign vessels see Nigeria's territorial waters as dangerous, and therefore increase their freight charges to cover the risk. He called for government funding for a new survey. He said that Nigeria lost out at the recent elections of officers of the International Hydrographic Organisation because there was hardly any hydrography practice in the country.

After the Civil War, Wyman commanded , the flagship for the European Squadron. He was promoted to captain on July 25, 1866, and took command of the steam sloop the following year. After that tour of sea duty, Wyman headed the Navy's Hydrographic Office for eight years, receiving promotions to commodore on July 19, 1872, and to Rear Admiral on April 26, 1878. His leadership of the Hydrographic Office proved to be of great importance to the Navy and seafaring men in general.

The latter are best representations of the actual seabed, as in a topographic map, for scientific and other purposes. Trends in hydrographic practice since c. 2003–2005 have led to a narrowing of this difference, with many more hydrographic offices maintaining "best observed" databases, and then making navigationally "safe" products as required. This has been coupled with a preference for multi-use surveys, so that the same data collected for nautical charting purposes can also be used for bathymetric portrayal.

Dalrymple was succeeded on his death in 1808 by Captain Thomas Hurd, under whose stewardship the department was given permission to sell charts to the public in 1821. In 1819 Captain Hurd entered into a bi-lateral agreement with Denmark to exchange charts and publications covering areas of mutual interest. This is thought to be the earliest formal arrangement for the mutual supply of information between the British and any foreign Hydrographic Office. Hurd developed the specialism of Royal Navy hydrographic surveyors.

He next reported to Washington, D.C., for duty in the Navy Department's Hydrographic Office. During this tour, he helped complete a new set of precomputed tables to assist aviators and navigators in calculating their positions. Published in 1936, the new Aerial and Marine Navigation Tables were a vast improvement over the previous Ageton tables in terms of ease of calculation and accuracy, and were used for years afterward. He served as head of the Hydrographic Office's research division until 1937.

The Australasian Hydrographic Society (AHS) is a professional hydrographic organisation covering Australasia, the South West Pacific and South East Asia. It brings together practitioners and representatives of industry in the region, particularly those involved in maritime and port services, undersea exploration, offshore oil and gas projects and associated infrastructure. Because these sectors are closely linked to rapid growth in economic development and trade in the region, it is expected hydrography will have an increasingly important role in the future development of the economy.

From 1904 it was based in Buenos Aires, mostly in support and hydrographic survey duties. In 1918 was officially classified as hydrographic survey ship; it run aground in 1919 and 1920 suffering minor damage. In 1922 Azopardo was reclassified as tugboat, based at the port of Buenos Aires. On 5 August 1922 it was sunk as a result of a collision with the Mundson Line 22.000 ton steamship American Legion; in compensation Argentina received the transport ship América and the new tugboat Azopardo.

The IHO develops hydrographic and nautical charting standards. These standards are subsequently adopted and used by its currently 91 (as at August 2019) member countries and others in their surveys, nautical charts, and publications. The almost universal use of the IHO standards means that the products and services provided by the world's national hydrographic and oceanographic offices are consistent and recognisable by all seafarers and for other users. Much has been done in the field of standardisation since the IHO was founded.

The LADS Flight was a joint operation between the Australian Hydrographic Service and the Fugro LADS Corporation, part of Fugro a Dutch corporation, which also runs hydrographic operations for the private sector. The aircraft itself was owned by the Fugro LADS Corporation, which also provides the flight crews and system maintenance technicians. Aircraft engineers came from the civilian contractor, Cobham Aviation Services Australia, while the hydrographic specialists are serving members of the RAN. The flight was stationed at Cairns in the far north of Queensland, but could be deployed to other locations for up to three months at a time; the aircraft had an operational endurance of up to seven hours for operations close to its base, reducing to four hours on station at a distance of up to 300 nautical miles.

The UK Hydrographic Office is another data holder in the UK who has been listed by Free Our Data as a government office which is charging for the use of its data that Free Our Data believes should be opened for public use. The UK Hydrographic Office has data on tidal patterns and the position of astronomical bodies used in navigation, as well as being the primary holder of data for nautical charts, not just in the UK but also in many foreign locations, covering features such as bathymetry (depth), wrecks, underwater cables and pipelines, navigation buoys and lighthouses, and coastal features of interest to the mariner. Some of the hydrographic survey data is now being made available through the MEDIN portal as a result of the EU's INSPIRE initiative.

All four vessels are homeported at in Cairns, Queensland. They are used for hydrographic surveys of the shallow waters around northern Australia, primarily in the Great Barrier Reef. The vessels generally operate in pairs.

Hydrographic equipment includes variety of Differential Global Positioning System, Electronic Chart Display and Information System, Microwave Positioning systems, Dual Frequency Echo Sounders, Multibeam and Side Scan Sonars, Radio Tide Gauges, Profilers, Current Meters, CTD and Hydrographic data acquisition and processing software. Additionally there are Oceanographic and Geophysical research instruments. There are two Survey Boats equipped with DGPS and survey equipment to facilitate the surveying of shallow and inshore waters.

The Hydrographic Survey Bench Mark of 1878 at Bessie Point was listed on the Queensland Heritage Register on 9 May 2014 having satisfied the following criteria. The place is important in demonstrating the evolution or pattern of Queensland's history. The Hydrographic Survey Bench Mark at Bessie Point (1878) is important surviving evidence of the work of the Admiralty survey of Queensland's coastal waters, harbours and rivers, from 1862 to the 1920s. This survey was essential for safe shipping navigation and the economic development of Queensland.

He also ran an engineering consultancy on oceanographic instrumentation during part of the time. In 1950 he became a member of the German Hydrographic Office (DHI) in Hamburg (see Federal Maritime and Hydrographic Agency of Germany). He was responsible for regional oceanography and participated in several cruises on the survey and research vessels "Gauss" and "Anton Dohrn". He also became a lecturer in oceanography at Hamburg University in 1953 and adjunct professor in 1957 In 1959 he became the successor of Georg Wüst in Kiel.

The annual Taunton Carnival takes a route through the shopping district in the centre of the town. Taunton Deane had a low unemployment rate of 4.1 per cent compared with a national average of 5.0 per cent in 2005. Taunton is home to the United Kingdom Hydrographic Office (UKHO), an organisation of the Ministry of Defence responsible for providing navigational and other hydrographic information for national, civil and defence requirements. The UKHO is located on Admiralty Way and has a workforce of approximately 1100.

After the March 1921 trade contract between RSFSR, the United Kingdom, and Norway, the Kara Trade Expedition was organized under personal leadership of V. I. Lenin. After passing his exams, in summer of 1921 Georgy Rybin entered military service again in the Detached Hydrographic Party of the Ubekosibir (Siberian Department of Navigation Safety). He was a sounding steersman of the HS (hydrographic ship) №141. In 1922 Georgy left his studies and began his first officer's post as an interpreter of the 1st Ob pilot distance.

He started work for the Rideau Canal Office, Ottawa, and joined the one-year-old Georgian Bay Survey (later to become the Canadian Hydrographic Service) on March 22, 1884, at an annual salary of $550. He took over as Canada's First Chief Hydrographic Surveyor in 1893 and continued to survey in Georgian Bay and the North Channel until 1894. In 1891, he surveyed Burrard Inlet in British Columbia. In 1895-97, he with his ship Bayfield was in Lake St. Clair, Lake Erie and Lake Huron.

In 1951, Serrano was towed to San Diego where she remained until ordered activated and converted for hydrographic survey and oceanographic research work in 1960. With the designation AGS-24, she was recommissioned on 30 June 1960; and, 10 weeks later, she sailed for her homeport, Pearl Harbor. On 1 November, in company with , Serrano continued west to conduct a cable survey as far as Guam. From the Marianas, she proceeded via the Philippines into the Gulf of Siam for hydrographic and oceanographic operations.

Road R0806 (Penetration Road) cuts from east to west the lower Collin River; secondary and forest roads serve the entire hydrographic slope. The surface of the river is usually frozen from mid-December to mid-April.

Originally a fishing boat, she was refit with state- of-the-art instruments and equipment for hydrographic, geophysical, geotechnical, oceanographic and marine environmental surveys. The vessel is capable of conducting research work in depths up to .

Most of these were collected without incident. On November 28, 1940, the U.S. Navy's Hydrographic Office reported that the remains of the bridge were located at geographical coordinates , at a depth of 180 feet (55 meters).

In 1860, Lt. Bent was detailed to the Hydrographic Division of the Coast Survey, but resigned from the Navy on 25 April 1861 at the outbreak of the American Civil War, apparently because of Southern sympathies.

The Autonomous Community lies within three hydrographic regions, the Ebro River, the Tagus River (which originates in the Sierra de Albarracín range), and the Júcar, which has as its main river in this community the Turia.

Beaufort was certainly responsible for a step change in output; by the time he left the office in 1855, the Hydrographic Office had a catalogue of nearly 2,000 charts and was producing over 130,000 charts, of which about half were provided to the Royal Navy and half sold. In 1939, on the outbreak of World War II, the Hydrographic Office moved to Taunton, and the post of hydrographer moved with it. In 2001, a chief executive was appointed to run the United Kingdom Hydrographic Office as a profit-making agency of the British government, and at this time the roles of National Hydrographer and Hydrographer of the Navy were divided. The title of hydrographer devolved to Captain (hydrography and meteorology), a senior officer on the staff of the Commodore of the Devonport Flotilla, and the senior Royal Navy officer within the HM branch.

The INS Makar, a naval hydrographic vessel, had detected a large metallic object using its side-scan sonar at a depth of 50-60 metres. Later it was confirmed to be remains of the ill-fated aircraft.

Laid down on 11 June 1985 and launched on 15 November 1986, the hydrographic vessel Lapérouse entered into service on 20 April 1988. She was the first vessel of her class, and is currently serving with the Naval Hydrographic and Oceanographic Service of the French Navy (Service Hydrographique et Océanographique de la Marine-SHOM)). The ship was laid down on 11 June 1985 by DCN Lorient, launched on 15 November 1985, and commissioned by the French Navy as Lapérouse A791 on 20 April 1988. Lapérouse has her home port at Brest.

She performs hydrographic work for the Naval Hydrographic and Oceanographic Service (SHOM), although since 2 June 2000 she has been hierarchically attached to the Naval Action Force (FAN). Her main mission is scientific, but being a naval ship, she is also capable of handling piracy, terrorism, evacuating French citizens is case of natural or political crisis, or rescuing seamen in distressGironde : deux marins sauvés au large de Cordouan 1 October 2014 (French). Furthermore, she occasionally serves as a coast guard. The patron city of Lapérouse has been Albi (Tarn) since 7 October 1988.

Technically, the successor of the earlier Museum of Marine Sciences in Berlin today is the German Museum of Technology in Berlin. An important milestone in the IfM’s development was the commission of the new research vessel Meteor (Schiff, 1964), operated jointly by the German Hydrographic Office (see Federal Maritime and Hydrographic Agency of Germany) and the German Research Foundation (see Deutsche Forschungsgemeinschaft. The ship was used by all interested research groups in Germany. The first major expedition 1964/65 to the Red Sea and Indian Ocean was part of the International Indian Ocean Expedition.

The AHO is also responsible for the provision of operational surveying support and maritime Military Geographic Information (MGI) for Australian Defence Force (ADF) operations and exercises. The AHO has its origins in the British Admiralty Hydrographic Office, which was established in 1795. The Admiralty carried out surveys and published charts of the Australian coast throughout the 19th century in support of the defence and commercial development of the colonies. The Royal Australian Navy (RAN) assumed responsibility for hydrographic surveys in 1920, and for the publication of charts in 1942.

The island was discovered by Boris Vilkitsky during the Arctic Ocean Hydrographic Expedition in 1913 and was named Tsesarevich Alexei Island (),The Arctic Ocean Hydrographic Expedition 1910-1915 after Tsesarevich Alexei Nikolaevich, the son of Tsar Nicholas II of Russia. Following the 1917 October Revolution the island was renamed "Maly Taymyr". In 2005 a request was forwarded to the local government in Krasnoyarsk Krai in order to reinstate its former name to the island.

The ships are intended to undertake coastal hydrographic survey, required for production of nautical charts and publications aimed at improving navigation through waters closer to coasts. The ships are also capable of limited coastal defence role in an emergency, limited search and rescue and limited ocean research. The ships are equipped with standard hydrographic survey equipment such as advanced electronic positioning system, multi-beam swath sounding systems and sub-bottom profiler. The ships also carry two survey motor boats along with Kongsberg Maritime's Hugin 1000 Autonomous underwater vehicle (AUV) for closer investigations.

1913 Russian Hydrographic Service map showing the route of the expedition. A. N. Zhokhov. The Arctic Ocean Hydrographic Expedition (GESLO) (1910–1915) was a scientific expedition organized by Russia for the purpose of the development of the Northern Sea Route. This expedition accomplished its goal of exploring the uncharted areas of the continental side of the Northern Sea Route in what was seen as the culmination of the Great Northern Expedition, an ambitious enterprise initially conceived by emperor Peter I the Great to map the whole of the northern coast of Russia to the east.

The Arctic Ocean Hydrographic Expedition moved along the northern waters of Siberia from East to West. This expedition completed the cartography and description of the Northern coast of Eastern Siberia and its many islands. It also gathered a large quantity of data on currents, ice conditions, climate, and magnetic phenomena.William Barr: Tsarist Attempt at Opening the Northern Sea Route: The Arctic Oeean Hydrographie Expedition, 1910-1915} In 1913 the hydrographic expedition of the Arctic Ocean discovered the large Emperor Nicholas II Land —now Severnaya Zemlya (Northern Land), the last significant geographical discovery on the globe.

Alexander Dalrymple, the first Hydrographer of the Navy in the United Kingdom, appointed in 1795. The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices.

National organizations, particularly navies, realized that the collection, systematization and distribution of this knowledge gave it great organizational and military advantages. Thus were born dedicated national hydrographic organizations for the collection, organization, publication and distribution of hydrography incorporated into charts and sailing directions. Prior to the establishment of the United Kingdom Hydrographic Office, Royal Navy captains were responsible for the provision of their own charts. In practice this meant that ships often sailed with inadequate information for safe navigation, and that when new areas were surveyed, the data rarely reached all those who needed it.

Seasonal melting of sea ice causes an influx of lower salinity water into the middle and other shelf areas, causing stratification and hydrographic effects which influence productivity. In addition to the hydrographic and productivity influence of melting sea ice, the ice itself also provides an attachment substrate for the growth of algae as well as interstitial ice algae. Some evidence suggests that great changes to the Bering Sea ecosystem have already occurred. Warm water conditions in the summer of 1997 resulted in a massive bloom of low energy coccolithophorid phytoplankton (Stockwell et al. 2001).

The 2002 Maritime Forces Review identified a number of roles that other government agencies required the RNZN to undertake. Approximately 1,400 days at sea are required to fulfil these roles annually. Roles include patrolling the exclusive economic zone, transport to offshore islands, and support for the New Zealand Customs Service. The RNZN formerly produced hydrographic information for Land Information New Zealand under a commercial contract arrangement, however with the decommissioning of the dedicated Hydrographic survey ship HMNZS Resolution this has lapsed and the Navy now focuses on military hydrography.

The formation of neutral density surfaces from a given hydrographic observation requires only a call to a computational code that contains the algorithm developed by Jackett and McDougall. The Neutral Density code comes as a package of Matlab or as a Fortran routine. It enables the user to fit neutral density surfaces to arbitrary hydrographic data and just 2 MBytes of storage are required to obtain an accurately pre-labelled world ocean. Then, the code permits to interpolate the labeled data in terms of spatial location and hydrography.

The United Kingdom Hydrographic Office (UKHO) is the UK's agency for providing hydrographic and marine geospatial data to mariners and maritime organisations across the world. The UKHO is a trading fund of the Ministry of Defence (MoD) and is located in Taunton, Somerset, with a workforce of approximately 900 staff. The UKHO is responsible for operational support to the Royal Navy and other defence customers. Supplying defence and the commercial shipping industry, they help ensure Safety of Life at Sea (SOLAS), protect the marine environment and support the efficiency of global trade.

She then moved on to Brunswick, Georgia, where she arrived on 22 January 1937. There she received additional minor alterations and took aboard fishing gear and hydrographic equipment. She departed Brunswick on 30 January 1937 bound for New Orleans, Louisiana. Although her small size limited her to operations within of the United States Gulf Coast and precluded lengthy stays at sea, Pelican arrived at New Orleans well equipped for deep-water hydrographic and biological surveys thanks to the work performed on her at Fairhaven, Curtis Bay, and Brunswick.

In 1881, Gicquel des Touches worked as Director General of deposit maps and Navy planes, at the University of Paris. He also served as Chairman of the Hydrographic Committee (Members: Pierre Gaussin, Chief Hydrographer Engineer; Louis Lanneau, Charles Layrle, ship captains, Eugene Manen, hydrographic engineer, François Boullet, Assistant Engineer hydrographer Secretary); Vice-President of the Lighthouse Commission (Members: Paul Auguste Buret Rear Admiral, Émile Zédé Rear Admiral Peter Gaussin, Chief Hydrographer Engineer). He left active duty in May 1884 and dedicated time in his retirement to charitable works for Mariners.

During the 19th century, many maritime nations established hydrographic offices to provide means for improving the navigation of naval and merchant vessels by providing nautical publications, nautical charts, and other navigational services. There were substantial differences in hydrographic procedures charts, and publications. In 1889, an International Maritime Conference was held at Washington, D.C., and it was proposed to establish a "permanent international commission." Similar proposals were made at the sessions of the International Congress of Navigation held at Saint Petersburg in 1908 and the International Maritime Conference held at Saint Petersburg in 1912.

HMS Waterwitch, a hydrographic survey vessel Even though, in places, hydrographic survey data may be collected in sufficient detail to portray bottom topography in some areas, hydrographic charts only show depth information relevant for safe navigation and should not be considered as a product that accurately portrays the actual shape of the bottom. The soundings selected from the raw source depth data for placement on the nautical chart are selected for safe navigation and are biased to show predominately the shallowest depths that relate to safe navigation. For instance, if there is a deep area that can not be reached because it is surrounded by shallow water, the deep area may not be shown. The color filled areas that show different ranges of shallow water are not the equivalent of contours on a topographic map since they are often drawn seaward of the actual shallowest depth portrayed.

Hilly areas cover 14% of the territory while 86% is a plain or valley. Jonacatepec belongs to the Rio Balsas hydrographic region and is within the Atoyac River basin. The River Amatzinac begins near Amayuca, which later forms the River Tepalcingo.

NLV Pharos is based in Oban and works mainly in Scottish and Manx waters, servicing over 200 automatic lighthouses, buoys and beacons. She is also able to carry out hydrographic surveying and wreck finding and other commercial work under contract.

Not only had Whidbey performed significant and helpful medical services to and for the islanders of the Trust Territories, but she had also gathered useful hydrographic data in the course of her cruises throughout the many isles of the territories.

The cruises serve to collect hydrographic, nutrient and carbon concentration, primary productivity and other biogeochemical observations throughout the entire water column (surface to 1300m) (Astor et al., 2003; Astor et al., 2005; Muller- Karger et al., 2001; Muller-Karger et al.

An 1845 Admiralty Chart of the Houtman Abrolhos, Australia, surveyed from HMS Beagle Admiralty charts are nautical charts issued by the United Kingdom Hydrographic OfficeUK Hydrographic Office (UKHO) and subject to Crown Copyright. Over 3,500 Standard Nautical Charts (SNCs) and 14,000 Electronic Navigational Charts (ENCs) are available with the Admiralty portfolio offering the widest official coverage of international shipping routes and ports, in varying detail. Admiralty charts have been produced by UKHO for over 200 years, with the primary aim of saving and protecting lives at sea. The core market for these charts includes over 40,000 defence and merchant ships globally.

In 1861, on the outbreak of the Civil War, the family returned to Washington, D.C. and Patterson returned to federal service, this time as a civilian hydrographic inspector in the Coast Survey. The Hydrographic Inspector was in charge of the charting and marine survey work, and that office was traditionally held by a naval officer. Patterson's experience and good connections let him step into the role smoothly. During the Civil War, the role of the Coast survey included preparing charts and other material to help Naval ships execute the blockade of Southern ports (the strategy known as the "Anaconda Plan").

Captain Spratly occasionally submitted navigational routes and survey information to The Nautical Magazine and the Naval Chronicles. On 29 March 1843, Spratly sighted what is now known in English as Spratly Island and Ladd Reef.MARITIME BRIEFING, Volume I, Number 6: A Geographical Description of the Spratly Island and an Account of Hydrographic Surveys Amongst Those Islands, 1995 by David Hancox and Victor Prescott. Pages 14–15 Richard Spratly was the name reported by Captain Doyle of Australia and Captain Campbell of the Hydrographic Office His sighting was reported in The Nautical Magazine in the year 1843, issue 697:.

Candidates are not restricted from meals and are fed breakfast, lunch and dinner. The remaining three weeks involve the acquisition of various methods of conducting hydrographic surveys and creating a hydrographic chart while still participating in timed runs and swim tests. Because of its particularly challenging requirements, many candidates begin questioning their decision to come to BUD/S during First Phase, with a significant number deciding to Drop on Request (DOR). The tradition of DOR consists of dropping one's helmet liner next to a pole with a brass ship's bell attached to it and ringing the bell three times.

The or Ulleung Basin (울릉분지 ulleung bunji) is an oceanic basin located where the Sea of Japan meets the Korea Strait. It lies immediately south of Ulleung- do and Liancourt Rocks, in the eastern end of the South Korean EEZ and the western end of the Japanese EEZ. In 1978, the Japanese government registered the name "Tsushima Basin" with the International Hydrographic Bureau. In April 2006, Japan's plans to survey the region and South Korea's plans to register the name "Ulleung Basin" with the International Hydrographic Bureau resulted in a diplomatic standoff between the two countries.

Acquired by Canada in 1902 Gulnare was refitted and used for tidal and current survey work on the East Coast and the lower Saint Lawrence River. As one of the ships in the Canadian Hydrographic Survey, she was transferred from the Department of Marine and Fisheries to the Department of Naval Service when the latter was created in 1910. In 1912 she was transferred from survey work to duties as a tender and relief lightship in the lower Saint Lawrence River. Meehan, "The Hydrographic Survey of Canada from its Formation to the First World War 1904–1914", pp.

Navy Captain (later Commodore) Joseph Abulu was the first Military Administrator of Anambra State in Nigeria from 27 August 1991 to 1 January 1992 after the Enugu State had been split from the old Anambra during the military regime of General Ibrahim Babangida. Joseph Abulu graduated with a BSc in Geography. He joined the Navy in 1973, and trained in Basic Hydrography in India and in Hydrographic Engineering, Oceanography and Marine Environment in the Naval Oceanographic Office, United States in 1976. He commanded the Nigerian Navy Hydrographic ship before being appointed Hydrographer of the Navy (1986–1991).

Image used in the hydrographic shop and on the trade cards of the Roux family The Roux Family of Marseilles was a family of hydrographers and marine painters that specialized in ship portraits. While many generations were involved in the hydrographic business, it was really only three generations who painted and became known for their skill and accuracy in portraying a ship, making their work seem more like a photograph than a painting.Gulliver (1930), pp. 121-122 The painters in the family were Joseph, Ange-Joseph Antoine, Mathieu-Antoine, Ursule-Josephine, François Joseph Frédéric and François Geoffroi.

The required precision and accuracy of the hydrographic echo sounder is defined by the requirements of the International Hydrographic Organization (IHO) for surveys that are to be undertaken to IHO standards. These values are contained within IHO publication S44. In order to meet these standards, the surveyor must consider not only the vertical and horizontal accuracy of the echo sounder and transducer, but the survey system as a whole. A motion sensor may be used, specifically the heave component (in single beam echosounding) to reduce soundings for the motion of the vessel experienced on the water's surface.

The Ruisseau du Lac au Lard stream is a tributary of the west bank of the Jeannotte River, flowing in the western hydrographic slope of the Batiscan River, in the territory of the city of La Tuque, in the administrative region of Mauricie, in Quebec, in Canada. This river crosses the zec de la Bessonne. This hydrographic slope is served by the forest road R040, a bridge spanning the Lac au Lard stream, near its mouth. Since the mid-19th century, forestry has been the predominant activity of the Lac au Lard stream watershed; recreational activities, second.

The Doucet River is a tributary of the southern shore of Lac au Lard, in the hydrographic slope of the Jeannotte River, in the territory of the town of La Tuque, in the administrative region of Mauricie, in Quebec, in Canada. This river flows in the zec de la Bessonne. The course of the Doucet River descends on the west side of the Batiscan River and on the east side of the Saint- Maurice River. This river is part of the hydrographic side of the Batiscan river which generally winds south to the north shore of the St. Lawrence River.

Thomas Henry Tizard (1839 – 17 February 1924) was an English oceanographer, hydrographic surveyor, and navigator. He was born in Weymouth, Dorset and educated at the Royal Hospital School, Greenwich, at that time noted for its advanced mathematical training. He entered the Royal Navy by competitive examination as master's assistant in 1854 and served in the Baltic during the Crimean war. In 1860 he was promoted second master and commenced surveying in the Rifleman Reed, during which time he commanded the tender Saracen for three years.The Admiralty Hydrographic Service, 1795-1919 By Sir Archibald Day, Dawson, Llewellyn Stiles, Great Britain.

The Naval Hydrographic and Oceanographic Service ( or SHOM) is a French public establishment of an administrative nature () administered by the Ministry of Defence. It is the successor to the Dépôt des cartes et plans de la Marine, founded in 1720 which became the Naval Hydrographic Service in 1886 and the Naval and Oceanographic Service in 1971. Its present form was set up by decree number 2007-800 on 11 May 2007.Decree number 2007-800 of 11 May 2007 Its board is presided over by the Chief of Staff of the French Navy () and the body is directed by a director-general.

She was the second U.S. Exchange Hydrographer with the Canadian Hydrographic Service, spending three months on Canadian ships working with field parties in Newfoundland and the Canadian Arctic. After the exchange program, she was responsible for reviewing, critiquing, and determining whether the hydrographic survey data submitted by Atlantic Marine Center field units was complete and adequate for final acceptance into the processing system. Afterward, as assignment coordinator for the Office of NOAA Corps Operations, she worked with all program areas of NOAA, providing sound advice to both programs and officers regarding officer assignments. Rear Admiral Fields retired 1 December 2003.

The International Hydrographic Bureau was established in 1921 for the purpose of providing a mechanism for consultation between governments on such matters as technical standards, safe navigation and the protection of the marine environment. In 1970 the name was changed to the International Hydrographic Organization (IHO). The IHO is actively engaged in developing standards and interoperability, particularly in relation to the challenges brought about by digital technologies. In 2005 the IHO adopted the concept of a World Hydrography Day, which was "welcomed" by the United Nations General Assembly in Resolution A/RES/60/30 Oceans and the law of the sea.

By the eighteenth century better maps had been made and part of the objective of James Cook on his voyages was to further map the ocean. Scientific study has continued with the depth recordings of the Tuscarora, the oceanic research of the Challenger voyages (1872–1876), the work of the Scandinavian seamen Roald Amundsen and Fridtjof Nansen, the Michael Sars expedition in 1910, the German Meteor expedition of 1925, the Antarctic survey work of Discovery II in 1932, and others since. Furthermore, in 1921, the International Hydrographic Organization was set up, and it constitutes the authority on hydrographic surveying and nautical charting.

The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970, as part of a new international Convention on the IHO adopted by the then member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, when a revision to the Convention on the IHO entered into force. Thereafter the IHB became known as the "IHO Secretariat", comprising an elected Secretary-General and two supporting Directors, together with a small permanent staff (17 as at August 2019), at the Organization's headquarters in Monaco.

The hydrographic slope of Lake Faillon is mainly served by a forest road that goes north-east on the north bank of the Mégiscane River. The southwestern part of the lake is served by another branch of the forest road that runs east.

Due to the altitude, this lake is normally frozen from late October to early May; however, the safe period for traffic on the ice is usually from late November to April. A forest road serves the hydrographic slope of Grand lac des Enfers.

The Ferrer Rocks () are a group of rocks in Gerlache Strait lying between Ketley Point, Rongé Island, and Useful Island. They were charted by the Chilean Antarctic Expedition (1950–51) and named for Lieutenant Fernando Ferrer Fouga, hydrographic officer on the Angamos.

The hydrographic slope of lake Pascagama is accessible through some forest roads serving several peninsulas. The surface of the river is usually frozen from early November to the end of April, however, safe ice circulation is generally from early December to mid-April.

This may be because it is not detected by coastal observers either because it actually does not occur due to high water temperatures and/or other hydrographic barriers, or the migration may occur farther offshore and possibly deeper due to unusual conditions.

In late 2001, Melville began to operate in support of border protection operations in addition to her normal hydrographic duties.Bateman et al., in Rothwell & VanderZwaag (eds.), Towards principled ocean governance, p. 130 In January 2002, Melville was repainted from white to grey.

Mission planners may not know if a given force can move over a specific route. These variables may be hydrographic, meteorological, and geographic. SR teams can resolve trafficability or fordability, or locate obstacles or barriers. MASINT sensors exist for most of these requirements.

It was called "Mt. Beautemps" by La Perouse (1786, atlas), "Mte. Buen-tiempo" by Galiano (1802, map 3), "Gor[a]-Khoroshy-pogody" on Russian Hydrographic Dept. Chart 1378 in 1847, and "G[ora] Fayerveder" by Captain Tebenkov (1852, map 7), Imperial Russian Navy.

SSSI offers a certification program to enable members and non-members to gain recognition of their competencies through a formal “portfolio-based” process. Certifications are available for general competencies and specialist competencies including spatial information, hydrographic surveying, remote sensing, and engineering surveying.

In 1916 the company built two large mine countermeasures steamers, which were one year after followed by two nearly alike vessels. In 1917 the company started to build a diesel-powered vessel for the Russian Hydrographic Office. The company headcount exceeded 1,500 people.

The Sutlej and its tributary, the Buddha Nala, constitute the chief hydrographic features of the district. A brief description of these is as follows. ; Sutlej River: originates from Lake Manasarovar in Tibet. After flowing through Himachal Pradesh, it debouches from the Shivaliks.

In 1918 he was transferred to the Odessa Hydrographic Department. In November 1919 he set out from Odessa to Vladivostok on the transport ship Iyerusalim. In Vladivostok he sided with the Red Army. During the Japanese intervention in Siberia he went underground.

Washington: Hydrographic Office. It lies 7 km east of the Antamlan Peninsula (also known as Khmitevsky), the southernmost peninsula enclosing the Taui Bay (Тауйская губа; Tauyskaya Guba) from its western side. Administratively these islands belong to the Magadan Oblast of the Russian Federation.

They examined hydrographic data submitted by Royetski on the spot and made the final decision to recommend a line to cross the river Ob on the local cattle wade. That’s how they selected the construction site for the first railway bridge across the Ob River.

The International Hydrographic Organization defines the southern limit of the gulf as "A line running from Ras Muhammed (27°43'N) to the South point of Shadwan Island (34°02'E) and thence Westward on a parallel (27°27'N) to the coast of Africa".

76 Rockwell's survey was extremely detailed, including 17,782 hydrographic soundings. His work helped open the port of Portland to commerce.Stenzel, pp. 37–39 In the second half of the 19th century, the USACE dredged channels and built locks and levees in the Willamette's watershed.

Since ca. 2003–2005, DTMs have become more accepted in hydrographic practice. Satellites are also used to measure bathymetry. Satellite radar maps deep-sea topography by detecting the subtle variations in sea level caused by the gravitational pull of undersea mountains, ridges, and other masses.

The yacht was used by the former King mainly for fishing, but as his health declined, it was used as an auxiliary patrol craft, and hydrographic ship. After the death of Tāufaʻāhau Tupou IV, the yacht was occasionally used by his son, George Tupou V.

The protocol is most commonly supported by hydrographic sensors (level and flow), water quality sensors, meteorological instruments, soil moisture and plant physiology. Less common but also known to be supported are sensors for the measurement of solar radiation, tilt (inclinometers), and other geophysical parameters.

The operating units build on operational plans. The tactical units include detachments, training centers and forces of the army at the battalion level. The combat recognition and transport groups make up the Air Force tactical unit. The Navy uses transport and hydrographic tactical units.

The IHO enjoys observer status at the United Nations, where it is the recognised competent authority on hydrographic surveying and nautical charting. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards and specifications that are normally used.

The Casiquiare canal – Orinoco River hydrographic divide is a representation of the hydrographic water divide that delineates the separation between the Orinoco Basin and the Amazon Basin. (The Orinoco Basin flows west- north-northeast into the Caribbean; the Amazon Basin flows east into the western Atlantic in the extreme northeast of Brazil.) Essentially the river divide is a west-flowing, upriver section of Venezuela's Orinoco River with an outflow to the south into the Amazon Basin. This named outflow is the Casiquiare canal, which, as it heads downstream (southerly), picks up speed and also accumulates water volume. The greatest manifestation of the divide is during floods.

At the conclusion of 2006 those involved in Australia on the Map: 1606–2006 came to the realisation that there were significant limitations to Australian's knowledge of their early history. It was recognised that there needed to be ongoing education and awareness raising of the Australian community to overcome this limitation. At the same time the Australasian Hydrographic Society saw a need for greater awareness of hydrographic history and heritage among its members and stakeholders. Consequently, they invited those involved in Australia on the Map: 1606–2006 to form a new history and heritage ‘region’, to be known as Australia on the Map Division.

Lake of Banyoles Tossa de Mar, Costa Brava Most of Catalonia belongs to the Mediterranean Basin. The Catalan hydrographic network consists of two important basins, the one of the Ebro and the one that comprises the internal basins of Catalonia (respectively covering 46.84% and 51.43% of the territory), all of them flow to the Mediterranean. Furthermore, there is the Garona river basin that flows to the Atlantic Ocean, but it only covers 1.73% of the Catalan territory. The hydrographic network can be divided in two sectors, an occidental slope or Ebro river slope and one oriental slope constituted by minor rivers that flow to the Mediterranean along the Catalan coast.

At the time of Peter I hydrographic surveys were carried out following personal decrees of the emperor through the General admiral. Hydrographic tasks were always performed by Naval officers, who from 1724 onward began to work under instructions from the Admiralty Board. By 1746 important matters concerning hydrography were entrusted to Fleet Captain Alexey Nagayev who compiled the first atlas of the Bering Sea, as well as of the Baltic Sea in 1752. Nagayev's charts were very detailed for its time and, despite a few shortcomings, his atlas of the Baltic Sea was republished in 1757, 1788, 1789 and 1795, serving Russian mariners for more than 50 years.

This unnamed footpath extends in the same general direction as the road, and was followed as far as 150 m. However, it seems to disappear about 400 meters before reaching Destierro River.Ibid.: 43 Both the Iroquois and Pocora causeways offered formalized, controlled, and ceremonial access to the central part of Las Mercedes-1 architectural complex. The roads go in opposite directions from the center of the site along a route perpendicular to the hydrographic system. The geographic context of Las Mercedes-1, located between streams and rivers on all sides, has raised the question of whether the sphere of influence of a chiefly political center might be bounded by hydrographic systems.

The boundary of Port Shelter has different definition according to different sources. Publication of the U.S. Hydrographic Office, had stated the western shores of Keui Island (now known as Kau Sai Chau) and Jin Island, as well as eastern and north-east shores of the mainland area (now HKUST, Tseung Kwan O New Town and Clear Water Bay Peninsula), were the boundaries of Port Shelter. The Hydrographic Office also stated the entrance of the harbour lies between Lung Ha Wan (; located in Clear Water Bay Peninsula) and [a] Peaked Rock , with a width of about . Earlier publication of the Office, had stated the peaked rock is located south of Jin Island.

Therefore, a hydrographic survey may include the accurate positions and representations of hills, mountains and even lights and towers that will aid in fixing a ship's position, as well as the physical aspects of the sea and seabed. Hydrography, mostly for reasons of safety, adopted a number of conventions that have affected its portrayal of the data on nautical charts. For example, hydrographic charts are designed to portray what is safe for navigation, and therefore will usually tend to maintain least depths and occasionally de-emphasize the actual submarine topography that would be portrayed on bathymetric charts. The former are the mariner's tools to avoid accident.

The U.S. Navy transferred Helianthus to the United States Coast and Geodetic Survey on 28 March 1919. Commissioned as USC&GS; Helianthus, she served as a survey launch during her years with the Coast and Geodetic Survey, conducting hydrographic survey work primarily in the waters of the Territory of Alaska. After undergoing repairs, Helianthus began survey operations. Her first survey season was in 1920, during which she served along with another former U.S. Navy section patrol boat, USC&GS; Scandinavia, and a launch as a tender to the survey ship USC&GS; Explorer in triangulation, topographic and hydrographic surveys in Stephens Passage in the Alexander Archipelago in Southeast Alaska.

In XIXth Century, recreotourism activities took off. Due to the altitude, this lake is normally frozen from late October to early May; however, the safe ice circulation period is usually from early December to April. A forest road serves the hydrographic slope of Grand lac des Enfers.

Broch completed his primary education in 1900 and served one year in the nation's military. Beginning in 1901 he studied zoology at the University of Christiania under Kristine Bonnevie. He became the first assistant at the Swedish Hydrographic- Biologiska Kommissionen during the latter part of his study.

Skrebtsova Island Skrebtsova Island, popularly known as Kovrizhka ("honey- cake"), is an island in the Amur Bay, Sea of Japan, 2 km north-west of the coast of Vladivostok. Named in 1863 in honor of M. L. Skrebtsova who participated in hydrographic research of Peter the Great.

One hydro-oceanographic and three hydrographic ships help carrying out mapping and research operations, as well as gathering intelligence which could prove useful to the deployment of naval forces and their weapon systems. They are operated by the service hydrographique et océanographique de la marine (SHOM).

He made a hydrographic chart of the coast of France for Francis, Duke of Guise. Nothing is known of his life after the creation of the 1553 map; the Dictionnaire de biographie française suggests that he died after 1574, but none of its sources support this statement.

The bottom line is that MASINT cannot identify who is inside a tank or aircraft of interest. Numerous countries produce their own antisubmarine warfare sensors, such as hydrophones, active sonar, magnetic anomaly detectors, and other hydrographic sensors that are frequently considered too "ordinary" to be called MASINT.

The Hydrographic Service has the operational responsibility for the international electronic navigational chart centre Primar, based in Stavanger. Distribution Service The Distribution Service is responsible for publishing analog and digital maps, and to provide mapping services to the public and partners of the Norway Digital consortium.

Rice cultivation is also done on the northern and eastern regions of the reservoir bank. The reservoir has numerous islands, namely Russkij, Bolshoy, Sen’kina, Krolichij, Zherebkov, and Darzhinskij. The hydrographic web is weakly developed. The reservoir is situated between the Sal’sko-Manychevskoja Ridge and Stavropolskaja Hills.

A hydrographic survey is quite different from a bathymetric survey in some important respects, particularly in a bias toward least depths due to the safety requirements of the former and geomorphologic descriptive requirements of the latter. Historically, this could include echosoundings being conducted under settings biased toward least depths, but in modern practice hydrographic surveys typically attempt to best measure the depths observed, with the adjustments for navigational safety being applied after the fact. Hydrography of streams will include information on the stream bed, flows, water quality and surrounding land. Basin or interior hydrography pays special attention to rivers and potable water although if collected data is not for ship navigational uses, and is intended for scientific usage, it is more commonly called hydrometry or hydrology.

The wide passage between Cape Horn and Livingston Island is the shortest crossing from Antarctica to another landmass. The boundary between the Atlantic and Pacific Oceans is sometimes taken to be a line drawn from Cape Horn to Snow Island ( north of mainland Antarctica), though the International Hydrographic Organization defines it as the meridian that passes through Cape Horn--67° 16′ W.International Hydrographic Organization, Limits of Oceans and Seas, Special Publication No. 28, 3rd edition, 1953 , p.4 Both lines lie within the Drake Passage. The other two passages around the extreme southern part of South America (though not going around Cape Horn as such), the Strait of Magellan and Beagle Channel, are narrow, leaving little maneuvering room for a ship.

During 2009 and January 2010, the NATO fleet in the Gulf of Aden was commanded by the Portuguese Navy, who received the award of "exceptional bravery at sea" from the International Maritime Organization for its successful attacks on pirate activity, conducted by Corte Real during the peak of pirate activity. In parallel with its military roles, the Portuguese Navy continued to assume an important scientific role, mainly in the scope of the oceanographic and hidrographic research. The scientific missions of the Navy are led by the Hydrographic Institute, with the support of the Hydrographic Ships Group. One important role in this area is the support to the Mission for the Extension of the Continental Shelf of Portugal, that has been given since 2004.

An electronic display showing the tide forecast in Piazzale Roma during the acqua alta of December 1, 2008. The Tide Monitoring and Forecast Centre of the City of Venice is fed information via a network of hydrographic stations, located in both the lagoon and the Adriatic Sea (on a scientific platform belonging to the Italian National Research Committee, CNR). The centre's unique expertise on the phenomenon enables it to produce forecasts of remarkable accuracy, usually for the following 48 hours (longer forecasts are also issued, but tend to be less reliable, as discussed above), by analysing the meteorological and hydrographic data available. Forecasts are then announced to the population via the centre's website and dedicated phone lines, through local newspapers, on electronic displays, and at some stops of the vaporetti (public transport).

In 1926 the Ebro Hydrographic Confederation was created in Caspe, an organization that manages the waters and irrigation of the Ebro hydrographic basin, the most important of the ten that have been created in the peninsular territory. Already proclaimed the Second Spanish Republic, the draft of the Statute of Autonomy of Aragon of 1936 was drafted in this city, also known as the Statute of Caspe, which was not ratified by the Cortes at the outbreak of the Spanish Civil War. During the first part of the war, Caspe was the seat of the Council of Aragon, a government body created by the anarchists in 1936. This entity continued its functions until it was dissolved by government authorities in the summer of 1937, due to its independence from the Republican government.

Darrell Bay, formerly Shannon Bay, is a bay and associated ferry terminal and unincorporated settlement on the northeast coast of Howe Sound to the south of Squamish, British Columbia, Canada. It is adjacent to Shannon Falls Provincial Park, which lies immediately across BC Highway 99 (the Sea to Sky Highway). Known locally as Shannon Bay until 1949, after William Shannon, one of the original landholders in the vicinity and the namesake of Shannon Falls, it was renamed by the Hydrographic Service as the result of a petition from Darrell Burgess, who owned a fishing camp at this spot (the locality was already known as Burgess Camp, though the bay was Shannon Bay). No reason was indicated why the established local name was not submitted by the Hydrographic Service.

Triangulation and navigation bases were established along with tide gauges and then topographic and hydrographic surveys were begun. Inshore hydrography was done by "the whaleboat and alco-vapor launch" while offshore survey to 20 fathoms was done by casting the lead and in deeper water by the sounding machine. In 1910 the Research was one of five C&GS; vessels surveying in the Philippines, the others being Pathfinder, Romblon, Marinduque and Fathomer all except Pathfinder being owned and largely funded, excepting pay of the USC&GS; officers, by the Philippine Government. The ship engaged in hydrographic surveys, including work in the Tanon Strait but spent much of its time supporting shore parties engaged in triangulation and topographic surveys of the south coast of Masbate Island, the north coast of Leyte, the west coast of Samar.

During 1913–1915 Research worked in San Bernardino Strait, the northern part of the Samar Sea and in southern Luzon, Ticao Island and Masbate Island with triangulation, hydrographic and topographic surveys. The ship underwent repairs and outfitting in Manila December 24, 1912 through late February 1913 and again between January 1, 1915 and March 16, 1915 after which proceeded to work in and around Sorsogon Bay, southern Luzon. Triangulation work to link Luzon and Ticao and Masbate Islands completed, the ship's parties began topographic and then hydrographic surveys undertaken by ship's launches and the ship. In 1918, due to both funding issues and loss of C&GS; officers to Army and Navy or sent back to the United States, the Marinduque and Research were recalled and laid up.

In July 2001, NOAA's Office of Ocean Exploration asked Whiting to search for the wreck of the U.S. Navy submarine , which sank 15 nautical miles (28 km) off Cape May, New Jersey, in September 1920. Whiting, which had just completed a summer in port at Norfolk, Virginia, and was bound for Boston, Massachusetts, to conduct hydrographic survey operations in New England, paused off Cape May in late July 2001 to search for the wreck. Whiting's survey department approached the project as it would any typical hydrographic survey. Information on snags – obstructions on the ocean bottom that snarl fishing nets and gear – that local recreational fishermen had reported and reports of possible locations of the wreck from divers that had visited it provided Whiting with possible targets for her search.

In 1914, Libertad was assigned to train the crews for the new dreadnought battleships being built in the United States (Rivadavia and Moreno). In 1915 the ship was reclassified as a "coast guard ship".

The hydrographic slope of Lake Soscumica is accessible via the James Bay Highway (North-South direction) to to the East. The west side of the lake is served by a winter road (North-South direction). The surface of the lake is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

The ship's assignments were typically to transport, deploy, retrieve and repair submarine cables. In later Naval service functions specified were towing a cable plow, a large devices used to bury cable in coastal areas to protect it from damage from trawls and other hazards. Additional functions not directly related to cable work were towing acoustic projectors and conducting acoustic, hydrographic, and bathymetric surveys.

Construction of Quest began in 1967 by Burrard Shipbuilding & Drydock Ltd. at Vancouver, the ship was launched on 9 July 1968. After entering service on 21 August 1969 with the hull number AGOR 172, Quest was deployed on the East Coast. The vessel was used primarily for oceanographic and hydrographic research in the north Atlantic Ocean and the Arctic Ocean.

The west coast of Madagascar.

Its hydrographic basin has an area of . It increases its volume between May and October, together with the rainy season. Its basin is affected by severe drought together with the El Niño phenomenon, and this is usually associated with severe bush fires. There are no dams built along the main course of the river to leave it to its natural health.

Much of the atoll was uncharted, so hydrographic data was collected as well. One of the newly discovered geographic features was named Ironwood Reef in honor of the ship. In 1967 the Republic of Vietnam had only a single buoy tender. It was not adequate to maintain and improve navigational aids needed by the increased US shipping activity along the South Vietnamese coast.

In 1935, she was ordered to French Indochina to collect hydrographic data in and around Saigon. She resumed Neutrality patrol in 1936, and by 1940 had served successively as station ship at Amoy and Swatow, China. From 7 July to 4 October, Parrott patrolled China waters based at Tsingtao and then made calls to other northern Chinese ports, returning to Manila 11 October.

Aubrey and Maturin read newspapers to learn world events while they were blockading Brest, and adjust to peace. They agree to a plan with three men from the Chilean independence movement. Aubrey requests suspension from the Navy List, and is put on loan to the hydrographic office. Maturin finances the fitting-out of the Surprise, which takes until February 1815.

NAVAREAs are the maritime geographic areas in which various governments are responsible for navigation and weather warnings. Map of all the NAVAREAs NAVAREAs are mentioned in International Maritime Organization Assembly Resolution A.706(17) adopted 6 November 1991.

The hydrographic slope of Lac Hébert is accessible via the forest road R1009 (North-South direction) serving the western part of the lake and the road R1053 (East-West direction) serving the eastern part of the lake. The surface of Lake Hébert is generally frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

The appraisal stage deals with the collection of information relevant to the proposed voyage as well as ascertaining risks and assessing the key features of the voyage. This will involve considering the type of navigation required e.g. Ice navigation, the region the ship will be passing through and the hydrographic information on the route. In the next stage, the written plan is created.

Numerous nautical publications are available on navigation, which are published by professional sources all over the world. In the UK, the United Kingdom Hydrographic Office, the Witherby Publishing Group and the Nautical Institute provide numerous navigational publications, including the comprehensive Admiralty Manual of Navigation. In the US, Bowditch's American Practical Navigator is a free available encyclopedia of navigation issued by the US Government.

Then he was a foreman on different HSs: "Iney" (photo), "Orlik", "Anna", "Priboy", "Toros", "Tsirkul". During this period, he discovered, documented, and photographed the skeleton of Peter Tessem, member of Amundsen's expedition aboard Maud. In 1925 Rybin was appointed magnetic deviation chief of the Ob basin. In 1927 he passed his exams and received an external degree from the Hydrographic college.

In 1945 the Baltic fleet was divided into 4th fleet, with the main base in Pillau, and 8th fleet, with the main base in Tallinn. Rybin was appointed the Chief of the 4th fleet hydrographic service, and moved to Königsberg. He entered the CPSU. With his family, he lived in a cottage, and used the Horch car with a sailor as a driver.

The hydrographic network includes numerous streams and springs. The river Golo rises from 1991 metres in the commune south of the Paglia Orba (2525 m) and 200 m to the south of the Capu Tafunatu (2335 m). Its course is interrupted by the Calacuccia Dam. It leaves the commune 200 metres upstream of the Mazzola bridge on the D218 road.

He then spent four years on the China Station. He trained as a Hydrographic Surveyor, and as a Lieutenant worked on the surveys of the Queensland coast and the New Hebrides, now Vanuatu, in the South Pacific, (, 1890–91). While in Vanuata he carried out ethnographical work, which was published in 1894. In 1893-4 he was surveying in the South Pacific with .

He retired on 2 August 1919. After his retirement he returned to the family home at Castletownshend, near Cork in Ireland. During his retirement He continued to work for the Admiralty, in the Hydrographic Department and on the Tidal Committee, and published several books including Ocean Passages for the World in 1923. He also published articles describing his surveying experiences in Blackwood's Magazine.

Graphic depicting hydrographic survey ship conducting multibeam and side-scan sonar operations Side-scan sonars can be used to derive maps of seafloor topography (bathymetry) by moving the sonar across it just above the bottom. Low frequency sonars such as GLORIA have been used for continental shelf wide surveys while high frequency sonars are used for more detailed surveys of smaller areas.

Researchers investigated ocean conditions, taking hydrographic measurements, recording meteorological and tidal data and monitored plankton. They observed the growth rate of the corals and the marine life around it. They collected specimens including plankton as well as conducting dredging and trawling around the reef. Trochus shell was collected and studied and at the time a trochus farming industry was proposed.

Prior to his role at NOAA, Gallaudet served as Oceanographer of the Navy and Commander of the Naval Meteorology and Oceanography Command. He has experience in weather and ocean forecasting, hydrographic surveying, developing policy and plans to counter illegal, unregulated, and unreported fishing, and assessing the national security impacts of climate change. Gallaudet retired from the Navy in July 2017.

By taking a weighted average of the four closest casts from the labeled data set, it enables to assign \gamma^n\, values to any arbitrary hydrographic data. Another function provided in the code, given a vertical profile of labeled data and \gamma^n\, surfaces, finds the positions of the specified \gamma^n\, surfaces within the water column, together with error bars.

The Marine Observatories are seated in Hakodate, Maizuru, Kobe and Nagasaki. These stations observe ocean waves, tide levels, sea surface temperature and ocean current etc. in the Northwestern Pacific basin, as well as the Sea of Japan and the Sea of Okhotsk basin, and provide marine meteorological forecasts resulted from them, in cooperation with the Hydrographic and Oceanographic Department, Japan Coast Guard.

In June 1848, Captain Owen Stanley undertook a ten- day hydrographic depth sounding survey of the Trinity Bay region. His consequent official map listed "Native Huts" at present-day Palm Cove, and "Many Natives" and "Native Village" on the stretch of coast immediately north. Green Island was marked "Low Bushes", and the future site of Cairns was indicated as "Shoal" and "Mangroves".

As is common with contemporary research vessels, Endeavour also carried out more than one kind of research, including comprehensive hydrographic survey work. Some other notable early research vessels were HMS Beagle, RV Calypso, HMS Challenger, USFC Albatross, and the Endurance and Terra Nova. The names of early research vessels have been used to name later research vessels, as well as Space Shuttles.

During September 1885, escorted by , she transported a cargo of gold bullion from New Orleans to Washington, D.C. In early 1886, she was assigned hydrographic duties fixing locations on the Puerto Rican coast. After subsequently cruising as far north as Halifax, Nova Scotia, Swatara arrived at the Portsmouth Navy Yard, Portsmouth, N.H., where she was decommissioned on 27 October 1886.

Put at the head of various political, commercial and scientific missions, he set out from Brest once again in February 1785 and spent the next seven years on difficult and perilous voyages in the Red Sea, Indian Ocean and the seas off China. In his funeral elogy for Rosily in 1830, the hydrographic engineer M. Beautemps-Beaupré witnessed to Rosily's hydrographic work during this time, though this work was superseded by that of others by the end of the 19th century. This work did, however, gain Rosily the rank of contre-amiral and (on 22 August 1795) that of director and inspector general of the naval charts and plans department. Rosily then commanded the forces in the port of Rochefort before being made vice-admiral on 22 September 1796 and carrying out various missions to Genoa, La Spezia, Boulogne and Antwerp.

From there she deployed for further hydrographic work in the western Pacific. Pioneer herself and her survey launches completed inshore hydrography of the project area on 28 May 1959, after which Pioneer conducted offshore hydrography controlled by LORAC and LORAN, beginning with an exploratory survey of the entire project area, followed by surveys for the location and routes of submarine cables. She completed the project in June 1959 and returned to Alameda on 23 June 1959. On 9 September 1959, Pioneer departed California, stopped at Pearl Harbor, Hawaii, and then proceeded to Kwajalein Atoll, where she performed hydrographic survey operations in support of a classified U.S. Navy project.

The peak was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos from 1957–59, and was named by the Advisory Committee on Antarctic Names for Commander Edgar A. Mohl, U.S. Navy, who was a hydrographic officer on the staff of the Commander, U.S. Navy Task Force 43, during Deep Freeze Operations I and II in 1955–56 and 1956–57.

Since the Meiji period, the Imperial Japanese Navy had carried out hydrographic survey with old naval vessels. While sufficient for routine peacetime survey duties, these obsolete vessels were deemed too slow for service in combat zones. Furthermore, these vessels were essentially fighting ships, thus were not able to carry many surveying devices. Therefore, in the 1920s and the 1930s, many of these ships were retired.

Mission Rock () is a low-lying rock lying southwest of the Guébriant Islands, off the south end of Adelaide Island, Antarctica. It was surveyed by the Royal Navy Hydrographic Survey Unit, 1962–63, and was so named by the UK Antarctic Place-Names Committee in 1963 because of the rock's proximity to the Guébriant Islands, which were named for the French missionary Father Jean Budes de Guébriant.

Pettersson became the first full professor of oceanography in Sweden and in 1938 founded the Institute of Oceanography in Gothenburg, thanks to funding from the Knut and Alice Wallenberg Foundation. Pettersson was its head until 1956. He also was the head of the Bornö Hydrographic Field Station on Stora Bornö. In 1956, aged 68, he became Professor of Geophysics at the University of Hawaii.

In 1956, the icebreaker spent five and a half months performing hydrographic surveys in the eastern Arctic. In 1957, the ship made port visits to Portsmouth, England, Oslo, Norway and Copenhagen, Denmark. Labrador was decommissioned on 22 November 1957 and transferred to civilian control in 1958. This was done with the condition that should the Royal Canadian Navy wish to take the ship back, they could.

The ship's maiden voyage took place from December 1929 to May 1931 and consisted of a hydrographic survey of the South Sandwich Islands. From October 1932 until May 1933 she operated in the Antarctic, calling at South Africa, Australia and New Zealand. Similar voyages took place from 1934 to 1939. Her last voyage before the onset of war was from September 1937 to May 1939.

Most of Acadias crew came from the Eastern Shore of Nova Scotia. Many served their entire careers aboard, an indication that she was regarded as a "happy ship". Many of her officers were from Newfoundland. As a hydrographic ship, the Hydrographer in Charge was the senior officer, deciding where Acadia went and what she did, while the Captain ran the ship's day-to-day operations.

CGS Cartier returned to her former service as a hydrographic survey vessel which included work on the Atlantic coast. Her ability to chart exact locations was used extensively to curb smuggling operations and Dominion law enforcement used her as a platform for anti-smuggling operations, resulting in timely searches of suspected smugglers. Notwithstanding this role, she was forever a survey vessel first and foremost.

Oscar Dyson has various laboratory capabilities. A wet laboratory, a dry laboratory, a biology laboratory, and a hydrographic laboratory all are situated on the starboard side of her main deck, while an electronics and computer laboratory are on the port side of her main deck. Her wet laboratory includes a climate-controlled space with a built-in chiler system. Oscar Dyson carries two boats.

Frank Evers Bed was appointed prosector. The official expedition artist was John James Wild. As well as Nares and Maclear, others that were part of the naval crew included Pelham Aldrich, George Granville Campbell, and Andrew Francis Balfour (one of the sons of Scottish botanist John Hutton Balfour). Also among the officers was Thomas Henry Tizard, who had carried out important hydrographic observations on previous voyages.

Petrus Plancius Instructing Students in the Science of Navigation, by David Vinckboons In 1592 Plancius published his best known world map titled "Nova et exacta Terrarum Tabula geographica et hydrographica"."New and exact geographic and hydrographic map of the world". He also published journals and navigational guides and developed a new method for determining longitude. He also promoted the Mercator projection for navigational maps.

The destroyer was detailed to carry out scientific tests, and formed Task Group 308.4. They were augmented by RAN vessels, designated Task Group 308.2. The sloop and boom defence vessel carried out a hydrographic survey of the Monte Bello Islands, laying marker buoys for moorings. Care had to be taken with this, as Operation Hurricane had left some parts of the islands dangerously radioactive.

In 1904, Merlin took part in the 4th expedition of the Somaliland Campaign against the Mad Mullah. The naval force included HM Ships , , , , and . From 1906, Merlin was employed as a survey ship, conducting hydrographic work both at home and abroad. She re-commissioned at Hong Kong on 5 November 1913, and continued to work as a survey vessel, for which her armament was reduced.

Lake Troïlus is of the Broadback River watershed, located in Baie-James, in the Nord-du-Québec, in the province of Quebec Canada. This body of water is part of the Assinica Wildlife Sanctuary. The surrounding areas are conducive to hunting and fishing.

In Vila Real, the plaza Diogo Cão was named after him. In the center of the plaza stands a bronze statue of him supported by a square granite pedestal base.Monument to Diogo Cão, Minube.net (accessed on 20 May 2019) In 1999, André Roubertou from the French Hydrographic Office (SHOM) named an undersea hole located off the southern coast of Portugal (Gulf of Cádiz) the Diogo Cão Hole.

South Point () is a point 1.75 nautical miles (3.2 km) southwest of Entrance Point, marking the southernmost point of Deception Island, in the South Shetland Islands. The point was charted by a British expedition 1828–31, under Foster. The name was proposed in 1949 by the Hydrographic Dept., Admiralty, following a survey of the island by Lieutenant Commander D.N. Penfold, Royal Navy, in 1948–49.

Hydrographic duties are handled by KD Perantau and KD Mutiara. A Naval Air Wing was also founded with the purchase of ex-Royal Navy Westland Wasps. Four ships of the RMN have been decommissioned and handed over to the Malaysian Maritime Enforcement Agency (MMEA). The vessels are patrol boats KD Lembing and KD Sri Melaka, and offshore patrol vessels KD Marikh and KD Musytari.

That section is called Wadi es-Sitt (valley of the lady) in Arabic,Palmer 1881, p. 156 The northern quarter was built in close proximity to a number of springs, including 'Ayn al Khalil, 'Ayn Nasir, 'Ayn Sitt Leila, and 'Ayn Jumma, collectively known as 'Uyun Seil Lajjun.State of Israel, Hydrographic list part 2, items no. 282-286,295. The eastern quarter was next to 'Ayn al Hajja.

In contrast, the rivers of the Mediterranean Basin are shorter, more seasonal, and make a precipitous descent from the mountains of the Baetic Cordillera. Their estuaries are small, and their valleys are less suitable for agriculture. Also, being in the rain shadow of the Baetic Cordillera means that they receive a lesser volume of water. The following hydrographic basins can be distinguished in Andalusia.

The hydrographic slope of the "Lake du Bras Coupé" is accessible through the forest road (East- West direction) serving the southern part of the Lake and along the north side the boundary of the townships of Lescure and Druillettes. The surface of Bras Coupé Lake is generally frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

Then on 27 July 1968, she headed east for a four-month deployment in the Mediterranean. There until the end of November 1968, she conducted hydrographic surveys along the coasts of southern Europe and North Africa. She was reassigned to Amphibious Squadron 6 while deployed to the Mediterranean. Ruchamkin was reclassified as an "amphibious transport, small", and redesignated LPR-89 on 1 January 1969.

When Bransfield returned to Valparaíso, he gave his charts and journal to Captain Shirreff, who delivered them to the Admiralty. The original charts are still in the possession of the hydrographic department in Taunton, Somerset, but Bransfield's journal has been lost. The Admiralty, it seems, was still more interested in the search for the Northwest Passage. Two private accounts of Bransfield's historic voyage were published during 1821.

He entered the United States Navy as a midshipman in 1818, and became a lieutenant in 1826. In 1833, for his survey of Narragansett Bay, he was placed in charge of the Navy's Department of Charts and Instruments, out of which developed the Naval Observatory and Hydrographic Office. Wilkes' interdisciplinary expedition (1838–1842) set a physical oceanography benchmark for the office's first superintendent Matthew Fontaine Maury.

The park contains the Lajeado Cruzeiro, a watercourse that has its sources around the park and its mouth near the flooded area of the Queimados River. The park's buffer zone is a strip around the park, extending to include small hydrographic basins that drain into the park. There are about 70 farms in the buffer zone growing various crops and raising dairy cattle, pigs, poultry and sheep.

In November 1941 Rybin was awarded a gold Swiss watch for the geodesical ensurence of the artillery shooting. The watch can now be seen in the museum of the Head Department of the Navigation and Oceanography. In 1944, after reconquering Estonia, the Baltic hydrographic service was moved to Tallinn (Kreuzwaldi 13). Rybin and his family (wife and son) lived on the fourth floor of the same building.

His daughter was born in 1946. His son studied at the Russian school in Toompea. The main task of the hydrographic service in 1944-1945 was the fastest putting the reconquered ports and navaids into operation. Thus, George Rybin with the mobile groups of the hydrographers, moved along the Baltic coast to south- west, took part in the East- Prussian operation and Konigsberg assault.

UK Hydrographic Office nautical charts; a 1908 edition is shown here. In 14–15 September 1774, Captain James Cook charted a "Sandy I." snaking between 19°–20° S latitudes and 163°50'–164°15' E longitude off the tip of New Caledonia. The associated map, titled "Chart of Discoveries made in the South Pacific Ocean…", was published in 1776.See David Rumsey Historical Map Collection.

During a 12 month attribution, HMS Enterprise provided the most days on task of any other unit and saved the most lives (9,100). In 2020, HMS Enterprise was ordered to sail from Crete to use her hydrographic survey expertise to help to re-open the port of Beirut following the massive explosion which devastated the port and surrounding area. She also delivered humanitarian aid.

Straddling the equator, islands in the chain are located in both the northern and southern hemispheres, with Volcán Wolf and Volcán Ecuador on Isla Isabela being directly on the equator. Española Island, the southernmost islet of the archipelago, and Darwin Island, the northernmost one, are spread out over a distance of .

INS Darshak was used to investigate historically significant shipwrecks off the coast of Tamil Nadu. This included exploring the submerged remains of the lost city of Poompuhar in Tamil Nadu. Darshak, under the command of Captain P. Jayapal, was deployed off Poompuhar, about north of Nagapattinam. The ship carried out an extensive hydrographic survey and diving operations in the area off the Tharangambadi coast.

Dergajen is located on the hydrographic divide between the Tekeze catchment in the west and the endoreic Afar basin to the east. The western part of Dergajen consists of gentle slopes descending in a western direction. These slopes have an elevation of 2400 to 2600 meters above sea level. The eastern part of the tabia consists of steep slopes, descending into the Afar lowlands.

Due to its hydrographic conditions, the Pascua River has a hydroelectric potential of great importance. There exists a controversial Endesa project to construct two massive power dams on the course of the river, but the proposal has generated immediate opposition from a great part of the population and in the government authorities, due to the serious ecological damage that would cause in the zone.

Between December 1924 and April 1926 he was named Chief of the Central Hydrographic Department of the USSR. From 1925 he commanded the Soviet Baltic Fleet and in 1932 was the founding commander of the Soviet Pacific Fleet. He became commander of the Soviet navy following the arrest of his predecessor. Viktorov was himself arrested at the end of 1937 and was shot in 1938.

By 1887, Troughton & Simms employed 200 people at their Charlton works. Military production began to be important with production of coincidence rangefinders for the British government. Among their clients were the Italian Navy, the Russian government and the Austro-Hungarian Hydrographic Department Observatory. Undated advertisements from this period include the claim that "in fifteen years our output of levels and theodolites alone was 23,000".

150th anniversary commemorative stamp, issued by the United States Post Office Department in 1957. Following World War II, the Coast and Geodetic Survey resumed its peacetime scientific and surveying efforts. In 1945 it adapted the British Royal Air Forces Gee radio navigation system to hydrographic surveying, ushering in a new era of marine electronic navigation. In 1948 it established the Pacific Tsunami Warning Center in Honolulu Hawaii.

Following conversion to a hydrographic survey ship, San Pablo was recommissioned on 17 September 1948 at San Francisco, California, with Commander T. E. Chambers in command.

Unlike most nations, CHS is not part of Canada's navy, but is rather a civilian scientific organization under the federal government's Department of Fisheries and Oceans (DFO) Science Sector. Most of the survey vessels employed by CHS are nominally crewed and operated by the Canadian Coast Guard, also part of DFO. CHS also works in collaboration with the Royal Canadian Navy and other ships and vessels of opportunity from other international hydrographic offices, primarily the US Office of Coastal Survey (OCS) of the National Ocean Service (NOS) of the National Oceanic and Atmospheric Administration (NOAA) and other academic and industry partners. The incumbent of the Director General of CHS position is also called the "Hydrographer General of Canada" to reflect the important liability associated with the responsibilities coming from the previous original title, "Dominion Hydrographer," which dates to the earliest days of hydrographic surveying in Canada.

From 1985 to 1988, Betano and Brunei were assigned to the Australian Hydrographic Officer and operated as survey ships in the waters of northern Australia and Papua New Guinea. The ship was deployed to East Timor as part of the Australian-led INTERFET peacekeeping taskforce from 19 January to 19 February 2000.Stevens, Strength Through Diversity, p. 15 Her service earned her the battle honour "East Timor 2000".

Melbourne did not participate in the Vietnam War, although RAN pilots were used to support RAAF and United States Army helicopter units. Following the decommissioning of Melbourne without replacement in the early 1980s, the Fleet Air Arm was reorganised to focus on helicopter operations from frigate-size ships, although fixed-wing aviation within the RAN continued with land-based aircraft used for patrols, electronic warfare training, transport, and hydrographic survey.

Mantienne, p.130 In 1799, the Englishman Berry witnessed the departure of the Nguyễn fleet, composed of three sloops of war commanded by French officers, each of them with 300 men, 100 galleys with troops, 40 war junks, 200 smallers ships, and 800 transport boats.Mantienne, p.129 Jean-Marie Dayot also did considerable hydrographic work, making numerous maps of the Vietnamese coast, which were drawn by his talented brother.

Since 1830, a great deal of national legislation has been enacted, with much of it addressing the acceptance or the rejection of the metric system. The United States Bureau of Standards was created by an Act of Congress on March 3, 1901. As mentioned above, the Coast Survey languished for 14 years from 1818 to 1832. In 1823, 1824, and 1825, the Navy Department tried to establish a hydrographic office.

Schule Island () is a small island lying 4 nautical miles (7 km) east of Laktionov Island, off the east side of Renaud Island in the Biscoe Islands. First accurately shown on an Argentine government chart of 1957. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 for John J. Schule, Jr., American oceanographer who organized the sea ice service of the U.S. Hydrographic Office in 1950.

Sanavirón Island () is an island lying off Northeast Glacier, southeast of Audrey Island, Debenham Islands, in Marguerite Bay on the Fallières Coast. It was charted by the Argentine Antarctic Expedition, 1950–51, as two small islands (probably because of overlying ice) and named "Islotes Sanavirón" after the Argentine ship Sanavirón, which was used for the hydrographic survey of the area. The feature has been determined to be a single island.

This included escape and evasion, land/maritime orientation, knife fighting, close-quarter combat, weapons and demolition, combat swimming, compass swims, hydrographic surveying, etc. Many of these Marines were exceptional marksman and sharpshooters. Most of these courses and training were conducted within the Marine's own training function. However, some were sent to train with the Royal Marines in England, and other specialized schools developed around the areas of the Pacific.

While most people think of navigation when they hear the term sextant, the instrument has been used in other professions. ;Navigator's sextant:The common type of instrument most people think of when they hear the term sextant. ;Sounding sextants:These are sextants that were constructed for use horizontally rather than vertically and were developed for use in hydrographic surveys. ;Surveyor's sextants:These were constructed for use exclusively on land for horizontal angular measurements.

O'Byrne, p86 It was in 1833 that Blackwood was appointed to be in command of HMS Hyacinth, a ship which would take him to Australia on his first visit and in which he would travel to the north-east coast to gather hydrographic data. In 1838 Blackwood received a promotion to the rank of captain. Whitsunday Island. Blackwood voyaged past here and chartered the area while aboard the Fly.

In 1910, she sailed from Penang for the Australia Station.The Mercury, Monday 23 May 1910, p.4. She undertook various hydrographic surveys around Australia and the South Pacific between 1910 and 1914. With the beginning of World War I, and the threat of German Empire expansion in the South Pacific, she sailed to Suva, Fiji with a cargo of coastal guns, for a gun emplacement on a hill in Suva.

Capitán Miranda was ordered in January 1930 from the Spanish Sociedad Española de Construcción Naval shipyard at Cádiz. The vessel was laid down on 3 March and launched on 27 July 1930. As a hydrographic vessel she displaced 552 tons, with an overall length of , and a beam of . Capable of , the ship was armed with a 37 mm cannon and a machine gun, and had a complement of 52.

In particular, the high-security laboratories were completely redesigned and have since then been among the safest in the world (biosafety level 4). The numerous decorative reliefs on the façade of the old building were created by the artist . The buildings of the Regional Centre of the German Weather Service and the Federal Maritime and Hydrographic Agency are located in the course of the road to the east.

Lake Ouescapis is a freshwater body of the Broadback River watershed in the Municipality of Eeyou Istchee Baie-James (municipality), in the Administrative Region of Nord-du-Québec, in Quebec, in Canada. Forestry is the main economic activity of the sector. Recreational tourism activities come second. The hydrographic slope of Lake Ouescapis is accessible via the James Bay road (North-South direction) from Matagami, passing from the West of the lake.

A pile of whale bones in Point Hope, at the spot where celebrations are held at the conclusion of the whaling season. Before any modern settlement, the Ipiutak lived here. The descriptive Inuit name of the place, "Tikarakh" or "Tikiġaq", commonly spelled "Tiagara", means "forefinger". It was recorded as "Tiekagagmiut" in 1861 by P. Tikhmeniev Wich of the Russian Hydrographic Department and on Russian Chart 1495 it became "Tiekaga".

The ships were designed to be capable of surveys supporting hydrographic and bathymetric charting and oceanographic requirements. They differed chiefly in installed equipment and systems, particularly data acquisition systems. The initial Bent installation was a prototype "Shipboard Survey System" based on a standard Navy AN/UYK computer. Later Bent was equipped with the Oceanographic Data Acquisition System (ODAS), operational 1971, as were the later oceanographic survey ships Kane and Wilkes.

Amadi Ikwechegh was born on 25 February 1951 in Amakpo, Igbere in Bende, Abia State. He attended Township School in Aba and the Nigerian Military School, Zaria (1963 to 1966), and attended the Nigerian Defence Academy, Kaduna in 1971. He was commissioned as a sub-lieutenant in 1974. He then studied at Britannia Royal Naval College at Dartmouth, England, the Royal Hydrographic School, Australia and the Naval School of Oceanography, USA.

The atolls and islands of the Gilbert Islands are arranged in an approximate north-to- south line. As the crow flies it is approximately between the northernmost island, Makin, and the southernmost, Arorae. In a geographical sense, the equator serves as the dividing line between the northern Gilbert Islands and the southern Gilbert Islands. However, the International Hydrographic Organization (IHO) considers the Gilberts wholly within the South Pacific Ocean.

Humacao's hydrographic system consists of many rivers and creeks like Humacao, Antón Ruíz, and Candelero. Some of its creeks are Frontera, Mariana, and Del Obispo, among many others. In 2019, updated flood zone maps show that Humacao is extremely vulnerable to flooding, along with Toa Baja, Rincón, Barceloneta, and Corozal. Located where most cyclones enter the island, Humacao is one of the most vulnerable areas of Puerto Rico.

The expedition departed Toulon on 10 August 1822, making for South America. After stopping at Brazil and the Falkland Islands, the French rounded Cape Horn on 31 December 1822 and travelled along the coast to Peru, conducting hydrographic surveys. They reached Tahiti in May 1823, anchoring at Matavai Bay where Blosseville started his hydrographical surveying work. While at Tahiti, Blosseville became acquainted with Captain John Dibbs of the colonial barque Endeavour.

In July 1931 Soutter signed on to be a crew member on the maiden sail of the Atlantis, Woods Hole Oceanographic Institution's first research vessel. Doctor Henry Bryant Bigelow, the first director of the Woods Hole Oceanographic Institution and professor of zoology at Harvard (and later, Soutter's father-in-law) received funding from the Rockefeller Foundation to build this vessel and to embark upon oceanographic and hydrographic investigations.

Tucker resigned from the Peruvian Navy in 1871. He was then appointed president of the Hydrographic Commission of Peru on the Amazon River, which included a group of American and Peruvian naval officers and engineers, James Henry Rochelle, David Porter McCorkle, Walter Raleigh Butt, and Thomas Wing Sparrow, among others.Clayton, Lawrence A. Peru and the United States: The Condor and the Eagle. Athens: University of Georgia Press, 1999, p. 39–40.

The expedition surveyed the upper Amazon River and its tributaries and discovered two new rivers, the Trinidad and the Herrera-yacu. Tucker traveled to New York upon completion of the expedition to have maps and atlases made and the Commission's findings published.J. H. Rochelle and T. R. Tucker. Report of the Hydrographic Commission of Peru on the Amazon River, Journal of the American Geographical Society of New York, Vol.

The Baumberge are the highest hills in the natural regions of Münsterland and Kernmünsterland with a maximum height of .In the historic Münsterland the Westerbecker Berg at in Tecklenburger Land and in the natural region of the Teutoburg Forest was the highest elevation. They are located between Münster and Coesfeld, which is itself close to the southwest edge of the Baumberge. The hilly terrain has several geological, hydrographic and architectural features.

Snowden was born in Peekskill, New York. He was appointed a Cadet Midshipman on June 25, 1875, and graduated from the U.S. Naval Academy in 1879. He served in USS Vandalia (1876), USS Standish (1864), USS Monongahela (1862), USS Dolphin (PG-24), and USS Constellation (1854). Snowden was assigned to the Hydrographic Office, U.S. Naval Observatory, U.S. Naval Academy, Naval War College, and the Office of Naval Intelligence.

The International Hydrographic Organization defines the limits of the Gulf of Alaska as follows: > On the North. The coast of Alaska. On the South. A line drawn from Cape > Spencer, the Northern limit of the Coastal Waters of Southeast Alaska and > British Columbia to Kabuch Point, the Southeast limit of the Bering Sea, in > such a way that all the adjacent islands are included in the Gulf of Alaska.

Similarly the President (Modified Type 12) class frigates , and were also converted to carry a single Wasp helicopter to be used in an anti-submarine or survey role. The hydrographic survey vessel and fleet replenishment vessel carried the Wasp helicopter in similar fashion. Of the sixteen helicopters delivered, six were lost in service. One particular Wasp that ditched at sea off Milnerton was salvaged and rebuilt to fly again.

Maps published by Mary Ann Rocque are in many libraries and archives, including the National Archives, the Massachusetts Historical Society, the United States Military Academy, the University of Virginia, the British Library, and the UK Hydrographic Office.John Rocque, A set of plans and forts in America. London: Mary Ann Rocque, 1765; Tracy W. McGregor Library, University of Virginia. Some of Rocque's maps were published under the name M. A. Rocque.

To the south-west is the Great Himalayan Range which separates Zanskar from the Kisthwar and Chamba basins. To the north-east lies the Zanskar Range, which separates Zanskar from Ladakh. The only outlet for the whole Zanskar hydrographic system is thus the Zanskar river, which cuts the deep and narrow Zanskar Gorge through the Zanskar range. These topographical features explain why access to Zanskar is difficult from all sides.

Delaware II after a drydock mishap.Delaware IIs deck equipment features five winches, one boom crane, two A-frames, and a movable gantry. This equipment gives Delaware II a lifting capacity of up to 7,000 pounds (3,170 kilograms) as well 19,680 feet (6,000 metres) of cable that can pull up to 20,000 pounds (9,070 kilograms). Each of the winches serves a specialized function ranging from trawling to hydrographic surveys.

This equipment gave Rude a lifting capacity of up to 7,500 pounds (3,400 kg). It also had 500 feet (152 meters) of cable that could pull up to 250 pounds (113 kg). For its primary mission of inshore hydrographic surveys, Rude had a differential global positioning system (DGPS), a multibeam sonar system, and side-scan sonar (SSS). It also was equipped for diving operations to allow human investigation of submerged obstacles.

Holmes Island () is an island long, lying south of Vieugue Island in the Biscoe Islands of Antarctica. It was charted by the British Graham Land Expedition under John Rymill, 1934–37, and was named by the UK Antarctic Place-Names Committee for Bryan Holmes, a Falkland Islands Dependencies Survey surveyor at Prospect Point in 1957, who was attached to the British Naval Hydrographic Survey Unit in this area, 1957–58.

Lurker Rock is a rock high, located northeast of Dismal Island, Faure Islands, in Marguerite Bay, Antarctica. It was charted by the Hydrographic Survey Unit from RRS John Biscoe in 1966. The name, applied by the UK Antarctic Place- Names Committee in 1971, is descriptive of the feature, which is covered by ice and can easily be mistaken for a piece of floating ice, especially at high water.

They are connected with the main orographic and hydrographic junction of the mountain, Kanarata peak (2691 m), through which passes the watershed between the Black Sea and Aegean Sea catchment areas. The glacial relief is typical for the highest zone of the park and dates from the Pleistocene. During the glacial periods the limits of the permanent snow cover were at 2200 m. The glaciers melted down 10–12000 years ago.

Map showing the Togian Islands highlighted in the Gulf of Tomini. The International Hydrographic Organization (IHO) defines the Gulf of Tomini as being one of the divisions of the East Indian Archipelago. It is defined as the waters west of the "Western limit of the Molukka Sea", which is elsewhere defined as the line running from "Tg. Pasir Pandjang ()... across to Tg. Tombalilatoe (123° 21′ E) on the opposite coast".

It is characterized by Quaternary age and modern terrain with swampy surface, coastal-marine sediments, subtropical climate, tight hydrographic network, wetlands, mesophilic and hydrophilic vegetation development. The surface, especially in its seaside part, is characterized by intense moisture. Odishi-Guria plain is crossed by Enguri, Khobi, Rioni, Tekhuri and Abasha rivers. It also has many local streams that entirely run within the plain: Tikori, , Tsia, Tsivi, and Pichori rivers.

It has authority over geographical and hydrographic names within New Zealand and its territorial waters. This includes naming small urban settlements, localities, mountains, lakes, rivers, waterfalls, harbours and natural features and may include researching local Māori names. In the Ross Sea region of Antarctica it has named many geographical features. It has no authority to alter street names, a local body responsibility, or the name of any country.

With four civilian geophysicists on board from the Hydrographic Office, the submarine completed a submerged survey of Eniwetok, Wake, and Midway Island, operating at sea for nearly three months. She returned to San Diego, California, on December 5, 1958 for inactivation. Tilefish was decommissioned on October 12, 1959, underwent overhaul at the San Francisco Naval Shipyard, and was recommissioned on January 30, 1960. Her final decommissioning was in May 1960.

It is covered with drifting ice all year round. The strait was discovered in 1913 by a Russian hydrographic expedition led by Boris Vilkitsky and then named after him in 1918. The Geiberg Islands cover the entrance to the Vilkitsky Strait from the east, and the Firnley Islands do so from the west. The shores on the side of the Taymyr Peninsula are covered with tundra vegetation and scattered stones.

In May 1806, his contract expired. He and Ravenet presented all of their works to Count , Director of the Hydrographic Office. Two years later, following the Siege of Zaragoza, he and his fellow artist Juan Gálvez went there by invitation of General José de Palafox to create a graphic record of the event's aftermath. Thirty-two of these drawings were later published as Grabados de la Ruina de Zaragoza.

The Aitcho Islands (‘Aitcho’ standing for ‘H.O.’ i.e. ‘Hydrographic Office’) are a group of minor islands on the west side of the north entrance to English Strait separating Greenwich Island and Robert Island in the South Shetland Islands, Antarctica, which are situated between Dee Island to the south and Table Island to the north. The group is separated from Dee Island and Sierra Island to the southwest by Villalón Passage ().

A tropical depression formed within a monsoon trough on March 23, 2019, off the coast of Bahia. On the next day, the system intensified into a tropical storm, receiving the name Iba from the Brazilian Navy Hydrographic Center. Iba was the first tropical storm to develop in the basin since Anita in 2010, as well as the first fully tropical system to be named from the Brazilian naming list.

The International Hydrographic Organization's definition of the limits of the Seto Inland Sea (published in 1953) is as follows: > On the West. The southeastern limit of the Japan Sea [In Shimonoseki-kaikyo. > A line running from Nagoya Saki (130°49'E) in Kyûsû through the islands of > Uma Sima and Muture Simia (33°58',5N) to Murasaki Hana (34°01'N) in Honsyû]. > On the East (Kii Suidô).

It might have been that these surrounding hydrographic systems served defensive functions as naturally existing barriers. The Pocora Causeways does not communicate directly with another archaeological site, but is aiming towards Williamsburg (L-58Wb) 3.5 km to the southeast of Las Mercedes-1. While the causeway ends 1.5 km before reaching Williamsburg, a footpath has been archaeologically identified that may extend the rest of the way connecting these sites.

Between 1931 and 1938, Binyon taught part-time at the Eastbourne College of Art and also at the North London Collegiate School. With her twin sister, Margaret, Binyon established a travelling puppet theatre, Jiminy Puppets. During 1938 she worked for Robert Gibbings producing illustrations for the Penguin Illustrated Classics series, including an edition of Pride and Prejudice. During World War II, Binyon worked for the Admiralty drawing hydrographic charts.

The Vaupés Arch is a hydrographic feature in the geology of Colombia. The Vaupés Arch forms the major drainage divide in the southern extent of the Llanos region of eastern Colombia and the western slopes of the Guiana Shield in Venezuela.Kirk O. Winemiller and Stuart C. Willis, "The Vaupés Arch and Casiquiare Canal" in James S. Albert and Roberto E. Reis, eds. Historical Biogeography of Neotropical Freshwater Fishes, 2011:225-242.

In 1916 he published Intereses argentinos en el mar [Argentine Interests in the Sea], an important reference work on defense and maritime interests, based on his lecture delivered in 1916. Other published works were: Hydrographic works and Argentine limit in the Beagle Channel (1905); Ballistics and explosives for the navy (1908); Project of the regime of the territorial sea (1911) and The territorial sea (1926); and Geostrategy Manual .

At some points the hydrographic equipment aboard Tautog registered zero distance between the submarines. At another point "Tautog's" hydrophone operators assumed the K-108 had risen to near the surface, placing the Soviet submarine directly above Tautog. Then the operators determined the Soviet vessel was descending. The trace on the oscilloscope, that gave the American submariners at visual reference as to the distance of the K-108, disappeared.

The Quest-class oceanographic research vessel was designed for oceanographic and hydrographic research for the Royal Canadian Navy. The ship displaced and was long overall with a beam of and a draught of . The ship was fitted with a small helicopter platform capable of handling light helicopters but this was later removed and converted to a rear crane platform. Quest was a diesel electric, twin shaft, twin rudder ship.

The Drin river and Vau i Dejës Lake The hydrographic network is represented by an artificial lake (Vau i Dejës Lake), Drin River and several streams, the most important being the Gomsiqe brook and the Zazlli brook. All these flow from the mountain of Gomsiqe. Vau i Dejës Lake has an area of 26 km², while the water surface is 25 km². Its depth ranges up to 50m.

Day (1967), pp. 128–129 & 187. In 1902 Lieutenant and Commander Ernest Clifford Hardy was in command, and she was in Hong Kong in October that year. Socotra Rock was surveyed by Waterwitch confirming a depth of less than ,United Kingdom Hydrographic Office – Survey number B7973 (Eh) "Socotra Rock, Found by HMS Waterwitch, August 1901" and she met severe gales in the Formosa Channel in 1903, and lost three men overboard.

The ship's function was to transport, deploy, retrieve and repair submarine cables and test underwater sound devices, with a secondary mission of conducting acoustic, hydrographic, and bathymetric surveys."MSC Fact Sheet: Cable Repair Ship - T-ARC", Military Sealift Command. Accessed 2010-05-16. Zeus is equipped with a SIMRAD EM 121 sonar, and can also operate towed sidescan sonars and deploy data buoys to assist in oceanographic surveys.

Some multibeam echosounders such as the Teledyne Odom MB2 also incorporate a motion sensor at the face of the acoustic transducer, allowing even faster installation on small vessels. Multibeam echosounders like this are allowing many smaller hydrographic survey companies to move from traditional single beam echosounders to swath systems. Multibeam data includes bathymetry, acoustic backscatter, and water column data. Gas plumes now commonly identified in midwater multibeam data are termed flares.

Jesse Barrett Oldendorf was born in Riverside, California on 16 February 1887. He graduated from the United States Naval Academy in 1909, standing 141st in a class of 174, and was commissioned in 1911. Oldendorf served aboard the armored cruiser , the torpedo boat destroyer , the cruiser , the destroyer and the armored cruiser California again, although she had been renamed San Diego. He also served on the Panama Canal hydrographic survey ship .

The ship was built in 1970 by Stocznia Polnocna, Gdańsk as a hydrographic survey vessel and converted to military use in 1989. It was outfitted for signals intelligence (SIGINT) purposes. It initially served with the Northern Fleet and was transferred to the Black Sea Fleet in 1974. In April 1999, Liman was deployed in the Adriatic Sea at the request of Yugoslav president Slobodan Milošević to monitor NATO operations against Yugoslavia.

The species name "susaguae" is taken from the Susaguá River in which hydrographic basin the frog has been found. Susaguá is Chibcha, the language spoken by the Muisca who inhabited the area where the toad has been found; the Reserve Forest of Zipaquirá and Cogua, Colombia. It has an altitudinal range of to above sea level, and it might occur more widely than is currently known.Rueda, J.V. 2004.

Cape Lutkes headland Cape Lutke is a headland on Unimak Island, the largest island in the Aleutian Islands chain of the U.S. state of Alaska. It is located on the southern central coast of the island. This headland was named Mys Litke, after Russian explorer Count Fyodor Petrovich Litke, by the Imperial Russian Hydrographic Service in 1847. "Litke" is the Russian form of the German "Lütke", which is Anglicized as "Lutke".

After his retirement, Admiral Crosley was elected president director of the International Hydrographic Bureau at Monte Carlo, Monaco, in April 1937, and served in that capacity until his resignation in June 1938 on account of ill health. He died on January 6, 1939, at Johns Hopkins University Hospital, Baltimore, Maryland, and was buried at Arlington National Cemetery. Admiral Crosley was a member of the Sons of the American Revolution.

The hydrographic network contains a large drainage basin, namely the Oued-Soummam basin. The town of El kseur is supplied with water by the dam of Tichy-haf located in the locality of Bouhamza. The dam is fed by the rain and melt water of the Djurdjura's nival coat. It has a storage capacity of 150 million m3 and supplies the wilaya of Béjaïa with 20,000 m3 / day.

The modern Thai name of the gulf is Ao Thai (, , "Thai Gulf") and "Gulf of Thailand" has been adopted as the official name of the body by the International Hydrographic Organization. Its name in Malay and Khmer continues to be the "Gulf of Siam", Teluk Siam and , Chhoung Samut Siem, respectively. In Thai, the gulf is historically known as Ao Sayam (). In Vietnamese it is known as Vịnh Thái Lan.

In 1948, Fort Frances was transferred to the Department of Mines and Technical Surveys for use as a hydrographic ship. In 1958 she was converted into an oceanographic survey ship. Three laboratories were installed along with the ability to carry up to eight scientists, her main purpose being underwater acoustic research. Fort Frances served in this duty until she was sold in 1974 for scrap and broken up.

Thus became the metric length for a nautical mile. France made it legal for the French Navy in 1906, and many metric countries voted to sanction it for international use at the 1929 International Hydrographic Conference. Both the United States and the United Kingdom used an average arcminute, specifically, a minute of arc of a great circle of a sphere having the same surface area as the Clarke 1866 ellipsoid.

Arriving Bikini Atoll 16 March, for the next 5 months she operated between Bikini and Eniwetok while conducting hydrographic, oceanographic, and other scientific surveys. Reclassified AGSC-13 on 29 July, James M. Gilliss departed Bikini 19 August. Steaming via Pearl Harbor, she reached San Francisco, California, 30 September. Assigned to duty with the U.S. Atlantic Fleet, she departed San Francisco 23 November and arrived Norfolk, Virginia, 23 December.

For the most part, the Philippine Islands constituted her sphere of operations. She conducted patrols, carried passengers and mail among the islands, and supported the Army during the first stage of the Philippine–American War. She also participated extensively in the hydrographic surveys made of the islands. In the summer and fall of 1903, she joined American's Far Eastern fleet for a cruise to Chinese and Japanese waters.

Bathymetric surveys are a subset of the science of hydrography. They differ slightly from the surveys required to create the product of hydrography in its more limited application and as conducted by the national and international agencies tasked with producing charts and publications for safe navigation. That chart product is more accurately termed a navigation or hydrographic chart with a strong bias toward the presentation of essential safety information.

By 1930 the Department of Terrestrial Magnetism had enough data to be able to produce a much better view of Earth's magnetic field than had previously been available. The loss of Carnegie left a void in capability to collect oceanic magnetic data. By 1951 world magnetic charts were badly flawed. As a result the U.S. Navy Hydrographic Office initiated Project Magnet, an airborne program to collect magnetic data world wide.

On the return voyage to home port, the ship saw short duty as Station Ship Hong Kong. While in Hong Kong, Princess Margaret was piped aboard the ship. The MiG-17 flown by Nguyen Van Bay B in the attack on Higbee, 19 April 1972. Higbee under repair at Subic bay following her bomb hit While operating northeast of Luzon in late January 1966, Higbee sighted the Soviet hydrographic ship Gidrifon.

He was promoted to the rank of commander in 1877. From November 1878 until 1882, he commanded the oceanographic survey ship George S. Blake of the US Coast and Geodetic Survey, where he discovered, between Jamaica and Cuba, the Bartlett Deep. Other accomplishments while commanding the Blake included working with biologist Alexander Emanuel Agassiz and studying the Gulf Stream. From 1882 until 1888 he was in charge of the Hydrographic Office.

In 1876, Ivens set out for the United States, bringing Portuguese products to Philadelphia for the Centennial Exposition. His ancestor, Thomas Hickling, had been an ardent American revolutionary, and had in fact left Boston for the Azores following an argument with his loyalist father. Ivens went on an expedition into the provinces of Angola and Mozambique beginning on May 11, 1877 and studied relations between hydrographic basins in Zambezi.

The company had to find a new customer also for the diesel-powered ship ordered by Russian Hydrographic Office; she became eventually a part of the Finnish merchant ship fleet and sailed under name Sunkist. Manager Adolf Engström left his position in 1919. He was replaced by Walter K. Åström. In the same year the company was sold to a consortium and subsequently almost all board members were changed.

Thanks to the frequent rains and high humidity, Gorgona has a rich hydrographic system that includes a large amount of water currents flowing towards the ocean. Most of these are located on the eastern side of the island. Around 25 streams remain active all year round and 75 during the rainy season. In less than half a kilometer on the beach called La Camaronera ten creeks reach the sand.

Trujillo Alto's hydrographic system consists mainly of the Río Grande de Loíza (river), which crosses the municipality. There are also several creeks in the city: Colorada, Infierno, Limones, Naranjo, Grande, Pastrana, Haya Fría, and Maracuto. Also, Trujillo Alto is the site of Puerto Rico's main water reservoir: The Carraízo Dam, at the Loíza Lake. Both were built in 1953 by the Puerto Rico Aqueducts and Sewers Authority (PRASA).

South East Point is a point east-north-east of Fildes Point, marking the south-eastern point of Deception Island, in the South Shetland Islands of Antarctica. It was charted by a British expedition 1828–31, under Henry Foster. The name was proposed in 1949 by the Hydrographic Department of the Admiralty, following a survey of the island by Lieutenant Commander D.N. Penfold, Royal Navy, in 1948–49.

In 1813 Barrie collected runaway slaves from the Maryland and Virginia shores. After a brief period spent living in France Barrie took up the post of Acting Commissioner of the Quebec Dockyard 1817-1818. By 1819, he served as Commissioner of the dockyard at Kingston. He was active in a number of areas, building and expanding the dockyard and promoting important hydrographic surveys and the construction of canals.

Her hydrographic work in the Gulf of Siam was continued into December. In January 1963, she readied her drafting room and laboratory for oceanographic work to be conducted in the Andaman Sea and Bay of Bengal during February and March. In April, she rejoined Maury in the Gulf of Siam and, in May, headed back to Pearl Harbor. Serrano remained in Hawaiian waters from 10 June to 18 October.

The International Hydrographic Organization defines the limits of the Singapore Strait as follows: > On the West. The Eastern limit of Malacca Strait [A line joining Tanjong > Piai (Bulus), the Southern extremity of the Malay Peninsula () and The > Brothers () and thence to Klein Karimoen ()]. On the East. A line joining > Tanjong Datok, the Southeast point of Johore () through Horsburgh Reef to > Pulo Koko, the Northeastern extreme of Bintan Island ().

By 1887, he was a second lieutenant, and participated in the hydrographic reconnaissance of the north of Chile, specially the areas of Esmeralda, Carrizal Bajo, and Arica. During his career, he served in almost all the ships of the Chilean Fleet. During the 1891 Chilean Civil War, he fought for the congressional side against President José Manuel Balmaceda. After the war, he rose thought the ranks very quickly.

The International Hydrographic Organization defines the Philippine Sea as "that area of the North Pacific Ocean off the Eastern coasts of the Philippine Islands", bounded as follows: > On the west. By the eastern limits of the East Indian Archipelago, South > China Sea and East China Sea. On the north. By the southeast coast of > Kyushu, the southern and eastern limits of the Inland Sea and the south > coast of Honshu Island.

Farquharson was connected to the European scientific elite. He corresponded with Leibniz and the Royal Society about Russia as well as scientific topics. He believed to have translated as many as 38 scientific works into Russian including Euclid's Elements and Henry Brigg's Arithmetic logarithmica. Farquharson was also a talented cartographer, producing a bronze engraving of Mercator's map of America and led the creation of a hydrographic atlas of the Caspian Sea.

Over a period of over 20 years, he wrote a book entitled Sailing directions for the Gulf and River of St. Lawrence, that was published in instalments. It was later republished in 1860 as The St. Lawrence pilot. Several ships which served in the Canadian Hydrographic Service or its predecessors have been named in his honour. He died in Charlottetown on 10 February 1885, at the age of 90.

Sergey Kravkov's name is borne by one of the biggest of the Mona Islands in the Kara Sea. This name was given to the island in 1933 by the Soviet hydrographer Vsevolod Vorobyev who first measured its exact position. In 1974 a hydrographic vessel ordered by the USSR was launched in Finland. Named Sergey Kravkov, it is currently owned by the Russian Ministry of Transport's Federal State Unitary Enterprise Gidrograficheskoye predpriyatiye.

Potmess Rocks is a group of large rocks lying northwest of Robert Island in the South Shetland Islands, Antarctica. The group is extending , featuring the conspicuous rocks named Asses Ears in the north. The area was visited by early 19th century sealers operating from nearby Clothier Harbour. The feature's name derived from the midday stew served on the launch Nimrod during the Royal Navy hydrographic survey of the rocks in 1967.

Bowler Rocks is a group of rocks off the north coast of Greenwich Island in the South Shetland Islands, Antarctica lying southwest of Table Island and northwest of Aitcho Islands, and extending in east-west direction. The area was visited by early 19th-century sealers. The feature is named after David Bowler, surveying recorder aboard the launch Nimrod during the Royal Navy hydrographic survey of the rocks in 1967.

In 1994, the Canadian hydrographers Rob Hare and Peter Kielland were in Monaco for the International Hydrographic Organization; the pair went to the bar to check that graffiti left by Canadian hydrographers was still there. Lighthouse, the journal of the Canadian Hydrographers' Association, described Rosie's bar as a "real hydrographers bar". In 1969, the location of the bar was moved by as a result of redevelopment. The bar closed in 1996.

The name Cape Carnot honours Lazare Carnot who is notable as a "French mathematician, general and statesman, who played a prominent part in the French Revolution and the Napoleonic era". The cape is considered by the Australian Hydrographic Service to be the eastern end of the Great Australian Bight. Since 2012, the waters adjoining its shoreline are within a habitat protection zone in the Thorny Passage Marine Park.

In 1841, Shestakov returned to Sevastopol and participated in several battles against mountaineers. Ivan Shestakov was awarded with an Order of St. Stanislaus of 3rd degree. On April 11, 1843 (Old Style) Admiral Mikhail Lazarev made him his aide-de-camp for two years and promoted him to the rank of lieutenant. In 1847–1850, he finished the hydrographic studies of the Black Sea on board the cutter Skory.

On February 14, 2018, Locsin tweeted that criticizers of the Chinese names imposed by China on the Philippine Rise, which have been recognized by the International Hydrographic Organization, are 'childish and stupid', sparking a word war on the issue. Criticizers noted that Locsin is the current ambassador to the United Nations and should be one the first to defend the Philippines' sovereignty and sovereign rights. Locsin did not reply afterwards.

Portrait of Captain Henry Roberts by Thomas Gainsborough. Henry Roberts (1756–1796) was an officer in the Royal Navy who served with Captain Cook on his last two voyages. Roberts served as lieutenant on Cook's HMS Discovery, where he was entrusted with many hydrographic and cartographic tasks, and also met then-midshipman George Vancouver. Roberts spent many years after that voyage preparing the detailed charts that went into Cook's posthumous Atlas.

Archerfish was reactivated at New London in July 1957, placed back in commission on 1 August, and again joined SubRon 12 at Key West. On 13 January 1958, she got underway for a cruise under the technical supervision of the Navy Hydrographic Office. On this deployment, she visited Recife, Brazil, and Trinidad. Upon completion of that mission she provided services for the fleet training commands at Key West and Guantanamo Bay.

Protea is a specialist hydrographic survey vessel, although its equipment has been used in search and rescue operations using Proteas shallow water route survey system (SWRSS). She is the only ship in the South African Navy that is painted white, denoting that she is not a warship. Her hull is strengthened for navigation in ice and she is fitted with a transverse bow thruster unit, for increased manoeuvrability in harbour.

The International Hydrographic Organization, the international governing body for the naming bodies of water around the world, in 2012 recognized the term "Sea of Japan" as the only title for the sea.Kyodo News, "IHO nixes 'East Sea' name bid", Japan Times, 28 April 2012, p. 2; Rabiroff, Jon, and Yoo Kyong Chang, "Agency rejects South Korea's request to rename Sea of Japan", Stars and Stripes, 28 April 2012, p. 5.

Investigator primary tasks are hydrographic survey, nautical chart preparation, cartography and training, and it is equipped with a remotely operated underwater vehicle (ROV), an autonomous underwater vehicle (AUV) and an unmanned surface vehicle (USV). In early 2008, the ship conducted a hydrographic survey in Seychelles in cooperation with the Seychelles Coast Guard (SCG) and the Seychelles People's Defence Force (SPDF). The survey covered the entire coast, from North Point to Petite Anse, replacing navigational charts made in 1890. Investigator conducted survey work in and around western Mahe that year (to facilitate the preparation of a new navigational chart that year), In the same year, Investigator also conducted survey work in Mauritius, and surveyed 30 percent of the St. Brandon shoals (part of the Outer Islands of Mauritius) to update charts first prepared in 1851 and create a profile for a Mauritius Oceanography Institute–Commission on the Limits of the Continental Shelf survey.

These projects included ground surveys, definition of geodetic datums, air photography, assistance with definition of Exclusive Economic Zones, mapping, provision of equipment and technology transfer and training of officers and technicians. Projects commenced in 1970 in Indonesia and expanded over 25 years to include Solomon Islands, Fiji, Tonga, Kiribati, Nauru, Tuvalu, Vanuatu and Western Samoa. Technical Advisers were posted to national survey and mapping organisations in Fiji, Indonesia, Malaysia, Papua New Guinea, Solomon Islands and Vanuatu. All field survey operations outside of Australia, and indeed in Australia, would not have been possible without essential support of most other Army Corps (Engineers; Signals; Aviation – Cessna, Porter, Nomad, Sioux, Kiowa; Chaplains, Medical, Dental, Transport, Ordnance, Electrical and Mechanical Engineers, Pay, Catering, Service), the Royal Australian Navy (Hydrographic Service, Landing Craft, Patrol Boats) and at times the Royal New Zealand Navy (Hydrographic Service), the Royal Australian Air Force (Canberra, Hercules, Caribou, Iroquois) and civil charter fixed wing and helicopters for aerial survey work and transport.

The history of hydrographic surveying dates almost as far back as that of sailing. For many centuries, a hydrographic survey required the use of lead lines – ropes or lines with depth markings attached to lead weights to make one end sink to the bottom when lowered over the side of a ship or boat – and sounding poles, which were poles with depth markings which could be thrust over the side until they touched bottom. In either case, the depths measured had to be read manually and recorded, as did the position of each measurement with regard to mapped reference points as determined by three-point sextant fixes. The process was labor-intensive and time-consuming and, although each individual depth measurement could be accurate, even a thorough survey as a practical matter could include only a limited number of sounding measurements relative to the area being surveyed, inevitably leaving gaps in coverage between single soundings.

Officers of Abtao during the War of the Pacific Abtao was commissioned on 1 June 1867, after the Chinchas war, under the command of Capitán de Fragata Enrique Simpson Baeza later was she under command of Galvarino Riveros Cárdenas and 1868 she brought help to Arica after the 1868 Arica earthquake. Under Capitan de Corbeta Francisco Rondizzoni de la Cotera she made a hydrographic survey of the Chilean coast between Mataquito River and the Tumán Bay. On 12 February 1873 she was put under the command of Capitán de Corbeta Jorge Montt Alvarez and she sail to the Strait of Magellan to a hydrographic survey as she did up 1876 between the Parallel 23°S and the Caleta del Cobre. According to Oscar Bermudez Miral, the corvette Abtao set sail under the command of Commander F. Rondizzoni, member of the Northern Atacama Coastal Exploration Committee, tasked with making studies as proposed by Minister Victorio Lastarria.

The Laptev Sea shore of present-day Severnaya Zemlya was discovered by Boris Vilkitsky in 1913 during the Arctic Ocean Hydrographic Expedition on behalf of the Russian Hydrographic Service, but he was unaware that there was a strait west of the cape between what is now Bolshevik Island and the islands further north, for the straits are frozen most of the year, forming a compact whole."Октябрьской Революции Остров" Great Soviet Encyclopedia This cape was named during the 1930–1932 expedition to the archipelago led by Georgy Ushakov and Nikolay Urvantsev after Soviet scientist Fedor Baranov (1886–1965).Архипелаг Северная Земля — один из наиболее крупных районов оледенения на территории России Located near Cape Baranov, roughly to the SSE of the cape,Информационное сообщение об открытии «Ледовой базы «Мыс Баранова» для выполнения научных работ ААНИИ в 2013–2014 г.г. the Prima Polar Station of the Arctic and Antarctic Research Institute closed down in 1996 and reopened in June 2013 as a private venture.

Dixey Rock () is a rock rising above sea level, southeast of Darwin Island in the Danger Islands. It was mapped by the Falkland Islands Dependencies Survey in 1953–54 and 1956–58, and photographed from the air by the Falkland Islands and Dependencies Aerial Survey Expedition, 1956–57. It was named by the UK Antarctic Place-Names Committee in 1980 after David J. Dixey, Head of Nautical Branch 5 at the Hydrographic Department.

He saw naval service in the East and West Indies as well as in European waters. In the Royal Netherlands Navy, he was a hydrographic specialist. From about 1920, he began to be interested in naval history and began with a special interest in the three Anglo-Dutch wars (1652-1674). He retired from active service in 1932 and devoted the remainder of his life to the study of Dutch maritime history.

The hydrographic slope of Muscocho Lake is accessible via the R1040 forest road (going North-South) to the east of the lake and connecting to the north at route 113 (linking Lebel-sur-Quévillon and Chibougamau) and the Canadian National Railway. Haüy Township is located north of the lake. The surface of Muscocho Lake is usually frozen from early November to mid-May, however safe ice movement is generally from mid-November to mid-April.

Spume Island is a small, low, rocky island lying southwest of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago of Antarctica. It is located at . Spume Island was surveyed by the British Naval Hydrographic Survey Unit, 1956–1957. Spume Island was named by the United Kingdom Antarctic Place-names Committee (UK-APC) because heavy seas break over the island in a gale; spume is blown over it.

Mount Gale () is a promontory at the north end of Frecker Ridge in the Anare Mountains of Victoria Land, Antarctica. This topographical feature stands at the south side of the confluence of Ludvig Glacier and Kirkby Glacier. It was named by the Antarctic Names Committee of Australia for Commander d'A.T. Gale, formerly of the Royal Australian Navy, a hydrographic surveyor with the Australian National Antarctic Research Expeditions (Thala Dan) cruise that explored this coast, 1962.

Africa Pilot: The southwest coast of Africa from Cape Palmas to the Cape of Good Hope, including the islands of St. Helena, Ascension, Tristan da Cunha, and neighboring islands, United States Hydrographic Office, 1916, pp. 420-421Proceedings of the Royal Geographical Society and Monthly Record of Geography, Volume 5, Edward Stanford, 1883, p. 458. Work to desilt the river and reinforce its banks near the river mouth was done in the 2000s for flood control.

Recreational tourism activities come second. The western portion of the Buade Lake hydrographic slope is accessible via the R1032 forest road (North-South direction) which passes through the Ventadour River valley, on the west side. The forest road route 167 passes northeast of Nicabau Lake, connecting Chibougamau to Saint-Félicien, Quebec; a secondary road is detached to serve the east side of Poutrincourt Lake. The Canadian National Railway runs along route 167.

The name Urn Island was mentioned in Asiatic Pilot by the U.S. Hydrographic Office in 1910. The book described that vessels can enter Rocky Harbour from Port Shelter by passing through water passage near islets Urn Island (Tai Tau Chau) and Yim Tin Tsai. The book recommands to use sea chart as a guide, as the channel is narrow. Since the 1980s, some part of the island became an approval burial site for fishermen.

Allegheny transited from Norfolk to the New York Naval Shipyard arriving on 14 June 1952 for conversion into a research vessel. During the summer of 1952 all armament and towing accessories were removed with the towing winch rotated 90° and modified for over the side operations. Various hydrographic and bathythermograph winches and booms were installed as was sonar and various electronic equipment. Shipboard spaces were converted to a machine shop, motor generator, and photographic laboratory.

The Navy's operational headquarters, Fleet Headquarters, is located adjacent to Fleet Base East. The majority of the Navy's patrol boats are based at in Darwin, Northern Territory, with the remaining patrol boats and the hydrographic fleet located at in Cairns. The Fleet Air Arm is based at near Nowra, New South Wales. The Australian Army's regular units are concentrated in a few bases, most of which are located in Australia's northern states.

At roughly , it is one of the longest rivers in Uruguay. It forms in Cuchilla Grande, then joins the Rio Olimar Grande and flows into the Merin Lagoon in Treinta y Tres. In October 2009 the National Hydrographic Institute of Uruguay started operating a free raft service across the Cebollatí River; this service allows commuters to cross from Treinta y Tres to Rocha in a wooden raft between the localities of Cebollatí and Charqueada.

HMAS Basilisk is a former Royal Australian Navy (RAN) shore naval base, located in Port Moresby, Papua New Guinea. The first RAN naval base in Papua New Guinea, the base was commissioned on 1 January 1943 under the command of Commander R.B.A. Hunt RAN, who was previously the Naval Officer in Charge Port Moresby. Hunt was the hydrographic surveyor who had surveyed Port Moresby. Basilisk was paid off on 17 December 1945.

Construction work at alpha ventus wind park (July 2009) The application for construction of the wind farm near Borkum was submitted in 1999. The permit was given by the Federal Maritime and Hydrographic Agency in 2001. In 2007, contracts for supplying wind turbines were signed with REpower and Multibrid (later: Areva Wind and Adwen). That same year, a contract for the construction of a subsea cable connection to the German grid was signed.

The Arctic Ocean Hydrographic Expedition 1910–1915 From 1915 during World War I, Novopashenny commanded the modern Novik class destroyer Desna (Russian: Десна). In 1916 he became commander of the destroyer "Constantine" (Russian: Константин). For his services before and during the war, he was awarded the Imperial Russian Order of Saint Anna (Russian: Орденъ Святой Анны) for service (4th stage on 5 May 1904, 3rd stage on 12 August 1907, 2nd stage 12 November 1915).

The ship also performed a hydrographic survey off the coast of Seychelles around Praslin and Mahe, including approaches to the Port of Victoria. In 2006 the ship was involved in an archaeological survey off the coast of Dwarka, using its sonar equipment to survey and generate a 3D model of the seabed in preparation for the work. The excavation was carried out in association with Archaeological Survey of India, who guided the navy divers.

The Amiens citadel is built on this limestone butte and Rue Saint-Pierre is a slightly inclined path to leave the city from the north. At this narrowing, a network of narrow canals led to the construction of bridges and buildings including textile mills in the Middle Ages. The hydrographic network has always been an important city-operated asset. The river helped shape the identity of the landscape, urban and economic territory.

Further reports on the feasibility of a French colony in New Zealand followed, the last of which was published in 1829. He had already returned to sea by this time; in 1827, he had sailed to India and Burma aboard Chevrette as part of a scientific expedition and the following year, promoted to lieutenant, undertook a hydrographic expedition aboard the Alacrity, serving in the Mediterranean. He was present at the invasion of Algiers in 1830.

Bache finished the season December 7, 1899, and went into winter quarters in Baltimore until May 14, 1900. Between May 26 and 29 the ship went to Norfolk to observe a total eclipse of the sun, returning to Baltimore to prepare for the same combined topographical and hydrographic work below the Potomac River. She finished her last survey and broke off on December 17, 1900, to arrive in New York on December 17, 1900.

Auboyneau was born in Constantinople, where his father was director of the Ottoman Bank. He entered the École navale in 1917 at age 17. From March to November 1918 he took part in patrols along the English Channel as an ensign on board the torpedo boat Typhon. He then served in the Middle East and the Far East for ten years, commanding the hydrographic vessel Alidade, then the gunboat Doudart de Lagrée on the Yangtze.

The water transfer printing process is extensively used to decorate items that range from entire all-terrain vehicles and car dashboards, to small items like bike helmets or other automotive trim. Films can be applied to all types of substrates including plastic, fiberglass, wood, ceramics, and metal. For the most part, if the item can be dipped in water and can be painted using traditional techniques then the hydrographic printing process can be used.

Waswanipi Realities and Adaptations: Resource Management and Cognitive Structure. pp. 144 & appendix A-34 The Olga Lake hydrographic slope is accessible via the James Bay Highway coming from the southwest (from Matagami), then branches northward by cutting the Canet River at the north of Lake Olga. The surface of Olga Lake is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid- April.

Google Maps and other internet maps showed a large landmass named Sandy Island in northern Lansdowne Bank, but did not show an image for it. The non-existence of this phantom island had been proved by French missions in the 1970s, and the information passed to hydrographic services around the world, but it had remained in the World Vector Shoreline Database. In 2012 Australian scientists again proved the island does not exist.

The limits of the Gulf of Saint Lawrence vary between sources. The International Hydrographic Organization defines the limits of the Gulf of Saint Lawrence as follows: > On the Northeast. A line running from Cape Bauld (North point of Kirpon > Island, ) to the East extreme of Belle Isle and on to the Northeast Ledge > (). Thence a line joining this ledge with the East extreme of Cape St. > Charles (52°13'N) in Labrador.

The latest release of SODA (SODA 2.1.6) covers the time period from January 1958 to December 2008. As part of the data assimilation scheme, the system ingests a wide variety of observations including hydrographic profiles, ocean station data, moored temperature and salinity measurements, surface temperature and salinity observations from a variety of instruments (e.g., MBT, XBT, CTD), sea surface temperature (SST) from nighttime infrared observations from satellites, and satellite based sea level altimetry.

The Hydrographic Office and United States Marine Corps moved to Main Navy from a Navy Annex building, located at New York Avenue and 18th Street, and the United States Coast Guard relocated from the Munsey Building. The Navy Department Library was relocated to the Main Navy building in 1923. From 1926 to 1941, a small reinforced concrete roof penthouse on the Main Navy building was used for radio and communication intercepts training.

The Irish Sea, at its greatest width, is and narrows to . The International Hydrographic Organization defines the limits of the Irish Sea (with St George's Channel) as follows, :On the North. The Southern limit of the Inner Seas off the West Coast of Scotland, defined as a line joining the South extreme of the Mull of Galloway (54°38'N) in Scotland and Ballyquintin Point (54°20'N) in Northern Ireland. :On the South.

Gorringe elected to stay in the Navy after the war, receiving a regular commission as a Lieutenant on March 12, 1868, and was promoted to Lieutenant Commander on December 18, 1868. Gorringe discovered the underwater mountain range now known as the Gorringe Sea Bank in 1875, while commanding the exploration vessel . That same year he compiled a book on the exploration of the Río de la Plata, published by the U.S. Hydrographic Office.

The international Inland ENC Harmonization Group (IEHG) was formed in 2003 to facilitate the development of international standards for Inland ENC data. The Russian Federation, Brazil, People's Republic of China, South Korea, Venezuela and Peru have joined the IEHG in the meantime. In 2009 IEHG has been recognized as a Non-Governmental International Organization (NGIO) by the International Hydrographic Organization (IHO). The IEHG is composed of representatives from government, industry and academia.

The sonars and echo sounders allow the vessels to chart waters up to deep.

Collecting hydrographic data as she progressed, she reached T-3 on 17 February. Thence, after conducting tests in cooperation with scientists on the ice island, she got underway for the Bering Strait, the Aleutian Islands, and Hawaii. On 3 March 1960, Sargo, having covered over 11,000 miles (20,000 km), 6,003 miles (11,118 km) under ice, returned to Pearl Harbor with new data on Arctic ice, Arctic waters, and the physiography of the Arctic Basin.

Cairns is currently responsible for all Australian naval activity from Rockhampton to Thursday Island and serves as a home base for one of the navy's thirteen Armidale class patrol boats and two Cape class patrol boats. The base also berths the RAN's entire hydrographic fleet, consisting of two Leeuwin class survey vessels and four Paluma class survey motor launches. Cairns also has operational responsibility for the LADS Flight based at Cairns Airport.

In the 1850s, he commanded the steamer Walker in the Gulf of Mexico on coast survey duty and invented a deep sea sounding apparatus and other hydrographic instruments. In 1861, Sands served on west coast survey duty as commander of the Active. Commissioned captain in 1862, he joined the North Atlantic Blockading Squadron as commander of Dacotah in 1863. In February of that year, Sands participated in the engagement at Fort Caswell.

Norfolk, Virginia, ca. 1916. The Coast and Geodetic Survey acquired her from her owners on 1 July 1915 and placed her in service as a survey ship that year. She operated along the United States East Coast, used by Ernest Lester Jones—Director of the Coast and Geodetic Survey from 1915 to 1929—to ferry dignitaries about in addition to her hydrographic survey work. On more than once occasion, Isis assisted mariners in distress.

Location of Wrangell, Alaska Zimovia Strait is a narrow strait in the Alexander Archipelago in the U.S. state of Alaska. It is about 100 km (62 mi) long and bounded by Wrangell Island to the east and Woronkofski and Etolin Islands to the west. The strait is shown in an 1844 Russian chart, but the name was first published in 1853 on a Russian Hydrographic Department chart as "Proliv Zimov'ya" (English: Winter Strait).

When at sea, she charted hydrographic features, investigated maritime disasters, and performed humanitarian services for the victims of those disasters. On 4 January 1879, Alert departed Yokohama on her way back to the United States. She arrived at the Mare Island Navy Yard on 24 February and began a six-month repair period. On 30 August 1879, the warship set sail from San Francisco on her way back to the Asiatic Station.

Submersible vehicles are a new alternative to classic diving methods. The indoor pool will permit a controlled environment allowing for submersible trials and training, including simulations. This would reduce the risk of subsea operations by moving trials and training into a safe and heavily monitored facility. Testing and training is expected to include hydrographic, pipeline and cable surveys, inspections of wind turbine foundations, vessel hulls and installations, oceanographic studies, and even film production.

A "Laboratory for international marine science" (in German: "Laboratorium für die internationale Meeresforschung") was established by the Commission in 1902. Furthermore, the geographer Otto Krümmel became professor at Kiel University in 1883, strengthening hydrographic work. He wrote the first textbook (2 volumes) on oceanography in German language. The Institute of Zoology and Zoological Museum of Kiel University became the center of marine biological research, led by Adolf Remane (1898-1976) from 1924 to 1934.

SBL systems use this concept to an advantage by adjusting transducer spacing for best resultsAn evaluation of USBL and SBL Acoustic Systems and the Optimization of Methods of Calibration, Philip, The Hydrographic Journal, No. 108 April 2003 When operating from larger ships, from docks or from the sea ice where greater transducer spacing can be used, SBL systems can yield a positioning accuracy and robustness approaching that of sea-floor mounted LBL systems.

In 1933, he became a lecturer in mechanics and mathematical physics in Lund; in 1939, he became professor in the same subject, and in 1961 he became professor of theoretical physics. Gustafson's research focus was first mechanics, and especially flow mechanics with aerodynamics and oceanography applications. During his time as a PhD student, he worked as an assistant in the Swedish Hydrographic-Biological Commission in 1930–1934. Later he was mainly involved in nuclear physics.

This island was the last piece of undiscovered territory in the Soviet Arctic. It was finally located in 1935 when the few remaining unexplored areas in the northern Kara Sea were surveyed by Soviet hydrographic and oceanographic operations on icebreakers to study the sea and ice. The expedition that discovered the island was led by Georgiy Alekseevich Ushakov aboard Icebreaker Sadko. The elusive island was subsequently named after this polar explorer, cartographer and oceanographer.

The vessel was 472 tons displacement/370 gross tons with a registered length of 153.2 feet, beam of 26.2 feet and 10 foot draft of 400 horsepower for a speed of 10.5 knots. She had a capacity for 96 tons of coal and 9 officers and 42 men. Accepted January 18, 1902 the vessel completed outfitting, with personnel and a boat conducting a four-day hydrographic examination in the vicinity of Shooters Island before departure.

The Walters Shoals is a group of submerged mountains off the coast of Madagascar. Despite being south of Cape Sainte Marie - Madagascar and east of Richards Bay at the African coast, the tips of some of the mountains are only below the surface. The Walters Shoals is home to many species of fish, crustaceans, and mollusks. It was discovered in 1963 by the South African Hydrographic Frigate SAS Natal captained by Cmdr Walters.

In 1842, a Compass Branch as part of the Hydrographic Department was established. In 1911, The Compass Branch was affiliated to the Controller of the Navy's Department. Its work in connection with terrestrial magnetism was transferred to the Royal Observatory Greenwich when it was renamed the Compass Observatory. In 1917, it moved to Ditton Park and used the house and its immediate grounds when the compass branch was elevated to a department.

In 1964, O'Bannon took part in the 1965 film In Harm's Way. At 9:00 into the film, as Kirk Douglas' character is welcoming a new transport, O'Bannon is seen full length in the background. Its hull number 450 can be seen somewhat obscured on the starboard bow. O'Bannon first closed the coast of Vietnam during her 1964–65 deployment, when, on 26 December, she left Hong Kong to patrol and conduct hydrographic surveys.

The following 48 hours were unsuitable. On 17 June the meteorologists predicted a break in the weather and Martell ordered the countdown to recommence. Weather balloons indicated that conditions were stable between , with an anomaly between that was not considered significant. The boom defence vessel carried out a hydrographic survey of the Monte Bello Islands G2 was detonated from a tower on Alpha Island at 02:14 UTC (10:14 local time) on 19 June.

In 1796, Blunt sold his interest in the paper to Angier March who continued the publication until it was merged with the Political Gazette in 1797 when the name changed to the Newburyport Herald. When Blunt sold the Impartial Herald, he published the American Coast Pilot in 1796, in Newburyport, Massachusetts. It was published until 1858 by the United States Hydrographic Office, reaching 21 editions by 1867. Its final publication was produced in New York.

The ship operated through the Drake Passage, around Cape Horn, and resupplied a base in the South Orkney Islands (called by the Argentines Órcadas) with trips to South Georgia (called by the Argentines San Pedro Island) and supporting the Argentinean Fisheries Association (Sociedad Argentina de Pesca) whaling station with coal and food supplies. During this time ship was engaged in performing hydrographic and geographic surveys for the preparation of maritime navigation charts.

The Gulf of Riga as seen from Jūrmala, Latvia (January 2018). The International Hydrographic Organization defines the Gulf of Riga's western limit as "A line running from Lyser Ort (57°34'N), in Latvia, to the South extreme of Œsel Island, through this island to Pammerort (22°34'E), thence to Enmast Point, the S extreme of Dagö, through Dagö to Takhkona Point, the North extreme thereof, and on to Spithamn Point in Estonia".

As the recapture of the Philippines gained momentum, the ship steamed from San Francisco on 6 November and arrived at the Manus staging area on 4 December 1944. Moving to Leyte Gulf before Christmas, Hogan sortied with the Minesweeping and Hydrographic Group on 2 January 1945. Kamikaze attacks began soon afterward, and continued during the voyage to Lingayen Gulf. The minesweepers entered the invasion area on 2 January and began their sweeping operations.

An extratropical cyclone entered the South Atlantic Ocean from Santa Catarina early on December 4, 2016. Later, it intensified quickly and then transitioned into a subtropical storm shortly before 22:00 BRST (00:00 UTC on December 5), with the name Eçaí assigned by the Hydrographic Center of the Brazilian Navy. Eçaí started to decay on December 5, and weakened into a subtropical depression at around 00:00 UTC on December 6.

According to the Hydrographic Center of the Brazilian Navy, on December 9, 2017, a subtropical storm formed over the southeastern tip of a South Atlantic Convergence Zone, being located close to the state border between Espírito Santo and Bahia, moving southeastwards away from land. On early December 11, as it moved more southwardly, Guará attained its peak intensity while transitioning to an extratropical cyclone. Shortly thereafter, Guará became fully extratropical, later on the same day.

Practically the entire territory (92%) of Serbia belongs to the Danube (Black Sea) drainage basin. Part of Kosovo (5%) belongs to the Adriatic drainage basin, chiefly via the White Drin river. The rest (3%) in Kosovo and southern Serbia belongs to Aegean basin, chiefly via the Vardar river. Hydrographic map of Serbia The Danube flows 588 km through Serbia or as a border river (with Croatia in the northwest and Romania in the southeast).

In the Royal Navy the master of the fleet was ranked as a "Staff Captain" after 1864, just below the Captain, but he was not considered an executive branch officer and was not eligible for further promotion. Some exceptions were made to this rule, such as transfer to the executive officers list and promotion to Captain of Sir Frederick Evans upon his retirement in 1872, in recognition of his hydrographic survey work and scientific merits.

The word tarim is used to designate the bank of a river that flows into a lake or that is not able to be differentiated from the sands of a desert. This is a characteristic hydrographic feature of many rivers that traverse the sands of the Taklamakan Desert. Another characteristic of the rivers of the Tarim Basin, including the Tarim River itself, is their active migration, that is, the shifting of their beds and banks.

Scott was deployed in June 1960 to map shipwrecks from both World Wars in the English Channel after the arrival of giant tankers. The requirements of those ships changed the minimum of clearance between their hulls and the wrecks below. Scott completed two decades of peacetime hydrographic duties in Home Waters before being retired in 1964 and scrapped in 1965. She located and swept many war-time wrecks while re-surveying coastal Great Britain.

HMAS Leeuwin Fokker 27 formerly used by the service Following the work of explorers, the British Admiralty established a Chart and Chronometer Depot in Sydney in 1897.Slade, in Oldham, 100 Years of the Royal Australian Navy, p. 166 The depot was to supplement the activities of Royal Navy survey ships in Australian waters. In 1913, the depot was taken over by the Australian government and was renamed the RAN Hydrographic Depot.

The first general charting of the New Zealand coast was done with great competence by Cook on his first visit in 1769. The chart was published in 1772 and remained current for 66 years.Hooker, Brian Official General Charts of New Zealand 1772–1885 By 1840 several Royal Navy ships were engaged in hydrographic surveys directed by the Admiralty. Captain Owen Stanley, on HMS Britomart, drew up an Admiralty chart of the Waitematā Harbour.

During the remainder of September, Refresh assisted task group TG 52.3 in minesweeping operations in the East China Sea approaches to Nagasaki and Sasebo, Japan, and in the Goto Archipelago, primarily in the area of Fukse, southwest of Kyūshū. Arriving Sasebo 1 October, Refresh was assigned several hydrographic missions, conducting soundings in shoal waters southwest of Kagoshima, Kyūshū, Japan. After upkeep in Sasebo, she continued to operate in Japanese waters through the new year.

His inclination toward the sea began at a young age; at 14 he enlisted himself aboard the sloop Andaluz. After 12 years of service in the Spanish navy, he was promoted to assistant of the maritime department of Cartagena. In 1772 Don José de Mazarredo went to the Philippines aboard the Frigate Venus. In 1774 he was transferred to the frigate Rosalía and took part in a hydrographic campaign in South America.

The UDT's entered the Vietnam War in 1958, UDTs delivered small watercraft far up the Mekong River into Laos. In 1961, naval advisers started training South Vietnamese personnel in South Vietnam. The men were called the Liên Đoàn Người Nhái (LDNN) or Vietnamese Frogmen, which translates as "Frogmen Team." UDT teams carried out hydrographic surveys in South Vietnam's coastal waters and reconnaissance missions of harbors, beaches and rivers often under hazardous conditions and enemy fire.

The patrol boats also provide indirect benefits to the operating nations. Operation of the Pacifics has often required the expansion of maritime facilities, providing jobs and facilitating access for other ships. In addition to the economic boost from fishing fees and fines, improved hydrographic charts created by the ships contributes to boosting tourism. The ships are seen as miniature warships, and are a point of pride and prestige for the island nations.

Relief The relief is predominantly rugged and abrupt, with high slopes and narrow valleys within the mountains. The eastern sector constitutes a depression in the Serranía del Litoral. The Guaire River, which runs through the city of Caracas, divides the sector into two strips that are differentiated by their decline: the Valles del Tuy and La Depresión de Barlovento. The waters that make up the hydrographic network of the state are mostly short course.

She continued that work through the 1950s, interrupting it only for type training; mine planting exercises; ASW exercises; fleet exercises; occasional participation in NATO or joint United States-Canadian exercises off the coasts of the Atlantic Provinces and northern New England; and, from January to June 1957, operations in the Caribbean Sea and the Guiana and Brazilian basins for the Hydrographic Office. On her return, she resumed her primary function, training submarine school students.

Acosta had conversations with the pilot of Sarmiento's fleet, and was allowed to inspect his chart, thus obtaining much hydrographic information, and particulars respecting the tides in the straits. He also conversed with the new Viceroy Don Martín Henríquez on the same subject.op. cit., de Acosta, p.vi Acosta founded a number of colleges, among them those of Arequipa, Potosí, Chuquisaca, Panama and La Paz, but met with considerable opposition from the Viceroy Toledo.

He was born in Jena, the son of the Baltic- German historian Alexander Brückner and Lucie Schiele. After an education at the Karlsruhe gymnasium, beginning in 1881 he studied meteorology and physics at the University of Dorpat, graduating in 1885. He joined the Deutsche Seewarte (German Hydrographic Office) in Hamburg, then, following studies at Dresden and Munich, he became a professor at the University of Bern in 1888. The same year he married Ernestine Steine.

Between April and November 1884 she participates in the Argentine expedition to the South Atlantic to implement the Boundary Treaty of 1881, which concluded with the possession of Ushuaia on 12 October. She returned to Buenos Aires in late November 1884. From 1885 to 1889 she performs various tasks in the Paraná, Uruguay and de la Plata rivers, including hydrographic survey. In 1894 she is repaired and modernized, including replacement of the boilers.

The first European to sight the island was James Johnstone, one of George Vancouver's officers during his 1791-95 expedition, in 1793. He only charted its north coast, not realizing it was an island. The island was named for Lieutenant Woronkovski of the Imperial Russian Navy, who explored the south coast of the Alaska Peninsula in 1836; the name was published in 1848 on a Russian Hydrographic Department chart as "O(strov) Voronkovskiy".

Ledge Point is a small coastal township 105 km north of Perth, Western Australia. It was established to service the local fishing and crayfishing industries. The town's name originates from the nearby coastal feature of the same name, a series of rocky ledges on the point that was first described in an 1875 hydrographic survey. The Gingin Road Board requested that land be set aside in the area in 1937 for camping and recreation purposes.
