Hakurei Seamount ( 62°52′S140°49′E / 62.867°S 140.817°E / -62.867; 140.817 Coordinates: 62°52′S140°49′E / 62.867°S 140.817°E / -62.867; 140.817 ) is a seamount located off Adélie Land, Antarctica. The name, approved by the Advisory Committee for Undersea Features in July 1999, is for the RV Hakurei-maru which conducted a detailed survey of the area. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Seamount A mountain rising from the ocean seafloor that does not reach to the waters surface

A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface, and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. They are defined by oceanographers as independent features that rise to at least 1,000 m (3,281 ft) above the seafloor, characteristically of conical form. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat-top seamounts are called "guyots" or "tablemounts"

Adélie Land Frances territorial claim in Antarctica

Adélie Land is a claimed territory on the continent of Antarctica. It stretches from a coastline area along the Great Southern Ocean inland all the way to the South Pole. France administrates it as one of five districts of the French Southern and Antarctic Lands since 1955 and apply the Antarctic Treaty System rules since 1961. Article 4 deals with territorial claims, and although it does not renounce or diminish any preexisting claims to sovereignty, it also does not prejudice the position of Contracting Parties in their recognition or non-recognition of territorial sovereignty. France has had a permanent station in Adélie Land since April 9, 1950. The current Dumont d'Urville Station has a winter population around 33, but this goes up to about 78 during the Antarctic summer.

It was named in 1992 by the Advisory Committee on Antarctic Names after Larry Leon Amos, a civil engineer with the United States Geological Survey (USGS), and a member of the USGS two man astronomic surveying team to South Pole Station and Byrd Station in the 1969–70 field season. Among other work, the team established the position of the Geographic South Pole and established a tie to the Byrd Ice Strain net which had been under study for several years.

Beacon Valley is an ice-free valley between Pyramid Mountain and Beacon Heights, in Victoria Land. It was mapped by the British Antarctic Expedition, 1910–13, and named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) after Beacon Heights.

Carbutt Glacier is a glacier entering Goodwin Glacier to the east of Maddox Peak, close east of Flandres Bay on the west coast of Graham Land. The glacier appears on an Argentine government chart of 1954. It was named by the UK Antarctic Place-Names Committee in 1960 for John Carbutt (1832–1905), American photographer who introduced the first emulsion-coated celluloid photographic cut films, in 1888.

The Central Masson Range is the central segment of the three parts of the Masson Range, Antarctica. It rises to 1,120 metres (3,670 ft) and extends 4 nautical miles (7 km) in a north-south direction. The Masson Range was discovered and named by the British Australian New Zealand Antarctic Research Expedition, 1929–31, under Douglas Mawson. This central range was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named "Mekammen". The approved name, suggested by the Antarctic Names Committee of Australia in 1960, more clearly identifies the feature as a part of Masson Range.
