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.

Ice rise an elevation of the otherwise totally flat ice shelf

An ice rise is a clearly defined elevation of the otherwise totally flat ice shelf, typically dome-shaped and rising 100 to 200 metres above the surrounding ice shelf. An ice rise forms where the ice shelf touches the rocky seabed because of an elevation in the seabed that remains below sea level.. The ice shelf flows over the seabed elevation, completely covering it with ice, thereby forming an ice rise. The resulting tension forms crevasses around the ice rise.

Wordie Ice Shelf ice shelf in Antarctica

The Wordie Ice Shelf was a confluent glacier projecting as an ice shelf into the SE part of Marguerite Bay between Cape Berteaux and Mount Edgell, along the western coast of Antarctic Peninsula.

The plateau reaches a maximum height of 3,275 metres (10,745 ft) in Mount Blackburn at the southern end. The northwestern side of the plateau is marked by the steep rock cliffs of Watson Escarpment; the southeastern side grades gradually to the elevation of the interior ice. It was mapped by the United States Geological Survey from ground surveys and from U.S. Navy aerial photography, 1960–64, and named by the Advisory Committee on Antarctic Names for the several branches of the University of California which have sent numerous researchers to work in Antarctica.

Cape Calmette is a cape marking the western extremity of a rocky peninsula which rises more than 625 metres (2,050 ft) and projects from the west coast of Graham Land for 3 nautical miles (6 km) to form the southern shore of Calmette Bay. It was discovered in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, who from a distance mistook this cape for an island; the British Graham Land Expedition under John Rymill, 1934–37, determined the true nature of the feature. It was named by Charcot for Gaston Calmette, editor of Le Figaro, who furnished the French Antarctic Expedition with copies of this newspaper for the two years preceding the expedition.

It flows southwest along the north side of Butson Ridge into Marguerite Bay between Cape Calmette and the Debenham Islands. The glacier was first roughly surveyed by the British Graham Land Expedition, 1936–37, and resurveyed by the Falkland Islands Dependencies Survey, 1946–50. It was named by the UK Antarctic Place-Names Committee for George B. McClary, father of Nelson McClary, mate on the Port of Beaumont during the Ronne Antarctic Research Expedition, 1947–48.

Sölch Glacier

Sölch Glacier is a glacier on the Pernik Peninsula of the Loubet Coast in Graham Land, flowing west to Salmon Cove just north of Kanchov Peak on the east side of Lallemand Fjord. It was mapped from air photos taken by the Falkland Islands and Dependencies Aerial Survey Expedition, 1956–57, and named by United Kingdom Antarctic Place-Names Committee for Johann Sölch (1883–1951), an Austrian glacial geologist and glaciologist.

Relay Hills is a group of low, ice-covered hills, mainly conical in shape, between Mount Edgell and Kinnear Mountains in western Antarctic Peninsula. First roughly surveyed from the ground by British Graham Land Expedition (BGLE), 1936-37. Photographed from the air by Ronne Antarctic Research Expedition (RARE), November 1947. Resurveyed by Falkland Islands Dependencies Survey (FIDS), November 1958. The name, applied by the United Kingdom Antarctic Place-Names Committee (UK-APC), arose because both the BGLE and the FIDS sledging parties had to relay their loads through this area to the head of Prospect Glacier.

Landauer Point is a point on the east coast of Adelaide Island, marking the west side of the north entrance to Tickle Channel in Graham Land, Antarctica. It was mapped by the Falkland Islands Dependencies Survey from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, and the Falkland Islands and Dependencies Aerial Survey Expedition, 1956–57. The point was named by the UK Antarctic Place-Names Committee for Joseph K. Landauer, an American physicist who has studied the mechanical properties of ice and glacier flow.

League Rock is a distinctive rounded rock lying southwest of Box Reef, 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 because the rock lies one league distant from what was then Adelaide Station.

Linchpin Ice Rise is a small ice rise northeast of Miller Ice Rise, situated near the ice front of Wordie Ice Shelf on the Fallières Coast of Antarctica. The feature was mapped from U.S. Landsat imagery, 1974–79, and was so named by the UK Antarctic Place-Names Committee because the ice rise plays a key role (linchpin) in maintaining the position of the ice front, as observed in 1979.

Beacon Hill (Antarctica)

Beacon Hill is an ice-covered, dome-shaped hill of elevation 1,810 m which rises 120 m above the surrounding plateau ice surface. It is situated in the south part of Hemimont Plateau in Graham Land, Antarctica 2.5 mi northeast of McLeod Hill. The hill surmounts the divide between Northeast Glacier and Bills Gulch. It was surveyed and named by the U.S. Antarctic Service (USAS), 1939-41; the hill may have been the site of a beacon at that time. The U.S. Antarctic Service (USAS) operated a plateau weather station close southwestward of the hill throughout November and December 1940.
