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.

A headland is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape. Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliffs.

Bourgeois Fjord landform

Bourgeois Fjord is an inlet, 30 miles (50 km) long in a northeast–southwest direction and 3 to 5 miles wide, lying between the east sides of Pourquoi Pas Island and Blaiklock Island and the west coast of Graham Land. It separates Loubet Coast to the north from Fallières Coast to the south. The fjord was discovered by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for Colonel Joseph E. Bourgeois, Director of the Geographic Service of the French Army. The outline of this inlet was more accurately delineated in 1936 by the British Graham Land Expedition under John Rymill.

It was first sighted and roughly charted in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot. It was surveyed in 1936 by the British Graham Land Expedition and in 1948 by the Falkland Islands Dependencies Survey (FIDS). It was so named by FIDS because the peak marks the granite-volcanic contact in the cliffs which is visible at a considerable distance.

Neb Bluff

Neb Bluff is a conspicuous rock bluff 6 nautical miles (11 km) south of Orford Cliff on the west coast of Pernik Peninsula, Loubet Coast in Graham Land, overlooking the east side of Lallemand Fjord. Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1956 and so named because of its snout-like appearance.

Perutz Glacier is a glacier, 10 nautical miles (18 km) long and 2 nautical miles (3.7 km) wide, which flows west-northwest from Hemimont Plateau into Bourgeois Fjord, close east of Thomson Head, on the west coast of Graham Land, Antarctica. The mouth of the glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. The entire glacier was surveyed in 1946-47 and 1948-49 by the Falkland Islands Dependencies Survey (FIDS), and named by them for Max F. Perutz of the Cavendish Laboratory, Cambridge, who has made important studies on the mechanism of glacier flow.

The Eland Mountains are a range of mountains which rise above 2,440 metres (8,000 ft) and extend about 20 nautical miles (40 km) in a northeast–southwest direction along the south side of Clifford Glacier, on the east coast of Palmer Land. The mountains were discovered in 1936 by the British Graham Land Expedition, and they appear in aerial photographs taken by the United States Antarctic Service in September 1940. During 1947 they were photographed from the air by members of the Ronne Antarctic Research Expedition, who in conjunction with the Falkland Islands Dependencies Survey (FIDS), charted them from the ground. The name Eland, Lady Clifford's maiden name, was given in 1952 by Sir Miles Clifford, Governor of the Falkland Islands, at the request of members of the FIDS staff.

Sanctuary Islands is a group of small islands lying just off the west side of Chavez Island, 0.5 nautical miles (0.9 km) southwest of Link Stack, off the west coast of Graham Land. Charted by the British Graham Land Expedition (BGLE) under Rymill, 1934-37. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 because these islands provided sheltered camping sites for Falkland Islands Dependencies Survey (FIDS) sledging parties from the Prospect Point station in 1957, and there are several small boat anchorages which were used by the British Naval Hydrographic Survey Unit's motor-launch in 1957-58.

Snowshoe Glacier is a glacier 8 nautical miles (15 km) long flowing west from a col in the southwest flank of Neny Glacier into Neny Fjord, western Graham Land. Roughly surveyed from the ground (1936) and photographed from the air (1937) by British Graham Land Expedition (BGLE). Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1949. The name was suggested by K.S.P. Butler of the FIDS in 1948 because the shape of the glacier with its narrow head and wide mouth resembles a snowshoe.

Hoskins Peak is a peak 3 nautical miles (6 km) west of Contact Peak in southern Pourquoi Pas Island, Graham Land, Antarctica. It was mapped by the Falkland Islands Dependencies Survey (FIDS) from surveys, 1956–59, and named by the UK Antarctic Place-Names Committee for Arthur K. Hoskins, a FIDS geologist at Stonington Island in 1958 and Horseshoe Island in 1959.
