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.
Stefan Ice Piedmont is a small ice piedmont at the northwest extremity of Pernik Peninsula, Loubet Coast in Graham Land, overlying the coast between Cape Rey and Holdfast Point. Mapped from air photos taken by Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) (1956–57). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Josef Stefan (1835–1893), Austrian physicist who in 1889 pioneered the theory of heat flow in a freezing ice layer and first used it to calculate rates of sea ice growth in the Arctic.
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.
Shull Rocks is a chain of low snow-covered rocks and one small island, lying in Crystal Sound about 10 miles (16 km) northwest of Cape Rey, Graham Land. Mapped from surveys by Falkland Islands Dependencies Survey (FIDS) (1958–59). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Clifford G. Shull, American physicist who used neutron diffraction to determine the position of the hydrogen atoms in ice.
O'Hara Glacier is a glacier just west of Ackroyd Point, flowing northwest into the south side of Yule Bay, Victoria Land. Mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960-63. Named by Advisory Committee on Antarctic Names (US-ACAN) for Norbert W. O'Hara, a member of the United States Antarctic Research Program (USARP) party which conducted studies of the Ross Ice Shelf, 1965-66.
Allen Knoll is a steep-sided snow dome rising from a flat snowfield 2 nautical miles (4 km) northwest of the head of Russell West Glacier, Trinity Peninsula, Antarctica.

The Butler Rocks are two rock nunataks, 910 metres (3,000 ft) high, standing 2.5 nautical miles (5 km) southwest of Vanguard Nunatak in the northern Forrestal Range, Pensacola Mountains. They were mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1956–66, and named by the Advisory Committee on Antarctic Names for William A. Butler, aerographer, Ellsworth Station winter party, 1957.
The Chester Mountains are a group of mountains just north of the mouth of Crevasse Valley Glacier and 10 nautical miles (20 km) north of Saunders Mountain in the Ford Ranges of Marie Byrd Land. They were mapped by the Byrd Antarctic Expedition (1933–35) and named for Colby M. Chester, president of General Foods Corporation, who gave generous support to the Byrd expeditions.

It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1956–66, and named by the Advisory Committee on Antarctic Names for John H. Childs, a builder at Ellsworth Station, winter 1958.
Voit Peak is a peak between Drummond and Hopkins Glaciers on the west coast of Graham Land. Photographed by the Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) in 1956-57. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Carl von Voit (1831–1908), German physiologist, pioneer of basic metabolic studies who published what was probably the first standard of human calorie requirements in 1881.
Crystal Sound is a sound in Antarctica between the southern part of the Biscoe Islands and the coast of Graham Land, with northern limit Cape Evensen to Cape Leblond and southern limit Holdfast Point, Roux Island, Liard Island and the Sillard Islands. It was so named by the UK Antarctic Place-Names Committee in 1960 because many features in the sound are named for men who have undertaken research on the structure of ice crystals. To the north of Crystal Sound, many geographical features are named after physiologists.
Cumbers Reef is a group of rocks aligned in an arc forming the north and west parts of the Amiot Islands, off the southwest part of Adelaide Island. It was named by the UK Antarctic Place-Names Committee for Roger N. Cumbers, 3rd officer of RRS John Biscoe, 1961–62, the ship which assisted the Royal Navy Hydrographic Survey Unit in the charting of this area in 1963.
Möller Trough is an undersea trough in the Weddell Sea named for geodesist Dietrich Möller, former President of the German Society for Polar Research. The name was proposed by Dr. Heinrich Hinze of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, and was approved by the Advisory Committee for Undersea Features in June 1997.
Fleming Glacier is a broad glacier 25 nautical miles (46 km) long on the west side of the Antarctic Peninsula, flowing west-northwest and terminating in Forster Ice Piedmont to the east of the Wordie Ice Shelf. The glacier was charted by the British Graham Land Expedition (BGLE) under John Rymill, 1934–37, and was photographed from the air by the United States Antarctic Service on September 29, 1940. This hitherto unnamed feature was named by the Advisory Committee on Antarctic Names in 1947 for Reverend W.L.S. Fleming, Dean of Trinity Hall, Cambridge University; also, chaplain, chief scientist, and geologist of the BGLE.
Goodenough Glacier is a broad sweeping glacier to the south of the Batterbee Mountains, flowing from the west shore of Palmer Land, Antarctica, into George VI Sound and the George VI Ice Shelf. It was discovered in 1936 by A. Stephenson, W.L.S. Fleming, and George C.L. Bertram of the British Graham Land Expedition under John Rymill, while exploring George VI Sound, and was named by Rymill after Margaret Goodenough, wife of Admiral Sir William Goodenough, the latter being one of Rymill's principal supporters in raising funds for the expedition.
Cape Hansen is a cape which separates Marshall Bay and Iceberg Bay on the south coast of Coronation Island, in the South Orkney Islands, Antarctica. The name appears on a chart based upon a running survey of the islands in 1912–13 by Petter Sørlle, a Norwegian whaling captain.
Menelaus Ridge is a snow-covered ridge having four small summits at about 1,370 metres (4,500 ft), between Mount Agamemnon and Mount Helen in the Achaean Range of central Anvers Island, in the Palmer Archipelago, Antarctica. It was surveyed in 1955 by the Falkland Islands Dependencies Survey, and was named by the UK Antarctic Place-Names Committee, in association with other names in the area, for Menelaus, husband of Helen and younger brother of Agamemnon in Homer's Iliad.
MacNamara Glacier is a glacier in the Patuxent Range of the Pensacola Mountains in Antarctica, draining northeastward between the Thomas Hills and Anderson Hills to Foundation Ice Stream. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1956–66, and was named by the Advisory Committee on Antarctic Names for Edlen E.

The Kelvin Crests are a line of steep-sided elevations with ice-covered cliffs 5 nautical miles (9 km) long, on the north side of Airy Glacier near its junction with Forster Ice Piedmont on the west side of the Antarctic Peninsula. Roughly surveyed by the British Graham Land Expedition in 1936–37, they were photographed from the air by the Ronne Antarctic Research Expedition in 1947. They were surveyed from the ground, from the southwest only, by members of the Falkland Islands Dependencies Survey, December 1958, and completely mapped by the United States Geological Survey, 1974. The feature was named by the UK Antarctic Place-Names Committee for William Thomson, 1st Baron Kelvin, a British physicist and engineer who made substantial improvements in the design of magnetic compasses, 1873–78, and invented the Thomson sounding machine in 1878.
Rhyolite Islands is a group of islands and rocks which extend 4 nautical miles (7 km) in an east-west direction, lying close off the Rymill Coast of Palmer Land opposite the north side of the mouth of Eureka Glacier, in George VI Sound. Surveyed in 1948 by Falkland Islands Dependencies Survey (FIDS) and so named from the rock of which the islands are largely composed. The name "Grupo Maipo," after the Chilean oil tanker Maipo, may refer to these islands roughly charted by the Chilean Antarctic Expedition, 1947, in about 6954S, 6833W.
Levy Island is an isolated snow-covered island in Crystal Sound, Antarctica, about 7.5 nautical miles (14 km) east of Gagge Point, Lavoisier Island. It was mapped from air photos taken by the Ronne Antarctic Research Expedition (1947–48) and surveys by the Falkland Islands Dependencies Survey (1958–59). The island was named by the UK Antarctic Place-Names Committee for Henri A. Levy, an American physical chemist who, with S.W. Peterson, determined the location of the hydrogen atoms in ice by neutron diffraction, in 1957.
