Challenger Island ( 64°21′S61°35′W / 64.350°S 61.583°W / -64.350; -61.583 Coordinates: 64°21′S61°35′W / 64.350°S 61.583°W / -64.350; -61.583 ) is an island lying just north of Murray Island, off the west coast of Graham Land. The name was used in 1906 by J. Gunnar Andersson of the Swedish Antarctic Expedition under Otto Nordenskiöld, 1901–04.

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.

Murray Island (Antarctica)

Murray Island, also sometimes known as Bluff Island, is an island 6 km long lying at the south-west side of Hughes Bay, off the west coast of Graham Land, Antarctica. The feature has been known to sealers operating in the area since the 1820s, although it was shown on charts as part of the mainland. In 1922 the whale catcher Graham passed through the channel separating it from the mainland, proving its insularity. It was named in association with Cape Murray, the seaward extremity of the island.

Graham Land geographical object

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.

It was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos from 1961-67 and named by Advisory Committee on Antarctic Names (US-ACAN) for Herbert T. Ueda who, with B. Lyle Hansen, was in charge of the deep core drilling program at Byrd Station, summers 1966-67 and 1967-68.

Imshaug Peninsula is a broad, snow-covered peninsula at the south side of Lehrke Inlet on the east coast of Palmer Land, Antarctica.

Arrol Icefall is a steep icefall about 3 miles (5 km) long, originating on the south side of Detroit Plateau, Graham Land, about 8 miles (13 km) northwest of Cape Worsley. The 11-km long glacier featuring this icefall is situated southwest of Akaga Glacier and north of Aleksiev Glacier, and flows eastwards into Odrin Bay. The feature was mapped from surveys by the Falkland Islands Dependencies Survey (1960–61), and named by the United Kingdom Antarctic Place-Names Committee after the Arrol-Johnston car, which was adapted for use by Ernest Shackleton's Nimrod Expedition (1907–09) and was the first mechanical transport used in Antarctica.

Boxing Island is a small island lying in Charlotte Bay east of Harris Peak, off the west coast of Graham Land. It was first charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, and so named by members of the Falkland Islands Dependencies Survey because they first saw it on Boxing Day 1956.

Defant Glacier is a glacier 2 nautical miles (4 km) wide at its mouth, which flows east-southeast to the west side of Violante Inlet, on the east coast of Palmer Land. It was discovered and photographed from the air in December 1940 by the United States Antarctic Service; during 1947 the glacier was photographed from the air by members of the Ronne Antarctic Research Expedition, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named by the FIDS for Albert Defant, an Austrian meteorologist and oceanographer who was Professor of Oceanography at the "Friedrich-Wilhelms-Universität" and also Director of the "Institut and Museum für Meereskunde" in Berlin, Germany, from 1926 to 1945.
