It was mapped by the Falkland Islands Dependencies Survey from surveys and from air photos, 1956–59, and named by the UK Antarctic Place-Names Committee after Wilson A. Bentley, American meteorologist and specialist in microphotography of snow and ice crystals; joint author with W.J. Humphreys of Snow Crystals.

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.

The Seue Peaks are peaks located on the Antarctic Peninsula, standing between Bentley Crag and Mount Rendu on Arrowsmith Peninsula in Graham Land. They were mapped by the Falkland Islands Dependencies Survey from surveys and air photos from 1956 to 1959, and named by the UK Antarctic Place-Names Committee for Christian Martini de Seue, a Norwegian surveyor and glaciologist who made pioneer measurements of glacial flow in Norway around 1870.

Arrowsmith Peninsula

Arrowsmith Peninsula is a cape about 40 miles (64 km) long on the west coast of Graham Land, west of Forel Glacier, Sharp Glacier and Lallemand Fjord, and northwest of Bourgeois Fjord, with Hanusse Bay lying to the northwest. It was surveyed by the Falkland Islands Dependencies Survey in 1955-58 and named for Edwin P. Arrowsmith, Governor of the Falkland Islands.

Martin Glacier is a glacier, 3 nautical miles (6 km) wide and 9 nautical miles (17 km) long, which flows west and then northwest from the south side of Mount Lupa to the southeast corner of Rymill Bay where it joins Bertrand Ice Piedmont, on the west coast of Graham Land, Antarctica. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, and was resurveyed in 1948–1949 by the Falkland Islands Dependencies Survey. The glacier was named for James H. Martin, a member of the British Australian and New Zealand Antarctic Research Expedition (1929–1931) under Sir Douglas Mawson, and first mate of the Penola during the BGLE.

Alberts Glacier glacier in Antarctica

Alberts Glacier is a heavily crevassed glacier in Antarctica. It is about 8 miles (13 km) long, and flows east from Avery Plateau, Graham Land, until entering Mill Inlet between Balch Glacier and Southard Promontory. The glacier was photographed from the air by the U.S. Navy in 1968. It was delineated from these photographs by Directorate of Overseas Surveys, 1980, and positioned from surveys by Falkland Islands Dependencies Survey, 1947–57. In association with the names of Antarctic historians around the area, it was named by United Kingdom Antarctic Place-Names Committee after Fred G. Alberts, an American toponymist, and secretary of the Advisory Committee on Antarctic Names 1949–80.

Crouse, a construction man with the Ellsworth Station winter party, 1957.

Dallmann Seamount is a seamount named for polar explorer Eduard Dallmann, who surveyed the area west of Graham Land up to 66°S. The name was proposed by Dr. Rick Hagen 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. Minimal depth is 2100m.
