Fin Nunatak
Fin Nunatak () is a nunatak, high, in the middle of Casey Glacier, near the east coast of Palmer Land, Antarctica. The nunatak was photographed from the air by Sir Hubert Wilkins on 20 December 1928, and was first mapped from these photos by W.L.G. Joerg. It was surveyed by the Falkland Islands Dependencies Survey in December 1960. The name by the UK Antarctic Place-Names Committee is suggested by the fin A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fin ...-like shape of the feature.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casey Glacier
Casey Glacier () is a glacier wide, flowing east into Casey Inlet on the east coast of Palmer Land. It was discovered by Sir Hubert Wilkins on an aerial flight of December 20, 1928. Wilkins believed the feature to be a channel cutting completely across the Antarctic Peninsula, naming it Casey Channel after Rt. Hon. Richard G. Casey. Correlation of aerial photographs taken by Lincoln Ellsworth in 1935 and preliminary reports of the British Graham Land Expedition, 1934–37, led W.L.G. Joerg to interpret this glacier to be what Wilkins named Casey Channel. This interpretation is borne out by the results of subsequent exploration by members of the East Base of the United States Antarctic Service The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ... in 1940.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, 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° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

Sir Hubert Wilkins
Sir George Hubert Wilkins MC & Bar (31 October 188830 November 1958), commonly referred to as Captain Wilkins, was an Australian polar explorer, ornithologist, pilot, soldier, geographer and photographer. He was awarded the Military Cross after he assumed command of a group of American soldiers who had lost their officers during the Battle of the Hindenburg Line, and became the only official Australian photographer from any war to receive a combat medal. He narrowly failed in an attempt to be the first to cross under the North Pole in a submarine, but was able to prove that submarines were capable of operating beneath the polar ice cap, thereby paving the way for future successful missions. The US Navy later took his ashes to the North Pole aboard the submarine USS ''Skate'' on 17 March 1959. Early life Hubert Wilkins was a native of Mount Bryan East, South Australia, the last of 13 children in a family of pioneer settlers and sheep farmers. He was born at Mount Bryan East, ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
