Director Nunatak
Director Nunatak () is a conspicuous nunatak standing between the heads of Balch Glacier and Breitfuss Glacier, in Graham Land in Antarctica. It was photographed by Hunting Aerosurveys Ltd in 1955–57, and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). It was so named by the UK Antarctic Place-Names Committee in 1958 because this nunatak was used as a landmark by a FIDS sledge party from Detaille Island in 1957 when traveling on Avery Plateau Avery Plateau () is an ice-covered plateau, about long and rising to about , midway between Loubet Coast and Foyn Coast in Graham Land, Antarctica. It borders Hemimont Plateau on the south and Bruce Plateau on the north. The first sighting of th .... References Nunataks of Graham Land Loubet Coast {{LoubetCoast-geo-stub ...

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] |
Balch Glacier
Balch Glacier () is a glacier long, on the east coast of Graham Land, flowing southeast into Mill Inlet, to the south of Gould Glacier. History It was first surveyed by the Falkland Islands Dependencies Survey in 1946–47, and named "East Balch Glacier". With "West Balch Glacier" it was reported to fill a transverse depression across Graham Land, but further survey in 1957 showed that there is no close topographical alignment between the two. The name "Balch", for Edwin S. Balch, an American Antarctic historian, has been limited to this glacier and an entirely new name, Drummond Glacier, approved for the west glacier.

Breitfuss Glacier
Breitfuss Glacier () is a glacier long, which flows southeast from Avery Plateau into Mill Inlet to the west of Cape Chavanne, on the east coast of Graham Land. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition in 1947. It was named by the FIDS for Leonid Breitfuss, a German polar explorer, historian, and author of many polar bibliographies.

Graham Land
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. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting Aerosurveys Ltd
Hunting Aerosurveys Ltd was a British aerial photography company founded by Percy Hunting in 1944. Its operations became more diversified under the name Hunting Surveys. History The firm incorporated Aerofilms Ltd and the Aircraft Operating Company. In 1947 it was using three types of aircraft: Austers, a Percival Proctor and a de Havilland Dragon Rapide and planned to acquire one or more Percival Mergansers. The company had contracts for work surveying for tin mining in Nigeria; oil in Arabia, Venezuela and Colombia; timber in Ontario; and mapping in Australia & Hong Kong (in 1963). Between 1957 and 1964, Hunting operated a specially converted Auster Autocar for smaller scale aerial survey work. In 1960 the firm was merged with Hunting Geophysics Ltd to form Hunting Surveys Ltd. Threatened with closure in the mid-1980s, it was merged with sister company Hunting Aerofilms Ltd to become simply Aerofilms Ltd in 1987. The new company was able to provide state-of-the-art seria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
Detaille Island
Detaille Island is a small island off the northern end of the Arrowsmith Peninsula in Graham Land, Antarctica. From 1956 to 1959 it was home to "Base W" of the British Antarctic Survey and closed after the end of the International Geophysical Year (IGY). It is now often visited by Antarctic cruise ships but is otherwise unoccupied. Thanks to the men's hasty departure and the necessity that they take little with them, Base W is an eerily preserved time capsule of 1950s Antarctic life. The base had been intended to host dog-sledging survey parties which would cross the sea ice to the nearby Antarctic Peninsula, but the ice was dangerously unstable. When Base W was vacated, heavy sea ice prevented resupply ship ''Biscoe'' from approaching closer than , despite the assistance of two U.S. icebreakers. So the men were forced to close up the base, load sledges with only their most valuable gear and use dog teams to reach the ship. Station W Station W was established in 1956 as a Bri ...

Avery Plateau
Avery Plateau () is an ice-covered plateau, about long and rising to about , midway between Loubet Coast and Foyn Coast in Graham Land, Antarctica. It borders Hemimont Plateau on the south and Bruce Plateau on the north. The first sighting of this plateau is not certain, but it was presumably seen in January and February 1909 by members of the French Antarctic Expedition under Jean-Baptiste Charcot from various positions in the Matha Strait. It was surveyed in 1946–47 by the Falkland Islands Dependencies Survey, and named by the UK Antarctic Place-Names Committee (1955) after Captain George Avery, master of the cutter ''Lively'', who, with Captain John Biscoe in the brig ''Tula'', approached this part of the Antarctic Peninsula in February 1832.
