Bergan Castle
Bergan Castle () is a castle-like nunatak rising to to the southwest of Mount Dewar in Shotton Snowfield, Shackleton Range. It was photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey, 1968–71. In association with the names of pioneers of polar life and travel grouped in this area, it was named by the 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 ... in 1971 after Ole Ferdinand Bergan (1876–1956), Norwegian inventor who designed Bergan's "meis" (carrying frames) and rucksacks, patented in Norway in 1909.

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] |
Mount Dewar
Mount Dewar () is a mountain rising to about to the southwest of Aronson Corner in the Pioneers Escarpment, Shackleton Range. It was photographed from the air by the U.S. Navy in 1967 and surveyed by the British Antarctic Survey from 1968 to 1971. In association with the names of pioneers of polar life and travel grouped in this area, it was named in 1971 by the UK Antarctic Place-Names Committee after Sir James Dewar, a Scottish chemist and physicist who invented the thermos flask about 1892.

Shotton Snowfield
Shotton Snowfield () is a large snowfield between Herbert Mountains and Pioneers Escarpment on the north and Read Mountains on the south, in the Shackleton Range of Antarctica. Location The Shackleton Range is an ice-covered plateau between high that rises between two large glaciers. It is a rectangular horst rising above major fault zones now under the Slessor Glacier to the north and Recovery Glacier glacier to the south. The center of the range is covered by a long ice cap stretching from the Fuchs Dome in the west to Shotton Snowfield in the east, and bounded by cliffs as high as . The Shotton Snowfield extends east from the Gordon Glacier, which separates it from Fuchs Dome. The Read Mountains separate it from the Recovery Glacier to the south. The Herbert Mountains are northwest of the snowfield, and further east the Pioneers Escarpment lies between it and the Slessor Glacier to the north. The snowfield stretches eastward until it merges into the Antarctic ice sheet. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shackleton Range
The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to , it extends in an east–west direction for about between the Slessor and Recovery glaciers. The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16. Surveys The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft.

The Ordovician-Early Devonian Blaiklock Glacier Group (475 Ma) also unconformably overlies the Shackleton Range Metam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic 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.
