Terminus Nunatak
Terminus Nunatak () is a conspicuous nunatak, 670 m, standing between Eureka and Riley Glaciers and 0.5 nautical miles (0.9 km) inland from George VI Sound, on the west coast of Palmer Land. This nunatak was first photographed from the air on November 23, 1935, by Lincoln Ellsworth, and was mapped from these photographs by W.L.G. Joerg. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because the nunatak marks the end of the sledge route from the Wordie Ice Shelf, down Eureka Glacier Eureka Glacier () is a broad, gently sloping glacier, long and wide at its mouth, which flows westward from the west side of Palmer Land into George VI Sound. It is bounded on its north side by the nunataks south of Mount Edgell, on its south s ..., to George VI Sound. Nunataks of Palmer Land {{PalmerLand-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] |
Eureka Glacier
Eureka Glacier () is a broad, gently sloping glacier, long and wide at its mouth, which flows westward from the west side of Palmer Land into George VI Sound. It is bounded on its north side by the nunataks south of Mount Edgell, on its south side by the Traverse Mountains and Terminus Nunatak, and at its head Prospect Glacier provides a route to the Wordie Ice Shelf. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill and resurveyed in 1948 by the Falkland Islands Dependencies Survey. The name, from the ancient Greek word eureka Eureka (often abbreviated as E!, or Σ!) is an intergovernmental organisation for research and development funding and coordination. Eureka is an open platform for international cooperation in innovation. Organisations and companies applying th ..., expresses the triumph of discovery and arose because the BGLE sledge party found their way to George VI Sound via this glacier in 1936. References ...

Riley Glacier
Riley Glacier is a heavily crevassed glacier, 14 nautical miles (26 km) long and 17 nautical miles (31 km) wide, flowing westward from the west side of Palmer Land into George VI Sound between the Traverse Mountains and Mount Dixey. First sighted and surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1949 by the 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 o ... (FIDS) and named for Quintin T.P.M. Riley, assistant meteorologist of the BGLE, 1934–37. The glacier sits at 70° 06' 00.0" S latitude and 67° 55' 00.0" W longitude.

George VI Sound
George VI Sound or Canal Jorge VI or Canal Presidente Sarmiento or Canal Seaver or King George VI Sound or King George the Sixth Sound is a major bay/ fault depression, 300 miles (483 km) long and mainly covered by a permanent ice shelf. It is in the shape of the letter J without any upper bar. It lines the east and south shores of Alexander Island, separating it from the vestigial, quite small, Wordie Ice Shelf and Palmer Land (the south-west of the Antarctic Peninsula) and the north-facing "English Coast". A quite central point of it is . Various lakes adjoin; these receive large amounts of melt ice from the George VI Ice Shelf. These include Hodgson, Moutonee and Ablation Lakes. Several glaciers flow eastward into the sound from the east interior of Alexander Island, the vast majority of these glaciers are south of Planet Heights, where all of these glaciers are named after moons, satellites and planets of the Solar System in the same vein as the Heights, named by the ...

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 ...

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

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] |
Wordie Ice Shelf
The Wordie Ice Shelf () was a confluent glacier projecting as an ice shelf into the SE part of Marguerite Bay between Cape Berteaux and Mount Edgell, along the western coast of Antarctic Peninsula. In March 2008, the British Antarctic Survey reported that it appeared ready to break away from the Antarctic Peninsula. By April 2009 it had done so, vanishing completely. Discovered by the British Graham Land Expedition (BGLE) under Rymill, 1934–37, who named this feature for Sir James Wordie, Honorary Secretary (later President) of the Royal Geographical Society, member of the Discovery Committee, and chairman of the Scott Polar Research Institute. He also had been geologist and Chief of the Scientific Staff of the British expedition, 1914–16, under Ernest Shackleton.
