Pollux Nunatak
Pollux Nunatak () is one of the Seal Nunataks, lying 2 nautical miles (3.7 km) northwest of Robertson Island in Larsen Ice Shelf. The probable existence of the feature was first reported by Falkland Islands Dependencies Survey (FIDS) in 1947 and its existence was confirmed during a FIDS survey in 1953. The United Kingdom Antarctic Place-Names Committee (UK-APC) name derives from its association with Castor Nunatak Castor Nunatak () is a nunatak southwest of Oceana Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was first seen and mapped as an island in December 1893 by a Norwegian Sealing expedition under C.A. Larsen, ... 4.5 nautical miles (8 km) to the SSW; Castor and Pollux were sons of Zeus.

Seal Nunataks
The Seal Nunataks are a group of 16 islands called nunataks emerging from the Larsen Ice Shelf east of Graham Land, Antarctic Peninsula. The Seal Nunataks have been described as separate volcanic vents of ages ranging from Miocene to Pleistocene. There are unconfirmed reports of Holocene volcanic activity. Geography and geomorphology The Seal Nunataks are part of Graham Land and were embedded within the Larsen Ice Shelf until its northern margin collapsed between 1986 and 1996, rising from about below sea level. They were discovered by the Norwegian Carl Anton Larsen in December 1893, who also identified them as volcanoes and named them ''Seal Islands''. The Argentina Base Aérea Teniente Benjamín Matienzo is located in the Seal Nunataks. The Seal Nunataks are part of a volcanic province in West Antarctica which extends over the Antarctic Peninsula, Marie Byrd Land and Ross Island. In the Antarctic Peninsula, Alexander Island, James Ross Island and the Seal Nunataks f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robertson Island
Robertson Island is an ice-covered island, long in a northwest-southeast direction and wide, lying at the east end of the Seal Nunataks off the east coast of the Antarctic Peninsula. Captain Carl Anton Larsen discovered Robertson Island from the ''Jason'' on 9 December 1893. Curious to find out if the volcano was active he skied to the top from the north side of the island, later naming it Mt. Christensen after his longtime partner and majority owner of the ''Jason'', Christen Christensen. Larsen named Robertson Island for William Robertson, co-owner of the Hamburg-based company Woltereck and Robertson. San Roque Refuge San Roque Refuge () was an Argentine Antarctic refuge located on Robertson Island at the east end of the Foca nunataks off the Nordenskjöld coast east of the Antarctic Peninsula. The shelter was opened on 1 October 1956, and was administered by the Argentine Army. The refuge had been occupied and used in various operations and currently is inactive. It is ...

Larsen Ice Shelf
The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula from Cape Longing to Smith Peninsula. It is named after Captain Carl Anton Larsen, the master of the Norwegian whaling vessel ''Jason'', who sailed along the ice front as far as 68°10' South during December 1893. In finer detail, the Larsen Ice Shelf is a series of shelves that occupy (or occupied) distinct embayments along the coast. From north to south, the segments are called Larsen A (the smallest), Larsen B, and Larsen C (the largest) by researchers who work in the area. Further south, Larsen D and the much smaller Larsen E, F and G are also named. The breakup of the ice shelf since the mid-1990s has been widely reported, with the collapse of Larsen B in 2002 being particularly dramatic. A large section of the Larsen C shelf broke away in July 2017 to form an iceberg known as A-68. The ice shelf originally covered an area of , but ...

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.

United Kingdom 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 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 features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castor Nunatak
Castor Nunatak () is a nunatak southwest of Oceana Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was first seen and mapped as an island in December 1893 by a Norwegian Sealing expedition under C.A. Larsen, who named it after the ''Castor'', a ship which combined sealing and exploring activities along the west coast of the Antarctic Peninsula under Captain Morten Pedersen in 1893–94. The feature was determined to be a nunatak in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants ''Audo'', '' Odo'', ''Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded f ....

Nunataks Of Graham Land
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] |
