Allen Knoll
Allen Knoll () is a steep-sided snow dome rising from a flat snowfield northwest of the head of Russell West Glacier, Trinity Peninsula, Antarctica. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61) and named by the UK Antarctic Place-Names Committee for Keith Allen, a FIDS radio operator at Hope Bay Hope Bay ( Spanish: ''Bahía Esperanza'') on Trinity Peninsula, is long and wide, indenting the tip of the Antarctic Peninsula and opening on Antarctic Sound. It is the site of the Argentinian Antarctic settlement Esperanza Base, established ... in 1959 and 1960. References Mountains of Trinity Peninsula {{TrinityPeninsula-geo-stub ...

Snowfield
A snow field, snowfield or neve is an accumulation of permanent snow and ice, typically found above the snow line, normally in mountainous and glacial terrain. Glaciers originate in snowfields. The lower end of a glacier is usually free from snow and névé in summer. In the upper end and above the upper boundary of a glacier, the snow field is an ice field An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and highe ... covered with snow. The glacier upper boundary, where it emerges from under a snow field, is ill-defined because of gradual transition.Thomas Chrowder Chamberlin, Rollin D.

Russell West Glacier
Russell West Glacier () is a glacier, 11 nautical miles (20 km) long and 4 nautical miles (7 km) wide, which lies immediately north of Detroit Plateau and flows from Mount Canicula, Verdikal Gap and Trajan Gate westward into Bone Bay on the north side of Trinity Peninsula. This glacier together with Russell East Glacier, which flows eastward into Prince Gustav Channel on the south side of Trinity Peninsula, form a through glacier across the north part of Antarctic Peninsula. It was first surveyed in 1946 by the Falkland Islands Dependencies Survey (FIDS). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for V.I. Russell, surveyor and leader of the FIDS base at Hope Bay in 1946.

Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, alth ...

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 ve ... [...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 British Admiralty, Admiralty and the Secretary of ... [...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 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. Anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hope Bay
Hope Bay ( Spanish: ''Bahía Esperanza'') on Trinity Peninsula, is long and wide, indenting the tip of the Antarctic Peninsula and opening on Antarctic Sound. It is the site of the Argentinian Antarctic settlement Esperanza Base, established in 1952. Important Bird Area The bay has been identified as an Important Bird Area (IBA) by BirdLife International because it supports one of the largest Adélie penguin colonies in Antarctica with around 125,000 pairs. Other birds nesting at the site include gentoo penguins, brown skuas, Antarctic terns, Wilson's storm-petrels, kelp gulls and snowy sheathbills. History The Bay was discovered on January 15, 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it in commemoration of the winter spent there by J. Gunnar Andersson and S.A. Duse, Toralf Grunden of his expedition after his ship (the ''Antarctic'') was crushed by the ice and lost. They were eventually rescued by Argentine corvette ''Uruguay''. H ...
