Icefall
An icefall is a portion of certain glaciers characterized by relatively rapid flow and chaotic crevassed surface, caused in part by gravity. The term ''icefall'' is formed by analogy with the word ''waterfall'', which is a similar phenomenon of the liquid phase but at a more spectacular speed. When ice movement of a glacier is faster than elsewhere, because the glacier bed steepens or narrows, and the flow cannot be accommodated by plastic deformation, the ice fractures, forming crevasses. Where two fractures meet, seracs (or ice towers) can be formed. When the movement of the ice slows down, the crevasses can coalesce, resulting in the surface of the glacier becoming smoother. Ice flow Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows. Most glacier ice flows at speeds of a few hundred metres per year or less. However, the flow of ice in an icefall may be measured in kilometres per year. Such rapid flow cannot ...

Visca Anchorage
Martel Inlet () is an inlet forming the northeast head of Admiralty Bay, King George Island, in the South Shetland Islands off Antarctica. The inlet and most of its constituent features were charted in December 1909 by the Fourth French Antarctic Expedition under Jean-Baptiste Charcot and named "Fiord Martel" after J.L. Martel, a French politician. The mountain ridge Ullmann Spur is located at the head of the inlet. Visca Anchorage is the northwestern cove of Martel Inlet. It was named by Charcot for an acquaintance in Montevideo. Within the cove is Sea Leopard Patch, a shoal with a least depth of . It was charted in 1927 by Discovery Investigations personnel on the Discovery and named after the leopard seal, ''Hydrurga leptonyx''.

King George Island (Antarctica)
King George Island ( Argentinian Spanish: Isla 25 de Mayo, Chilean Spanish: Isla Rey Jorge, Russian: Ватерло́о Vaterloo) is the largest of the South Shetland Islands, lying off the coast of Antarctica in the Southern Ocean. The island was named after King George III. Geography King George island has three major bays, Maxwell Bay, Admiralty Bay, and King George Bay. Admiralty Bay contains three fjords, and is protected as an Antarctic Specially Managed Area under the Protocol on Environmental Protection to the Antarctic Treaty. History The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines ''Isla Veinticinco de Mayo'' (25 May) i ...

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Antarctic Expedition
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
