Muckle Bluff
Muckle Bluff is a bluff west of Walker Point on the south coast of Elephant Island in the South Shetland Islands of Antarctica. It was mapped by the Joint Services Expedition to Elephant Island, UK Joint Services Expedition, 1970-71. The descriptive name for this prominent feature was applied by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1971; muckle being an old Scottish word meaning large.

Walker Point
Walker Point is a point on the southwest side of the entrance to Gurkovska Cove which lies south-west of Cape Valentine, near the eastern end of Elephant Island in the South Shetland Islands of Antarctica. The name appears on Powell's map of 1822 based upon the joint cruise of Captain Nathaniel B. Palmer, in the sloop ''James Monroe'' with Captain George Powell, in the sloop ''Dove'', in December 1821. It was probably named for Captain John Walker, whose assistance in the construction of the map was acknowledged by Powell. Important Bird Area A 31 ha site comprising all the ice-free ground at a small unnamed point, unofficially referred to as ‘Chinstrap Camp', 2.7 km south-west of Walker Point, has been designated an Important Bird Area (IBA) by BirdLife International BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats. BirdLife International's priorities include preventing extinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephant Island
Elephant Island is an ice-covered, mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. The island is situated north-northeast of the tip of the Antarctic Peninsula, west-southwest of South Georgia, south of the Falkland Islands, and southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the United Kingdom. The Brazilian Antarctic Program maintains a shelter on the island, Goeldi, supporting the work of up to six researchers each during the summer, and formerly had another ( Wiltgen), which was dismantled in the summers of 1997 and 1998. Toponym Elephant Island's name is attributed to both its elephant head-like appearance and the sighting of elephant seals by Captain George Powell in 1821, one of the earliest sightings. However, in Russia it is still known under the name given by its discoverers in 1821 – Mordvinova Island. Geography The island is oriented approximately ...

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] |
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] |
Joint Services Expedition To Elephant Island
The Joint Services Expedition to Elephant Island was a British scientific surveying and mountaineering expedition to Elephant Island in the South Shetland Islands of Antarctica. It took place from December 1970 to March 1971. Except for one civilian from the British Antarctic Survey, the 14 participants were serving members of the British Armed Forces under the leadership of Commander Malcolm Burley of the Royal Navy. The expedition was sponsored by the Joint Services Expedition Trust with the aim of climbing, exploring and carrying out a preliminary scientific survey of islands in the Elephant group for the Directorate of Overseas Surveys The Ordnance Survey International or Ordnance Survey Overseas Directorate its predecessors built an archive of air photography, map and survey records for the United Kingdom from 1946 to 1999. The Ordnance Survey International Collection (formerly .... The expedition was transported to and from the island by HMS ''Endurance''. During the co ...

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. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliffs Of The South Shetland Islands
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
