Leppard Glacier
Leppard Glacier () is a large valley glacier draining east between the Aristotle Mountains and Voden Heights, and flowing into Scar Inlet north of Ishmael Peak, on the east coast of Graham Land, Antarctica. The glacier was first seen from the air and photographed in part by Hubert Wilkins on December 20, 1928, and was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955. It is now clear that, on the photographic evidence of his outward flight, Wilkins gave the name "Crane Channel" to this glacier, and that on his return flight he photographed what is now accepted as Crane Glacier, perhaps thinking that it was the same feature. Since Crane Glacier has been retained for the northern of these glaciers photographed by Wilkins, the UK Antarctic Place-Names Committee has named this feature for Norman A.G. Leppard, assistant surveyor with the FIDS, who surveyed this area in 1955. See also * List of glaciers in the Antarctic There are many glaciers in the Antarctic. ...

Valley Glacier
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. ...

Aristotle Mountains
Aristotle Mountains is the fan-shaped sequence of ridges spreading east-northeastwards from its summit Madrid Dome (1647 m) on Oscar II Coast in Graham Land on the Antarctic Peninsula. The feature is named after the ancient Greek scientist Aristotle who in his book ''Meteorology'' dated c. 350 BC was the first to conjecture the existence of a landmass in the southern high-latitude region, calling it ''Antarctica''.Aristotle Mountains.

Voden Heights
Voden Heights ( bg, Воденски възвишения, ‘Vodenski Vazvisheniya’ \'vo-den-ski v&z-vi-'she-ni-ya\) are the heights extending 42.5 km in the east-west direction and 15.4 km wide, rising to 1700 m ( Mount Zadruga) on Oscar II Coast in Graham Land. They are bounded by Flask Glacier to the north, Scar Inlet to the east, Leppard Glacier to the south and its tributary Fleece Glacier to the southwest, and linked by a wide ice-covered saddle to Bruce Plateau to the west.

Scar Inlet
The calving front at the Scar Inlet The Scar Inlet is an area of the Larsen Ice Shelf immediately northwest of Jason Peninsula, named after the Scientific Committee on Antarctic Research. It is bounded by Tashtego Point and Chapman Point. History The region was discovered in 1902 by Otto Nordenskjold, leader of the Swedish Antarctic Expedition, 1901–04, who gave the name "Scott Bay". The name did not survived in usage, perhaps due to the large number of features already named after Captain Robert F. Scott. The present name was given in 1963 by the United Kingdom Antarctic Place-Names Committee (UK-APC) after the Scientific Committee on Antarctic Research of the International Council of Scientific Unions, in recognition of the role of this organization in furthering scientific research in the Antarctic. It is the remaining fragment of the much larger Larsen B The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of ...

Ishmael Peak
Ishmael Peak () is a conspicuous detached rock peak in eastern Voden Heights, south of Spouter Peak, which marks the north side of the mouth of Leppard Glacier, on the east coast of Graham Land, Antarctica. It was surveyed by the Falkland Islands Dependencies Survey in 1947 and 1955, and was named by the UK Antarctic Place-Names Committee after Ishmael, the narrator of Herman Melville Herman Melville (Name change, born Melvill; August 1, 1819 – September 28, 1891) was an American people, American novelist, short story writer, and poet of the American Renaissance (literature), American Renaissance period.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, 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 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

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 vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Wilkins
Sir George Hubert Wilkins MC & Bar (31 October 188830 November 1958), commonly referred to as Captain Wilkins, was an Australian polar explorer, ornithologist, pilot, soldier, geographer and photographer. He was awarded the Military Cross after he assumed command of a group of American soldiers who had lost their officers during the Battle of the Hindenburg Line, and became the only official Australian photographer from any war to receive a combat medal. He narrowly failed in an attempt to be the first to cross under the North Pole in a submarine, but was able to prove that submarines were capable of operating beneath the polar ice cap, thereby paving the way for future successful missions. The US Navy later took his ashes to the North Pole aboard the submarine USS ''Skate'' on 17 March 1959. Early life Hubert Wilkins was a native of Mount Bryan East, South Australia, the last of 13 children in a family of pioneer settlers and sheep farmers. He was born at Mount Bryan East, ...

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] |
Crane Glacier
Crane Glacier (), is a narrow glacier which flows in an east-northeasterly direction along the northwest side of Aristotle Mountains to enter Spillane Fjord south of Devetaki Peak, on the east coast of the Antarctic Peninsula. Sir Hubert Wilkins photographed this feature from the air in 1928 and gave it the name "Crane Channel", after C.K. Crane of Los Angeles, reporting that it appeared to be a channel cutting in an east-west direction across the peninsula. The name was altered to "Crane Inlet" following explorations along the west coast of the peninsula in 1936 by the British Graham Land Expedition, which proved that no through channel from the east coast existed as indicated by Wilkins. Comparison of Wilkins' photograph of this feature with those taken in 1947 by the Falklands Islands Dependencies Survey shows that Wilkins' "Crane Channel" is this glacier, although it lies about northeast of the position originally reported by Wilkins. The speed of Crane Glacier increas ... [...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 Scientific Committee on Antarctic Research, 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.
