Composite Gazetteer Of Antarctica
The Composite Gazetteer of Antarctica (CGA) of the Scientific Committee on Antarctic Research (SCAR) is the authoritative international gazetteer containing all Antarctic toponyms published in national gazetteers, plus basic information about those names and the relevant geographical features. The Gazetteer includes also parts of the International Hydrographic Organization (IHO) General Bathymetric Chart of the Oceans (GEBCO) gazetteer for under-sea features situated south of 60° south latitude. , the overall content of the CGA amounts to 37,893 geographic names for 19,803 features including some 500 features with two or more entirely different names, contributed by the following sources: {, class="wikitable sortable" !

Victory Mountains
The Victory Mountains () is a major group of mountains in Victoria Land, Antarctica, about long and wide, which is bounded primarily by Mariner and Tucker glaciers and the Ross Sea. The division between these mountains and the Concord Mountains (to the NW) is less precise but apparently lies in the vicinity of Thomson Peak. A Ross Sea aspect of the mountains was first obtained by early British expeditions of Ross, Borchgrevink, Scott and Shackleton. The mapping of the interior mountains was largely done from air photos taken by the U.S. Navy and surveys undertaken by New Zealand and American parties in the 1950s and 1960s. So named by the NZGSAE 1957-58, because of the proximity of this group to the Admiralty Mountains, and with the intention that many of the topographic features would be named for celebrated victories, especially naval victories.

Rudolph Glacier
Rudolph Glacier is a glacier flowing into Andvord Bay south of Moser Glacier, on the west coast of Graham Land. Charted by the Belgian Antarctic Expedition under Gerlache, 1897–99. Named by the 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 ... (UK-APC) in 1960 for Paul Rudolph, German mathematical optician who designed the first anastigmatic camera lens, introduced by Zeiss in 1889, and the "Tessar" lens, introduced by Zeiss in 1902.

Borchgrevink Coast
The Borchgrevink Coast is that portion of the coast of Victoria Land between Cape Adare and Cape Washington. The name was recommended by New Zealand Antarctic Place-Names Committee in 1961 after Carsten Borchgrevink, a member of Henrik Johan Bull's expedition to this area, 1894–95, and leader of the British Antarctic Expedition, 1898–1900, the first to winter on the continent, at Cape Adare. Landmarks *Agate Peak is a peak situated in the southeast area of the Intention Nunataks, at the southwest margin of Evans Neve within the Borchgrevink Coast. So named by the New Zealand Antarctic Place-Names Committee because agate and other semi-precious stones were found here by the Southern Party of New Zealand Geological Survey Antarctic Expedition, 1966–67.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...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 vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Mariner Glacier
Mariner Glacier is a major glacier over long, descending southeast from the plateau of Victoria Land, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue. Its lower reaches and entrance to its valley were reconnoitered in December 1958 by Captain John Cadwalader, US Navy, and two members of New Zealand Geological Survey Antarctic Expedition (NZGSAE), in a flight from the icebreakers USS ''Glacier'' and USS ''Staten Island'' which were lying close off the south end of Coulman Island Coulman Island is an ice-covered island in the Ross Sea, located southeast of Cape Jones, Victoria Land, Antarctica. It is long, wide and in elevation. Emperor penguins inhabit this island. It was discovered in 1841 by Sir James Clark Ross ..., in an attempt to land expedition members on the mainland. Named by NZGSAE, 1958–59, as a tribute to the work of mariners in Antarctic research and explorati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
