Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

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] |
New Zealand Antarctic Research Program
The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Industrial Research (DSIR), originally based in Wellington. The programme promoted research in geochemistry, zoology, geology, botany, meteorology, and limnology. History NZARP began as a proposal by the New Zealand government, in 1953, for a research base in Antarctica. Its mission was to provide support for a variety of scientific fieldwork in Antarctica. Members worked as researchers, assistants, tour guides, operators, and administrators to Scott Base. Ground was broken for Scott Base on 10 January 1957. Assembly of the base began 12 January, conducted by the eight men who first assembled the base in Wellington, and was completed by 20 January. In 1959, the NZARP was established to work with the Ross Dependency Research Committee in the Ros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennell Coast
Pennell Coast is that portion of the coast of Antarctica between Cape Williams and Cape Adare. To the west of Cape Williams lies Oates Coast, and to the east and south of Cape Adare lies Borchgrevink Coast. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Lieutenant Harry Pennell, Royal Navy, commander of the Terra Nova, the expedition ship of the British Antarctic Expedition, 1910–13. Pennell engaged in oceanographic work in the Ross Sea during this period. In February 1911 he sailed along this coast in exploration and an endeavor to land the Northern Party led by Lieutenant Victor Campbell. The name is also used more loosely to refer to both the coast itself and the hinterland extending south to the watershed of the Southern Cross Mountains to the southeast and the Usarp Mountains to the west. Major features of the coast include the 250-kilometer long Rennick Glacier (one of Antarctica's largest glaciers), the Anare Mountains, and the norther ...

Cape Adare
Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica. Description Marking the north end of Borchgrevink Coast and the west end of Pennell Coast, the cape separates the Ross Sea to the east from the Southern Ocean to the west, and is backed by the high Admiralty Mountains. Cape Adare was an important landing site and base camp during early Antarctic exploration. Off the coast to the northeast are the Adare Seamounts and the Adare Trough. History Captain James Ross discovered Cape Adare in January 1841 and named it after his friend the Viscount Adare (the title is derived from Adare, Ireland). In January 1895, Norwegian explorers Henrik Bull and Carsten Borchgrevink from the ship '' Antarctic'' landed at Cape Adare as the first documented landing on Antarctica, collecting geological specimens. Borchgrevink returned to the cape leading his own expedition i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
