Wright Lower Glacier
Wright Lower Glacier () is a stagnant glacier occupying the mouth of Wright Valley and coalescing at its east side with Wilson Piedmont Glacier, in Victoria Land, Antarctica. The glacier was originally called "Wright Glacier" by the British Antarctic Expedition (1910–13), for expedition member C.S. Wright. The name was adjusted decades later by the Victoria University of Wellington Antarctic Expedition The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Valley
The Wright Valley, named for Sir Charles Wright, is the central one of the three large Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound at approximately . Wright Valley contains the Onyx River, the longest river in Antarctica, Lake Brownworth, the origin of the Onyx River, and Lake Vanda, which is fed by the Onyx River. Its southwestern branch, ''South Fork'', is the location of Don Juan Pond. The upland area known as the Labyrinth is at the valley's west end. Although portions of the interconnected valley system were discovered in 1903 by the ''Discovery'' expedition led by Captain Robert Falcon Scott, the Wright Valley located near the centre of the system was not seen until aerial photographs of the region were made in 1947. By the mid 1960s scientists were becoming increasingly intrigued by the paradoxical fact that the valley lay immediately adjacent to the permanent East Antarctic Ice Sheet, yet had remained ice-free for at least thousand ...

Wilson Piedmont Glacier
Wilson Piedmont Glacier () is a large piedmont glacier extending from Granite Harbour to Marble Point on the coast of Victoria Land. Scheuren Stream takes meltwater from the glacier into the Bay of Sails, while South Stream flows southeastward to Bernacchi Bay. Discovered by the ''Discovery'' expedition, 1901–04. The British Antarctic Expedition, 1910–13, named the feature for Dr. Edward A. Wilson, surgeon and artist with Scott's first expedition and chief of the scientific staff with the second. Wilson lost his life on the way back from the South Pole The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipod ... with Scott. See also * Ball Stream * King Pin Glaciers of Scott Coast {{ScottCoast-glacier-stub ...

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 Al ... [...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] |
Terra Nova Expedition
The ''Terra Nova'' Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. Led by Captain Robert Falcon Scott, the expedition had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the ''Discovery'' Expedition from 1901 to 1904, and wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that a Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's party of five died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later. The expedition, named after its supply ship, was a private venture financed by public contributions and a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria University Of Wellington Antarctic Expedition
The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research " Antarctic climate history and processes, and their influence on the global climate system. The current director of the Antarctic Research Centre is Associate Professor Robert McKay. Directors * 1972 - 2007: Professor Peter Barrett * 2008 - 2016: Professor Tim Naish * 2017 - 2019: Professor Andrew Mackintosh * 2020 - Present: Professor Robert McKay History In December 1957, geology students Barrie McKelvey and Peter Webb along with biologist Ron Balham conducted an expedition to the then unexplored McMurdo Dry Valleys via the Royal New Zealand Navy Antarctic support ship HMNZS ''Endeavour''. This expedition formed the basic for the annual Victoria University of Wellington Antarctic Expeditions, which continue to the present day. Since this first expedition, over 400 staff and students have travelled to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Upper Glacier
Wright Upper Glacier () is an ice apron at the upper west end of Wright Valley in Asgard Range, Antarctica. It is formed by a glacier flowing east from the inland ice plateau. Named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) for C.S. Wright, a member of the British Antarctic Expedition (1910–13), after whom the "Wright Glacier" (adjusted to Wright Lower Glacier by the VUWAE) was named. Two massive icefalls descend from the plateau into the Wright Upper Glacier, the wide and tall Airdevronsix Icefalls and the equally tall wide Warren Icefalls, which was named by the Advisory Committee on Antarctic Names (US-ACAN) in 2004 for Alden Warren, a longtime photographer (scientific and technical) with the United States Geological Survey, involved in documenting maps of Antarctica. Vortex Col is a col leading from the plateau into the south side of the glacier. At this locality, winds carrying clouds of snow from the polar plateau are deflect ...
