Antarctic Oasis
An Antarctic oasis is a large area naturally free of snow and ice in the otherwise ice-covered continent of Antarctica. Geology In Antarctica there are, in addition to mountaintops and nunataks, other natural snow- and ice-free areas often referred to as "Antarctic oases" or "dry valleys".http://iopscience.iop.org/1755-1315/1/1/012035/pdf/ees8_1_012035.pdf, IOP science, accessdate=2010-11-22 Bernadette Hince, "The Antarctic dictionary: a complete guide to Antarctic English", 2000, Csiro Publishing, Collingwood, Australia, , accessdate=2010-11-22 These areas are surrounded by the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Valley From Bull Pass
Wright is an occupational surname originating in England. The term 'Wright' comes from the circa 700 AD Old English word 'wryhta' or 'wyrhta', meaning worker or shaper of wood. Later it became any occupational worker (for example, a shipwright is a person who builds ships), and is used as a British family name. The word's use as an occupational title continued until the mid-19th century, often combined with other words such as in shipwright, wheelwright, Wainwright (occupation), wainwright and playwright. '', Wright'' was the eleventh most common surname in England. The word Carpenter (surname), ''carpentier'', now "carpenter", was introduced into England in the years after the Norman conquest of England, Norman conquest in 1066 and slowly replaced the traditional name and meaning of wright in most of England. 'Wright' is still used in Scottish English in the original meaning of 'skilled woodworker'. The Incorporation of Wrights of the Trades House of Glasgow, and the Incorporati ...

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys Antarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princess Astrid Coast
Princess Astrid Coast is a portion of the coast of Queen Maud Land, Antarctica, lying between 5° and 20° E. The entire coast is bordered by ice shelves. The region was discovered by Capt. H. Halvorsen of the Sevilla (ship) in March 1931 and in 1932 was named for Princess Astrid of Norway. The ice of the continental glacier, which is up to 4,000 meters thick in the interior. These thick glaciers are held in place by coastal mountain ranges. On the Princess Astrid Coast, some of the ice does flow through the mountains, spilling onto the relatively flat land on the Princess Astrid Coast. Also, the cold air spills over the mountains, creating very strong and persistent winds, which makes the snow scour off the tops of the glaciers leaving pale blue patches of bare ice. On top of the coastal line is the ice shelf, which is much smoother. The glacial ice floats on the sea surface which is beyond the chaotic surface of the sea ice which has been solidifying all winter long. Off the Pr ...

Schirmacher Oasis
The Schirmacher Oasis (or Schirmacher Lake Plateau) is a long and up to wide ice-free plateau with more than 100 freshwater lakes. It is situated in the Schirmacher Hills on the Princess Astrid Coast in Queen Maud Land in East Antarctica and is, on average, above sea level. With an area of , the Schirmacher Oasis ranks among the smallest Antarctic oases and is a typical polar desert. Geography The oasis is located between the edge of the Antarctic Ice Sheet and the ''Novolazarevskaya Nivl Ice Shelf''. The approximately high plateau of the Schirmacher Oasis is a barrier to the northwards-running ice stream. On the northern edge of the oasis are so-called epishelf lakes, bays separated from the ocean which are connected with the ocean underneath the surface of the ice. Thus, tidal effects can be observed in the lakes. The epishelf lakes can contain either mere freshwater or saltwater which is overlaid by freshwater. The Antarctic Ice Sheet, southwards of the Schirmacher Oasis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kemp Land
Kemp Land is a thin sliver of Antarctica including, and lying inland from, the Kemp Coast. Part of the Australian Antarctic Territory, Australian Antarctic claim it is defined as lying between 56° 25' E and 59° 34' E, and, as with other sectors of the Antarctic, is deemed being limited by the 60° S parallel. It is bounded in the east by Mac. Robertson Land and in the west by Enderby Land. Kemp Land includes one major group of islands, the Øygarden Group.Kemp Land on Scientific Committee on Antarctic Research, SCAR website It reaches a height of 3,346 feet above sea level.

Stillwell Hills
Stillwell Hills is a group of largely snow-free rocky hills composed of banded gneisses and including Kemp Peak and Lealand Bluff, extending along the southwest side of William Scoresby Bay. This area was explored by Discovery Investigations personnel on the ''RSS William Scoresby'' in February 1936, and by the Lars Christensen Expedition, 1936–37, the latter group taking air photos used to map these hills for the first time. Geologic investigation of the area was made by Australian National Antarctic Research Expeditions (ANARE) in 1961. Named by ANCA for Dr. Frank Leslie Stillwell, geologist with Australasian Antarctic Expedition (AAE), 1911–14, who derived a theory of metamorphic differentiation from banded gneisses of the same type on George V Coast George V Coast () is that portion of the coast of Antarctica lying between Point Alden, at 148°2′E, and Cape Hudson, at 153°45′E. Portions of this coast were sighted by the US Exploring Expedition in 1840. It was e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larsemann Hills
The Larsemann Hills are a series of low rounded coastal hills along the southeastern shore of Prydz Bay, Antarctica extending for from Dålk Glacier. They were discovered in February 1935 by Captain Klarius Mikkelsen from the whaling ship ''Thorshavn'', sent out by Norwegian whaling magnate Lars Christensen, and given this name. The bedrock of the Larsemann Hills contains an unusually high abundance of boron and phosphate minerals and is the location of discovery of four new species of mineral. In 2014, the Stornes Peninsula within the Larsemann Hills was declared an Antarctic Specially Protected Area due to its mineral diversity. Research stations As an Antarctic oasis the hills are the home of several Antarctic research stations. * The abandoned original Russian Progress Station. * The relocated new Russian Progress II Station. * The Chinese Zhongshan station * The Australian-donated Romanian Law-Racoviță-Negoiță Station * The India India, officially the Republi ...
