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] |
Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Lomonosov Mountains
The Lomonosov Mountains () are a somewhat isolated chain of mountains extending northeast–southwest, located east of the Wohlthat Mountains in Queen Maud Land, Antarctica. They were discovered and first plotted from air photos by the Third German Antarctic Expedition, 1938–39, and were mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1958–59. The mountains were remapped by the Soviet Antarctic Expedition The Soviet Antarctic Expedition (SAE or SovAE) (russian: Советская антарктическая экспедиция, САЭ, ''Sovetskaya antarkticheskaya ekspeditsiya'') was part of the Arctic and Antarctic Research Institute of the S ..., 1960–61, and named after Russian scientist Mikhail Lomonosov.

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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.

Wohlthat Mountains
Wohlthat Mountains (german: Wohlthatmassiv) is a large group of associated mountain features consisting of the Humboldt Mountains, Petermann Ranges, and the Gruber Mountains, located immediately east of the Orvin Mountains in Fimbulheimen in the central Queen Maud Land. Discovered by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher, and named for Councilor of state Helmuth C.H. Wohlthat, who as economist and fiscal officer dealt with the organization of the expedition. The area was reconnoitered and aerially photographed by the 5th Indian Antarctic Expedition (Nov 1985-Mar 1986) with a three-month temporary summer camp established there. The area was revisited by later Indian Antarctic expeditions. Astor Rocks The Astor Rocks () are two small rock outcrops lying southeast of Mount Ramenskiy in the southeast extremity of the Wohlthat Mountains. They were plotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition (NorAE) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Swabia
New Swabia (Norwegian and german: Neuschwabenland) was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, , itself named after the German region of Swabia.McGonigal, David, Antarctica', frances lincoln ltd, 2009, , p. 367 Background Like many other countries, Germany sent expeditions to the Antarctic region in the late 19th and early 20th centuries, most of which were scientific. The late 19th century expeditions to the Southern Ocean, South Georgia, the Kerguelen Islands, and the Crozet Islands were astronomical, meteorological, and hydrological, mostly in close collaboration with scientific teams from other countries. As the 19th century ended, Germany began to focus on Antarctica. The first German expedition to Antarctica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Antarctic Expedition
The Soviet Antarctic Expedition (SAE or SovAE) (russian: Советская антарктическая экспедиция, САЭ, ''Sovetskaya antarkticheskaya ekspeditsiya'') was part of the Arctic and Antarctic Research Institute of the Soviet Committee on Antarctic Research of the Academy of Sciences of the USSR. The Soviet Union's Ministry of Sea Transport was responsible for the administration, logistics and supply of the expeditions. The first Soviet contact with Antarctica was in January 1947 when the Slava whaling flotilla began whaling in Antarctic waters. Stations The first Soviet Antarctic station, '' Mirny'', was established near the coast on February 13, 1956. This was added to in December 1957 by another station, ''Vostok'' built inland near the south geomagnetic pole. Year-round stations * Mirny (established February 13, 1956) * Vostok (established December 16, 1957) * Novolazarevskaya (established January 18, 1961) * Molodyozhnaya (established January 1 ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...
