Sørsdal Glacier
Sørsdal Glacier () is a heavily crevassed glacier on the Ingrid Christensen Coast of Princess Elizabeth Land in Antarctica, long, flowing westward along the south side of Krok Fjord and the Vestfold Hills and terminating in a prominent glacier tongue at Prydz Bay. Discovered in February 1935 by a Norwegian expedition under Captain Klarius Mikkelsen and named for Lief Sørsdal, a Norwegian dentist and a member of the party from the whaling ship ''Thorshavn'' that landed at the northern end of the Vestfold Hills. The Sørsdal Glacier Tongue () is the prominent seaward extension of Sørsdal Glacier into Prydz Bay.

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] |
Crevasse
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by |
Princess Elizabeth Land
Princess Elizabeth Land is the sector of Antarctica between longitude 73° east and Cape Penck (at 87°43' east). The sector is claimed by Australia as part of the Australian Antarctic Territory, although this claim is not widely recognized. Geography Princess Elizabeth Land is located between 64°56'S and 90°00'S and between 73°35' E and 87°43'E. It is divided into two sectors: * Ingrid Christensen Coast, 73°35'E to 81°24'E * Leopold and Astrid Coast, 81°24'E to 87°43'E It is bounded on the west by Amery Ice Shelf, Mac. Robertson Land, and on the east by Kaiser Wilhelm II Land. Exploration Princess Elizabeth Land was discovered on 9 February 1931, by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) (1929–31) under Sir Douglas Mawson. Princess Elizabeth Land was named by Mawson after Princess Elizabeth, granddaughter of King George V who reigned at the time as King of Australia, among his other titles. Princess Elizabeth would later g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prydz Bay
Prydz Bay is a deep embayment of Antarctica between the Lars Christensen Coast and Ingrid Christensen Coast. The Bay is at the downstream end of a giant glacial drainage system that originates in the East Antarctic interior. The Lambert Glacier flows from Lambert Graben into the Amery Ice Shelf on the south-west side of Prydz Bay. Other major glaciers drain into the southern end of the Amery Ice Shelf at 73° S where the marine part of the system starts at the modern grounding zone. The Amery Ice Shelf extends about 550 km north of the Lambert Glacier grounding zone and occupies a valley between 80 and 200 km wide. Depths to the bed beneath the Amery Ice Shelf are poorly known in detail but it is clearly over-deepened, reaching around -2500 m MSL close to the grounding zone. The Amery Ice Shelf occupies a very large U-shaped valley with exposed nunataks along the flanks reaching 1500 m in elevation and total relief as high as 3000 m. Seaward of the Amery Ice Shelf ...

NASA Landsat SorsdalGlacier Bands432
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...

Ingrid Christensen Coast
The Ingrid Christensen Coast is that portion of the coast of Antarctica lying between Jennings Promontory, in 72°33′E, and the western end of the West Ice Shelf in 81°24′E. It is located in the western half of Princess Elizabeth Land, just east of the Amery Ice Shelf. Exploration The coast was discovered and a landing made on the Vestfold Hills on February 20, 1935, by Captain Klarius Mikkelsen in the ''Tórshavn'', a vessel owned by Norwegian whaling magnate Lars Christensen Lars Christensen (6 April 1884 – 10 December 1965) was a Norwegian shipowner and whaling magnate. He was also a philanthropist with a keen interest in the exploration of Antarctica. Career Lars Christensen was born at Sandar in Vestfold, No .... It was named for Ingrid Christensen, wife of Lars, who sailed in Antarctic waters with her husband, and was one of the first women to visit Antarctica.

Vestfold Hills
The Vestfold Hills are rounded, rocky, coastal hills, in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between in height, with the highest summit reaching nearly . Geography The Vestfold Hills are largely snow and ice-free and are thus classified as an Antarctic oasis. They contain a great variety of lake systems with over 300 lakes and ponds including what is possibly the largest concentration of meromictic (stratified) lakes in the world. This region contains 37 permanently stratified water bodies, including six marine basins and seven seasonally isolated marine basins (SIMBs). These stratified basins also have great variety. They range in salinity from 4 g L−1 to 235 g L−1, in temperature from , in depth from , in area from and surface level from below to above sea level. The region contains ...

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 ...
