Blåskimen Island
Blåskimen Island is a high, ice-covered island about north of Novyy Island, at the juncture of the Jelbart Ice Shelf and the Fimbul Ice Shelf, Queen Maud Land. The island rises about above the general level of the ice shelf and is surrounded by this ice, except for the north side which borders the sea. The feature was roughly delineated by Norwegian cartographers working with air photos taken by the Norwegian–British–Swedish Antarctic Expedition in 1951–52 and the Sixth Norwegian Antarctic Expedition in 1958–59. They called the island Blåskimen and included the area now called Novyy Island. The Soviet Antarctic Expedition mapped the feature in 1961 and showed it to be separated from Novyy Island.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Antarctic Treaty System
The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, designating the continent as a scientific preserve, establishing freedom of scientific investigation, and banning Military activity in the Antarctic, military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude. Since September 2004, the Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in Buenos Aires, Argentina. The main treaty was opened for signature on 1 December 1959, and officially coming into force, entered into force on 23 June 1961. The original signatories were the 12 countries active in Antarctica during the International Geophysical Year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novyy Island
Novyy Island is the larger and southern island of two similar ice covered features that serve to delimit the Jelbart and Fimbul Ice Shelves, on the coast of Queen Maud Land. The summit of this feature rises about 250 m above the surrounding ice shelf. The island was partly delineated by the Norwegian Antarctic Expedition, 1956–60. It was mapped by the Soviet Antarctic Expedition in 1961 and named "Kupol Novyy" (new dome).

The Jelbart Ice Shelf is an ice shelf about wide, fronting on the coast of Queen Maud Land, Antarctica, northward of Giaever Ridge. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition The Norwegian–British–Swedish Antarctic Expedition (also known as NBSX or NBSAE) (1949–1952) was the first Antarctica expedition involving an international team of scientists.

Queen Maud Land
Queen Maud Land () is a roughly region of Antarctica Territorial claims in Antarctica, claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20th meridian west, 20° west, specifically the Caird Coast, Coats Land on the West, and the Australian Antarctic Territory 45th meridian east, 45° east, specifically Enderby Land on the 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 Maud of Wales, Queen Maud (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 dependencies of Norway, two Antarctic claims made by Norway, the other being Peter I Island. They are adm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Shelf
An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers. Ice shelves form along coastlines where the ice thickness is insufficient to displace the more dense surrounding ocean water. The boundary between the ice shelf (floating) and grounded ice (resting on bedrock or sediment) is referred to as the grounding line; the boundary between the ice shelf and the open ocean (often covered by sea ice) is the ice front or calving front. Ice shelves are found in Antarctica and the Arctic (Greenland, Northern Canada, and the Russian Arctic), and can range in thickness from about . The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. Typically, a shelf front will extend forward for years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian–British–Swedish Antarctic Expedition
The Norwegian–British–Swedish Antarctic Expedition (also known as NBSX or NBSAE) (1949–1952) was the first Antarctica expedition involving an international team of scientists. The team members came from Norway, Sweden and the British Commonwealth of Nations. History The Norwegian–British–Swedish Antarctic Expedition was the first expedition to Antarctica involving an international team of scientists. The expedition was led by John Schjelderup Giæver, a Norwegian author and polar researcher. The expedition had the goal of establishing whether climatic fluctuations observed in the Arctic were also occurring in the Antarctic. A base known as Maudheim was established on the Quar Ice Shelf along the coast of Queen Maud Land in February 1950. This expedition laid the groundwork for the following Australian expeditions to Antarctic from 1954 to the early 1960s. Transportation The expedition was transported aboard a 600-ton sealer named that was powered by a German U-boat d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud's Land in Antarctica. The expedition was based at Norway Station () which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land. The expedition carried out survey work and scientific studies for three-four years (1956–1960). The expedition was intended as part of Norway's participation in the International Geophysical Year, 1957-58. The crew set sail from Oslo Oslo ( or ; ) is the capital and most populous city of Norway. It constitutes both a county and a municipality.

Soviet Antarctic Expedition
The Soviet Antarctic Expedition (SAE or SovAE) (, ''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. It was succeeded by the Russian Antarctic Expedition. 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. In December 1957 another station, '' Vostok,'' was built inland near the South geomagnetic pole.
