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 The Fimbul Ice Shelf is an Antarctic ice shelf about long and wide, nourished by Jutulstraumen Glacier, bordering the coast of Queen Maud Land from 3°W to 3°E. It was photographed from the air by the Third German Antarctic Expedition (1938 ..., 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, 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] |

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).

Jelbart Ice Shelf
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 (1949–1952) and named for John E. Jelbart, an Australian observer with the expedition who drowned near Maudheim Station on February 24, 1951.

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 ...

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of 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. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud 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 over a period of 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 on board two whaling ships, the ''Polarsirkel'' and ''Polarbjørn'', on 10 November 1956. The expedition was led by Sigurd Gunnarson Helle, a geodesist at Norsk Polarinstitutt. It included a total crew of fourteen researchers which was reduced to nine during the third year. Among their activities were topological mapping of the region. In 1960, King Olav V of Norway instituted the Antarctic Medal The Antarctic Medal is a civil decoration of Norway. Established by ...

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 ...

Islands Of Queen Maud Land
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The t ...
