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 ...

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] |
Cirque
A (; from the Latin word ) is an amphitheatre-like valley formed by Glacier#Erosion, glacial erosion. Alternative names for this landform are corrie (from , meaning a pot or cauldron) and ; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepening, overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (lake), tarn (small lake) behind a d ...

Humboldt Mountains (Antarctica)
The Humboldt Mountains () are a group of mountains immediately west of the Petermann Ranges (Antarctica), Petermann Ranges, forming the westernmost portion of the Wohlthat Mountains in Queen Maud Land, Antarctica. Discovery and naming The mountains were discovered and mapped by the Third German Antarctic Expedition (1938–1939), led by Alfred Ritscher, who named them for Alexander von Humboldt, famed German naturalist and geographer of the first half of the nineteenth century. Historic monument A Commemorative plaque, plaque was erected at India Point () in the Humboldt Mountains in memory of three scientists of the Geological Survey of India, as well as a communications technician from the Indian Navy, all of whom were members of the ninth Indian Expedition to Antarctica, who died in an accident at the site on 8 January 1990. The plaque has been designated a Historic Sites and Monuments in Antarctica, Historic Site or Monument (HSM 78), following a proposal by India to the Antar ...

German Antarctic Expedition (1938–1939)
The German Antarctic Expedition of 1938–1939 was led by ''Kriegsmarine'' captain Alfred Ritscher (1879–1963), was the third official Antarctic expedition of the German Reich, by order of the "Commissioner for the Four Year Plan" Hermann Göring. Prussian State Councilor Helmuth Wohlthat was mandated with planning and preparation. The expedition's main objective was of economic nature, in particular the establishment of a whaling station and the acquisition of fishing grounds for a German whaling fleet in order to reduce the Reich's dependence on the import of industrial oils, fats and dietary fats. Preparations took place under strict secrecy as the enterprise was also tasked to make a feasibility assessment for a future occupation of Antarctica, Antarctic territory in the region between 20 ° West and 20 ° East. Background Like many other countries, German Empire, Germany sent expeditions to the Antarctic region in the late 19th and early 20th centuries, most of which were ...

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. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of 1,064,235 in 2022 ... 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 researche ...
