Humboldt Mountains (Antarctica)
The Humboldt Mountains are a group of mountains immediately west of the Petermann Ranges, forming the westernmost portion of the Wohlthat Mountains in Queen Maud Land, Antarctica. History 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 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 Site or Monument (HSM 78), following a proposal by India to the Antarctic Treaty Consultative Meeting.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

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 ...

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 ...

Commemorative Plaque
A commemorative plaque, or simply plaque, or in other places referred to as a historical marker, historic marker, or historic plaque, is a plate of metal, ceramic, stone, wood, or other material, typically attached to a wall, stone, or other vertical surface, and bearing text or an image in relief, or both, to commemorate one or more persons, an event, a former use of the place, or some other thing. Many modern plaques and markers are used to associate the location where the plaque or marker is installed with the person, event, or item commemorated as a place worthy of visit. A monumental plaque or tablet commemorating a deceased person or persons, can be a simple form of church monument. Most modern plaques affixed in this way are commemorative of something, but this is not always the case, and there are purely religious plaques, or those signifying ownership or affiliation of some sort. A plaquette is a small plaque, but in English, unlike many European languages, the term is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...
