Hansen Spur
Hansen Spur () is a spur, long, descending from the northwest side of Nilsen Plateau, in the Queen Maud Mountains of Antarctica, and terminating at the edge of Amundsen Glacier just east of the Olsen Crags. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Ludvig Hansen, a member of the sea party aboard the ''Fram'' on Amundsen's Norwegian expedition of 1910–12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount L. Hansen," a name applied for an unidentified mountain in the general area. The Blackwall Glacier flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier Amundsen Glacier () is a major Antarctic glacier, about 7 to 11 km (4 to 6 nmi) wide and 150 km (80 nmi) long, originating on the polar plateau where it drains the area to the south and west of Nilsen Plateau, and descendin .... ...

Nilsen Plateau
Nilsen Plateau () is a rugged, ice-covered plateau in Antarctica. When including Fram Mesa, the plateau is about 30 nautical miles (60 km) long and 1 to 12 nautical miles (22 km) wide, rising to 3,940 m between the upper reaches of the Amundsen and Scott Glaciers, in the Queen Maud Mountains. Discovered in November 1911 by the Norwegian expedition under Roald Amundsen, and named by him for Captain Thorvald Nilsen, commander of the ship ''Fram Fram may refer to: Ships * ''Fram'' (ship), an arctic exploration vessel from Norway * MS ''Fram'', expedition cruise ship owned by Hurtigruten Group Places and geography * Fram, Paraguay, a town in Itapúa, Paraguay * Fram Formation, a se ...''.

Queen Maud Mountains
The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Despite the name, they are not located within Queen Maud Land. Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.

Amundsen Glacier
Amundsen Glacier () is a major Antarctic glacier, about 7 to 11 km (4 to 6 nmi) wide and 150 km (80 nmi) long, originating on the polar plateau where it drains the area to the south and west of Nilsen Plateau, and descending through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks. The tributary Blackwall Glacier flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier. It was discovered by Rear Admiral Byrd on the South Pole flight in November 1929. The name was proposed for Roald Amundsen by Laurence Gould, leader of the Byrd AE geological party which sledged past the mouth of the glacier in December 1929.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fram (ship)
''Fram'' ("Forward") is a ship that was used in expeditions of the Arctic and Antarctic regions by the Norwegian explorers Fridtjof Nansen, Otto Sverdrup, Oscar Wisting, and Roald Amundsen between 1893 and 1912. It was designed and built by the Scottish-Norwegian shipwright Colin Archer for Fridtjof Nansen's 1893 Arctic expedition in which the plan was to freeze ''Fram'' into the Arctic ice sheet and float with it over the North Pole. ''Fram'' is preserved as a museum ship at the Fram Museum in Oslo, Norway. Construction Nansen's ambition was to explore the Arctic farther north than anyone else. To do that, he would have to deal with a problem that many sailing on the polar ocean had encountered before him: the freezing ice could crush a ship. Nansen's idea was to build a ship that could survive the pressure, not by pure strength, but because it would be of a shape designed to let the ice push the ship up, so it would "float" on top of the ice. ''Fram'' is a three-masted sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amundsen
Roald Engelbregt Gravning Amundsen (, ; ; 16 July 1872 – ) was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration. Born in Borge, Østfold, Norway, Amundsen began his career as a polar explorer as first mate on Adrien de Gerlache's Belgian Antarctic Expedition of 1897–1899. From 1903 to 1906, he led the first expedition to successfully traverse the Northwest Passage on the sloop ''Gjøa''. In 1909, Amundsen began planning for a South Pole expedition. He left Norway in June 1910 on the ship ''Fram'' and reached Antarctica in January 1911. His party established a camp at the Bay of Whales and a series of supply depots on the Barrier (now known as the Ross Ice Shelf) before setting out for the pole in October. The party of five, led by Amundsen, became the first to successfully reach the South Pole on 14 December 1911. Following a failed attempt in 1918 to reach the North Pole by traversing the Nor ...

Amundsen's South Pole Expedition
The first ever expedition to reach the South Pole, geographic Southern Pole was led by the Norwegian explorer Roald Amundsen. He and four others arrived at the pole on 14 December 1911, five weeks ahead of a British party led by Robert Falcon Scott as part of the Terra Nova Expedition. Amundsen and his team returned safely to their base, and later heard that Scott and his four companions had died on their return journey. Amundsen's initial plans had focused on the Arctic and the conquest of the North Pole by means of an extended drift in an icebound ship. He obtained the use of Fridtjof Nansen's polar exploration ship ''Fram (ship), Fram'', and undertook extensive fundraising. Preparations for this expedition were disrupted when, in 1909, the rival American explorers Frederick Cook and Robert Peary each claimed to have reached the North Pole. Amundsen then changed his plan and began to prepare for a conquest of the South Pole; uncertain of the extent to which the public and hi ...

Ridges Of The Ross Dependency
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic Dendrite derives from the Greek word "dendron" meaning ( "tree-like"), and may refer to: Biology *Dendrite, a branched projection of a neuron *Dendrite (non-neuronal), branching projections of certain skin cells and immune cells Physical * Dendr ... ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
