Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north- and south poles. The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole ...
Fram was used by Roald Amundsen in his southern polar expedition from 1910 to 1912, the first to reach the South Pole, during which Fram reached 78° 41' S. Preservation of Fram The ship was left to decay in storage from 1912 until the late 1920s, when Lars Christensen , Otto Sverdrup and Oscar Wisting initiated efforts to preserve it via the ...
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and ...
The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
Fram leaves Bergen on 2 July 1893, bound for the Arctic Ocean Period map showing the regions traversed by the expedition [1]. Nansen's Fram expedition of 1893–1896 was an attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural east–west current of the Arctic Ocean.
Scott and his financial backers saw the expedition as having a scientific basis, while also wishing to reach the pole. However, it was recognised by all involved that the South Pole was the primary objective ("The Southern Journey involves the most important object of the Expedition" – Scott), and had priority in terms of resources, such as the best ponies and all the dogs and motor sledges ...
Polar exploration is the process of exploration of the polar regions of Earth – the Arctic region and Antarctica – particularly with the goal of reaching the North Pole and South Pole, respectively. Historically, this was accomplished by explorers making often arduous travels on foot or by sled in these regions, known as a polar expedition.
Left to right: Roald Amundsen, Helmer Hanssen, Sverre Hassel and Oscar Wisting after first reaching the South Pole on 16 December 1911. The Heroic Age of Antarctic Exploration was an era in the exploration of the continent of Antarctica which began at the end of the 19th century, and ended after the First World War; the Shackleton–Rowett Expedition of 1921–1922 is often cited by historians ...
