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 ...
The outbreak of the First World War in 1914 delayed the start of Amundsen's northern polar drift—to which the South Pole expedition had been intended as a preliminary—until July 1918. He then set off in a specially constructed vessel, Maud, which remained in Arctic waters for the next seven years.
Karen Kylleso accomplished the feat overnight between Monday and Tuesday, 114 years after fellow Norwegian and polar explorer Roald Amundsen became the first person to reach the South Pole.
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 ...
The south magnetic pole, also known as the magnetic south pole, is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed perpendicular to the nominal surface. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's ...
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]
The polar vortex is a large area of cold air and low pressure that normally spins over the North and South Poles. During the winter months and when the jet stream allows, this cold air can drop ...
