It was decided to go beyond the budget boundaries, so the crews also bought two chronometers by inventor John Arnold (№ 518 and 2110), and two – by Paul Philipp Barraud (№ 920 and 922), three- and four-foot refractors with achromatic lenses, a 12-inch reflecting telescope, and for Simonov – a transit instrument and an attitude indicator.
Administratively, Argentine Antarctica is a department of the province of Tierra del Fuego, Antarctica, and South Atlantic Islands. This sector overlaps with Chilean and British claims but, under the Antarctic Treaty System , there are no attempts by Argentina or any other country to actually enforce territorial claims in Antarctica.
The Antarctic continental shelf is a submerged piece of the Antarctic continent that underlies a portion of the Southern Ocean — the ocean which surrounds Antarctica. The shelf is generally narrow and unusually deep, its edge lying at depths averaging 500 meters (the global mean is around 100 meters), with troughs extending as far as 2000 ...
The Chilean Antarctic Territory, or Chilean Antarctica (Spanish: Territorio Chileno Antártico, Antártica Chilena), is a part of West Antarctica and nearby islands claimed by Chile. It comprises the region south of 60°S latitude and between longitudes 53°W and 90°W , [ 2 ] partially overlapping the Antarctic claims of Argentina ( Argentine ...
West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet .
The Nimrod Expedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three expeditions to the Antarctic led by Ernest Shackleton and his second time to the Continent.
The East Antarctic Ice Sheet (EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic Mountains.
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
