Vostok Subglacial Highlands ( 80°0′S102°0′E / 80.000°S 102.000°E / -80.000; 102.000 Coordinates: 80°0′S102°0′E / 80.000°S 102.000°E / -80.000; 102.000 ) is a line of subglacial highlands trending NNW-SSE and forming an east extension of Gamburtsev Subglacial Mountains. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and named after Vostok , the flagship of the First Russian Antarctic Expedition, 1819-21 led by Fabian Gottlieb von Bellingshausen.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

National Science Foundation United States government agency

The National Science Foundation (NSF) is a United States government agency that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about US$7.8 billion, the NSF funds approximately 24% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing.

Lake Vostok

Lake Vostok is the largest of Antarctica's almost 400 known subglacial lakes. Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level. The surface of this fresh water lake is approximately 4,000 m (13,100 ft) under the surface of the ice, which places it at approximately 500 m (1,600 ft) below sea level.

Vostok Station Russian research station in Antarctica

Vostok Station is a Russian research station in inland Princess Elizabeth Land, Antarctica. Founded by the Soviet Union in 1957, the station lies at the southern Pole of Cold, with the lowest reliably measured natural temperature on Earth of −89.2 °C. Research includes ice core drilling and magnetometry. Vostok was named after Vostok, the lead ship of the First Russian Antarctic Expedition captained by Fabian von Bellingshausen.

Subglacial lake A lake under a glacier

A subglacial lake is a lake under a glacier, typically an ice cap or ice sheet. There are many such lakes, with Lake Vostok in Antarctica being by far the largest known on Earth at present.

90 Degrees East, also known as 90°E Lake, is a lake in Antarctica. With a surface area of about 2,000 square kilometres (770 sq mi), it is the second-largest known subglacial lake in Antarctica, after Lake Vostok. 90 Degrees East was discovered in January 2006, along with Sovetskaya. It is named after the 90th meridian east, on which it lies.

The Gamburtsev Mountain Range is a subglacial mountain range located in East Antarctica, just underneath the lofty Dome A, near the Southern Pole of Inaccessibility. The range was discovered by the 3rd Soviet Antarctic Expedition in 1958 and is named for Soviet geophysicist Grigoriy A. Gamburtsev. It is approximately 1,200 kilometres (750 mi) long, and the mountains are believed to be about 2,700 metres (8,900 ft) high, although they are completely covered by over 600 metres (2,000 ft) of ice and snow. The Gamburtsev Mountain Range is currently believed to be about the same size as the European Alps, and, as of 2008, it is unknown how the mountains were formed, though the current speculated age of the range is over 34 million years and possibly 500 million years. Current models suggest that the East Antarctic ice sheet was formed from the glaciers that began sliding down the Gamburtsev range at the end of the Eocene. Vostok Subglacial Highlands form an east extension of Gamburtsev Subglacial Mountains.

The Zélée Subglacial Trench is a subglacial valley on George V Coast, running north-northeast to south-southwest and coinciding with the trough cut by the Mertz Glacier. The feature was delineated by the Scott Polar Research Institute (SPRI)-NSF-TUD airborne radio echo sounding program, 1967–79, and named after the corvette Zélée of the French expedition of 1837–40 under Capt. Jules Dumont d'Urville.

Astrolabe Subglacial Basin is a subglacial basin to the south of the Adélie Coast and east of Porpoise Subglacial Highlands, trending north-south and containing the thickest ice — about 4,700 metres (15,400 ft) — measured in Antarctica. The basin was delineated by the SPRI-NSF-TUD airborne radio echo sounding program, 1967–79, and named after the Astrolabe, the flagship of the French Antarctic Expedition, 1837–40, under Captain Jules Dumont d'Urville.

Andrey Petrovich Kapitsa was a Russian geographer and Antarctic explorer, discoverer of Lake Vostok, the largest subglacial lake in Antarctica. He was a member of the Kapitsa family, a scientific dynasty in Russia.

There are hundreds of antarctic lakes, in Antarctica. In 2018 researchers at the Alfred Wegener Institute's Helmholtz Centre for Polar and Marine Research published a study they claimed cast doubt on earlier estimate that there were almost 400 subglacial antarctic lakes. Antarctica also has some relatively small regions that are clear of ice and snow, and there are some surface lakes in these regions. They called for on the ground seismic studies, or drilling, to determine a more reliable number.
