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.
Signy Island is a small subantarctic island in the South Orkney Islands of Antarctica. It was named by the Norwegian whaler Petter Sørlle (1884–1933) after his wife, Signy Therese.
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. The Bellingshausen Station was named after this captain..
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second largest uninhabited island in the world, after Devon Island.
Thule Island, also called Morrell Island, is one of the southernmost of the South Sandwich Islands, part of the grouping known as Southern Thule. It is named, on account of its remote location, after the mythical land of Thule, said by ancient geographers to lie at the extreme end of the Earth. The alternative name Morrell Island is after Benjamin Morrell, an American explorer and whaling captain. It was espied by James Cook and his Resolution crew on 31 January 1775 during his attempt to find Terra Australis.
Canada Glacier is a small glacier flowing south-east into the northern side of Taylor Valley in Victoria Land, Antarctica. It is in the Ross Dependency. Its melting season is in the summer.
This is a list of extreme points in Antarctica.
Molodyozhnaya was a Soviet, then Russian research station in East Antarctica at 67°40′S 45°50′E. After being mothballed in 1990, it was reopened in 2006 to operate on a seasonal basis. In Russian, the station is sometimes referred to as the capital of Antarctica.
Penguin Island is one of the smaller of the South Shetland Islands of Antarctica.
The Vestfold Hills are rounded, rocky, coastal hills, 411 square kilometres (159 sq mi) in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between 30 and 90 metres in height, with the highest summit reaching nearly 160 metres (520 ft).
Lake Untersee is the largest surface freshwater lake in the interior of the Gruber Mountains of central Queen Maud Land in East Antarctica. It is situated 90 kilometres (56 mi) to the southwest of the Schirmacher Oasis. The lake is approximately 6.5 kilometres (4.0 mi) long and 2.5 kilometres (1.6 mi) wide, with a surface area of 11.4 square kilometres (4.4 sq mi), and a maximum depth of 169 metres (554 ft). The lake is permanently covered with ice and is partly bounded by glacier ice.
The Schirmacher Oasis is a 25 km long and up to 3 km wide ice-free plateau with more than 100 freshwater lakes. It is situated in the Schirmacher Hills on the Princess Astrid Coast in Queen Maud Land in East Antarctica, and is on average 100 metres above sea level. With an area of 34 km², the Schirmacher Oasis ranks among the smallest Antarctic oases and is a typical polar desert.
Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres, it is the fifth-largest continent and nearly twice the size of Australia. At 0.00008 people per square kilometre, it is by far the least densely populated continent. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Byers Peninsula is a mainly ice-free peninsula forming the west end of Livingston Island in the South Shetland Islands of Antarctica. It occupies 60 km2 (23 sq mi), borders Ivanov Beach to the northeast and is separated from Rotch Dome on the east by the ridge of Urvich Wall. The peninsula features more than 60 meltwater streams and as many lakes, notably Midge Lake, Limnopolar Lake and Basalt Lake. Byers Peninsula has a regime of special environmental protection under the Antarctic Treaty System and requires a permit to enter.
Dee Island is the ice-free island lying between Greenwich Island and Aitcho Islands in the South Shetland Islands, Antarctica and is separated from Greenwich Island to the south by the 850 m (930 yd) wide Orión Passage and from Aitcho Islands to the northeast by the 1.1 km (0.68 mi) wide Villalón Passage. Extending 1.9 by 1.37 km, with the conspicuous Burro Peaks in the southeast rising to 190 m (620 ft), and surface area 197 hectares. The small Montufar Island and Araguez Island are lying 650 m (710 yd) east of Dee Island and 200 m (220 yd) east of its southern tip Dragash Point respectively. The area was visited by 19th century sealers.
Lake Burton, also known as Burton Lagoon, is a meromictic and saline lake in the Vestfold Hills of Princess Elizabeth Land in Eastern Antarctica. Princess Elizabeth Land, including the lake, is claimed by Australia as part of the Australian Antarctic Territory. The lake has a surface area of 1.35 km2 (0.52 sq mi), a volume of 9.69 million m3, a maximum depth of 18.3 metres (60 ft) and a mean depth of 7.16 metres (23.5 ft). The lake is named after H. R. Burton, a biologist working in the Vestfold Hills of Antarctica.
Vostok was a 28-gun sloop-of-war of the Imperial Russian Navy, the lead ship of the First Russian Antarctic Expedition in 1819–1821, during which Fabian Gottlieb von Bellingshausen and Mikhail Lazarev circumnavigated the globe, discovered the continent of Antarctica and twice circumnavigated it, and discovered a number of islands and archipelagos in the Southern Ocean and the Pacific.
Juturna Lake is the roughly triangular lake extending 220 m in west-east direction and 150 m in north-south direction at the east extremity of South Beaches on Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. Its surface area is 1.9 ha. The lake is separated from sea by a 40 to 57 m wide strip of land, and drains by way of a 260 m long stream flowing into the sea west of Rish Point. It is surmounted by Ritli Hill on the east. The area was visited by early 19th century sealers.
Blue Lake is the largest of several small frozen lakes near Cape Royds, Ross Island, lying 0.5 nautical miles north-northeast of Flagstaff Point. Named by the Nimrod Expedition (1907-09) on account of the intensely vivid blue color of its ice.
