  2. Antarctic ice sheet - Wikipedia

    en.wikipedia.org/wiki/Antarctic_ice_sheet

    Over longer timescales, the West Antarctic ice sheet, which is much smaller than the East Antarctic ice sheet and is grounded deep below sea level, is considered highly vulnerable. The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [98]

  3. West Antarctic Ice Sheet - Wikipedia

    en.wikipedia.org/wiki/West_Antarctic_Ice_Sheet

    A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.

    West Antarctica on the left. Typical landscape for the Antarctic Peninsula area, with fjords, high coastal mountains and islands. Click on the image for geographical details. West Antarctica is the smaller part of the continent, (50° – 180°W), divided into:

  5. East Antarctic Ice Sheet - Wikipedia

    en.wikipedia.org/wiki/East_Antarctic_Ice_Sheet

    Location and diagram of Lake Vostok, a prominent subglacial lake beneath the East Antarctic Ice Sheet. East Antarctic Ice Sheet is located directly above the East Antarctic Shield – a craton (stable area of the Earth's crust) with the area of 10,200,000 km 2 (3,900,000 sq mi), which accounts for around 73% of the entire Antarctic landmass. [19]

  6. Geology of Antarctica - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Antarctica

    The frozen continent of Antarctica was the last continent humanity set foot on. The first documented landings made below the Antarctic Circle took place in 1820, when Admiral Fabian Gottlieb von Bellingshausen and the crew of the Vostok and Mirny, as part of the Russian Antarctic Expedition, made land at Peter I Island and Alexander Island.

  7. Ice sheet - Wikipedia

    en.wikipedia.org/wiki/Ice_sheet

    Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.

  8. List of Antarctic ice shelves - Wikipedia

    en.wikipedia.org/wiki/List_of_Antarctic_ice_shelves

    Ice shelves are attached to a large portion of the Antarctic coastline. Their total area is 1,541,700 km 2 . [ 1 ] Names are also listed in the Scientific Committee on Antarctic Research , Gazetteer. [ 2 ]

  9. WAIS Divide - Wikipedia

    en.wikipedia.org/wiki/WAIS_Divide

    A site with high annual ice accumulation and thick ice was needed to provide a high time resolution record extending ~80,000 years into the past. This required drilling in West Antarctica which has higher ice accumulation rates than East Antarctica.
