  2. Antarctic ice sheet - Wikipedia

    en.wikipedia.org/wiki/Antarctic_ice_sheet

    The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi).

  3. East Antarctic Ice Sheet - Wikipedia

    en.wikipedia.org/wiki/East_Antarctic_Ice_Sheet

    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.

  4. Antarctica - Wikipedia

    en.wikipedia.org/wiki/Antarctica

    The cooling strengthens the polar vortex and so prevents the outflow of the cold air near the South Pole, which in turn cools the continental mass of the East Antarctic ice sheet. The peripheral areas of Antarctica, especially the Antarctic Peninsula, are then subjected to higher temperatures, which accelerate the melting of the ice. [105]

  5. West Antarctic Ice Sheet - Wikipedia

    en.wikipedia.org/wiki/West_Antarctic_Ice_Sheet

    The West Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere. It is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice ...

  6. 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.

  7. WAIS Divide - Wikipedia

    en.wikipedia.org/wiki/WAIS_Divide

    The WAIS Divide is the ice flow divide on the West Antarctic Ice Sheet (WAIS) which is a linear boundary that separates the region where the ice flows to the Ross Sea, from the region where the ice flows to the Weddell Sea. It is similar to a continental hydrographic divide.

  8. Geology of Antarctica - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Antarctica

    Antarctica was separated from South America at the Drake Passage by the Miocene, becoming isolated geologically and thermal isolation resulted in a colder climate while the continent was centered at the South Pole. Large ice sheets were present by the Middle-Late Eocene [11]: 43, 54–57, 226

  9. Ice stream - Wikipedia

    en.wikipedia.org/wiki/Ice_stream

    The Antarctic Ice Sheet is drained to the sea by several ice streams. The largest in East Antarctica is Lambert Glacier.In West Antarctica the large Pine Island and Thwaites Glaciers are currently the most out of balance, with a total net mass loss of 85 gigatonnes (84 billion long tons; 94 billion short tons) per year measured in 2006.
