    en.wikipedia.org/wiki/Southern_Ocean_overturning...

    A schematic overview of the Southern Ocean overturning circulation. The arrows point in the direction of the water movement. The lower cell of the circulation is depicted by the upwelling arrows south of the Antarctic Circumpolar Current (ACC) and the formation of Antarctic Bottom Water beneath the sea ice of Antarctica due to buoyancy loss.

  3. Antarctic Circumpolar Current - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Circumpolar_Current

    The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. Associated with the Circumpolar Current is the Antarctic Convergence , where the cold Antarctic waters meet the warmer waters of the subantarctic ...

    en.wikipedia.org/wiki/Climate_of_Antarctica

    Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt—around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice—the seas would rise by over 60 m (200 ft). [22]

    Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet..

    As with other neighboring parts of Antarctica, the Weddell Sea shares a common geological history with southernmost South America. In southern Patagonia at the onset of the Andean orogeny in the Jurassic extensional tectonics created the Rocas Verdes Basin , a back-arc basin whose surviving southeastward extension forms the Weddell Sea.
