The Southern Ocean is a proposed ocean surrounding Antarctica, dominated by the Antarctic Circumpolar Current, generally the ocean south of 60 degrees south latitude. The Southern Ocean is partially covered in sea ice, the extent of which varies according to the season. The Southern Ocean is the second smallest of the five named oceans.
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
Antarctica is colder than the Arctic region, as much of Antarctica is over 3,000 m (9,800 ft) above sea level, where air temperatures are colder. The relative warmth of the Arctic Ocean is transferred through the Arctic sea ice and moderates temperatures in the Arctic region.
The striking images, made from sonar readings, can help boats avoid dangerous obstacles in the poorly understood Southern Ocean. Hi-res images show the ocean floor around Antarctica in ...
The Amundsen Sea area of Antarctica Antarctic iceberg floating in the Amundsen Sea water, October 2009. The Amundsen Sea is an arm of the Southern Ocean off Marie Byrd Land in western Antarctica. It lies between Cape Flying Fish (the northwestern tip of Thurston Island) to the east and Cape Dart on Siple Island to the west.
As of today, there have been 138 possible volcanoes identified in West Antarctica. [3] There is limited knowledge about West Antarctic Volcanoes due to the presence of the West Antarctic Ice Sheet, which heavily covers the West Antarctic Rift System —a likely hub for volcanic activity. [ 4 ]
A23a formed in 1986 when it calved from the Filchner-Ronne Ice Shelf on the northwestern side of Antarctica. Unlike other icebergs that float off, A23a became stuck as it hit the seafloor of the ...
