A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic Plate. The Antarctic (/ æ n ˈ t ɑːr t ɪ k / or / æ n ˈ t ɑːr k t ɪ k /, American English also / æ n t ˈ ɑːr t ɪ k / or / æ n t ˈ ɑːr k t ɪ k /; commonly / æ ˈ n ɑːr t ɪ k /) [Note 1] is a polar region around Earth's South Pole, opposite the Arctic region around ...
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 ...
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent , located in the Earth 's southern hemisphere , is centered asymmetrically around the South Pole and largely south of the Antarctic Circle .
A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique ('opposite to the Arctic') and, in turn, the Latin antarcticus ('opposite to the north').
When the air reaches the polar areas, it has cooled by radiation to space and is considerably denser than the underlying air. It descends, creating a cold, dry high-pressure area. At the polar surface level, the mass of air is driven away from the pole toward the 60th parallel, replacing the air that rose there, and the polar circulation cell ...
Antarctic Convergence. The Antarctic Convergence or Antarctic Polar Front is a marine belt encircling Antarctica, varying in latitude seasonally, where cold, northward-flowing Antarctic waters meet the relatively warmer waters of the sub-Antarctic.

These western ocean currents transport warm, tropical water polewards toward the polar regions. Ships crossing both oceans have taken advantage of the ocean currents for centuries. The Antarctic Circumpolar Current (ACC), or the West Wind Drift, is an ocean current that flows from west to east around Antarctica.
