The Antarctic continental shelf is a submerged piece of the Antarctic continent that underlies a portion of the Southern Ocean — the ocean which surrounds Antarctica. The shelf is generally narrow and unusually deep, its edge lying at depths averaging 500 meters (the global mean is around 100 meters), with troughs extending as far as 2000 ...
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,-k t ɪ k /, US also / æ n t ˈ ɑːr t ɪ k,-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 North Pole.
Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km 2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
It has an area of more than 14.2 million km 2. Antarctica is the largest ice desert in the world. Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet , the world's largest ice sheet and also its largest reservoir of fresh water .
The Antarctic Peninsula, roughly 1,000 kilometres (650 mi) south of South America, is the northernmost portion of the continent of Antarctica.Like the associated Andes, the Antarctic Peninsula is an excellent example of ocean-continent collision resulting in subduction. [1]
The highest-emission scenario results in a median rise of 1.46 m (5 ft) with a minimum of 60 cm (2 ft) and a maximum of 2.89 m (9 + 1 ⁄ 2 ft). [ 70 ] 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 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.
