Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. [1]
The Marie Byrd Land makes up a large portion of West Antarctica, consisting of the Area below the Antarctic Peninsula. The Marie Byrd land is a large formation of volcanic rock, characterized by 18 exposed and subglacial volcanoes. 16 of the 18 volcanoes are entirely covered by the antarctic ice sheet. [10]
Mass change of ice in Antarctica, 2002–2020. Contrasting temperature trends across parts of Antarctica mean that some locations, particularly at the coasts, lose mass while locations further inland continue to gain mass. These contrasting trends and the remoteness of the region make estimating an average trend difficult. [67]
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.
Antarctica is the southernmost land mass on Earth. The Geographical South Pole lies on the Polar Plateau at 90°00′S 00°00′W / 90.000°S -0.000°E / -90.000; - It is here that the southernmost human habitation on Earth is located: Amundsen–Scott South Pole Station (U.S. Administered Base).

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.
A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. [1] [2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. [3] [4] In the field of geology, a landmass is a defined section of continental crust extending above sea ...
