East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying on the Indian Ocean side of the Transantarctic Mountains. It is the coldest, highest, windiest, driest and most isolated land mass on Earth and includes a number of lofty mountains.
==Location and description==
Almost completely covered in thick, permanent ice, East Antarctica comprises Coats Land, Queen Maud Land, Enderby Land, Kemp Land, Mac. Robertson Land, Princess Elizabeth Land, Wilhelm II Land, Queen Mary Land, Wilkes Land, Adélie Land, George V Land, Oates Land and Victoria Land. All but a small portion of this region lies within the Eastern Hemisphere, a fact that has suggested the name. The name has been in existence for more than 90 years (Balch, 1902; Nordenskjöld, 1904), but its greatest use followed the International Geophysical Year (1957–58) and explorations disclosing that the Transantarctic Mountains provide a useful regional separation of East Antarctica and West Antarctica. The name was approved in the United States by the Advisory Committee on Antarctic Names (US-ACAN) in 1962. East Antarctica is generally higher than West Antarctica, and is considered the coldest place on Earth.
The subglacial Gamburtsev Mountain Range, about the size of the European Alps, in the center of East Antarctica, are believed to have been the nucleation site for the East Antarctic Ice Sheet.
