Area: Approximately 5,500,000 square miles; an area twice this size is covered by ice in winter
Location: Antarctica is the southernmost country in the world. It is completely surrounded by water.
Geography: Antarctica is a land of rugged superlatives: the coldest, windiest, driest, and highest (on average) of the world’s large land masses. Its highest point is the Vinson Massif, a mountain16,864 feet high. Antarctica’s lowest point is at the Bentley Subglacial Trench, 8,200 feet below sea level, where the overlying ice is nearly 10,000 feet thick. The Antarctic icecap holds the majority of all fresh water on earth.
Population (estimate, south of 60°S): Approximately 1,000 year-round residents (scientists and supporting staff); about 4,000 residents during the Antarctic summer
Time zone: Bases in Antarctica typically observe the time zone of their home country or supply line.
