A continent lying chiefly within the Antarctic Circle and asymmetrically centered on the South Pole. Some 95 percent of Antarctica is covered by an icecap averaging 1.6 km (1 mi) in thickness. The region was first explored in the early 1800s, and although there are no permanent settlements, many countries have made territorial claims. The Antarctic Treaty of 1959, signed by 12 nations, prohibited military operations on the continent and provided for the interchange of scientific data.
