Antarctica, Antarctic Peninsula

The Antarctic Peninsula is the northernmost part of mainland Antarctica, extending 1300 km from Cape Adams to a point south of the Eckland Islands. It is a prominent peninsula with a string of bedrock islands beneath its ice sheet, separated by deep channels. Located 1000 km from Tierra del Fuego across the Drake Passage, the peninsula hosts numerous research stations. It is subject to disputed sovereignty claims by Argentina, Chile, and the UK, none of which are internationally recognized under the Antarctic Treaty System. Argentina has the most personnel stationed there.
