Antarctic Peninsula (Antarctica)

The Antarctic Peninsula is Antarctica mainland's northernmost part, located at the base of Southern Hemisphere. It is the largest, most prominent peninsula in Antarctica, extending 800 ml (1300 km) from a line between Cape Adams in Weddell Sea and a point on mainland located south of Eklund Islands. Under the ice sheet covering it, the Antarctic Peninsula consists of bedrock islands, separated by deep channels. The bottoms of these channels lie at depths substantially below current sea level and are joined by grounded ice sheet. South America's southernmost tip, Tierra del Fuego, lies just about 620 ml (1000 km) away across Drake Passage.

The Antarctic Peninsula is dotted with research stations. This territory is part of disputed claims by the UK, Argentina and Chile. None of the claims, however, has international recognition. Under the Antarctic Treaty System, respective countries don't attempt to enforce their claims. Argentina has the most personnel and bases stationed on the Antarctic Peninsula. Tourism to this destination started in the 1950s and most ship-based tourists depart from Ushuaia, Argentina.
