British Antarctic Territory — De Facto Map

British Antarctic Territory — British Antarctic Territory · Frozen by the Antarctic Treaty · the United Kingdom.

Interactive de facto map of British Antarctic Territory, a territory of the United Kingdom. The oldest claim, made by letters patent in 1908 as part of the Falkland Islands Dependencies and a British overseas territory of its own since 1962, between 20°W and 80°W. It takes in the whole Peninsula, which Argentina and Chile claim too. The British Antarctic Survey runs Rothera and Halley here. Frozen, like every claim, by the Antarctic Treaty of 1959. Explore British Antarctic Territory on the map alongside the other overseas holdings of the United Kingdom, drawn as they are administered on the ground.
