Passage: Seven sovereign states had made eight territorial claims to land in Antarctica south of the 60° S parallel before 1961. These claims have been recognized only between the countries making claims in the area. All claim areas are sectors, with the exception of Peter I Island. None of these claims have an indigenous population. The South Orkney Islands fall within the territory claimed by Argentina and the United Kingdom, and the South Shetland Islands fall within the areas claimed by Argentina, Chile, and the United Kingdom. The UK, France, Australia, New Zealand and Norway all recognize each other's claims. None of these claims overlap. Prior to 1962, British Antarctic Territory was a dependency of the Falkland Islands and also included South Georgia and the South Sandwich Islands. The Antarctic areas became a separate overseas territory following the ratification of the Antarctic Treaty. South Georgia and the South Sandwich Islands remained a dependency of the Falkland Islands until 1985 when they too became a separate overseas territory.
