United Kingdom American Dependencies - British antarctic territory
Created on 3 March 1962 from former Falkland Islands dependencies, the British Antarctic Territory (BAT) lies south of 60° S and between 20° and 80° W , and consists of the South Shetlands, 4,662 sq km (1,800 sq mi); the South Orkneys, 622 sq km (240 sq mi); and Graham Land on the Antarctic continent. The territory is governed by a UK-appointed high commissioner, who also serves as governor of the Falklands. Three British Antarctic Survey stations are inhabited year-round: Signy on the South Orkneys, Rothera on Adelaide Island, and Halley V on moving ice along the Caird coast. Their personnel varies from 50 in the winter to 150 during the summer. The bases of 12 other Antarctic Treaty nations lie within the BAT claim on the Antarctic continent, with an estimated population of 1,000 in winter to 2,500 in the summer.
