List of Antarctic and sub-Antarctic islands in the context of Antarctic realm

The Falkland Islands Dependencies was the constitutional arrangement from 1843 until 1985 for administering the various British territories in Sub-Antarctica and Antarctica which were governed from the Falkland Islands and its capital Stanley.

The South Orkney Islands are a group of islands in the Southern Ocean, about 604 km (375 mi) north-east of the tip of the Antarctic Peninsula and 844 km (524 mi) south-west of South Georgia Island. They have a total area of about 620 km (240 sq mi). The islands are claimed both by Britain (as part of the British Antarctic Territory since 1962, previously as a Falkland Islands Dependency) and by Argentina (as part of Argentine Antarctica). Under the 1959 Antarctic Treaty, sovereignty claims are held in abeyance.

Britain and Argentina both maintain bases on the islands. The Argentine base, Orcadas, established in 1904, is sited on Laurie Island. The 11 buildings of the Argentine station house up to 45 people during the summer, and an average of 14 during winter. The British Antarctic Survey base, Signy Research Station, is located on Signy Island and was established in 1947. Initially operated year-round, since 1995–1996 the Signy Research Station has been open only from November to April each year.
