Gough Island in the context of Tristan Archipelago

Bouvet Island (/ˈbuːveɪ/ BOO-vay; Norwegian: Bouvetøya [bʉˈvèːœʏɑ]) is an uninhabited subantarctic volcanic island and dependency of Norway. A protected nature reserve situated in the South Atlantic Ocean at the southern end of the Mid-Atlantic Ridge, it is the world's most remote island. Located north of the Antarctic Circle, Bouvet Island is not part of the southern region covered by the Antarctic Treaty System.

The island lies 1,700 km (1,100 mi; 920 nmi) north of the Princess Astrid Coast of Queen Maud Land, Antarctica, 1,870 km (1,160 mi; 1,010 nmi) east of the South Sandwich Islands, 1,845 km (1,146 mi; 996 nmi) south of Gough Island, and 2,520 km (1,570 mi; 1,360 nmi) south-southwest of the coast of South Africa. It has an area of 49 km (19 sq mi), 93 percent of which is covered by a glacier. The centre of the island is the ice-filled crater of an inactive volcano. Some skerries and one smaller island, Larsøya, lie along its coast. Nyrøysa, created by a rockslide in the late 1950s, is the only easy place to land and is the location of a weather station.

Saint Helena, Ascension and Tristan da Cunha is a British Overseas Territory located in the South Atlantic and consisting of the island of Saint Helena, Ascension Island, and the archipelago of Tristan da Cunha (including Gough Island). Its name was Saint Helena and Dependencies until 1 September 2009, when a new constitution came into force, giving the three islands equal status as three territories, with a grouping under the Crown.

Tristan da Cunha (/ˌtrɪstən də ˈkuːn(j)ə/), colloquially Tristan, is a remote group of volcanic islands in the South Atlantic Ocean. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, with its own constitution.

The territory consists of the inhabited island Tristan da Cunha, which has a diameter of roughly 11 kilometres (6.8 mi) and an area of 98 square kilometres (38 sq mi); the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. As of October 2018, the main island had 250 permanent inhabitants, who all hold British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel of a weather station on Gough Island.

The South African National Antarctic Programme (or SANAP) is the South African government's programme for research in the Antarctic and Subantarctic. Three research stations fall under this programme: the Antarctica research station SANAE IV, and one station each on the subantarctic islands Gough Island and Marion Island. These stations are managed and administered by the Directorate: Antarctic and Islands of the Department of Environmental Affairs. Borga Base was also operated by SANAP from 1969 to 1976.

The mission of the South African National Antarctic Programme is to increase understanding of the natural environment and life in the Antarctic and Southern Ocean through appropriate science and technology.
