Bouvet Island is an uninhabited subantarctic high island and dependency of Norway located in the South Atlantic Ocean thus locating it north of and outside the Antarctic Treaty System. It lies at the southern end of the Mid-Atlantic Ridge and is the most remote island in the world, approximately 1,700 kilometres (1,100 mi) north of the Princess Astrid Coast of Queen Maud Land, Antarctica, 1,900 kilometres (1,200 mi) east of the South Sandwich Islands, 1,600 kilometres (990 mi) south of Gough Island, and 2,600 kilometres (1,600 mi) south-southwest of the coast of South Africa.
The island has an area of 49 square kilometres (19 sq mi), of which 93 percent is covered by a glacier. The centre of the island is an ice-filled crater of an inactive volcano. Some skerries and one smaller island, Larsoya, lie along the coast. Nyroysa, created by a rock slide in the late 1950s, is the only easy place to land and is the location of a weather station.
The island was first spotted on 1 January 1739 by Frenchman Jean-Baptiste Charles Bouvet de Lozier, on a French exploration mission in the South Atlantic with the ships Aigle and Marie. They did not make a landfall, and he mislabeled the coordinates for the island and the island was not sighted again until 1808, when the British whaler captain James Lindsay named it Lindsay Island. The first claim of landing, although disputed, was by American sailor Benjamin Morrell. In 1825, the island was claimed for the British Crown by George Norris, who named it Liverpool Island. He also reported Thompson Island as nearby, although this was later shown to be a phantom island. The first Norvegia expedition landed on the island in 1927 and claimed it for Norway. At this time, the island became named Bouvet Island, or "Bouvetoya" in Norwegian. After a dispute with the United Kingdom, it was declared a Norwegian dependency in 1930. It became a nature reserve in 1971.
