Bouvet Island (Bouvetøya ) is an uninhabited subantarctic high island and dependency of Norway located in the South Atlantic Ocean at, 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 1700 km north of the Princess Astrid Coast of Queen Maud Land, Antarctica and 2600 km south-southwest of the coast of South Africa.
The island has an area of 49 km2, 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, Larsøya, lie along the coast. Nyrøysa, 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 was named Bouvet Island, or "Bouvetøya" in Norwegian. After a dispute with the United Kingdom, it was declared a Norwegian dependency in 1930. It became a nature reserve in 1971.
