Bouvetøya is located at 54° 25' S, 3° 21' E, the lenght is 7 km and breadht 9.5 km.The island is actually not a part of Antarctica which is defined as the area S of 60° S. Bouvetøya is the tip of a volcano that rises out of the Southern Ocean at the S end of the Mid-Atlantic Ridge. The island is 49 km² in size and almost totally covered by ice. Steep cliffs on all sides of the island make it extremely difficult to go ashore. Olavtoppen, the highest peak, is 780 metres above sea level. The island lies in extreme isolation, about 2200 km SE of Cape Aghulas, South Africa, in the SE part of the Atlantic Ocean
Opphav
After Jean Baptiste Lozier Bouvet, French explorer who discovered the island on January 1, 1739, in the ships "Aigle" and "Marie". Bouvet did not circle the island and heavy pack ice and fog prevented him from determining the nature of his discovery. Although evidence, recently uncovered, indicates that Bouvetøya was resighted in 1808 by the British ships Snow Swan and Otter, it was not until the visit of the German ship feature were determined and made known. By Royal Order in council January 23, 1928, Bouvetøya was placed under Norwegian sovereignty, and by an act of February 27, 1930, made a part of Norway. Bouvetøya has a maritime Antarctic climate, with an average temperature of -1°C. As a rule, it is cloaked in clouds or thick fog. In 1985, a Norwegian expedition had the good fortune to experience completely cloudless weather long enough to to be able to photograph the entire island for mapping purposes. The last volcanic eruption occured on Bouvetøya long ago, but volcanic gases have been registered since then. In 1978, a temperature of 25°C was recorded 30 cm below the surface of the ground. The vegetation consists mainly of mosses and lichens. The island's fauna consists mostly of seals, penguins and seabirds that breed colonially. Fur sealing was prohibited on Bouvetøya in 1929. In 1935, all seals in the area were declared protected species, and in 1971 Bouvetøya and the adjacent territorial waters were designated as a nature reserve, affording complete protection to the rich and distinctive plant and animal life. In 1979 three huts were set up by a research expedition. These are now lost, but in 1997 a new building was set up. A large container, equipped as a research station, can be used by scientists visiting the island
