Bouvet Island is an island in the far southern Atlantic Ocean. This sub-antarctic volcanic island is located roughly in the triangle between South Africa, the southern tip of South America and Antarctica. Officially being a dependent area of Norway, it is generally believed to be the most isolated uninhabited island anywhere in the world. In fact, the nearest piece of land (except a small island roughly 100 kilometres away, which technically is part of Bouvet as well) is Queen Maud Land on Antarctica, about 1,700 kilometres away to the south.
Bouvet Island is a volcanic island constituting the top of a volcano located as the southern end of the Mid-Atlantic Ridge in the South Atlantic Ocean. The islands measures 9.5 by 7 kilometres and covers an area of 49 square kilometres including a number of small rocks and skerries and one sizable island, Larsøya. It is located in the Subantarctic, south of the Antarctic Convergence, which, by some definitions, would place the island in the Southern Ocean. Bouvet Island is the most remote island in the world. The closest land is Queen Maud Land of Antarctica, which is 1,700 kilometres and Gough Island, 1,600 kilometres to the north. The closest inhabited location is Cape Agulhas, South Africa, 2,200 kilometres to the northeast.
Nyrøysa is a 2 by 0.5 kilometres terrace located on the northwest coast of the island. Created by a rock slide sometime between 1955 and 1957, it is the island's easiest access point. It is the site of the weather station. The northwest corner is the peninsula of Kapp Circoncision. From there, east to Kapp Valdivia, the coast is known as Morgenstiernekysten. Store Kari is an islet located 1.2 kilometres east of the cape. From Kapp Valdivia, southeast to Kapp Lollo, on the east side of the island, the coast is known as Victoria Terrasse. From there to Kapp Fie at the southeastern corner, the coast is known as Mowinckelkysten. Svartstranda is a section of black sand which runs 1.8 kilometres along the section from Kapp Meteor, south to Kapp Fie. After rounding Kapp Fie, the coast along the south side is known as Vogtkysten. The westernmost part of it is the 300 metres long shore of Sjøelefantstranda. Off Catoodden, on the south-western corner, lies Larsøya, the only island of any size off Bouvetøya. The western coast from Catoodden north to Nyrøysa, is known as Esmarchkysten. Midway up the coast lies Norvegiaodden (Kapp Norvegia) and 0.5 kilometres off it the skerries of Bennskjæra.
93 percent of the island is covered by glaciers, giving it a domed shape. The summit region of the island is Wilhelmplatået, slightly to the west of the island's center. The plateau is 3.5 kilometres across and surrounded by several peaks. The tallest is Olavtoppen, 780 metres above sea level, followed by Lykketoppen (766 metres above sea level) and Mosbytoppane (670 metres above se level. Below Wilhelmplatået is the main caldera responsible for creating the island. The last eruption took place 2,000 BC, producing a lava flow at Kapp Meteor. The volcano is presumed to be in a declining state. The temperature 30 centimetres below the surface is 25 °C.
The island's total coastline is 29.6 kilometres. Landing on the island is very difficult, as it normally experiences high seas and features a steep coast.During the winter, it is surrounded by pack ice. The Bouvet Triple Junction is located 275 kilometres west of Bouvet Island. It is a triple junction between the South American Plate, the African Plate and the Antarctic Plate, and of the Mid-Atlantic Ridge, the Southwest Indian Ridge and the American–Antarctic Ridge.
The island is located south of the Antarctic Convergence, giving it a marine Antarctic climate dominated by heavy clouds and fog. It experiences a mean temperature of -1 °C, with January average of 1 °C and September average of -3 °C. The monthly high mean temperatures fluctuate little through the year. The peak temperature of 14 °C was recorded in March 1980, caused by intense sun radiation. Spot temperatures as high as 20 °C have been recorded in sunny weather on rock faces. The island predominantly experiences a weak west wind.
The island is very hard to get to in the first place. And second of all, as there are no harbours whatsoever, you need to anchor offshore. Although the island has an automated weather station, only a few dozen of people are believed to have ever set foot on land.
