Austfonna glacier at Nordaustlandet, Svalbard, Norway

Austfonna is an ice cap located on Nordaustlandet in the Svalbard archipelago in Norway. Covering an area of 8,492 km2 it is the largest ice cap by area and with 1,900 km3 the second largest by volume in Europe, after the Vatnajökull in Iceland, and the seventh largest in the world.

Nordaustlandet island in the Svalbard archipelago

Nordaustlandet is the second-largest island in the archipelago of Svalbard, Norway, with an area of 14,443 square kilometres (5,576 sq mi). It lies north east of Spitsbergen, separated by Hinlopen Strait. Much of Nordaustlandet lies under large ice caps, mainly Austfonna and Vestfonna, the remaining parts of the north being tundra inhabited by reindeer and walruses. The island is uninhabited and lies entirely within Nordaust-Svalbard Nature Reserve.

Svalbard Archipelago in the Arctic Ocean

Svalbard is a Norwegian archipelago in the Arctic Ocean. Situated north of mainland Europe, it is about midway between continental Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and Edgeøya. Administratively, the archipelago is not part of any Norwegian county, but forms an unincorporated area administered by a governor appointed by the Norwegian government. Since 2002, Svalbard's main settlement, Longyearbyen, has had an elected local government, somewhat similar to mainland municipalities. Other settlements include the Russian mining community of Barentsburg, the research station of Ny-Ålesund, and the mining outpost of Sveagruva. Ny-Ålesund is the northernmost settlement in the world with a permanent civilian population. Other settlements are farther north, but are populated only by rotating groups of researchers.

Hinlopen Strait strait in Svalbard

Hinlopen Strait is the strait between Spitsbergen and Nordaustlandet in Svalbard, Norway. It is 150 kilometers (93 mi) long and 10 to 60 kilometers wide. The strait is difficult to pass because of pack ice. It is believed to have been named after Thijmen Jacobsz Hinlopen.

Vestfonna glacier at Nordaustlandet, Svalbard, Norway

Vestfonna is an ice cap located on the western part Nordaustlandet in the Svalbard archipelago in Norway. The glacier covers an area of about 2,500 km2. It is the third largest ice cap in Svalbard and Norway by area, after Austfonna and Olav V Land.

Nordaust-Svalbard Nature Reserve nature reserve

Nordaust-Svalbard Nature Reserve is located in the north-eastern part of the Svalbard archipelago in Norway. The nature reserve covers all of Nordaustlandet, Kong Karls Land, Kvitøya, Sjuøyane, Storøya, Lågøya, Wilhelm Island, Wahlbergøya and a small section of the north-east corner of Spitsbergen. The reserve is 55,354 square kilometres (21,372 sq mi), of which 18,663 square kilometres (7,206 sq mi) is on land and 36,691 square kilometres (14,166 sq mi) is on water—making it the largest preserved area in Norway. It includes the largest glacier in Norway, Austfonna, as well as Vestfonna and parts of Olav V Land. The reserve has been protected since 1 July 1973 and borders in the south to Søraust-Svalbard Nature Reserve.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
