Svalbard (Norwegian pronunciation: [ˈsʋɑlbɑɖ]) is an archipelago in the Arctic Ocean, constituting the northernmost part of Norway. Located north of mainland Europe, it is about midway between mainland Norway and the North Pole. The group of islands range from 74° to 81° north latitude, and from 10° to 35° east longitude. Spitsbergen is the largest island, followed by Nordaustlandet and Edgeøya. The administrative center is Longyearbyen, and other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund and the mining outpost of Sveagruva. The archipelago is administrated by the Governor of Svalbard.
The islands were first taken into use as a whaling base in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Spitsbergen Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian Arktikugol remain the only mining companies. Research and tourism have became important supplementary industries, featuring among others the University Centre in Svalbard and the Svalbard Global Seed Vault. No roads connect the settlements; instead snowmobiles, aircraft and boats serve inter-community transport. Svalbard Airport, Longyear serves as the main gateway.
