Nils Gabriel Sefström
Nils Gabriel Sefström (2 June 1787 – 30 November 1845) was a Sweden, Swedish chemist. Sefström was a student of Jöns Jakob Berzelius, Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium. Vanadium was first discovered by the Spanish-Mexican mineralogist Andrés Manuel del Río in 1801. He named it erythronium. Friedrich Wöhler later confirmed that vanadium and erythronium were the same substance. Sefström was member of the Royal Swedish Academy of Sciences from 1815. The Spitzbergen glacier Sefströmbreen, and the mountain ridge of Sefströmkammen, are named after him.

Sefströmbreen
Sefströmbreen is a glacier in James I Land at Spitsbergen, Svalbard. It is debouching into Ekmanfjorden at the northern side of Isfjorden. The glacier is named after Nils Gabriel Sefström. During a surge in 1896 the glacier deposited large moraine ridges in the inner part of the fjord, and these can be seen at the islands of Coraholmen and Flintholmen. Sefströmbreen is included in the Nordre Isfjorden National Park. See also *Sefströmkammen Sefströmkammen is a mountain ridge in Nordenskiöld Land at Spitsbergen, Svalbard.

Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway.

Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. 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. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent commun ...

Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of 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 . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned.

The Norwegian Polar Institute (NPI; no, Norsk Polarinstitutt) is Norway's central governmental institution for scientific research, mapping and environmental monitoring in the Arctic and the Antarctic. The NPI is a directorate under Norway's Ministry of Climate and Environment. The institute advises Norwegian authorities on matters concerning polar environmental management and is the official environmental management body for Norwegian activities in Antarctica. Activities The institute's activities are focused on environmental research and management in the polar regions. The NPI's researchers investigate biodiversity, climate and environmental toxins in the Arctic and Antarctic, and in this context the institute equips and organizes large-scale expeditions to both polar regions. The institute contributes to national and international climate work, and is an active contact point for the international scientific community.
