Bjørnøya
Bjørnøya  (Bear island) is an island in the Barents sea  450 km north of Tromsø, roughly halfway to Svalbard. Geomagnetic observation was introduced at the island by a Polish expedition during the Second Polar Year 1932/33. Norwegians continued the recordings until the station was destroyed by actions of war in 1941. New instruments were installed in 1949. Transition to digital recording took place in 1986. The magnetometer is operated with the assistance of the Meteorological Institute of Norway and located at the meteorological station at Bear island.
