Open sea, Northern Hemisphere.
It is bordered by Greenland, Iceland, Spitsbergen, and Norway. A submarine ridge linking Greenland, Iceland, the Faroe Islands, and northern Scotland separates the Norwegian Sea from the Atlantic Ocean. The sea is crossed by the Arctic Circle, but the warm Norway Current that flows northeast off the Norway coast produces generally ice-free conditions. Colder currents mixing with this warm water create excellent fishing grounds.
