The Norwegian Sea (Norwegian: Norskehavet) is a marginal sea in the North Atlantic Ocean, northwest of Norway. It is located between theNorth Sea (i.e. north of the United Kingdom) and the Greenland Sea and adjoins the North Atlantic Ocean to the west and the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the North, the Jan Mayen Ridge separates it from the Greenland Sea.
