Geography

The Barents Sea is a marginal sea of the Arctic Ocean but is generally considered part of the Atlantic Ocean basin because it is connected to the Atlantic via the Norwegian Sea. It is recognized as a distinct Large Marine Ecosystem (LME 18) and a separate marine ecoregion in the MEOW classification. Its oceanography is characterized by a layered water-mass structure with warm, saline Atlantic water advecting eastward beneath colder, fresher Polar Surface Water and Arctic water masses. Authoritative sources including the joint Norwegian-Russian ecosystem survey reports and marine geography references confirm that the Barents Sea is part of the Atlantic Ocean basin. Therefore, the correct answer is Atlantic Ocean (A).
