Iceland–Scotland Overflow Water

E728851

deep water mass overflow water water mass

Iceland–Scotland Overflow Water is a cold, dense deep-water mass that flows southward from the Nordic Seas across the Iceland–Scotland Ridge, contributing to the formation of North Atlantic Deep Water and the global thermohaline circulation.
