Water Mass Properties Derived From Satellite Observations in the Barents Sea
International audience The Barents Sea is a region of deep water formation where Atlantic Water is converted into cooler, fresher Barents Sea Water. Barents Sea Water properties exhibit variability at seasonal, interannual, and decadal timescales. This variability is transferred to Arctic Intermedia...
