Geosecs II,the 1970 North Atlantic station: Hydrographic features,oxygen, and nutrients

Profiles of salinity, temperature, oxygen and nutrients for a station at 35°46.5′N and 67°59.8′W show the influence of the five major sources of deep water in the North Atlantic Ocean. The presence of distinct, identifiable cores of water types, far removed from their sources, together with linear relationships between salinity and both oxygen and silicate in the deep water suggest that horizontal mixing processes predominate over vertical dissipation and in situ production or loss processes in determining the distribution of these tracers in the deep western Atlantic Ocean.
