Abstract: Isopycnal maps of 3H?3He age (τ) with about 100 km resolution have been obtained for a 1000-km scale area in the eastern subtropical North Atlantic. The midscale texture of the maps is consistent with isopycnal diffusivities ...

Abstract: An analysis of the physical mechanisms contributing to the ventilation of the lower subtropical thermocline (26.5 < σ? < 27.3) of the North Atlantic is presented. Examination of the surface forcing suggests that this density ...
