3H and 3He in the Beta Triangle: Observations of Gyre Ventilation and Oxygen Utilization Rates
Publisher: American Meteorological Society
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 ...
The Importance of Lateral Diffusion for the Ventilation of the Lower Thermocline in the Subtropical North Atlantic
Publisher: American Meteorological Society
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 ...
