Figure 10. Eddy diffusion and CDW intrusion. Top: same as the lower panel of Fig. 9 (thickness-based diffusivity for CDW), magnified for three continental margins (Prydz Bay, Princess Elizabeth Trough, and off Wilkes Land). Middle: isopycnal CDW temperature (same as Fig. 3, right-middle panel). Vectors annotate where the CDW intrusion well corresponds to the large isopycnal diffusivity. Bottom: schematic of relationship between the eddy flux and CDW intrusion. Continental slope topography controls the barotropic PV field and thus the horizontal structure of subpolar recirculating gyre and intrusion sites.
