Intensified turbulent mixing in the boundary current system of southern Greenland
Current (DWBC) advects major components of North Atlantic Deep Water. Turbulent diapycnal mixing rates of 104 m2 s1 commonly occur in the DWBC. These diffusivities, estimated with an internal wave strain-based parameterisation, are independently confirmed by budgets of density and dissolved O2. ‘‘Mo...
