Characterisation of mixing
The intrinsic measurement of the ADCP (and one which it makes very accurately) is of shear, at scales from 10s to 100s of meters, often termed the finescale or the internal wave band. One of the intriguing questions is the degree of mixing that occurs between the Red Sea Water and the Antarctic Intermediate Water (AAIW) within the Agulhas Current. Does the presence of salty intermediate waters enhance vertical mixing at mid-depths? We propose to characterize the mixing using finescale measurements and parameterizations of turbulent dissipation (Polzin and Firing, 1997; Polzin et al., 1995).
