Here’s a quick work up of the SWIFT drifts around Pt Sal from the previous few days.  The drifts are all southwards (releases are at the northernmost points for each track), and the color scale is the log10 of the TKE dissipation rate averaged over the upper 5 m.  Looks like there is a region of high dissipation were the flow separates around the headland and changes direction.
