Sounder transects near Pt Sal

Here’s an example of the persistent southerly flow and separation that we have seen the last few mornings with the Sounder and Sally Anne (SIO whaler) running ADCP transects around Pt Sal.  Sally Ride is on this transect now, so we should soon see what this looks like during other phases of the tide.
