Before we discuss specific features,  here is a blow-up of the area around the moorings (A1-A3, and B1-B3) and Marguerite Bay. You can see that the currents are usually quite weak except for the coastal current, and the northward currents along the shelf break.

The flow seems to go into Marguerite Bay in the north and  exit in the south.  This circulation is consistent with the paths of near-surface drifters (drogued to 15 m depth: Beardsley and Limeburner, WHOI) and with a numerical model of the coastal circulation (Klinck, ODU).
