This is a map of the mean ADCP currents on a ¼ x ¼ degree grid.

Data from all cruises have been used to create this grid.  The two colors represent current vectors at different depths (red 100, green 205 m).

It is important to remember that certain regions have more data going into them that others.  The southern portion of the grid is derived primarily from the NBP-0103 cruise.

There are 3 obvious features here: the southward  coastal current near Adelaide Island, the northward current at the shelf break, and this cross-shelf “jet” near 68.5 S.  The first 2 features will be discussed separately in the next few slides.

We can also see that there is, in some locations, significant depth-dependence in currents.
