|Here we consider
the ADCP record of currents at the continental shelf break. Most data (blue)
come from a multi-day occupation of LMG-0104 Process Site #1.
|Vectors from 3
different cruises are shown in the above plot. They are at a depth of ~ 205 m. The summary of the data is:
|(1) The shelf
break current is generally northward at ~30 cm/s.
|(2) Peak speeds
are over the central slope. The current is at the edge of the Antarctic
Circumpolar Current (ACC). This can be seen from comparisons of the ADCP
records with hydrographic data from CTD.
|(3) There is
some evidence for an eddy at LMG-0104 Process Site #1.
drift at depth agrees with WHOI surface drifter tracks.
