|The right plot
now shows vectors from 3 different cruises
(the mooring and fall cruises) at 100 m.
|A strong coastal
current is evident in the plot. The
three cruises seem to agree fairly well.
The presence of a strong coastal current also agrees with WHOI
|The locations of
4 CTDs from the NBP-0103 cruise are shown on the right hand plot as blue dots
potential density and temperature/salinity at the 4 stations are shown on the
left. The T-S plot shows that the
surface water in the coastal current is warm relative to the outside world:
the 2 station closest to the coast (15 and 16: in the current) have much
different surface water properties than adjacent stations (14 and 17). The
lateral gradient of potential density (upper-left) across the current
suggests a surface-intensified current, consistent with the ADCP and the
strong southward drift of WHOI near-surface drifters.
