able to slow the vessel eight times for 15-20 min 
periods for net tows in order to collect zooplankton 
at three stations within and five outside the CCR for 
comparison with ADCP acoustic backscatter inten- 
sity data logged while these tows were made. The 
ADCP acoustic backscatter intensity data were col- 
lected according to the methods described by Flagg 
and Smith (1989) and Zhou et al. (1994). 
Figure 1 
Analysis of NOAA-12 advanced very-high-resolution radiometer satellite imagery of sea surface temperatures (SST) processed by 
Louisiana State University. Circles give the location of the 33 XBT stations; the numbers inside these circles designate where 
zooplankton tows 1-8 were made. Lighter grey shades represent lower SST; the CCR is visible as a region of locally cooler surface 
temperatures encircling XBT’s 10-17 (zooplankton tows 2-4). Arrowheads show the expected counter-clockwise circulation in 
CCR periphery.
