| Figure 3. Satellite image of phytoplankton abundance derived from ocean color (average of OCTS for May 2 and 5, 1997); higher abundances are darker. Arrows show the average water velocity between 16 and 24 meters, measured by acoustic doppler current profiler (ADCP) on the Oleander. In May 1997, the Ocean Color and Temperature Sensor (OCTS) detected bloom concentrations of phytoplankton following the continental shelf break for more than 200km east of approximately 72.5°W; high abundances are represented by darker shades and the white contour shows the location of the shelf break.
