* Impressions *
Sunny and cool at the wharf this morning. Phytoplankton biomass was similar to last week, but there was a dramatic increase in the detritus/debris in the net tow this week. Diatom diversity remains high and no genus was overtly abundant this week. Pseudo-nitzschia were seriata size and P. multiseries were detected in the probe counts. Alexandrium counts were the same as last week.
