Another sunny morning at the wharf. The net tow remains mostly dinoflagellates and the phytoplankton assemblage was similar to last week. However, the phytoplankton biomass decreased dramatically. Diatom diversity increased this week, but Akashiwo and Prorocentrum remain the most abundant. Pseudo-nitzschia were delicatissima-size and Alexandrium counts were similar to last week.
