Overcast and cool at the wharf this morning. Water was calm and clear and the bait ball was under the wharf, but not in the sampling area. Overall phytoplankton biomass decreased this week, but there were more of the larger sized cells in the net tow. Diatoms were the most abundant with a lot of diversity. Chaetoceros and Pseudo-nitzschia were the most abundant this week. Pseudo-nitzschia were both seriata and delicatissima size and Alexandrium counts decreased this week.
