Warm and sunny at the wharf this morning. The large bait ball was still hanging out under the wharf and in the sampling area. There was a decrease in phytoplankton biomass and the large cells (diatoms and dinoflagellates) dropped out of the assemblage. The unknown flagellate (maybe Heterosigma?) was the most abundant. Pseudo-nitzschia were delicatissima size.
