Another foggy and cool morning at the wharf. Net tow was mostly detritus/debris this week. Diatom and dinoflagellate biomass was low this week with few cells, but a lot of diversity. Overall phytoplankton biomass was similar to last week with cluster flagellates being the most abundant. Pseudo-nitzschia were delicatissima size.
