Overcast at the wharf this am with scattered rain in the area. Bait ball was around the wharf (but not directly in the sampling area) and lots of birds in the area (mostly Pelicans this am). Phytoplankton biomass was about the same this week, but shifted to smaller cells. Dinoflagellate abundance and diversity both increased this week and an unknown flagellate was the most abundant.
