Sunny and cool this morning at the wharf with a bait ball and feeding sea lions near the sampling area. Net tow was mostly detritus/debris and diatoms were the dominant group. Phytoplankton biomass was low, but the chain forming diatoms were pretty happy looking. Chaetoceros was the most abundant. Pseudo-nitzschia were seriata-size, but none were detected in the probed counts.
