Sunny and warm this morning at the wharf.  Net tow was mostly dinoflagellates, but phytoplankton biomass decreased slightly this week.  The phytoplankton assemblage shifted a bit as well and Akashiwo were the most abundant.  Oxyphysis were also a larger part of the community this week, which was unusual.  Alexandrium counts decreased an order of magnitude.  Pseudo-nitzschia were seriata size, but P. australis and P. multiseries were not detected in the probed counts.

Overcast/marine layer at the wharf this morning.  Phytoplankton biomass decreased this week and the net tow remains mostly diatoms.  Eucampia once again was the most abundant, but there was a visible increase in Akashiwo.  The Pseudo-nitzschia assemblage shifted a bit and were mostly delicatissima size this week.  P. multiseries counts decreased (2 orders of magnitude) and Alexandrium counts decreased as well.
