Cool and sunny at the wharf this morning. Detritus/debris increased in the net tow this week and phytoplankton biomass decreased. The assemblage remains mostly diatoms and Skeletonema and Chaetoceros were the most abundant. Pseudo-nitzschia were seriata-size and chains were shorter (~5c cell length). P. australis counts decreased by half from last week. No P. multiseries or Alexandrium were detected.
