Another cool and sunny morning at the wharf and a small bait ball was hanging out near the sampling area. Net tow was similar to last week – mostly detritus/debris and low phytoplankton biomass and diversity. The assemblage shifted a little and was mostly Tripos/Ceratium this week. No Pseudo-nitzschia or Alexandrium were observed.
