Sunny and warm at the wharf this morning.  There was a bait ball under the wharf as well as lots of CSL and bird activity.  Phytoplankton biomass decreased again this week and the net tow assemblage was mostly dinoflagellates due to a decrease in diatoms.  Alexandrium and Prorocentrum were the most abundant.  Pseudo-nitzschia were delicatissima size and there were noticeably less cells than last week.  No Pn were detected in the probed counts and Alexandrium cell concentration dropped by an order or magnitude.

The wharf this morning was warm and sunny. The surface of the water was calm but there was a slight breeze. Fog lined the horizon. Note: the phytoplankton samples were collected with a 50 uM mesh net this week. The water this week was the same color as last week with a visibility of 5.5m. Chlorophyll visually decreased from last week. Diatoms dominated the water column. Pseudo-nitzschia delicatissima was abundant. Thalassiosira was common. Chaetoceros was present. The HAB species that were observed in the water this morning included Pseudo-nitzschia, Alexandrium, Dinophysis, Cochlodinium, and Akashiwo sanguinea.

The wharf was still stuck in the marine layer this morning.  Phytoplankton biomass decreased again this week and the most noticeable change was the decrease in the unknown flagellate.  The larger cells remained an even mix of diatoms and dinoflagellates with Pseudo-nitzschia and Prorocentrum being the most abundant.  Pseudo-nitzschia were mostly delicatissima-size with a handful of the seriata-size chains.  No P. australis or P. multiseries were detected in the probed counts.  Alexandrium increased again this week with another dramatic jump in the cell counts.

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.
