Cool, windy, and clear at the wharf this morning.  Phytoplankton biomass was similar to last week.  Diatom abundance and diversity increased this week and the net tow was an even mix of diatoms and dinoflagellates.  Tripos (Ceratium) and Chaetoceros were the most abundant.  Pseudo-nitzschia were mostly delicatissima size, but there were a few seriata size cells.  No Pseudo-nitzschia were detected in the probed counts, but Alexandrium cells were counted.

The wharf this morning was sunny with clear skies. There were lots of sea lions swimming at my site. The surface of the water was covered with small glimmering fish. It was a little hazy along the horizon. The water this week was greener than last week with less visibility (2.5m) in the water column. Chlorophyll visually increased from last week. Dinoflagellates dominated the water column. Akashiwo was abundant. Prorocentrum was common. Chaetoceros, and Pseudo-nitzschia delicatissima were present.

The wharf this morning was foggy and cloudy. However, while I was sampling the fog lifted and the colorful sky peeked through the clouds. The surface water glimmered with small silver fish and was wavy. The water this week was the same color as last week with a visibility of 3.5m. Chlorophyll decreased from last week (visually from the net tow RAI). Dinoflagellates dominated the water column. Akashiwo, Prorocentrum and Ceratium were common.

While our intrepid sampler Hannah is off on a research cruise, her back-up (Holly) went to the wharf this morning. Waters were flat. There was 100% overcast and an early drizzle. The net tow population had lots of Protoperidinium and quite a bit of Ceratium (apologies, only a HAB-centric RAI was performed this week) – Hannah will be back next week with full assessments. The visibility this week was 3.0m. The HAB species that were observed in the water this morning included Pseudo-nitzschia, Dinophysis, Akashiwo, Alexandrium, and Cochlodinium.

Beautiful and sunny morning at the wharf.  Bait ball still hanging around the sampling area.  Phytoplankton biomass increased this week.  Net tow remains mostly dinoflagellates with very few diatoms observed.  An unknown dinoflagellate was that most abundant this week.  No Pseudo-nitzschia were detected in the probed counts, but Alexandrium is back.

The wharf this morning was warm and sunny with a few wispy clouds! There was a slight breeze with small ripples on the surface of the water. The water this week was a slightly darker green than last week with a visibility of 5.0m. Chlorophyll decreased from last week. Diatoms dominated the water column. Pseudo-nitzschia delicatissima was abundant (>= 50%). Akashiwo was common (10 – 49%). Pleurosigma, Protoperidinium, and Dinophysis were present (1 – 9%). The HAB species that were observed in the water this morning included Pseudo-nitzschia, Alexandrium, Dinophysis, Cochlodinium, and Akashiwo sanguinea.
