Cool with a marine layer at the wharf this am, bait ball still hanging out in the sampling area.  Net tow was mostly detritus/debris this week with a decrease in phytoplankton biomass and diversity.  Phytoplankton assemblage was mostly dinoflagellates and Margalefidinium (mostly doublets) were the most abundant.  Alexandrium counts decreased again.

On the wharf this morning the sky was filled with clouds and the visibility was hazy. However, I was able to identify the horizon. There was a slight breeze on the dock and one fisherman was sampling beside me. The surface water had relatively calm waves. The water this week was slightly greener and lighter than last week with a visibility of 5.5m. Chlorophyll increased from last week with P. nitzschia being the most abundant species.

The wharf was busy this morning with fishermen. Sampling occurred during the slack tide. Barnacles were exposed and covered the wooden pillars of the dock. Cloud coverage was minimal. A blue sky hovered directly above me. Directly across from my sampling site there was a platform boat working underneath the dock. There was a slight breeze/wind causing ripples on the surface of the water. The water color was a darker green than last week and visibility increased to 6.5m. Chlorophyll increased compared to last week with Pseudo-nitzschia and Chaetoceros being the most common species present.

The sky was mostly clear. Only toward the horizon were there wispy clouds. The sun was rising from the east. Many birds accompanied me during sampling. Similar to last week, two sea lions greeted me. The water was very calm and there was no wind. The color of the water was slightly lighter and greener than last week. However, visibility in the water column decreased by ~2.5 m compared to last week (6.5 m). Chlorophyll abundance significantly decreased from last week. California is currently experiencing a heat wave. Chaetoceros decreased in abundance. Pseudo-nitzschia abundance was observed as rare and decreased from last week.

It was partly cloudy near the horizon this morning. There was seaweed near our sampling site, a couple jellyfish, and a friendly California sea lion. The sun was rising from the east and peaking through the cloud coverage. There was no fog inshore or offshore. The color of the water was similar to last week. However, there was a lot more visibility in the water this week (6.5m) compared to last week (3m). Chlorophyll abundance stayed relatively the same as last week. There was a bloom of Chaetoceros. Pseudo-nitzschia abundance increased from last week. Alexandrium, Dinophysis, Cochlodinium, and Akashiwo all appeared in the sample.

Heavy marine layer this am.  Bait ball was in the sampling area and lots of birds feeding.  Net tow was mostly dinoflagellates and phytoplankton biomass was about the same.  Ceratium and Margalefidinium were the most abundant.  The Alexandrium counts increased significantly this week, lots of 4-cell chains zooming around.

It was overcast with a slight drizzle at the wharf this morning. The water was still dark but slightly greener compared to last week. Visibility remained at 3 m. Lots of seaweed present at site and clogged the net. Chlorophyll increased compared to last week, with a significant increase in dinoflagellate abundance and diversity, however, diatoms remained dominant in the sample. Pseudo-nitzschia, Alexandrium, Dinophysis, Cochlodinium, and Akashiwo all appeared in the sample.

Overcast at the wharf this am with scattered rain in the area.  Bait ball was around the wharf (but not directly in the sampling area) and lots of birds in the area (mostly Pelicans this am).  Phytoplankton biomass was about the same this week, but shifted to smaller cells.  Dinoflagellate abundance and diversity both increased this week and an unknown flagellate was the most abundant.
