This morning it was misty and cloudy on the wharf. There was a slight breeze in the air. Two sea lion kept me company this morning. The surface of the water had small rolling waves. The water this week was the same color as last week with a visibility of 4.5m. Diatoms dominated the water column. Pseudo-nitzschia was abundant in the water. Meanwhile, Chaetoceros was common in the water. The HAB species that were present in the water this morning included Pseudo-nitzschia, Alexandriu, Dinophysis and Akashiwo sanguinea.
