There was a slight breeze on the wharf this morning. The sky was filled with clouds and mist. The water was relatively calm. There were many fishermen at my site. The water this week is greener than last week with a visibility of 3.75m. Chlorophyll significantly increased from last week. Ceratium was abundant. Meanwhile, Ditylum and Prorocentrum were present in the water. The HAB species that were observed in the water this morning included Pseudo-nitzschia, Alexandrium, Dinophysis, Cochlodinium, and Akashiwo sanguinea.
