Four days of beautiful sunny, wind and fog free weather have contributed to a 2 oC rise in water temperature at our locale. The phytoplankton community has responded accordingly with net chlorophyll biomass increasing dramatically since last week ( ca. 14x to 2.40 ug/L net; ca 1.5x to 14.88 ug/L total by in vivo fluorescence). Diatoms were largely absent from the samples and the community was dominated by a mixed Ceratium spp bloom (53,931 cells / L total). This group was joined by Lingulodinium polyedra (6,195 cells / L), Gonyaulax spinifera (4,373 cells / L), Dinophysis spp (2,186 cells / L, a 11.5x increase) and Prorocentrum micans (1,822 cells / L).
