Water temperature declined monotonically by a degree since last sampling. Phytoplankton community biomass hit a new low (Net Fraction: ca 0.31X at 0.016 ug/L chl; Total: ca 0.56X to 1.49 ug/L by in vivo fluorescence). Of the sparse biomass, dinoflagellates were slightly dominant. Dinophysis tripos was present (198 cells/L) along with several Ceratium species. Eggs and dividing embryos were abundant along with sediment and detritus.
