^aThe peak of the bloom is defined as the date when maximum phycocyanin concentrations occurred.

^cThe severity of bloom events was defined by the concentration of phycocyanin (µg/L) at the peak of the bloom event. Mild = <150, Moderate = 150-500, Severe = >500.

^bDominant taxa detected at the peak of the bloom event. ND = Not determined, None = no dominant taxa representing >20% relative abundance.
