Variability of Dinophysis acuminata blooms in False Bay. (A) Seasonal occurrence depicted as a composite of weekly means, and (B) interannual variability depicted as the mean daily concentration. Both (A) and (B) are derived from the collection of daily phytoplankton samples from Gordon’s Bay from 1992 to 2006. Numbered weeks run from first week in January to the year end (adapted from Trainer et al., 2010). DOI: https://doi.org/10.1525/elementa.367.f7
