Harmful Algae: maps of seasonal variation

Here, concentrations of Dinophysis spp., Chaetoceros convolutus and concavicorne, Heterosigma akashiwo, Dictyocha spp., Rhizosolenia setigera and Alexandrium plotted here on maps at the location of the measurement, separated into 3-month intervals for each year.  Multiple samples are available at each location in each of these intervals and the markers are semi-transparent to provide an indication of the different observed concentrations.
