Tracking potential Harmful Algal Blooms

Animation in top right panel shows model output of the prior 2 and next 3 days of HABs position and concentration. Modelled and projected surface currents are used in combination with estimates of the extent of HABs from satellite imagery in a particle model capable of producing these forecasts. (See animation of surface currents from GLCFS)
