WHOI scientists Dennis McGillicuddy and Ruoying He created a computer simulation of the historic 2005 toxic algae bloom in New England. Red denotes high algae concentrations; blue the lowest. Algal cells germinated from cyst beds in the Bay of Fundy and along the Maine coast. They were swept south and west by currents. McGillicuddy and He entered a range of factors into their model: the speeds and directions of ocean currents, water temperature and salinity, winds, surface heat exchanges, tides, river runoff, and the distribution and behavior of cells in the water and in seafloor sediments.
