The progression of fall chlorophyll concentrations for the months of July through December are shown in the interactive figure. Chlorophyll concentrations appear as progressive shades of green in the top row icons. Anomalies of chlorophyll concentration, those tending to exceed plus or minus one quarter of a standard deviation of the overall concentration for the field, are in the bottom row set of icons. This type of anomaly tends to highlight strong blooms in an area, the green shades, and weak blooms in an area, the brown shades. A large fall bloom developed off the coast of New Jersey during July into August and appears to have dissipated by September. The Gulf of Maine bloom can be seen off the Maine coast in September and October and was restricted spatially to the inshore area. The Georges Bank area was in bloom condition during October and November.
