Fall 2008 Update: Subregion Comparison of Chlorophyll

Charts of Bloom types

The intensity of winter blooms show little time series trend. These bloom periods are associated with low chlorophyll levels in the northern subregions, but they are important periods of primary productivity in the Southern New England and Middle Atlantic Bight areas. Spring bloom chlorophyll intensity shows a slight trend of increasing levels in the Gulf of Maine and Georges Bank over the past decade. The provisional 2008 chlorophyll intensity data is largely in line with levels that have been observed in past years.
