Fall 2007 Update: Subregion Comparison of Chlorophyll Magnitude
Bloom magnitude has increased for Gulf of Maine spring blooms over the ten year time series, reflecting a similar trend seen in the bloom intensity data for this subregion. The magnitude of Georges Banks spring blooms increased during the period 2001-2004; however, in recent years bloom magnitude has declined suggesting that the spring blooms on the Bank have been short duration and high intensity blooms, which can result in low magnitude blooms. There are no discernable trends in the winter blooms occurring in the Gulf of Maine, on Georges Bank or in the Southern New England subregions. The winter bloom in the Mid-Atlantic Bight has increased in magnitude over the time series.
