Spring 2014 Update: Fall Bloom Start Day and Magnitude
Fall blooms have been most frequently detected in the Georges Bank, Gulf of Maine and Scotian Shelf regions, though that pattern of bloom frequency was not observed in 2013. The time series figures for these regions show the start day of detected blooms (black circles) and bloom magnitudes for both detected blooms (large blue circles) and climatological bloom magnitudes for years where a bloom was not detected (small blue circles).
A bloom was detected in the Gulf of Maine and in the composite Northeast Shelf chlorophyll signal. In the other areas, Georges Bank, Scotian Shelf and the Middle Atlantic Bight, no fall bloom was detected. The 2013 Gulf of Maine fall bloom was relatively early and the second largest magnitude fall bloom in the time series.
