Spring 2015 Update: Conditions of the Northeast Shelf Ecosystem

Fall Bloom Start Day and Magnitude

Fall blooms have been most frequently detected in the Georges Bank, Gulf of Maine and Scotian Shelf regions. In 2014, blooms were detected in Georges Bank and Gulf of Maine only.

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).

The Georges Bank bloom was among the largest bloom in terms of the bloom magnitude index; however, it was a not a particularly early bloom. The Gulf of Maine bloom was an average bloom both in terms of size and timing.
