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 2015, blooms were detected in all areas of the Northeast Shelf. 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 blooms were average size in terms of the bloom magnitude index, in most areas. With the exception of the early bloom in the Middle Atlantic Bight, bloom timing approximated the average in most areas.
