Fall 2012 Update: Spring Zooplankton Biomass - Northeast Shelf Ecosystem
The biomass of zooplankton started the year at above average levels for ecosystem, which may in part be a reflection of the advance in timing of the spring bloom. Then during the spring bloom, zooplankton levels were also above average. In the early summer, zooplankton returned to an average state. These data support the trend observed over the past 1-2 years, with above average zooplankton in the spring and below average zooplankton in the fall.
