Spring 2013 Update: Fall Zooplankton Biomass Northeast Shelf Ecosystem
The biomass of zooplankton finished the year at below average levels for ecosystem, which continues the pattern seen in recent years. Spring zooplankton biomass has been at or above the long-term average, possibly a result of the advance in timing of the spring bloom. Fall zooplankton biomass is then below average. The cause of low fall zooplankton is uncertain but may have consequences for a number of species that depend on zooplankton for prey.
