Nets like these are used to collect phytoplankton and zooplankton samples.

The phytoplankton component evaluates information collected at 12 Bay mainstem and tidal tributary stations 14 times per year.  Phytoplankton are a critical component of the Bay ecosystem and represent the first biological response to the Bay’s nutrient enrichment problem.  It is the overgrowth of algae that has led to the Bay’s low oxygen problems.  Results are used to show the success of Bay cleanup efforts, explain important linkages between water quality and living resources, and provide an early warning of potentially harmful exotic species.
