Big Bertha - Adventures in Zooplankton Sampling
Big Bertha is a specially designed plankton sampling pump that allows us to collect plankton from marinas where we can't used more traditional methods. We are using Big Bertha to collect zooplankton from bays with major commercial ports, a known source of introduced marine species, and smaller bays without a direct route for invasion overseas. We hope to document changes in the zooplankton community and detect new invasive species. We hope to estimate where the “hot spots” of invasive species occur and determine if management strategies, such as ballast water treatment, are helping to reduce new invasions. Full Story
