Objective
This regional
observation and modeling program focuses on the Gulf of Maine and its
adjacent New England shelf waters. The overall
objective is to establish a comprehensive regional-scale understanding of Alexandrium fundyense dynamics,
transport pathways, and associated shellfish toxicity and to use this
information and relevant technologies to assist managers, regulators, and
industry to fully exploit nearshore and offshore shellfish resources
threatened by PSP, with appropriate safeguards for human health.
Approach
The program will utilize a
combination of large-scale survey cruises, autonomous gliders, moored
instruments and traps, drifters, satellite imagery and numerical models
to: 1) investigate A. fundyense bloom dynamics and the pathways that link this
organism to toxicity in both nearshore and offshore shellfish in the Gulf
of Maine and southern New England shelf waters; 2) investigate the
vertical structure of A. fundyense blooms in the study
region, emphasizing the distribution of cells, zooplankton fecal pellets,
other vectors for toxin, and their linkage to toxicity in offshore
shellfish; 3) assess interannual to interdecadal variability in A. fundyense abundance and PSP
toxicity; 4) incorporate field observations into a suite of numerical
models for hindcasting and forecasting applications; and 5) synthesize results and disseminate the information and
technology, transitioning scientific and management tools to the
regulatory community for operational use.
