Larval Dispersal of the Nonnative Zebra Mussel in the Saint Lawrence Estuary: A Modeling Study

This research will focus on the dispersal of zebra mussel veligers   in a particularly vulnerable and ecologically important region of   the SLE: the estuarine transition zone (ETZ). The physical-  biological computer model of the ETZ used for this research consists   of two parts: a circulation model and a zooplankton transport model.   The circulation model is a three-dimensional Eulerian hydrodynamic   model (TRIM3D) driven by the wind, tides, and freshwater outflow.   The zooplankton transport model is a three-dimensional Lagrangian   particle-tracking model, which simulates zooplankton movement in the   three-dimensional flow of the circulation model. The circulation   model is calibrated using hydrodynamic field data. Using this model,   the project will explore the physical and biological mechanisms that   control the transport and retention of zebra mussel veligers in the   ETZ. These results will ultimately help control the spread of this   and similar invasive species.    (aquatic invasive species); (AIS); (ANS); (aquatic nuisance   species); (zebra mussel); (zebra mussels); (Dreissena polymorpha);   (plankton); (zooplankton)
