Notes:
When combined together, these studies have provided the team with a broad coverage of the entire South Bay. Our approach to the studies of the physical and chemical environment used existing scientific data supplemented by a project specific data collection as input to predictive computer models, including the MIKE 21 series of models developed by the Danish Hydrolic Institute, the TRIM 2D and 3D models, and the U.S. Army Corps of Engineers ADDAMS series of models for dredging effects on water quality and sediments. Our studies of the biological environment included the following approaches -- direct toxicity to aquatic organisms were studied based on published dose responses and the results of the water quality modeling. A food web model was used to estimate toxic effects to upper trophic level receptors. Physical biological predictive models were used to project phytoplankton and photosynthetic rate and biomass. And, finally, physical and chemical modeling results were combined with existing scientific data and professional experience to estimate effects on mackerel invertebrates, fish birds, and marine mammals.
I would now like to introduce Mr. Lou Armstrong, who will present the hydrodynamic and sedimentation sections.
