The panel recommends disapproval of proposal as presented.

This work contains the following themes as they relate to the Chesapeake Bay: The Living Natural Bay/Ecosystems, Environmental Stewardship and Sustainability of the Bay/Stewardship

The purpose of this document is to present a geographical targeting approach for focusing chemical contaminant remediation, reduction, prevention, protection, and assessment actions within the Chesapeake Bay basin.

This report is an overview of the background, fishery dependent and independent monitoring of the fisheries, research, regulations, and enforcement of the 1989 Striped Bass FMP during 1993/1994.

Recommendations on the reauthorization of the National Invasive Species Act specially dealing with Ballast Water Issues in Chesapeake Bay.

The Chesapeake Bay Environmental Model Package (CBEMP) was used to assess the environmental benefits of a ten-fold increase in native oysters in Chesapeake Bay. The CBEMP consists of a coupled system of models including a three-dimensional hydrodynamic model, a three-dimensional eutrophication model, and a sediment diagenesis model. The existing CBEMP benthos submodel was modified to specifically represent the Virginia oyster, Crassostrea virginica. The ten-fold oyster restoration is computed to increase summer-average, bottom, dissolved oxygen in the deep waters of the bay (depth > 12.9 m) by 0.25 g m-3. Summer-average system-wide surface chlorophyll declines by 1 mg m-3. Filtration of phytoplankton from the water column produces net removal of 30,000 kg d-1 nitrogen through sediment denitrification and sediment retention. A significant benefit of oyster restoration is enhancement of submerged aquatic vegetation. Calculated summer-average biomass improves by 25% for a ten-fold increase in oyster biomass. Oyster restoration is most beneficial in shallow regions with limited exchange rather than in regions of great depth, large volume and spatial extent.

The attenuation of light underwater is an important process in estuaries, directly affecting phytoplankton, submerged aquatic vegetation (SAV), visually orienting predators, and indirectly affecting oxygen depletion and other water quality indicators.
