Engineering works and the tidal Chesapeake

The tidal tributaries of the ocean and coastal areas of the mid-Atlantic region and the ecological significance of engineering projects are discussed. The effects of engineering works on maritime environments and resources, with the Chesapeake Bay as the area of prime interest are examined. Significant engineering projects, both actual and proposed, are described. The conflict of navigational demands and maintenance of an estuarine environment for commercial and sport fishing and recreation is described. Specific applications of remote sensors for analyzing ecological conditions of the bay are included

Histopathological analyses of tissue sections of the eyes of indigenous species of marine/estuarine and estuarine fish

The Elizabeth River is the most heavily settled and industrialized major subestuary in Virginia\u27s Chesapeake System. Under increasing use and development since around 1610, its\u27 waters have been exposed to all types of domestic, agricultural, military and industrial contaminants. ....Its sediments are contaminated by heavy metals, PAHs and all other introduced materials that accumulate and are stored there, with or without chemical transformation.... Collection of fish began in the Elizabeth River in the summer of 1982

Final report on results of Operation James River; an evaluation of the physical and biological effects of the proposed James River Navigation Project

A comprehensive study of the physical and biological characteristics of the James Estuary has been carried out by oceanographers of the Virginia Institute of Marine Science under contract with the Virginia Commission of Fisheries. This research project, under way for three years, has been directed especially to the effects of the proposed James River Navigation Project channel dredging on physical features--i·~.,the structure and dynamics, of the estuary, and indirectly on oyster production. Five separate phases were carried out under the project (called Operation James River). These involved: 1) accumulation and study of relevant literature and data, 2) research into the physical characteristics of the James, itself, 3) studies of oysters and related organisms in the field, 4) research on relevant marine organisms under laboratory conditions, and 5) studies of before and after effects of channel dredging on the salinity and currents in the especially-constructed hydraulic model. OJR has produced much new knowledge of the biological, chemical, geological and physical characteristics of the tidal James which is of great value scientifically and also will be of value in the future development of the James River Basin. Of greater immediacy, the physical studies indicate clearly that the proposed channel deepening will cause changes in the salinity and current regimes of the estuary. Biological research, however, shows that these physical changes will have no significant effect on the production of seed or market oysters in the James Estuary. If conducted properly, the dredging will not affect other marine populations significantly. Future proposals for alterations in the physical, chemical and geological characteristics of tidal James should be evaluated just as carefully
