Ecological Survey, Upper James River, Surry Nuclear Power Station Site, August 1974, M. Bender, R. Jordan, M. Ho, M. Cavell

Reports

In May of 1969 field surveys to characterize selected biological communities in the Hog Island area of the James River were begun. The objective of these surveys has been to determine if significant changes occurred in the species composition or population levels of certain communities which could be related to the operation of the nuclear power generation station. Although during the period of study, methods and stations have been changed to adjust the study to changing regulations, its basic character has remained. Communities studied have included benthos, zoo- and phytoplankton and fouling organisms.

A Report On The Concentration, Distribution And Impact Of Certain Trace Metals From Sewage Treatment Plants On The Chesapeake Bay, Robert J. Huggett, O. P. Brickner, G. R. Helz, S. E. Sommmer

A Program To Monitor The Environmental Effects Of Shipyard Expansion : A Final Report, Robert J. Diaz, M. E. Bender

Reports

Dredging and land reclamation are two of the potentially most damaging activities that man undertakes in estuarine areas. Hampton Roads, the world's largest natural harbor, is a multiple use port, being a major center for fishing and shellfishing, transportation, recreation and industrial sitings. Dredging which is a necessary perpetuation for some of these activities, could be directly or indirectly detrimental to others. It is in such a multiple use situation that environmental alterations, real or potential, must be carefully planned and closely monitored. Projects of the type underway can cause changes in circulation, water depth, turbidity, and patterns qf siltation, …

Investigation Of Surface Films - Chesapeake Bay Entrance, William G. Macintyre, Craig C. Smith, Et Al

Reports

Experimental point source oil releases have been conducted in the Chesapeake Bay mouth area. Predictions of oil slick motion were tested, and slicks were sampled and analyzed to measure their aging rates over periods up to 32 hours. Remote sensing. techniques were used to detect and measure the spreading rate of oil. Some laboratory oil film aging experiments were done to further document and elucidate aging processes. Results indicate· a,reasonable motion prediction, an explanation of the non-biological initial aging of oil films, and a fair corroboration of a theoretical oil spreading model.

Polychlorinated Biphenyls In The Elizabeth River : Final Report, Robert J. Huggett

Reports

For the past eight years, the Virginia Institute of Marine Science has been a participant of the National Pesticide Monitoring Program. Within the framework of this program, oyster samples have been collected from areas throughout the Chesapeake Bay.and analyzed for chlorinated hydrocarbon pesticides. The data from the last three years show that polychlorinated biphenyls (PCB's) are being concentrated by the eastern oyster, Crassostrea virginica. The highest concentrations found were always from one station, Hospital Point, in the Elizabeth River. Samples from this station, collected during the spring of 1971, contained residues of the PCB, Aroclor(R) 1254 of 2.8 ppm. For …

Report To The York River Oyster Research Corporation On The Physiological Response Of Oysters To Several Polymeric Materials And Their Derivatives, Dexter S. Haven

Reports

The physiological responses of several polymeric materials and their derivatives, associated with the manufacturing process of pulp, were tested on oysters. It was thought that, when fed in small quantities, these substances might increase shell or meat size or be of value as possible nutritive supplements . The substances tested were divided into two classes. The first, consisting of basic polymeric materials, may occur in natural water s as the result of chemical changes. Representatives of these were indulin C and dextrose. The second class is composed of chemically pure derivatives of the preceding substances. These may appear in trace …

Concentration Of Suspended Radioactive Wastes Into Bottom Deposits., Dexter S. Haven

Reports

During recent years rapid advances in nuclear technology have increased the probability of accidental contamination of our coastal estuarine waters by several routes. The chances of such contamination appear remote, but in the event of a nuclear accident, it would be imperative to understand processes which will disperse or concentrate radioactive materials. In coastal waters the disposal or transport of radionuclides in concentrations exceeding the maximum permissible concentration is affected by tidal action and by the volume of inflowing fresh waters. During the period of transport by coastal or estuarine currents, physical and chemical forces will produce abiotic sedimentation. The …
