A Study Of The Effects Of Dredging And Dredge Spoil Disposal On The Marine Environment: Project Report., Virginia Institute Of Marine Science
A Study Of The Effects Of Dredging And Dredge Spoil Disposal On The Marine Environment: Project Report., Virginia Institute Of Marine Science
Reports
The Rappahannock Shoal and spoil disposal area investigated encompasses an area of approximately 180 square miles. The initial sampling program (1961) consisted of the establishment of a series of transects across the survey area. One hundred sampling stations were located along the established transects.
Inasmuch as the texture of the bottom sediments varied distinctly from place to place within the mid-bay region, the initial objective was to delineate the sediment distribution. Ninety-eight core samples were taken from the area with a modified Phleger coring device and analyzed in detail for textural characteristics. Representative stations were chosen and core samples were …
Report To The York River Oyster Research Corporation On The Physiological Response Of Oysters To Several Polymeric Materials And Their Derivatives, Dexter S. Haven
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 …

Heavy Metals Tolerance Limits : Terminal Progress Report, M. L. Brehmer
Reports
The toxicity of .metal ions Lo fresh-water organisms has received considerable attention but little is known regarding their effects on estuarine and marine forms. These studies were initiated to aid in the evaluation of marine pollution problems.

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 …
