A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer

Reports

The City of Virginia Beach has proposed channel dredging in the Eastern Branch of the Lynnhaven Bay for the purposes of recreations and drainage improvement. It is therefore necessary to examine the possible environmental results of such a project. This environmental assessment is complicated by another proposal to modify the Lynnhaven system. The U.S. Army Corps of Engineers has proposed adding a second canal leading to the Eastern Branch, in order to reduce flood damage. This canal project would affect the Lynnhaven system by increasing nonpoint sources of pollution and by increasing the tidal prism. The water quality consequences of …

A Water Quality Study Of The Eastern Branch Of The Lynnhaven Bay, Virginia, Albert Y. Kuo, Paul V. Hyer

Reports

To alleviate the flooding in the drainage basin of the Lynnhaven River at Virginia Beach, Virginia, the U. S. Army Corps of Engineers has proposed to improve the waterways along the headwater of the river (House Document, 1976). The improvements include the widening and deepening of the existing canal, and the dredging of a new canal. As a result of the proposed project and the present rate of increase in area development, the freshwater runoff from the drainage basin and the tidal prism in the system are expected to increase. Since nonpoint sources are the only source of pollutants to …

A Description Of The Commercial Marine Fisheries Of Virginia, James Zaborski

Reports

The magnitude and valtte of the fisheries of Virginia are significant. Expansion of some fisheries since 1977 in conjunctio~ with rising prices for fishery products in general has increased the importance of this industry to the Commonwealth. Virginia's fisheries are varied, some segments of the industry such as the oyster fishery have been in existence since colonial days; others, such as the surf clam fishery, are relatively new. The size and composition of the different industries also differ widely. The menhaden fishery exempli~ies what might be termed corporate fishing while the blue crab fishery is conducted by numerous individual owner-operators. …

The Effects Of Sewage Pollution Abatement On Phytoplankton Productivity And Standing Crop In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

In September 1976, the City of Tampa initiated a comprehensive monitoring study of the ecology of the phytoplankton community of Hillsborough Bay. Numerous studies elsewhere have shown that phytoplankton are well suited as monitors of trophic state due to their rapid response to changing environmental conditions (Hohn, 1959; Williams, 1964; Margalef, 1968; Welch, 1968; Dunstan, 1975; Taslakain and Hardy, 1976). The present study is designed to relate changes in the phytoplankton community of Hillsborough Bay with the reduced nutrient load entering the Bay from the AWT facility.

Acute Biological Effects Of Chemically Dispersed Oil Spillage : Final Report To The American Petroleum Institute, George C. Grant, Howard I. Kator, Paul L. Zubkoff

Reports

Primary productivity, heterotrophic potential, chlorophyll i! and phaeophytin, ATP, and direct bacterial counts were measured in the sea surface layer under controlled spills of La Rosa and Murban crude oils following immediate dispersal with the EXXON dispersant, Corexit 9527. Tests were conducted off New York on November 9, 1978.

The response of productivity to dispersed oil appeared as an initial increase in rates, a reduction to minimal rates 1-2 hours after dispersion, and a return to pre-spill rates after 3 hours. Comparison of productivity measurements from the two tests suggested a more efficient and rapid dispersion of the somewhat lighter …
