Sublethal Stress In Escherichia-Coli - Function Of Salinity, I. C. Anderson, Mw Rhodes, H Kator

VIMS Articles

Sublethal stress in Escherichia coli was detected in various test media after exposure (in vitro) to seawater of various salinities. Stress was measured with an electrochemical detection technique and a,-galactosidase assay. Test media included EC medium, medium A-1, and tryptic soy broth modified to contain lactose for /?-galactosidase assay experiments. Stress was defined as the difference between a predicted electrochemical response time calculated for unstarved cells from a standard curve and the observed electrochemical response time for cells starved in seawater. The higher the salinity, the greater the stress for all test media examined. Stress was most pronounced in EC …

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. …

Report Of Sampling Conducted In Chuckatuck Creek On Leased Grounds Near The U.S. 17 Bridge, Dexter S. Haven, Paul C. Kendall

Reports

This report conveys the results of a study of certain leased oyster grounds in the vicinity of the US 17 Bridge across Chuckatuck Creek. The study was made by the Virginia Institute of Marine Science and School of Marine Science of the College of William and Mary for the Department of Highways and Transportation, Suffolk, Virginia. Purposes of the study were to: 1) provide a description of the shellfish resource prior to construction of a new, wider bridge; 2) estimate the value of the oysters and shell on leased areas within the right-of-way; and, 3) provide a basis for a …

Survey Of Vegetation And Elevational Relationships Within Coastal Marsh Transition Zones In The Central Atlantic Coastal Region : Final Report, John D. Boon, Donna M. E. Ware, Gene M. Silberhorn

Reports

This report contains the findings of a one-year botanical field study of the marsh to uplands vegetational transition zone at selected sites within the Central Atlantic Coastal Region of the United States. The latter region is herein defined to include the coasts of Delaware, Maryland, Virginia, and North Carolina. To obtain results representative of the various coastal environments and associated wetlands types found within this region, five primary sites and one to four secondary sites in the vicinity of each primary site were chosen for detailed investigations.

Applications Of Remote Sensing To Estuarine Management : Final Report And Annual Report Number 7, John C. Munday, Hayden H. Gordon

Reports

Remote sensing techniques have been applied to problems in estuarine management in the seventh and final year of a NASA grant. A chromaticity technique for multi-date Landsat measurement of suspended sediment has been verified and made operational, and applied to sedimentation analysis of the ·Bay of Fundy Tidal Power Project. Dye-buoy photogrannnetry has been used to measure currents at depth and analyze suspended sediment plumes from hydraulic · dredging. Wetland permit sites and beach erosion site's have been evaluated with aerial photography. Submerged aquatic vegetation has been mapped with tide- and wind-synchronized color photography. Virginia state resource monitoring needs have …

Distribution And Abundance Of Submerged Aquatic Vegetation In The Lower Chesapeake Bay, Virginia, Robert J. Orth, Kenneth A. Moore, Hayden H. Gordon

Reports

The distribution and abundance of submerged aquatic vegetation (SAV) in the lower Chesapeake Bay and its tributaries were delineated with color aerial photography and surface information. Over 8500 hectares of SAV were identified on 31 topographic quadrangles. To enable computer retrieval of the aerial resource information, all information from the 1978 mapping effort was entered into a data base based on the Universal Transverse Mercator coordinate system.

The greatest concentrations of SAV were found at the mouths of the largest tidal rivers and creeks along the Chesapeake Bay shoreline, and to the east of Tangier and Great Fox Islands. Freshwater …

Reports

The purpose of this report is to: (1) suggest reasons for the recently observed cownose ray predation on Rappahannock River oyster beds and the apparent increased abundance of the ray, and (2) recommend short- and long-term methods to control and/or manage cownose ray predation on commercially important sh1ellfish beds.

Vims-Blm Second Order Wave Climate Model And Wave Climatology Of Baltimore Canyon Trough Shelf Area, Victor Goldsmith

Reports

The Wave Climate Model of the Baltimore Canyon Trough Shelf area encompassing the designated lease blocks was extended, refined, and comparisons made with real wave data, as part of this year's contract (Figures 15-la and 15-lb). This modified model w.as produced to refine the 1975 model so that more definitive statements and interpretations could be concluded, based on more detailed data, in the evaluation of the baseline data. A set of computer-generated graphics utilizing a greater depth data point density (0.25 NM), to al.low site-specific evaluation of conditions within the lease block area, were produced.

Middle Atlantic Outer Continental Shelf Environmental Studies Volume 1: Executive Summary, E. M. Burreson, H. J. Knebel

Reports

Increasing demand for petroleum and natural gas in the United States has led to a need for development of reliable new domestic sources. The Outer Continental Shelf of the United States holds great interest among the oil companies for possible exploration and development of oil and gas resources to meet this need. This interest was demonstrated for the Middle Atlantic Outer Continental Shelf in the oil companies' response to the lease sale conducted in August 1976. Of the 154 tracts comprising 876,750 acres offered for lease in August 1975 for exploratory drilling in the Baltimore Canyon Trough (Figure 1), oil …

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 …
