Preliminary Evaluation Of Water Quality In Tidal Creeks Of Virginia's Eastern Shore In Relation To Vegetable Cultivation, Mark W. Luckenbach, Morris H. Roberts Jr., Keith Boyd

Reports

In response to concerns raised about the impacts of vegetable cultivation using plastic ground covers on water quality, we have initiated a broad-scale, systematic study of water quality in seaside tidal creeks of Virginia' s Eastern Shore. Our objective was to determine if acute toxicity associated with heavy metals or pesticides was more prevalent in tidal creeks with drainage areas which include this agricultural practice than in those which do not. Though such correlations do not confirm cause and effect, they may serve as the basis for future, more targeted investigations and for some immediate changes in land management practices …

Ecological Study Of The Tidal Segment Of The James River Encompassing Hog Point (Site Of The Surry Nuclear Power Station) : Completion Report, Robert A. Jordan, Patrica A. Goodwin, Charles E. Sutton

Reports

The Surry Power Station discharges cooling water into the transition zone of the James River. Phytoplankton, zooplankton, benthos, and fouling organism communities were sampled during the years 1969 through 1978, which encompassed a preoperational and an operational period. Temporal changes in the biotic communities followed seasonal patterns of temperature and salinity in the study area, and reflected inherent reproductive patterns of the organisms. Spatial patterns reflected the transport of organisms from the river in the vicinity of the intake to the zone encompassed by the discharge plume, as well as periodic bursts of meroplankton generation in the cooling water canals. …

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …

Special Purpose Areas In Virginia's Coastal Zone, J. B. Pleasants

Reports

The Virginia Institute of Marine Science is charged with the responsibility of advising state management agencies on matters relating to the environments and resources of the coastal zone of Virginia. Under this broad requirement, we have been specifically assigned the task of recommending an ocean-dumping policy for the Commonwealth. This paper, a survey of specially designated areas in coastal waters of the state, is designed to provide some of the background material required in the development of such a policy.
