Benthic Macroinvertebrate Population Distributions In Relation To The C. P. Crane Power Plant Thermal Discharge : Final Report, Robert A. Jordan, Charles E. Sutton, Patrica Goodwin

Reports

Benthic macroinvertebrates (0.5 mm sieve) were sampled quarterly during the period June 1979-April 1980 in the oligohaline habitat in the vicinity of the C. P. Crane Generating Station, and in three reference areas in tributaries of Chesapeake Bay. Communities were distinguished according to sediment type (sand vs mud groups) and water depth (creek vs river-bay assemblages).

Heavy Metal Inventory Of Suspended Sediment And Fluid Mud In Chesapeake Bay, Richard Harris, Maynard M. Nichols, Galen Thompson, John Banacki, George Vadas

Reports

Heavy metals have been found associated with suspended material, sediments and fluid mud in the Chesapeake Bay. A series of field observations were made along the Bay axis to determine the metal concentrations and their distributions at relatively high and at average river inflow between March 27-April 9 and May 2-10, 1979.

Metal concentrations in suspended material per unit volume of water relate to the concentrations of suspended material. They are higher in the zone of the turbidity maximum than landward in river water or seaward in estuarine water. Thus, metals associated with suspended material tend to accumulate in the …

Zooplankton Of The Waters Adjacent To The C.P. Crane Generating Station, George C. Grant, Cathy J. Womack, John E. Olney

Reports

Zooplankton populations in the Gunpowder River and its tributaries were sampled monthly from July 1979 to March 1980 in a continuation of similar studies begun in March 1979. Fourteen stations were sampled for mesozooplankton (202 ~m nets); six of these stations were also sampled for microzooplankton (concentration of pumped samples on 76 ~m netting).

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. …

The Virginian Sea Bibliography, Thomas M. Armitage, William J. Hargis Jr.

Reports

The bibliography of the Virginian Sea is a compendium of literature and environmental data concerning the Middle Atlantic Bight region of the Western North Atlantic - or the United States east coast. The geographical coverage of this bibliography ineludes that region extending from 41° N latitude to 36° N latitude and out 200 miles from the coastal headlands. This volume represents the first step of an effort undertaken by the Virginia Institute of Marine Science to assess the present status of knowledge concerning the physical and chemical environment, biology, and fisheries of the Virginian Sea. We do not put forth …
