Assessment Of Mechanical Damage To Entrained Ichthyoplankton, Vepco Surry Nuclear Power Station, J. V. Merriner, A. D. Estes

Reports

Thermal plume ichthyopla~kton sampling during November and December 1976 was cancelled since Units 1 and 2 of VEPCO Surry Nuclear Power Station were non-operational due to refueling. In lieu of the thermal plume ichthyoplankton entrainment program, a sampling program to estimate mortality from mechanical damage was initiated.

Four sampling sites were selected for determination of quantity and condition of organisms entering and leaving the plant. Sites were selected at points preceding and following critical areas where the likelihood of damage was greatest. Net .sets were made using a 0.5 meter paired net apparatus. All sets were at bottom strata to …

Characterization Of A Historically Nutrient Enriched Marsh Ecosystem : Yorktown Creek, Yorktown, Virginia, R. L. Wetzel, M. S. Kowalski, W. M. Rizzo, A. Thompson, K. L. Webb

Reports

In this report, we summarize our initial findings of a nutrient enriched aquatic ecosystem prior to relaxation of sewage input. The studies reported were directed toward characterizing the system prior to relaxation and to begin 􀌣xperimental studies to accomplish our general objectives.

Environmental Effects Of James River Sewage Treatment Plant Outfall Construction, Dexter S. Haven, Paul C. Kendall, Robert J. Diaz, Donald F. Boesch, Michael E. Bender

Reports

In the spring of 1975 the Institute began a program to determine whether significant environmental changes would occur in the area of the new James River Plant outfall that might be related to its construction and/or initial operation. Parameters measured in the study were benthic animal and oyster populations, coliform levels and chlorine residuals. The primary emphasis of the study centered on the estimation of the impact of the construction activity on shellfish beds in the area. The results of the investigation are presented in three segments, the first dealing with shellfish populations, the second with other benthic animals and …

Ecological Effects Of Highways On Coastal Wetlands, Atlantic Coast Region, John D. Boon, George M. Dawes

Reports

A literature review of past and on-going research and activities of the principal investigators is the basis for evaluating environmental effects of highways in wetlands. Values of wetl8,$1ds are discussed briefly. Physical. biological and chemical impacts are associated with highway construction. operation and maintenance. Environmental impacts are scaled in terms of magnitude and duration and mitigating measures are identified. The foregoing are summarized in matrices. The report further identifies further research which is needed to design highway projects with environmental aspects in mind.

The Effect Of The Chesapeake Corporation On The Water Quality Of The Upper York River With Respect To Total And Fecal Coliforms And Fecal Streptococci, Martha Rhodes, Howard Kator, Nancy King

Reports

Levels of total and fecal coliforms and fecal streptococci in the Mattaponi, Pamunkey and York Rivers were monitored for one year in the vicinity of the town of West Point, Virginia. These parameters were also determined for selected process waste waters and effluents from the Chesapeake Corporation, West Point, Virginia.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1976 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of M3rine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur, Shells planted just before the period of maximum set have the best chance of getting a good strike,

Effects Of Petroleum Hydrocarbons On Salt Marsh Communities, Carleton H. Hershner Jr.

Dissertations, Theses, and Masters Projects

This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.

The effects of petroleum hydrocarbons on salt marsh grasses and gastropods were examined under three different circumstances. In the first study reported, a small pocket marsh was repeatedly dosed with small amounts of a No. 2 fuel oil. The second study investigated the effects of a large accidental spill of No. 6 fuel oil. The third study involved single doses of a fresh and a weathered crude oil on artificially enclosed segments of marsh.
