The Present State Of Organic Xenobiotics In The Chesapeake Bay - A Synthesis Paper, R. J. Huggett, R. H. Bieri, P. O. Defur, W. G. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This manuscript discusses the results of the first two and one half years of a three-year study designed to determine the present state of xenobiotic compounds in the Chesapeake Bay. It shows that polynuclear aromatic hydrocarbons are the most frequently encountered compounds and are the most abundant. Concentrations are highest in the Northern Bay with several sources implicated. During this study an apparent dumping of the pesticide, DDT, occurred. Either the quantity disposed of was small enough or the assimulation capacity was large enough that no adverse effects were noted. The detection by us of 6-phenyldodecane in bottom sediments of …

Water Quality In A Small Tidal Creek: Parker Creek, Virginia, Carl F. Cerco, Albert Y. Kuo

Reports

Parker Creek is a branched tidal creek located on the Eastern Shore of Virginia. In its southern branch, the creek receives waste inputs from a poultry processing plant. A study has been conducted to determine the effects of these inputs and to formulate a mathematical model of the creek system suitable for water quality planning. The model and field studies show the creek may be divided into two zones, an upstream zone dominated by freshwater flows and waste inputs, and a downstream zone dominated by conditions in adjacent Metomkin Bay. In the upstream zone of the waste-receiving branch, conditions of …

A Study Of Dredging Effects In Hampton Roads, Virginia, Walter I. Priest Iii

Reports

The intent of this report is to identify and quantify, in part, the adverse effects associated with the dredging operation itself and those segments of the ecological community which might be adversely affected by the levels of suspended solids and sedimentation attributable to the dredge. It consists of three sections including: a comprehensive review of the major marine resources, their location in and utilization of the Hampton Roads Harbor and vicinity; the turbidity model and physical environment, describing the levels and distribution of suspended sediment and sedimentation and local current patterns; and a review of the effects of increased suspended …

Investigation Of Hydrodynamic And Behavioral Factors That Affect Zooplankton Sampling By Pumps, Fred Jacobs, Albert Kuo, George C. Grant

Recreational Boating In Virginia: A Preliminary Analysis, Thomas Murray, Jon A. Lucy

Reports

Increasingly, recreational boating and its supporting industries are being affected by governmental policy and regulatory and allocation decisions. Clearly, those charged with making these decisions cannot understand the impacts of their decisions on related business, individuals, and their livelihoods without possessing some knowledge of the general linkages between boating and local economies. This initial estimate of the economic impacts of boating in Virginia is a first step in that direction. Hopefully, a better knowledge of the nature, recent growth and present magnitude of boating in the Commonwealth will insure that decisions made which influence its existence will be'based on the …

Experimental Colonization Of Crude Oil Contaminated Sediments By Benthos On The Middle Atlantic Continental Shelf, Donald Boesch, Eugene Burreson, Et Al

Reports

In August 1979 six arrays of defaunated sediment were deployed at each of three sites in the Middle Atlantic Outer Continental Shelf. Three arrays at each site had Prudhoe Bay crude oil mixed with the sediment. Because of technical difficulties recovery was limited to one control and one oiled array from two sites--one near the shelf break and one in a mid-shelf swale--after 10 months in situ. Moderate to severe sediment erosion occurred in boxes recovered from the mid-shelf. Chemical analyses indicated that between 50 and 90 percent of the added oil remained in the sediments after 10 months and …

Continuous Plankton Records : Zooplankton And Net Phytoplankton In The Southern Regions Of The Middle Atlantic Bight, 1978-80, Cathy E. Meyer, Herbert Austin

Reports

The Virginia Institute of Marine Science (VIMS) is currently providing logistical and scientific support to the Atlantic Environmental Group's Ship of Opportunity program in accordance with a VIMS/NOAA service contract. This program includes a Continuous Plankton Recorder - Expendable Bathythermograph (CPR/XBT) survey along a standard transect off the Chesapeake .Bay. Analysis of biological and physical data for this particular route is being processed by VIMS according to the standardized procedure set forth by NOAA and the Institute for Marine Environmental Research (IMER) of the United Kingdom.

Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki

Reports

Entrainment of the hydroid (Sertularia argentea) and the fleshly bryozoan (Alcyonidium verrilli) in the sea suction of deep draft naval vessels (carriers) in the area of the Norfolk Naval station has been a recurring problem since the early 60's. These fouling organisms (the term fouling is used in this report to indicate clogging of hull bottom intake grates and cooling system condenser tube sheets and not the growth of organisms on any part of the vessel) are winter species, growing only in the fall and winter and not the summer. Unfortunately they are also the most abundant and widely distributed …

Summary Of Sea Turtle Research In Virginia During 1979 And 1980: Final Report For Nmfs Contract #80 Fac 00004, John A. Musick

Reports

Directed research on the status of sea turtles in Virginia has been carried out by VIMS personnel since May 1979. Our efforts in 1979 (supported in-house) primarily comprised a documentation of sea turtle mortalities in the state. This. work was expanded somewhat in 1980 thru a small Fellowship Stipend from N.M.F.S, to support the thesis work of Molly Lutcavage. In 1980 Molly analyzed the 1979 mortality data, continued to monitor strandings, and began a tagging program in cooperation with selected poundnet fishermen. Also in 1980 we began an evaluation of sea turtle nesting in Virginia with the support of another …
