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 …

Landsat Analysis Of The Dynamics Of The Chesapeake Bay Plume On The Continental Shelf, John C. Munday, Michael S. Fedosh

Reports

The dynamics of the Chesapeake Bay plume have been studied by examination of 81 dates of Landsat images with color additive enhancement and single-band density slicing. The "plume" was interpreted from surface turbidity discontinuties as revealed in images from multispectral scanner (MSS) bands 4-7. Results show that the Chesapeake Bay plume usually frequents the Virginia coast south of the Bay mouth. Wind and tide vectors are the principal variables affecting the plume dynamics. Southwestern (compared to northern) winds spread and disperse the plume easterly over a large area. Ebb tide images (compared to flood tide images) show a more dispersed …

Tracing Kepone Contamination In James Estuary Sediments, Maynard M. Nichols, Norman H. Cutshall

VIMS Articles

The escape of Kepone into the James River estuary, Virginia, for more than nine years produced widespread contamination of the sediments with important ecological consequences. The pollutant extended seaward more than 100 km from its source and contaminated an estimated 31 million tonnes of sediment to depths of more than 60 cm. Kepone spread through the food chain and to every segment of the environment from marshes to the channel floor.

Kepone escaped mainly during high river inflow from a point source in freshwater tributaries. Near the source Kepone is associated with organic material but in the low er estuary …

Chesapeake Bay Bibliography - Volume V. Virginia And Maryland Waters, Marilyn Neff Loesch

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.

Development And Application Of An Index To Assess Nutrient Enrichment In Estuaries : A Report To The Chesapeake Bay Program, U. S. Environmental Protection Agency, Bruce J. Neilson

Reports

An index is 11 something used or serving to point out", "a guide", "a sign, token or indication" (.14) +. Indexes* such as those used in books, magazines and newspapers are not the subject of this study. Rather we are concerned with the use of indexes in technical fields. Even these are encountered often in everyday life. For example, a recent front-page newspaper article noted that "the government's index designed to forecast future economic trends dropped .... after rising for six straight months". An editorial column in the same issue addressed the use of "the existing Consumer Price Index as …

Nonpoint Sources And Impacts In A Small Coastal Plain Estuary: A Case Study Of The Ware River Basin, Virginia, Gary F. Anderson, Cindy Bosco

VIMS Books and Book Chapters

The Ware River Study is one of five small watershed projects sponsored by the EPA Chesapeake Bay Program. These projects are designed to provide data on nutrient and organic loadings entering the Bay over the wide range of topographies, climates, and land uses which occupy its watershed. Each provides information on a particular geographic segment of the Bay region. In particular, the Ware study is intended to document special characteristics of runoff from low relief coastal plain environments, and to document their impacts on a small estuarine receiving water.

Oyster Spatfall In Virginia Rivers: 1980 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine 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.

Effluent Travel Estimates From Ships Anchored In Chesapeake Bay : A Report To The Virginia State Water Control Board, C. S. Fang, C. S. Welch, T. J. Brooks

Reports

As the world demand for coal has increased, the number of colliers arriving at Hampton Roads, Virginia, to load coal has exceeded the ability of the port to supply the demand. As a result, a substantial backlog of ships waiting to load coal is presently taxing the anchorage capacity of the harbor. A recent estimate is that 130 ships are waiting about 38 days each for their turn at the loading factl1t1es. In addition to the anchorages tn Hampton Roads and the lower James River, new anchorages have been opened to accomodate these ships, one on the southern side of …

The Consequences Of Nutrient Enrichment In Estuaries, Bruce J. Neilson

Reports

A "paper study" was conducted to determine the consequences of nutrient enrichment in an estuary. First, a classification scheme was developed to assign- a "Level of Nutrient Enrichment" to a water body based on concentrations of Total Phosphorus and Total Nitrogen. The impacts of nutrient enrichment on the various uses of estuaries there were described and assessed. Finally, "safe" nutrient levels for Chesapeake Bay and its tributaries were recommended.

A Preliminary Study Of Community Oxygen Metabolism In The Vicinity Of The C. P. Crane Electric Power Generating Station : Final Report, Paul L. Zubkoff

Reports

The community metabolism of the waters in the vicinity of C. P. Crane electric power generating station is reported for two seasonal periods in 1979. The early autumn period (October) is generally characterized by warm water temperatures (20°C) and an insolation period of 11 hours; the late autumn period (December) is generally characterized by cold water temperatures (4-6°C) and an insolation period of approximately 9 hours. Both sets of observations, were taken during periods which were significantly influenced by winds. ... more.

Fate And Effects Of Experimental Oil Spills In An Eastern Coastal Plain Marsh System : Final Report, M. E. Bender, J. G. Hudgins, R. A. Jordan

Reports

The objectives of this program conducted over a four year period were to determine the ecological effects, chemical fate and microbial responses of marsh systems to crude oil spills. To conduct these studies in a manner which maximized control, large enclosures were constructed in a natural mesohaline marsh (Figure 1). Both fresh South Louisiana crude and artificially aged South Louisiana crude were studied.
