A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer

Reports

The City of Virginia Beach has proposed channel dredging in the Eastern Branch of the Lynnhaven Bay for the purposes of recreations and drainage improvement. It is therefore necessary to examine the possible environmental results of such a project. This environmental assessment is complicated by another proposal to modify the Lynnhaven system. The U.S. Army Corps of Engineers has proposed adding a second canal leading to the Eastern Branch, in order to reduce flood damage. This canal project would affect the Lynnhaven system by increasing nonpoint sources of pollution and by increasing the tidal prism. The water quality consequences of …

A Water Quality Study Of The Eastern Branch Of The Lynnhaven Bay, Virginia, Albert Y. Kuo, Paul V. Hyer

Reports

To alleviate the flooding in the drainage basin of the Lynnhaven River at Virginia Beach, Virginia, the U. S. Army Corps of Engineers has proposed to improve the waterways along the headwater of the river (House Document, 1976). The improvements include the widening and deepening of the existing canal, and the dredging of a new canal. As a result of the proposed project and the present rate of increase in area development, the freshwater runoff from the drainage basin and the tidal prism in the system are expected to increase. Since nonpoint sources are the only source of pollutants to …

A Description Of The Commercial Marine Fisheries Of Virginia, James Zaborski

Reports

The magnitude and valtte of the fisheries of Virginia are significant. Expansion of some fisheries since 1977 in conjunctio~ with rising prices for fishery products in general has increased the importance of this industry to the Commonwealth. Virginia's fisheries are varied, some segments of the industry such as the oyster fishery have been in existence since colonial days; others, such as the surf clam fishery, are relatively new. The size and composition of the different industries also differ widely. The menhaden fishery exempli~ies what might be termed corporate fishing while the blue crab fishery is conducted by numerous individual owner-operators. …

Distribution And Abundance Of Submerged Aquatic Vegetation In The Lower Chesapeake Bay, Virginia, Robert J. Orth, Kenneth A. Moore, Hayden H. Gordon

Reports

The distribution and abundance of submerged aquatic vegetation (SAV) in the lower Chesapeake Bay and its tributaries were delineated with color aerial photography and surface information. Over 8500 hectares of SAV were identified on 31 topographic quadrangles. To enable computer retrieval of the aerial resource information, all information from the 1978 mapping effort was entered into a data base based on the Universal Transverse Mercator coordinate system.

The greatest concentrations of SAV were found at the mouths of the largest tidal rivers and creeks along the Chesapeake Bay shoreline, and to the east of Tangier and Great Fox Islands. Freshwater …

Middle Atlantic Outer Continental Shelf Environmental Studies Volume 1: Executive Summary, E. M. Burreson, H. J. Knebel

Reports

Increasing demand for petroleum and natural gas in the United States has led to a need for development of reliable new domestic sources. The Outer Continental Shelf of the United States holds great interest among the oil companies for possible exploration and development of oil and gas resources to meet this need. This interest was demonstrated for the Middle Atlantic Outer Continental Shelf in the oil companies' response to the lease sale conducted in August 1976. Of the 154 tracts comprising 876,750 acres offered for lease in August 1975 for exploratory drilling in the Baltimore Canyon Trough (Figure 1), oil …

Summary Of Shoreline Situation Reports For Virginia's Tidewater Localities, Carl H. Hobbs Iii, Dennis W. Owen, Lynne C. Morgan

Reports

This summary report marks the completion of the Shoreline Situation Report project. For over six years project team members with the Department of Geological Oceanography at the Virginia Institute of Marine Science have inventoried over 5,000 miles of shoreline in Tidewater Virginia. The methodology was developed and evaluated with funding through the Chesapeake Research Consortium, Inc. from the Research Applied to National Needs (RANN) program of the National Science Foundation. After preliminary evaluation as to its worth, the project became part of Virginia's Coastal Resources Management Program, supported by the Office of Conmerce and Resources with funds provided by the …

The Role Of Filter-Feeding Organisms In Concentration Of Suspended Solids Containing Kepone Into Bottom Deposits, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Filter-feeding marine animals such as molluscs, tunicates and barnacles filter particles as small as 1 micron from suspension during their feeding process and void them as fecal pellets. These settle at much faster rates than their component particles. Feces or pseudofeces which settle are termed biodeposits. Eighty-two to 93 percent by volume of the particles in the biodeposits of several species of molluscs are smaller than 4 microns; the range in size of those particles is about 1 to 10 microns (Haven and Morales-Alamo, 1973).

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 …

Sampling of spring 1979 plankton populations at the C.P. Crane site was conducted at 15 stations during six sampling periods for phytoplankton, at 5 stations monthly from March to June for microzooplankton and monthly at 14 stations for mesozooplankton. Ancillary physical data were collected at all the above stations, while nutrients were measured twice in April.

Community Structure Of Fishes On The Continental Slope And Rise Off The Middle Atlantic Coast Of The United States, John A. Musick

Reports

Otter trawl cruises were conducted off the middle Atlantic coast of the U. S. from 1971 to 1975. More than 50,000 specimens of demersal fishes were captured during this program at depths of 75 m to 3000 m. Species assemblages were distributed along a coenocline with bathymetric areas of rapid faunal change (anantoclines) and of more gradual faunal change (aganoclines). Between 75 and 3000 m anantoclines were found at 150 to 200 m, 400 to 600 m, 900 to 1000 m, 1350 to 1500 m, and 1900 to 2100 m. Species diversity (Hl) increased between the continental shelf and slope, …

Lower Bay Zooplankton Monitoring Program : An Introduction To The Program And Results Of The Initial Survey Of March 1978, George C. Grant, John E. Olney

Reports

The zooplankton of Chesapeake Bay occurs as two definable, seasonal populations: a summer-fall community, peaking in August, and a winter-spring assemblage, peaking in February or March (Grant 1977; Jacobs 1978). A minimum of two surveys per year are therefore required for long-term assessment of these communities: March and August have been selected as sampling months. Adequate assessment of meroplankton, particularly fish eggs and larvae and the larvae of decapod crustaceans, requires sampling over the principal reproductive period of June through August (Goy 1976; Olney 1978). Surveys for these components only are to be conducted in June and July, in addition …
