On Basin Hyposmetry And The Morphodynamic Response Of Coastal Inlet Systems, John Boon, Robert J. Byrne Jan 1979

On Basin Hyposmetry And The Morphodynamic Response Of Coastal Inlet Systems, John Boon, Robert J. Byrne

Reports

The exchange of water and entrained material between coastal basins and the inner continental shelf reduces to the problem of polarized transport (flood +, ebb —) in the conveyance channels routing flow through a coastal inlet. Here the net long-term movement of materials is largely a function of the fluid velocity and discharge — variables whose time history at-a-station contains both periodic and aperiodic elements. In this paper the importance of the major periodic elements in coastal inlet flows and their potential contribution to the net transport of bedload materials is discussed.

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz Jan 1979

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 …


A Survey Of The Late Summer Benthos Community In The Vicinity Of The C. P. Crane Generating Station, Robert A. Jordan, Charles E. Sutton, Patrica A. Goodwin Jan 1979

A Survey Of The Late Summer Benthos Community In The Vicinity Of The C. P. Crane Generating Station, Robert A. Jordan, Charles E. Sutton, Patrica A. Goodwin

Reports

A survey of the sediment distribution in the vicinity of the C. P. Crane Generating Station, Bengies, Maryland showed that the sediments in the creeks receiving the plant's cooling water discharge were predominantly soft clayey-silt. The benthic invertebrate taxa found in these sediments were typical of the connnunities found in oligohaline waters of Chesapeake Bay. Comparisons of the benthic community in the discharge area with the connnunities in two reference areas of similar sediment type revealed an apparent reduction in the discharge area population of the dominant amphipod, Leptocheirus plumulosus, in August.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1978 Annual Summary, Dexter S. Haven, Paul C. Kendall Jan 1979

Oyster Spatfall On Shellstrings In Virginia Rivers: 1978 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.


Estuarine Fluid Mud : Its Behavior And Accumulation, Maynard M. Nichols, Richard Faas, Galen Thompson Jan 1979

Estuarine Fluid Mud : Its Behavior And Accumulation, Maynard M. Nichols, Richard Faas, Galen Thompson

Reports

A study of fluid mud in Virginia estuaries was conducted to determine how the mud accumulates in a dynamic tidal flow regime. The mud occurs as lenses and blanket deposits in zones of fast sedimentation, i.e. on channel floors and in the turbidity maximum zone. Viscosity measurements indicate resuspension potential of the mud is greater in the turbidity maximum than elsewhere.
