Storm-Wave And Storm-Surge Modification Of Virginia's Ocean Coast, Wyman Harrison

Reports

The purpose of this study was to begin work on a method for operational prediction of storm-induced beach changes. The thought was to use wind and storm-surge data that are predicted on a routine basis by the National Weather Service, NOAA, and it was felt that if such a procedure could be developed, it would be possible to provide estimates of beach erosion or deposition as part of routine weather forecasts whenever storms threatened. It was also hoped that it might be possible to make estimates of shoreline erosion during previous years by using historical storm data in the prediction …

Studies Of The Potential Curve Crossing Problem I. Analysis Of Stueckelberg's Method, W. R. Thorson, John B. Delos, Seth A. Boorstein

Arts & Sciences Articles

A detailed critical analysis is made of Stueckelberg's treatment of inelastic transitions at a crossing of two potential curves. Using an asymptotic method analogous to the WKB approximation, Stueckelberg obtained the well-known Landau-Zener-Stueckelberg (LZS) formula for the inelastic transition probability. His method involved the determination of "connection formulas" linking amplitudes associated with his asymptotic approximants on either side of the crossing-point region. Here we show that (a) Stueckelberg's asymptotic approximants are just the WKB approximants for elastic scattering on the adiabatic (noncrossing) potential curves; (b) Stueckelberg's method for obtaining the connection formulas can be put on a rigorous footing, including …

Effects Of Thermal Shock On Larvae Of The Oyster, Crassostrea Virginica (Gmelin), Robert J. Diaz

Dissertations, Theses, and Masters Projects

Larvae of the American oyster Crassostrea virginica (Gmelin) were subjected to thermal shocks of varying magnitude at different larval ages. The effects were assessed in terms of mortality, growth, and setting success. Growth of larvae acclimated at 25 C and 20% salinity was not affected by a thermal shock of 10 C or 15 C, but a 20 C thermal shock had detrimental effect on growth. Mortality of oyster larvae increased significantly following thermal chocks of 10, 15, and 20 C, and was higher for older than for younger larvae. Setting rates of the control and 10 C shocked larvae …

The Feeding Of Cornstarch To Clams And Mussels, Kathleen Rapier Harleston

Age, Growth, And Mortality Of The White Perch, Morone Americana (Gmelin), In The James And York Rivers, Virginia, Richard Alan St. Pierre

Dissertations, Theses, and Masters Projects

More than 750 white perch, Morone americana, were collected from each of two major tributaries of southern Chesapeake Bay to compare the age structures, growth rates, and mortality rates of the two populations.The James River is characterized by heavy domestic and industrial pollution, whereas the York River is only slightly polluted. Maximum ages determined by scale analysis were 7 and 10 years for males and females respectively in each river. Males and females from the James River were larger than those from the York up to ages IV and V, respectively. Older fish were larger in the York . Females …

Benthic Infauna Of Eelgrass, Zostera Marina, Beds, Robert Joseph Orth

Dissertations, Theses, and Masters Projects

The infauna of Zostera beds in the Chesapeake Bay-York River estuary and Chincoteague Bay was sampled in March and July using a corer. Sediments were fine sand or very fine sand. Sorting of sediments varied from poorly sorted to moderately well-sorted and was related to the density of Zostera at the respective stations. A total of 17 macroinvertebrate taxa was collected. Species abundance decreased up the estuary and there was a significant interaction in the number of species between stations and seasons. Faunal similarity of the areas sampled, as measured by three indices, indicated that the infauna of most Zostera …

Vertical Distribution Of Estuarine Phytoplankton In The Surface Microlayer And At One Meter, And Fluctuations In Abundance Caused By Surface Adsorption Of Monomolecular Films, Victoria R. Gibson

Dissertations, Theses, and Masters Projects

A quantitative comparison of the phytoplankton in the surface microlayer of an estuary and that a depth of one meter was made using a Garrett-type screen and a Frautschy bottle for sample collection. Results showed that the surface microlayer contained a significantly greater number of phytoplankton cells than the water at one meter. Species diversity at the surface tended to be somewhat lower than one meter, due to a greater number of individuals of the dominant species. Investigation revealed that the presence of a monomolecular film of slick material absorbed onto the water surface resulted in a decrease in the …

Groundwater Flow In A Sandy Tidal Beach 1. One-Dimensional Finite Element Analysis, W. Harrison, C. S. Fang, S. N. Wang

VIMS Articles

A 31-day time series of observations of beach water table and tidal fluctuations was obtained from 13 wells along a profile perpendicular to the shoreline at Virginia Beach, Virginia. Finite element techniques were applied to solve the one-dimensional, unsteady state, nonlinear equation for groundwater movement. For the finite element analysis, the semi-infinite mass (unconfined aquifer) had to be replaced by a finite mass. The boundary conditions were found from the field data by directly solving the flow equation with a finite difference technique. The finite element method, using the variational principle, provided a reasonable solution and afforded economy in computer …

Polychlorinated Biphenyls In The Elizabeth River : Final Report, Robert J. Huggett

Reports

For the past eight years, the Virginia Institute of Marine Science has been a participant of the National Pesticide Monitoring Program. Within the framework of this program, oyster samples have been collected from areas throughout the Chesapeake Bay.and analyzed for chlorinated hydrocarbon pesticides. The data from the last three years show that polychlorinated biphenyls (PCB's) are being concentrated by the eastern oyster, Crassostrea virginica. The highest concentrations found were always from one station, Hospital Point, in the Elizabeth River. Samples from this station, collected during the spring of 1971, contained residues of the PCB, Aroclor(R) 1254 of 2.8 ppm. For …
