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 …

Surface Observations, Ground Truth And Data : Nasa-Usgs Mission 144 : Chesapeake Bay Region, Sept. 22-30, 1970, Maynard M. Nichols

Reports

Surface observations of coastal waters and "ground. truth" data were obtained to aid interpretation and analyses of overflight photography and imagery. Among the broad objectives of the mission was to investigate the potential of high-altitude, multispectral photography as a tool for the improved planning necessary to cope with multidisciplinary problems within the coastal zone, specifically with regard to:

1. The inventory and evaluation of the central Atlantic coastal area natural resources;

2. The assessment of human and natural degradation of these resources;

3. The feasibility of monitoring resource allocation and management, including land use categories and the impact of urbanization …

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 …

The Effects Of Thermal Shock And Chlorine On The Estuarine Copepod Acartia Tonsa, David Michael Dressel

Dissertations, Theses, and Masters Projects

Acute bioassays were conducted to determine the effects of thermal shock and chlorine exposure on the estuarine copepod Acartia tonsa. Laboratory conditions simulated power plant conditions using 8 C elevated temperatures and slug chlorination. A factorial design having temperatures at two levels and multiple chlorine additions, showed isolated effects of temperature and chlorine and their interaction. Adult Acartia tonsa withstood thermal shocks of 8 C above ambient summer temperatures of 20 to 25 C. No adverse effects were noted after 96 hours following an 8 ⃤ T over 5 seconds, holding at the elevated temperature for 5 minutes, and slowly …

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 …

The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass

Reports

Gammarid amphipods of three tidal rivers entering Chesapeake Bay were studied for ten months, particularly in the York River where 40 species were record during the period. Several species moved up or down the rivers with changing salinity. The more abundant species had longer breeding seasons. The number of described species from lower Chesapeake Bay is now 42 and the presence of 10 undescribed species and of several which bracket the region indicates that much remains to be learned about amphipods in the Bay. Nineteen of these have a boreal affinity and seven are limited to the Virginian subprovince. A …

Hydroids And Hydromedusae Of Southern Chesapeake Bay, Dale Calder

Reports

A survey was made in southern Chesapeake Bay and its tributaries from April 1965 through March 1968 to determine the species of hydrozoans present, their seasonality and reproductive periodicities. This report discusses 43 hydroid and 27 medusa species known from the study area, of which 23 hydroids and 11 medusae have not previously been found in Chesapeake Bay. Clytia paulensis and the hydroid of Moerisia lyonsi have not been reported before in North American waters, and the hydroid of Amphinema dinema is recorded for the first time from the western Atlantic. The present records extend the northern range of one …

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

Dissertations, Theses, and Masters Projects

Three concentrations of cornstarch, 0 . 6 ppm, l.l ppm, 4.0 ppm, were fed to clams and mussels during the spring, summer, and fall of 1970 . Parameters measured were shell length, shell thickness, total weight, wet meat weight, and percentage glycogen based on wet meat weight. Starch had no effect on size parameters but did influence glycogen content of meats . Mussels showed an increase of glycogen in all three seasons . Clams showed an increase only in the fall. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia …

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 …

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 …
