Oceanographic Data Collected In The Chesapeake Bight Of The Virginian Sea From 1966 Though 1969, E. P. Ruzecki, J. J. Norcross, F. J. Wojcik

Reports

This report is intended to make unsynthesized oceanographic data readily available to the scientific community. 3 Similar reports are envisioned which will include physical, chemical, biological and geological data collected by personnel of the Virginia Institute ·of Marine Science in areas of the continental shelf, and coastal zone to include beaches, wetlands, estuaries and tidal rivers - areas in which the Commonwealth of Virginia has a vested interest.

Groundwater Flow In A Sandy Tidal Beach 2. Two-Dimensional Finite Element Analysis., C. S. Fang, S. N. Wang, W. Harrison

VIMS Articles

Two-dimensional finite element techniques are described that model closely the complicated fluctuations osbserved in the water table of an ocean beach. The use of triangular elements permits the specification of more realistic boundary conditions than the use of line elements in a one-dimensional model. Also, results obtained from the two-dimensional model for the region closet o the ocean compare more favorably with field data than results obtained from the one-dimensional finite element model.

Bahamas Bibliography : A List Of Citations For Scientific, Engineering And Historical Articles Pertaining To The Bahama Islands, Carol Fang, W. Harrison

Reports

Specialized bibliographies are sometimes needed in connection with the research studies being pursued at the Virginia Institute of Marine Science. The Bahamas Bibliography arose out of the needs of marine geologists, biologists and physical oceanographers engaged in studies of beaches, fishes and inlet currents in the Bahama Islands. Although the present bibliography may suffer from completeness, it significantly surpasses in number of citations the only other known bibliography of like kind.

Effect Of Increasing Depth On Salinity In The James River Estuary, Maynard M. Nichols

VIMS Books and Book Chapters

The effects of channel deepening on the salinity and density flow in the James River estuary, Virginia, were studied to predict changes that might affect oyster production. A hydraulic model with 1: 1,000 horizontal and l: 100 vertical scales was employed to integrate three-dimensional changes in salinity and velocity through reaches of variable bottom geometry. After natural characteristics of the tide, current, and salinity were reproduced in the model, tests were run at three levels of steady river inflow, before and after a 3-meter channel deepening. Results were combined with corollary field observations to evaluate changes in present-day ecological conditions. …

Sediments Of The James River Estuary, Virginia, Maynard M. Nichols

VIMS Books and Book Chapters

The James River estuary of the Chesapeake Bay region follows the course of a former river valley drowned within the last 9,000 years by the most recent rise of sea level. The floor is shaped into a central channel bordered by submerged shoals. Observations show suspended sediment is transported mainly by alternating tidal currents and secondarily by the net nontidal estuarine circulation. Transport results in a sequence of grain size distributions reflecting the mixing of two textural end members, clay and sand.

Silty clay is deposited in the river and upper estuary, whereas sand occurs near the mouth. Transitional types, …

Acute Toxicity Of Unbleached Kraft Mill Effluent (Ukme) To The Oppossum Shrimp, Neomysis Americana Smith, Fred Jacobs

Dissertations, Theses, and Masters Projects

96-hour TL50 values of unbleached kraft mill effluent (UKME) for Neornysis arnericana were found to range from concentrations of 3.29 to 6.85% at 26-28 C and 3.90 to 7.30% at 16-18 C. Differences between batches of effluent proved insignificant in experiments at each temperature regime. Furthermore, UKME did not lose its toxicity, when stored for 5 to 7 days at 4 C. A concentration of 20% effluent killed 100% of the organisms in 8 of the 12 bioassays. Slope functions and confidence limits of TL50 were calculated. This dissertation is from the Joint Program Degree from the College of William …

Distribution, Growth, Selective Feeding, And Energy Transformations Of Young-Of-The-Year Blueback Herring, Alosa Aestivalis (Mitchill), In The James River, Virginia, Richard Greig Burbidge

Dissertations, Theses, and Masters Projects

Energy transformations and budget are computers for young-of-the-year blueback herring, Alosa aestivalis, in the James River, Virginia. Distribution, growth, and selective feeding are described. Fish and zooplankton collections were made at five stations in the main channel of the James RIver from June through November 1969. Two 24hr series of samples were collected in July and October 1968 in the Potomac River. A direct relationship existed between standing cropos of zooplankton and distribution, growth, and feeding of blueback herring. Zooplankton densities were highest upstream, where food consumption and growth rates were correspondingly highest. A progressive downstream decrease and upstream increase …

The Reproductive Cycle And Larval Tolerances Of Rangia Cuneata In The James River, Virginia, Thomas David Cain

Dissertations, Theses, and Masters Projects

The autecology of the brackish water clam Rangia cuneata was investigated in the James River, Virginia, from February 1970 to January 1972. The reproductive cycle, combined salinity and temperature effects on embryos and larvae, and setting were studied. Histological slides were made, set collected, and temperature and salinity measurements taken from three populations living in different salinity regimes. Phases of gonad development are described. Gametogenesis started in April and from May through September clams were found in all gonadal phases. Ripe gonads were found from May to late November with no summer or inactive period. It was determined by the …
