Seasonal Distribution And The Retention Of Some Decapod Crustacean Larvae Within The Chesapeake Bay, Virginia, Joseph William Goy

OES Theses and Dissertations

Planktonic stages or 45 genera and species or decapod larvae were identified and staged from samples taken over a three year period in the lower portion and entrance area or Chesapeake Bay. The distribution of each larval stage of the decapod crustaceans found in the bay was determined and from this, the extent of the respective breeding season was deduced. In 1975, samples were taken monthly from stations along a transect at the baymouth, both at the surface and bottom. Two stations were also occupied over the tidal cycle in daylight and darkness. Evidence is presented that larvae of some …

An algal culture chamber was constructed capable of providing controlled temperature (18 ± 2°C) and light (400-500 ft-c) conditions. Four parameters were used to describe the growth response of D. tertiolecta including maximum specific growth …

Numerical Simulation Of Thermohaline Convection In The Mixed Layer Of The Ocean, Victor Eli Delnore

OES Theses and Dissertations

The intradiumal heating and cooling cycle of the mixed layer of a tropical ocean is investigated through the use of a pseudo-two-dimensional numerical model. Particular emphasis is given to two-component diffusion resulting from dynamic instabilities in the water column. The conservation equations for salt and heat include the effects of solar heating, horizontal advectlon, and turbulent fluxes at the sea surface, while wind mixing enter through the use of depth-dependent eddy diffusion coefficients resulting from the wave-orbital shear model of KitaigorodsldLy. All inputs are treated as functions of time-of-day, or calculated via the bulk aerodynamic method.

The entrainment fluxes of …

Control Of Clay Mineral Distribution By Estuarine Circulation, James River Estuary, Virginia, Jean-Pierre Feuillet

OES Theses and Dissertations

A study was performed on the clay minerals of the James River estuary, Virginia, to determine the predominant factors that influence clay mineral distribution in the estuary. The factors of differential settling, flocculation, and diagenesis show minor or no effects on distribution, while estuarine circulation exerts the strongest influence upon the clay mineral distribution.

There are two clay suites in the James River estuary. The upper James River clay suite is a kaolinite, dioctahedral vermiculite, and mixed-layer suite, with kaolinite being the major mineral. The lower Chesapeake Bay clay suite is an illite, chlorite, and montmorillonite suite, with illite being …

A Numerical Model For The Prediction Of Tides And Tidal Currents In The Lafayette River, Norfolk, Virginia, G. Mcallister Sisson

OES Theses and Dissertations

A prediction technique for tidal heights and currents in the Lafayette River of Norfolk, Virginia has been formulated and tested by the implementation of a two-dimensional numerical model employing the Navier-Stokes momentum equations and conservation of mass. The model operates on a spatially-fixed rectangular grid system by utilizing a multi-operation finite difference scheme which employs implicit and explicit solutions to the aforementioned equations. Forces due to bottom friction and Coriolis are taken into account. The only open boundary considered in the model is the river mouth, across which tidal height is specified temporally. Collected tidal height and current data at …

Petrology Of The Oceanographer Fracture Zone (35ºn35ºw), Tsugio Shibata

Geology Theses and Dissertations

During a geological and geophysical survey of the Oceanographer Fracture Zone (35°N, 35°W), seventeen dredge hauls containing a variety of rocks were obtained. Petrographic study shows that these rock samples can be classified into six main rock types: fresh basalt, weathered basalt, metabasalt, gabbro, metagabbro, and serpentinite. Most of the dredge hauls were positioned on the steep, southern wall of the fracture zone, and an inference from the dredging results suggests that basalt is the most abundant rock type which outcrops at the junction between the rift valley and the fracture zone; however, as we move away from the junction, …

A Hydroclimatic Study Of The Narragansett Bay Drainage Basin: The Effects Of Climate And Urban Land Use On Runoff, Paul J. Jaillet

Theses and Major Papers

This study analyzes the relationship between the climate of the Narragansett Bay Drainage Basin and the increasing urban land use into a relative increase in runoff in the Basin streams. Data for thirty-five years were collected to discern the trends in runoff within the Basin. It was hypothesized that runoff is increasing in relation to an increase in urban acreage. Runoff data were analyzed in two forms. The Thornthwaite water budget was used to estimate runoff. For this, Basin temperature and precipitation records were necessary inputs. The estimated runoff was plotted against observed runoff by double-mass analysis. Deviations from the …
