Inner Shelf Sediments Off Chesapeake Bay. I - General Lithology And Composition, Maynard M. Nichols Jan 1972

Inner Shelf Sediments Off Chesapeake Bay. I - General Lithology And Composition, Maynard M. Nichols

Reports

The sedimentary materials and bottom topography of more than 2400 square miles of the inner continental shelf floor north off the Chesapeake Bay entrance have been surveyed for potential mineral resources. Sediments consist of two principal types: (1) fine sand and (2) medium to coarse sand. The fine sand is grey-colored, subrounded, rich in quartz and relatively 11clean 11 and well sorted. The medium-coarse sand is typically iron-stained, rich in shell and poorly sorted. The fine sand covers inner parts of the shelf floor whereas medium to coarse sand covers seaward parts. Additionally, shell-rich medium to coarse sand occurs on ...

Under this broad requirement, we have been specifically assigned the task of recommending an ocean-dumping policy for the Commonwealth. This paper, a survey of specially designated areas in coastal waters of the state, is designed to provide some of the background material required in the development of such a policy.


The Design Of The Monitoring System For The Thermal Effect Of The Surry Nuclear Power Plant On The James River, R. L. Bolus, S. N. Chia, C. S. Fang Oct 1971

The Design Of The Monitoring System For The Thermal Effect Of The Surry Nuclear Power Plant On The James River, R. L. Bolus, S. N. Chia, C. S. Fang

Reports

The demand for electric power in the United States is expected to double every 10 years. As hydroelectric power plant sites reach their full capacity, the demand for electricity will be met by the development of fossil fuel and nuclear power plants. The average thermal efficiency of nuclear power plants is presently about 32%. Therefore, a significant amount of heat is not utilized. For large power plants, the once-through cooling method, in which water is withdrawn from an adjacent body of water and returned after being heated, is the most common one. However, the great amount of heat discharged into ...

Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph

Reports

Our goal in assembling this bibliography has been to bring together literature references on all aspects of scyphozoan research. Compilation was begun in 1967 as a card file of references to publications on the Scyphozoa; selected references to hydrozoan and anthozoan studies that were considered relevant to the study of scyphozoans were included. In 1968, a major research program on the jellyfish of Chesapeake Bay was initiated at the Virginia Institute of Marine Science (VIMS) under Dr. E. B. Joseph, and work on the bibliography became an integral part of the program. In 1969 we began converting the bibliography into ...

Treatment Of Shell With Polystream To Increase Survival Of Oysters (Crassostrea Virginica) In Virginia, Dexter S. Haven, James P. Whitcomb Jan 1969

Treatment Of Shell With Polystream To Increase Survival Of Oysters (Crassostrea Virginica) In Virginia, Dexter S. Haven, James P. Whitcomb

Reports

Survival of oysters set on shells treated with Polystream* was investigated during 1963 and 1964. Treated and control shells were held in wire bags in the high-salinity intertidal seaside area of the Eastern Shore and in the moderate-salinity subtidal areas of the lower James River. Significantly more spat survived on treated shells than on controls. Differences in survival could not be attributed to absence of drill predation on treated shell.


Special Report To Oyster Industry: Growing Oysters In Msx Areas, Virginia Institute Of Marine Science Sep 1968

Special Report To Oyster Industry: Growing Oysters In Msx Areas, Virginia Institute Of Marine Science

Reports

MSX is a microscopic parasite that kills oysters but is not harmful to humans. It is a protozoan, or one-celled animal which thrives in areas of high salinity water. Death of oysters occurs mostly in the warm season with minor losses occurring in winter. MSX is now in its tenth year in Virginia with no reduction of its activity.

Reports

Reasonable progress has been made toward attaining the objectives of this project (No. 3-7-R). Considerable additional and new knowledge of the physical structure and dynamics of a theoretically horizontally-stratified estuary and the movement of the larvae and setting (spatfall) of juvenile Crassostrea virginica has been developed. Sedimentary processes, flushing times and the spatial and temporal distribution of the biological entities have also been investigated. Of especial interest have been the design, construction and verification of an hydraulic model of the system and the use of this scientific device to simulate movement of larvae by dye and to make 11time of ...


The 1963 Chesapeake Bay Fish Mortalities With Notes On Other 1963 Chesapeake Bay Mortalities (Notes On 1964 Fish Kills Are Also Included), William J. Hargis Mar 1965

The 1963 Chesapeake Bay Fish Mortalities With Notes On Other 1963 Chesapeake Bay Mortalities (Notes On 1964 Fish Kills Are Also Included), William J. Hargis

Reports

The literature, minutes of conference, data reports and other records, pertaining to the 1963 Chesapeake Bay fish kills has been reviewed in detail. Data concerning the few 1964 fish kills in Virginia waters are also appended. The various theories concerning the cause(s) of the kills have been carefully examined. All evidence indicates that the fishes killed, died as a result of interaction between unfavorable environmental factors and, in most species, bacterial disease (protozoan disease in 1964). Among the likely environmental stresses involved were: 1) severe hydroclimate, rapidly changing temperatures, high salinities due to drought, 2) low and high oxygens ...


Effects Of River Flow Regulation By Salem Church Dam On Marine Organisms, J. D. Andrews Nov 1964

Effects Of River Flow Regulation By Salem Church Dam On Marine Organisms, J. D. Andrews

Reports

This report is concernen primarily with the effects on oysters and some of their associates of hydrographic changes that would be caused by the dam. Other marine organisms are certain to be affected in ways only vaguely preceived at present. The distribution and activity of oyster drills and certain diseases of oysters, such as those caused by MSX and Dermocystidium, are regulated annually or at intervals of several years by low spring salinities and high summer and fall salinities.
