Lower York River Dissolved Oxygen Study, Robert A. Jordan

Reports

Past studies of the lowerr York River have shown that dissolved oxygen (D .O.) concentrations decline in the summer months, occasionally falling one mg/ 1 near the bottom in deep water (Brehmer,1970; Jordan,1973) . Due to this apparently natural phenomenon the Virginia water quality standards for D.O. in estuaries (4.0 mg/1 allowable minimum, 5 .0 mg/1 minimum daily average, U.S.. E.P.A,1971), are not met during this period . Therefore additional waste-water discharges into the lower York River will not initiate violation of the standards, but may exacerbate the existing situation by extending the area and the time period affected by …

James River Sediment Study: Operation Agnes Final Report, John Lunz, Robert J. Huggett

Reports

Bottom sediment samples were collected from the James River in Virginia and analyzed to evaluate the effects of tropical storm Agnes (summer, 1972) upon the sediment chemistry . The results of these analyses, frcm hereon called "post Agnes data," were compared with data from a similar study carried out during the summer of 1971 ( "pre-Agnes data"), reported under contract no. DACW-65-71-C-00~7 .

The post Agnes samples encompass three distinct shoaling areas involving a total of 34. 75 nautical miles of the James River . The first area extending from mile 24. 75 to 33. 50 can be considered os …

On The Use Of Drift Bottle And Seabed Drifter Data In Coastal Management, Christopher S. Welch, John J. Norcross

Reports

The use of drift bottle and seabed drifter information for use in coastal management is discussed. The drift bottle/seabed drifter portion of VIMS project MACONS (Mid Atlantic Continental Shelf) is described as an example of how a comprehensive survey using drift bottles and seabed drifters provides data useful for coastal management. The data from MACONS are analyzed to answer specific questions of interest to several different coastal managers: a manager siting a deep oil port, one siting a sewage outfall, a manager responsible for setting up emergency beach protection procedures before an accident occurs, and a manager responsible for the …

Development Of The Turbidity Maximum In A Coastal Plain Estuary : Final Report, Maynard M. Nichols, Galen Thompson

Reports

A study of the turbidity maximum in the Rappahannock Estuary; Virginia was conducted to determine how high concentrations of suspended sediment accumulate to form a maximum.

Time-series observations of current velocity, salinity and suspended sediment over 8 to 18 tidal cycles reveal that the maximum forms in a convergence of bottom residual currents near the transition between fresh and salty water. Sediment supplied mainly by the river is transported into the convergence by density currents and accumulates since velocity is nearly zero and settling exceeds upward mixing.

The maximum forms in the middle estuary after freshet or flooding and shifts …

Geostrophic Currents And Gulf Stream Study For The Outer Continental Shelf Area Of The Atlantic Ocean From Sandy Hook, New Jersey To Cape Canaveral, Florida, Christoper S. Welch

Reports

This document is being prepared for the Council on Environmental Quality (CEQ) as a portion of the Virginia Institute of Marine Science (VIMS) response to the geostrophic current estimate portion of task 1 and task 5 of the contract. It consists of an estimate of mean geostrophic currents on the continental shelf of the East Coast of the United States between Sandy Hook, New Jersey and latitude 27°N. Also included is a surmmary of speeds of surface current in the Gulf Stream east of the area of interest.

In addition, the method of estimation for geostrophic currents is described and …

New Approaches To The Study Of The Circulation On The Continental Shelf, Paul V. Hyer

Reports

The current state of knowledge of continental shelf circulation is summarized . Existing data collections are reviewed for quality and quantity. Descriptions are given of possible advanced experiments utilizing remote sensing and buoy technology to study water exchanges between the shelf and Gulf Stream.

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.

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.

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 …

Utilization Of Physical And Mathematical Models In Marine Water Resources Research, Planning And Management : A Final Report, Willliam J. Hargis Jr.

Reports

During the period 1 September 1967 to 30 September 1969, Virginia Institute of Marine Science personnel were engaged in hydraulic model studies, mathematical and computer studies; and instrument and technique development. An investigation was made into the stability and reproducibility of an estuarine hydraulic model.

Studies were made of the dispension of point-source dye releases in an estuarine hydraulic model, and of the applicability of the results to the release of disease-resistant seed oysters.

Analytical studies were made of diffusion in estuaries and of the integro-differential equations for estuarine 'flow. Computer studies were made of two-dimensional estuarine circulation and of …

Hydrographic Data From The Atlantic Plankton Cruises Of The R/V Pathfinder, December 1959 - December 1960, Edwin B. Joseph, William H. Massmann, John J. Norcross

Reports

The data included in this report have resulted from a series of monthly offshore cruises conducted by the Ichthyology Research Section. The cruises were made to obtain information on the distribution and abundance of pelagic eggs and larvae of fishes. Since the biological results will be reported in a series of separate papers (Joseph, Massmann and Norcross, 1961), it was felt that the raw hydrographic data shpuld be made available in a single source.

The area covered is approximately 2500 square nautical miles of the neritic zone within the 20-fathom contour. The shore line encompasses the mouth of Chesapeake Bay …
