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 …

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.

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 …
