A Study Of Leased Oyster Grounds Adjacent To The New And Old James River Bridges, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall, William C. Phoel Sep 1976

A Study Of Leased Oyster Grounds Adjacent To The New And Old James River Bridges, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall, William C. Phoel

Reports

'l'his report describes two studies by the Virginia Institute of Marine Science (VIMS) on oyster bottoms adjacent to the recently constructed and the original James River bridges. The first study was conducted from July to October, 1972, prior to construction of the new bridge. The second was carried out in April, 1976, after the new bridge was finished, but prior to the removal of the southern end of the original bridge.

There were several purposes to the studies: 1) To determine if construction activity had a measurable impact on the adjacent leased bottom; 2) To quantify the magnitude of ...


A Prototype Lagrangian Current Buoy Using The Carrier Plus Sideband (Csb) Retransmission Of Omega Navigation Symbols, Donald L. Baker, Christian S. Welch Jul 1976

A Prototype Lagrangian Current Buoy Using The Carrier Plus Sideband (Csb) Retransmission Of Omega Navigation Symbols, Donald L. Baker, Christian S. Welch

Reports

As part of the continental shelf investigations of the Virginia Institute of Marine Science (VIMS) , electronics were developed and tested to track an ocean-current-following (Lagrangian) buoy by the retransmission of Omega navigation signals to a shore station using medium frequency (2 . 398 MHz) ground wave propagation and equal-carrier-upper-sideband modulation . The buoy electronics include sharp clipping and filtering for noise reduction and Omega signal equalization . The carrier and upper sideband are transmitted with equal power to maintain the relative phases of separate Omega station signals on demodulation. The base station is a 2.4 MHz receiver/demodulator feeding a commercial Omega ...


Water Quality In The Small Coastal Basins, Bruce J. Neilson Jan 1976

Water Quality In The Small Coastal Basins, Bruce J. Neilson

Reports

The Small Coastal Basins portion of the Hampton Raods 208 study area includes the Back and Poquoson Rivers on the Virginia Peninsula and Little Creek Harbor and the Lynnhaven Bay system on the southern shore of Chesapeake Bay, as shown in Figure 1. The drainage areas are characteristically small, ranging from only 63 square kilometers for Little Creek Harbor to 156 sq. km,for the Lynnhaven Bay system. All four basins lie entirely within the geological Coastal Plain Province, the low lying area between the Fall Line and the Atlantic Ocean. The soft sediments typical of this province erode easily ...


Vims Statement Portsmouth Refinery, Virginia Institute Of Marine Science Jan 1976

Vims Statement Portsmouth Refinery, Virginia Institute Of Marine Science

Reports

With regard to the Proposed Final Environmental Impact Statement issued by the U. S. Army Corps for the Portsmouth Refinery and Marine Terminal , we shall comment on four subject areas which the statement discusses.· These are 1) the potential impact of new pollutant loadings in the lower James River, · 2) the potential impact of oil spills, 3) transportation risks and 4) the effects of dredging for the marine terminal. In addition, comments are included which address: 1) interagency communications regarding oil spills in the Bay region, 2) safety precautions taken during the transportation of oil by vessels in Bay waters ...

Fine Scale Circulation Near "Foxtrot" In Hampton Roads, Virginia, Christopher S. Welch, Bruce J. Neilson Jan 1976

Fine Scale Circulation Near "Foxtrot" In Hampton Roads, Virginia, Christopher S. Welch, Bruce J. Neilson

Reports

During 1974 the Virginia Institute of Marine Science conducted a series of oceanographic, water quality and modeling studies for the outfall from the proposed Nansemond Wastewater Treatment Plant (VIMS, 1975). One of these studies included dye releases to determine the dispersion and transport of material discharged to Hampton Roads near Pig Point. These dye releases were made from the munitions loading piers known as "Foxtrot".

The proposed outfall, as given in the Facilities Plan is located roughly one kilometer to the east-south-east of Foxtrot. Tidal circulation in Hampton Roads is quite complex and there was concern that the distribution patterns ...

Shoreline Situation Report Cities Of Chesapeake, Norfolk, And Portsmouth, Dennis W. Owen, Lynne M. Rogers, Margaret H. Peoples, Robert J. Byrne, Carl H. Hobbs Iii

Reports

It i s the objective of this report to supply an assessment, and at least a partial integration, of those important shoreland parameters and characteristics which will aid the planners and the managers of the shorelands in making the best decisions for the utilization of this limited and very valuable resource. The report gives particular attention to the problem of shore erosion and to recommendations concerning the alleviation of the impact of this problem. In addition, we have tried to include in our assessment a discussion of those factors which might significantly limit development of the shoreline and, in some ...


Shore Erosion At Tangier Island, Robert J. Byrne Jan 1976

Shore Erosion At Tangier Island, Robert J. Byrne

Reports

Tangier Island, in Accomack County, Virginia, is the southernmost of a series of islands separating Chesapeake Bay from Tangier and Pocomoke Sounds (Figure 1) . With the exception of three sand ridges, which are the populated areas, the island is low lying marsh and tidal flat deposits with elevations generally below 6 feet (MLW datum).
