Public Beach Assessment Report Gloucester Point Public Beach, Gloucester County, Virginia, Donna A. Milligan, C. Scott Hardaway Jr., George R. Thomas Nov 1996

Public Beach Assessment Report Gloucester Point Public Beach, Gloucester County, Virginia, Donna A. Milligan, C. Scott Hardaway Jr., George R. Thomas

Reports

Gloucester Point Public Beach is located at the southern end of Gloucester County, Virginia on the York River. It is a southeastward facing shoreline about 960 ft long and it is part of a larger stretch of moderately low shore between Sarah Creek and the George P. Coleman Bridge. While no shoreline improvement projects have taken place at the public beach, shore protection projects updrift and including the Virginia Institute of Marine Science (VIMS) affect it. In 1983, erosion along the shoreline at VIMS just updrift of the public beach led to the installation of a riprap revetment in front ...

Investigations Of Isolated Sand Shoals And Associated Deposits, Virginia Inner Shelf : Final Contract Report Primarily In The Form Of A Data Report, C. H. Hobbs Iii Jan 1996

Investigations Of Isolated Sand Shoals And Associated Deposits, Virginia Inner Shelf : Final Contract Report Primarily In The Form Of A Data Report, C. H. Hobbs Iii

Reports

This report primarily serves to present minimally interpreted data from a tight spaced set of high-resolution, seismic-reflection, sub-bottom profiles obtained during the summer of 1992. The profiles were run in the inner continental shelf adjacent to Virginia Beach, Virginia as part of an investigation of offshore sounds potentially usable in beach nourishment and hurricane protection projects along Virginia's Atlantic shore south of the mouth of Chesapeake Bay. Figure 1 depicts the general study area.

Berquist and Gomillion (1993) presented an interpretation of a small portion of the work. A larger, interpretive report (Hardaway et al., 1995) also utilizes information ...


Hydrodynamics Of Sediment Suspensions In The Littoral Zone Of The Lower York River - Phase I, John D. Boon Jan 1996

Hydrodynamics Of Sediment Suspensions In The Littoral Zone Of The Lower York River - Phase I, John D. Boon

Reports

Motivation for this study derives from a need to know more about processes governing sediment suspension within the shallow waters of the littoral zone (depths< 2m) in coastal estuaries. These are regions in which bottom sediment, in the absence of vegetative cover and depending on grain sizes present, has the potential to be actively eroded and entrained in the water column by wind waves and/or currents. Suspended sediment has the further potential to impact water quality and promote eutrophication through nutrient enrichment processes (Kemp et al., 1983; Orth and Moore, 1983). High sediment loadings also lead to light reduction in the photic zone which can impact the growth or survival of submerged aquatic vegetation (De Groot and de Jonge, 1990).


Lipid Biomarker Composition Of Particulate Organic Matter In The Lower Chesapeake Bay : A Final Data Report, Elizabeth Canuel, Andrew Zimmerman, Shannon Burcham Jan 1996

Lipid Biomarker Composition Of Particulate Organic Matter In The Lower Chesapeake Bay : A Final Data Report, Elizabeth Canuel, Andrew Zimmerman, Shannon Burcham

Reports

In this report we present results from a sampling program designed to characterize the abundance, sources, and composition of particulate organic matter (POM) in the lower Chesapeake Bay. To meet these objectives, we used measurements of bulk parameters (total suspended solids, chlorophylls, particulate carbon and nitrogen concentrations) combined with information on the concentration of two classes of lipid biomarker compounds (fatty acids and sterols). In addition to providing baseline information on the sources and composition of POM important to the lower Bay, the study addressed spatial and temporal variations in organic matter quality. This was accomplished using an experimental design ...

Effects Of Sand-Mining On Benthic Communities And Resource Value : Thimble Shoal, Lower Chesapeake Bay, Linda C. Schaffner, Michele A. Horvath, Carl H. Hobbs Iii Jan 1996

Effects Of Sand-Mining On Benthic Communities And Resource Value : Thimble Shoal, Lower Chesapeake Bay, Linda C. Schaffner, Michele A. Horvath, Carl H. Hobbs Iii

Reports

In August 1990 the City of Hampton placed approximately 276,000 cubic yards of sand from a designated borrow site on Thimble Shoal onto Buck:roe Beach for beach restoration. The Buck:roe reserve identified by Kimball et al. (1989) contains large quantities of beach quality material and is located less then 2.5 km offshore of Buck:roe Beach. In early 1989 a small section (330 m by 240 m) located in 5 m of water was delineated and permitted for dredging. This project represents the first instance of permitted, sand-mining activities for beach nourishment in the lower bay ...

Virginia Game Fish Tagging Program Annual Report 1995, Cm Bain Iii, John A. Lucy

Reports

The Virginia Came Fish tagging Program (VGFTP) was established in 1995 as an ongoing, cooperative project of the Virginia Marine Resources Commission and the Virginia Institute of Marine Science of the College of William and Mary The project is funded with revenues generated by Virginia's marine recreational fishing license.


Hydrodynamics Of Sediment Suspensions In The Littoral Zone Of The Lower York River - Phase Ii, John D. Boon Jan 1996

Hydrodynamics Of Sediment Suspensions In The Littoral Zone Of The Lower York River - Phase Ii, John D. Boon

Reports

This report covers the second year (Phase II) of a two-year study. An earlier contract report (Boon,1996) was submitted in January, 1996, to the Virginia Coastal Resources Management Program covering the first year (Phase I) results of a wave , current and suspended sediment monitoring study conducted at the mouth of the York River (Figure 1).

The purpose of the monitoring study , as originally planned , was to investigate processes governing sediment suspension within the shallow waters of the littoral zone (depths< 2m) in coastal estuaries. These are regions in which bottom sediment, in the absence of vegetative cover and depending on sediment grain sizes present, has the potential to be actively eroded and entrained in the water column by wind waves and/or currents. Suspended sediment has the further potential to impact water quality and promote eutrophication through nutrient enrichment processes (Kemp et al., 1983; Orth and Moore, 1983). High sediment loadings also lead to light reduction in the photic zone which can impact the growth or survival of submerged aquatic vegetation (De Groot and de Jonge, 1990) .


Analysis Of Temporal And Spatial Variations In Vegetation Communities For The Buxton Woods Region Of Cape Hatteras National Seashore, Marcia Berman, Gene Silberhorn, Carl Hershner Jan 1996

Analysis Of Temporal And Spatial Variations In Vegetation Communities For The Buxton Woods Region Of Cape Hatteras National Seashore, Marcia Berman, Gene Silberhorn, Carl Hershner

Reports

Residential development and growth along private lands bordering the southern portion of Cape Hatteras may be increasing at a rate inconsistent with the current water supply and demand. In the late 1960's and again in the late 1970's a series of wells were drilled to supply area residences and businesses with potable water from the local shallow water aquifer. Today, additional wells are being considered to serve the expanding community of Buxton Woods.

At the same time, the National Park Service maintains a series of ditches for both mosquito and flood control management. A large ditch which trends ...
