Town Of Colonial Beach Survey Of Central And Castlewood Beaches, Donna A. Milligan, C. Scott Hardaway Jr., Cameron W. Green, Alexander R. Milligan
Town Of Colonial Beach Survey Of Central And Castlewood Beaches, Donna A. Milligan, C. Scott Hardaway Jr., Cameron W. Green, Alexander R. Milligan
Reports
The Town of Colonial Beach occupies a peninsula between the Potomac River and Monroe Bay. Approximately 2.5 miles of the shoreline is publicly-owned. Two areas on the Potomac River have been enhanced as recreational beaches for swimming and sunbathing. Central Beach is located just south of the Town Pier and is the main recreational beach. Castlewood Beach is south of Central Beach near the entrance to Monroe Bay.
Iron Geochemistry Across An Estuary-To-Coastal Gradient, Lissett G. Diaz
Iron Geochemistry Across An Estuary-To-Coastal Gradient, Lissett G. Diaz
Honors Theses
Iron is a ubiquitous earth element that participates in biogeochemical processes that occur in marine sediments. Microorganisms utilize iron for many purposes, including cell growth, conserving energy, and for maintaining metabolic activity. In coastal sedimentary settings, understanding the redox reactions involving ferric iron, Fe3+, and ferrous iron, Fe2+, in its solid phase and pore-water phases, respectively, enable an appreciation of biogeochemical transformations occurring in the coastal zone. In this study, iron concentrations in sediment of ranging permeability were determined at four stations marking an estuary-coast transition zone in Singleton Swash in Myrtle Beach, South Carolina. The …
Plastic Debris In The Laurentian Great Lakes System, North America: Analysis Of Types, Abundances, And Sources, Ian A. Arturo
Plastic Debris In The Laurentian Great Lakes System, North America: Analysis Of Types, Abundances, And Sources, Ian A. Arturo
Electronic Thesis and Dissertation Repository
Understanding plastic pollution in the Laurentian Great Lakes system requires investigation of all plastic debris sizes and categories. Visible polymeric debris (VPD) mainly characterize shorelines, and microplastics (MPs;mm) are found in benthic and beach sediment. Field sampling of VPD from all five Great Lakes, visual and chemical identification of VPD types, and implementation of a matrix scoring technique (MST) indicate that plastic industries, urban areas, and shoreline recreation are major sources of VPD. Sampling for MPs in the St. Clair system, followed by preliminary density separation, and microscopy, suggest that wastewater treatment plants are a major source. This work is …
Dissolved Inorganic Nitrogen Dynamics In Swash Zone Sands Of Long Bay, Sc, Alexis F. Echols
Dissolved Inorganic Nitrogen Dynamics In Swash Zone Sands Of Long Bay, Sc, Alexis F. Echols
Honors Theses
A key component affecting the biogeochemistry of the sedimentary environment is pore water between grains of sediments. Sedimentary microorganisms are constantly modifying chemical compounds as part of their life functions which are then exchanged between the sediment column and the overlying water column. Dissolved inorganic nitrogen, a major element for life, takes on several forms including nitrate, nitrite, and ammonium which vary in concentration throughout the sediment and with respect to each other. The relative concentrations of these nitrogen species have been previously briefly explored in sandy columns, where redox gradients that control their relative concentrations can be fairly deep …
Characterizing Diatom Biofilms And Their Influence On The Sand Biogeochemistry Of High Energy Beaches, Logan C. Jarrell
Characterizing Diatom Biofilms And Their Influence On The Sand Biogeochemistry Of High Energy Beaches, Logan C. Jarrell
Honors Theses
High energy beaches are among the most dynamic ecological settings on Earth. Compared to mudflats, diatoms of high energy beaches have been more neglected in the literature, particularly true of the intertidal biofilms that form and dissipate with nutrient cycling and light intensity over the tidal cycle. Although short lived, the productivity of these biofilms may be critical to the organic-poor sand. Through sediment coring and subsequent analyses of the uppermost sand of three suspected biofilm stations—non-runnel, runnel crest, and runnel trough—along with seemingly bare sand as a control, this study sought to verify the presence of diatom biofilms and …

Town Of Colonial Beach State Of The Beach Data Summary Report, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox
Reports
The Town of Colonial Beach occupies a peninsula between the Potomac River and Monroe Bay (Figure 1). Approximately 2.5 miles of the shoreline is publicly-owned. Two areas on the Potomac River have been enhanced as recreational beaches for swimming and sunbathing. Central Beach extends about 1,650 feet south of the Town Pier and is the main recreational beach. North Central Beach extends about 1,450 feet north of the Town Pier Colonial Avenue. Castlewood Beach is south of Central Beach near the entrance to Monroe Bay. It has about 1,150 feet of sandy beach.

Two areas on the Potomac River have been enhanced as recreational beaches for swimming and sunbathing. Central Beach is located just south of the Town Pier and is the main recreational beach. Castlewood Beach is south of Central Beach near the entrance to Monroe Bay. Mean tide range is 1.64 ft while the spring range 1.94 ft (NOAA,2011).
Specific shore change is addressed at Central Beach and Castlewood Beach through recent beach profiles. Beach profilestaken in January …

State Of Yorktown Beach 2006, Donna A. Milligan, C. Scott Hardaway Jr., Kevin O'Brien, Christine A. Wilcox
Reports
The Yorktown Public Beach is located on the south side of the York River at Yorktown,Virginia (Figure 1). Recently, it has undergone dramatic transformation with the construction of floating piers, upscale restaurants and shops, parking garage, and additional shore management structures. The main recreational beach is now about 1,600 feet in length. A new section of beach and breakwaters is located upstream of the main recreational shore; this project area is 1,500 ft long which includes property owned by the Waterman’s Museum. The middle section of the shoreline downriver of the Route 17 Coleman Bridge, where the floating piers are …
