City Of Hampton, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky

Reports

The data inventory developed for the Shoreline Inventory is based on a three‑tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Hand-held GPS units are used to log features observed in the field.

Three GIS coverages are developed …

Summary Tables: Northampton County, Virginia Shoreline Inventory Report, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt

Reports

The Shoreline Inventory Summary Tables quantify observed conditions based on river systems, such as the combined length of linear features (e.g. shoreline miles surveyed, miles of bulkhead and revetment), the total number of point features (e.g. docks, boathouses, boat ramps) & total acres of polygon features (tidal marshes).

Shoreline Evolution: Surry County, Virginia James River Shorelines, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.

Reports

Surry County is situated on the southern shore of the James River (Figure 1). The County has 168 miles of shoreline along the James River, Upper Chippokes Creek and Grays Creek. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future . Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

The purpose of this report is to document how the shore …

Bi(Otf)3-, Tfoh-, And Tmsotf-Mediated, One-Pot Epoxide Rearrangement, Addition, And Intramolecular Silyl-Modified Sakurai (Isms) Cascade Toward Dihydropyrans: Comparison Of Catalysts And Role Of Bi(Otf)3, R. Frederick Lambert, Robert J. Hinkle, Stephen E. Ammann, Et Al., Robert D. Pike

Arts & Sciences Articles

Catalytic quantities of bismuth(III) triflate efficiently initiate the rearrangement of epoxides to aldehydes, which subsequently react with (Z)-δ-hydroxyalkenylsilanes to afford 2,6-disubstituted 3,6-dihydro-2H-pyrans. Isolated yields of desired products using Bi(OTf)3 were compared with yields obtained when the reactions were run with TfOH and TMSOTf in the presence and absence of several additives. These studies, as well as NMR spectroscopic analyses, indicate an initial Lewis acid/base interaction between Bi(OTf)3 and substrates providing TfOH in situ.

Colonial Beach State Of The Beach Report: 2011, Donna A. Milligan, C. Scott Hardaway Jr., Christine Wilcox

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. 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 …

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2011), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery-dependent and fishery-independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full implementation …

Sea Level Rise: Local Fact Sheet For The Middle Peninsula, Virginia, William G. Reay, Sandra Y. Erdle

Reports

A look at the geologic record of Chesapeake Bay shows a long and dynamic history - from the bolide (asteroid or comet) impact about 35 million years ago which formed the Chesapeake Bay impact crater, to the melting of glaciers beginning about 18,000 years ago, resulting in a continued rise of sea level and drowning of the Susquehanna River valley. Given that the rise in sea level has been occurring for thousands of years and is fundamental to the present formation of the Chesapeake Bay and our local tidal waters, why is there a recent heightened level of concern regarding …

Shoreline Evolution: Richmond County, Virginia Rappahannock River Shorelines, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr.

Reports

Richmond County is situated on the Northern Neck Peninsula in the eastern portion of Virginia (Figure 1). The Rappahannock River forms the southern boundary of this 192 square mile community. The County has 149 miles of shoreline on the Rappahannock River and Cat Point and Totuskey Creeks. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future. Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, …

Virginia Institute Of Marine Science 2011 Greenhouse Gas Inventory Report, Green Team, Virginia Institute Of Marine Science, Justin Birchler, Matt Freedman, Cassie Glaspie, Katie May Laumann, Gar Secrist

Reports

During the spring of 2011, members of the VIMS Green Team, with support from the College of William and Mary’s Committee on Sustainability, collected data on resource use at the VIMS Gloucester Point campus in order to monitor our greenhouse gas emissions and develop methods for reducing our carbon footprint in the future. We processed these data using the Campus Carbon Calculator, a tool developed by Clean Air Cool Planet, a nonprofit organization. This program, used by over 1,200 colleges and universities, calculates the total greenhouse gas emissions of a campus using emissions factors developed by the Intergovernmental Panel on …
