Reports

The City of Virginia Beach is situated along both the Atlantic Ocean and Chesapeake Bay (Figure 1). Through time, the City’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 zone of the City of Virginia Beach has evolved since 1937. Aerial imagery ...

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

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. A combination of handheld GPS units and GPS registered videography were used to collect data on ...


Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2012), Troy D. Tuckey, Mary C. Fabrizio Sep 2012

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2012), 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 ...

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2011 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Karen Hudson Jun 2012

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2011 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Karen Hudson

Reports

The shellfish aquaculture industry in Virginia continues to grow, adding significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. In recent years, folliowing the lead of the hard clam industry, a significant transition to intensive aquaculture of native oysters is underway. The once-extensive oyster planting utilizing wild seed has contracted primarily as a result of endemic oyster diseases and increasing wildlife predation of seed ...

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2011 Annual Report, Eric J. Hilton, Rob Latour, Brian Watkins, Ashleigh Magee Apr 2012

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2011 Annual Report, Eric J. Hilton, Rob Latour, Brian Watkins, Ashleigh Magee

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio ...

Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines : Comprehensive Monitoring Of Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines (Cmls), Phase Ii, Donna Marie Bilkovic, Molly Mitchell

Reports

Armoring shorelines to prevent erosion, improve access, and accommodate individual landscaping interests can result in fragmentation or loss of habitats, reduction in capacity to moderate pollutant loads delivered to coastal waters, reduction in nekton and macrobenthic integrity (Bilkovic et al. 2005, King et al. 2005, Seitz et al. 2006, Bilkovic et al. 2006, Bilkovic & Roggero 2008), increases in invasive species, such as Phragmites australis (Chambers et al. 1999, King et al. 2007), and disturbance of sediment budgets sustaining adjacent properties. As an alternative to traditional armoring of shorelines, shoreline protection techniques incorporating natural elements from the system are increasingly promoted ...
