Reports

Derelict fishing gear represents a major challenge to marine resource management: whether through deliberate abandonment or through accidental loss, derelict traps in particular have significant negative effects both economic (e.g., reduced fishery harvest from ghost fishing and gear competition that leads to the reduced efficiency of active gear) and ecological (e.g., degraded habitats and marine food webs and crab and bycatch mortality). Throughout the Chesapeake Bay, commercial harvest of hard-shelled blue crabs is a major fishing activity: every year sees the deployment of several hundred thousand blue crab traps (known locally as crab “pots”) across the Bay, of ...

Werowocomoco Shoreline Management Plan, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox

Reports

Werowocomoco is located on the York River in Gloucester County, Virginia (Figure 1). Historical documents identified Werowocomoco as the headquarters of Powhatan, the Algonquian political and spiritual leader when the English founded Jamestown in 1607. For many years, the exact location of the site was unknown; however, in 2003, archeological digs at the site on the York River between Leigh and Bland Creeks confirmed the location. The site has been occupied by Native Americans since 8,000 before the common era (BCE) and is one of the most important Native American sites in the nation.

In 2016, subsequent to the ...


Shoreline Evolution: City Of Chesapeake, Virginia Elizabeth River Shorelines Data Summary Report, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr. Aug 2016

Shoreline Evolution: City Of Chesapeake, Virginia Elizabeth River Shorelines Data Summary Report, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr.

Reports

City of Chesapeake is situated between the Cities of Norfolk and Portsmouth along several branches of the Elizabeth River (Figure 1). Because the City's shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define where the shoreline will be going in the future. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

The purpose of this ...

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell Apr 2014

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell

Reports

Proliferation of artificial structures to protect shorelines has introduced novel habitat to most coastal environments and fragmented natural habitats. These changes can result in disrupted connectivity, habitat homogenization, and altered estuarine landscapes, with uncertain implications for estuarine and marine faunal community structure and function. In estuaries, such as Chesapeake Bay, where soft-bottom habitat dominates and rocky shorelines are rare, the introduction of artificial rocky structure may enhance recruitment of species that are limited by the availability of suitable substrate including native and introduced species (Bilkovic & Mitchell 2013). There is a significant lack of empirical data on the types of epibiotic ...
