Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle
Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle
Reports
This study describes the most extensive effort to characterize the chemistry, toxicology and community of the sediments of the Mattaponi and Pamunkey Rivers. This was accomplished using a study design modified to expand the number of stations occupied by reducing the cost of analyses by compositing replicate samples collected from each study site rather than performing toxicity tests on these samples individually. In previous studies, the variability in field replicate samples was equivalent to the variability in laboratory replicates. This design has long been used to analyze samples for various chemical contaminants as a cost savings endeavor. More ....
The Value Of Created Dunes To Address Coastal Hazards In Chesapeake Bay: Hurricane Isabel Impacts, C. Scott Hardaway Jr., Donna A. Milligan, Travis R. Comer
The Value Of Created Dunes To Address Coastal Hazards In Chesapeake Bay: Hurricane Isabel Impacts, C. Scott Hardaway Jr., Donna A. Milligan, Travis R. Comer
Reports
Perhaps the most important function of a created dune, from some perspectives, is coastal protection. Since the initiation of this subtask within the overall Chesapeake Bay Dune Monitoring and Management Analysis project, Hurricane Isabel impacted the coastal plain of Virginia and significantly altered almost all Bay shorelines to one degree or another. This is particularly true of shorelines facing north, east, and south since the winds shifted as the storm passed. The original task scope has changed slightly as a result of Isabel’s passage since it was such a significant storm event and provided an opportunity to show how dunes …

Accomack County Dune Inventory, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, George R. Thomas, Walter L. Priest, Linda M. Meneghini, Thomas A. Barnard, Christine A. Wilcox
Reports
Accomack County is located on the Eastern Shore of Virginia (Figure 1). Only dune sites on Chesapeake Bay were analyzed. A total of 33 dune sites were identified along Accomack’s shoreline (Figure 2). It is the intent of this publication to provide the user with information on the status of dunes in Accomack County. This information comes from research performed in 1999 and 2000 which was presented in a report entitled “Chesapeake Bay Dune Systems: Evolution and Status (Hardaway et al., 2001). Although somewhat dated, the information provides a short historical perspective of the state of each site at the …
