Status Of The Major Oyster Diseases In Virginia 2006-2008 A Summary Of The Annual Oyster Disease Monitoring Program, Ryan Carnegie, Eugene M. Burreson

Reports

Fall Survey sampling revealed P. marinus levels to be generally normal to high in Virginia tributaries. By 2007 P. marinus was present on every oyster reef sampled, and by the end of the 2006-2008 period the parasite was probably causing some mortality throughout Virginia waters. Data for H. nelsoni are still incomplete for 2006/7 because of funding limitations, but in 2008 H. nelsoni was observed at 17 of 31 sampled reefs, a marked expansion in distribution since 2003/4. A significant MSX disease outbreak occurred in the Great Wicomico River in 2008, as a mild winter and a long period of …

Estimating Relative Abundance Of Young-Of-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2009), 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 …

Tidal Sediment Yield Estimate Methodology In Virginia For The Chesapeake Bay Program Water Quality Model, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Julie Herman

Reports

Water quality in Chesapeake Bay has degraded over the past 50 years with respect to oxygen depletion and reduced light attenuation. While the causes are numerous, sediment resuspension from wave and tidal action cloud the water column and reduce light attenuation thereby negatively affecting submerged aquatic vegetation (SAV) beds. Sediments on the Bay bottom come from upland runoff and shoreline erosion, each of which has significant contributions to the loading of sediments into estuary. The purpose of this report is to assess the present methods used to calculate sediment loading from tidal shoreline erosion that is input to the Chesapeake …

Shore Status, Evolution, And Storm Vulnerability Assessments For George Washington Birthplace National Monument, C. Scott Hardaway Jr., Donna A. Milligan, Kevin P. O'Brien, Christine A. Wilcox

Reports

The shoreline at the George Washington Birthplace National Monument (GEWA) is eroding and vulnerable to storms. Recent storms, such as Hurricane Isabel and Tropical Storm Ernesto impacted the region in 2003 and 2006, respectively. Large losses of the bank prompted the National Park Service to determine the vulnerability of the shore and its associated cultural, natural and archeological resources. This project maps the existing shoreline along the Potomac River and at the Memorial House on Popes Creek, provides an assessment of shore and bank dynamics, determines the rate of shoreline change between 1937 and 2007, and presents an analysis of …

Encroachment Of Sills Onto State-Owned Bottom: Design Guidelines For Chesapeake Bay, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine A. Wilcox, Jian Shen, Carl H. Hobbs Iii

Reports

Recent efforts have sought to expand the use of “Living Shorelines” by waterfront property owners in Virginia and Maryland to combat tidal shoreline erosion. Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. Some regulatory agencies and non-governmental organizations prefer living shorelines over “traditional” shore hardening using bulkheads or stone revetments because these structures create a “barrier” or disconnect between the upland and marine environments. Typically, creation of a living shoreline involves the placement of sand, planting marsh flora, and, if necessary, …

Climate Change Impacts In Virginia: Status Of Natural Resource Data Records As Tools To Assess Continuing Trends, Tamia Rudnicky, Marcia Berman, Roger L. Mann, Carl Hershner

Reports

As scientists we pose the hypothesis that climate change over the past decades has left a signal in natural resource status and productivity in Virginia. This signal exists subsumed in a variety of data from crop and forestry production, to fishery landings, to spatial distribution of numerous plant and animal species of interest. Description of these signals in concert with known changes in climate descriptors (temperature, rainfall and more) provide a basis for hind-casting possible cause and effect relationships. If such relationships exist, and we hypothesize that they do, then projections of climate descriptors (temperature, rainfall and more) provide the …

Dune Monitoring Data Update Summary, Kevin P. O'Brien, Donna A. Milligan, George R. Thomas

Reports

The Shoreline Studies Program at VIMS established a beach and dune monitoring program for nine sites around the Virginia portion of Chesapeake Bay (Milligan et al., 2005). These sites were monitored twice yearly for four years (2001-2004). In addition to three years of relatively calm conditions, these data included the impact of Hurricane Isabel, a nearly 100-yr event, on the Bay’s shorelines. The shoreline’s change due to the storm and their subsequent short-term recovery was documented by this data. However, since the end of the monitoring program, other events have impacted Chesapeake Bay shorelines. In order to document the longer-term …

Vulnerability Of Shallow Tidal Water Habitats In Virginia To Climate Change, Donna Marie Bilkovic, Carl H. Herschner, Tamia Rudnicky, Karinna Nunez, Daniel E. Schatt, Sharon Kileen, Marcia Berman, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

The principal objective of this study was to develop a characterization of current shallow-water habitat components in Virginia tidal waters and predict climate driven changes to these habitats. To project broad-scale climate change effects on the abundance and distribution of coastal habitats, an inundation model based on anticipated relative sea-level rise, temperature and salinity projections, and coastal development were integrated into a GIS modeling framework. Using this framework, simple models were constructed that forecast the distribution of key coastal habitat parameters within the next 50 to 100 years including: shallow-water areas, tidal wetlands, submerged aquatic vegetation and estuarine beaches. The …

Extreme Storm Events Increase The Risk For Chemical Contamination Of Coastal Waters, Michael A. Unger, Virginia Institute Of Marine Science. Initiative For Coastal Climate Change Research

Reports

Sea-level rise and an increase in the severity of coastal storms are probable outcomes for the Chesapeake Bay due to global climate change. A consequent ecological and economic risk for tidewater Virginia and other low-lying coastal zones is the contamination of coastal waters by industrial and agricultural chemicals released by accidental spills during severe storm events. . . .

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

This study classified tidal wetlands for the Lynnhaven Watershed using remote sensing techniques and high resolution imagery from 2007. This updated delineation of wetlands, was used in conjunction with a simplistic geospatial elevation model to quantify the potential loss of wetlands under various sea level rise scenarios.The study revealed that using conservative estimates of sea level rise, nearly all wetlands would be lost by the year 2100. Projecting sea level rise into the future can be considered speculative, nevertheless such predictions are necessary to begin managing for and planning for climate change impacts. Evidence from this study suggests that upland …
