Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick
Reports
Shoreline habitats and processes are impacted by the decisions we make about managing coastal development and shorelines. Shoreline Management is making choices to address the desire to protect upland property from erosion or develop property balanced with the benefits and uses of natural and nature-based shoreline features and shoreline habitat restoration. This requires a weighing of the private benefits and cots of management actions and the benefits and costs to public held common resources, also known as the public trust. The natural features along our shorelines -tidal wetlands, beaches and dunes, and riparian buffers, are economically and ecologically valuable. They …

Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge, Richard A. Snyder, Paige G. Ross
Reports
Previous sampling of the stream crossing Bobtown Road (Rt 178) near the intersection of Hollies Church Road (Rt. 620), had indicated high levels of nitrogen in the stream flow (Snyder and Ross, 2019a). The proximity of the retired Accomack County Landfill upstream of the site triggered a higher resolution sampling of the stream in an attempt to isolate a source of the nitrogen loading (Snyder and Ross, 2019b). Accomack County has requested repeated sampling of this stream segment to monitor nutrient attenuation trends from the site, and stations were established for that purpose. This is the first report of that …

2019 Chesapeake Bay Dead Zone Report, Virginia Institute Of Marine Science, Anchor Qea
Reports
The “Dead Zone” of the Chesapeake Bay refers to a volume of bottom water that is characterized by dissolved oxygen concentrations less than 2 mg/L, which is too low for aquatic organisms such as fish and blue crabs to thrive. The Chesapeake Bay experiences such “hypoxic”conditions every year, with the severity varying from year to year, depending on nutrient and freshwater inputs, wind, and temperature. Multiple metrics are used to relate the severity of hypoxia between different years:
- Maximum Daily Hypoxic Volume (km3): The maximum volume of Chesapeake Bay water experiencing hypoxic conditions on any given day
- Average Summer Hypoxic …

Impacts Of Sea Level Rise On Hypoxia In The Chesapeake Bay: A Model Intercomparison, Pierre St-Laurent, Marjorie A.M. Friedrichs, Ming Li, Wenfei Ni
Reports
Over recent years a number of studies have examined the effects of sea level rise (SLR) on hypoxia in Chesapeake Bay. However, variations in the methodology, the years considered, and the metrics reported made comparisons between these studies difficult. To clarify the effects of SLR on the Bay’s hypoxia, we present an intercomparison between four numerical models following a common methodology. The models share the riverine fluxes, baseline period (1991–1995), and consider the same three scenarios of SLR: an increase in sea level of 0.17m, 0.50m, and 1.00m (representative of years 2025, 2050 and 2100, respectively). SLR is the sole …
