Ecosystem Services of Urban Stormwater Management- Kristina Hopkins

As urban development continues to expand, the ecosystem services provided by the urban landscape will be increasingly important to human well-being. Join our interdisciplinary team to help us quantify the water quality services provided by urban stormwater management practices such as rain gardens, infiltration trenches, and detention ponds.

Geomorphic influence on resilience of tidal freshwater wetlands to sea level rise- Greg Noe

Want to conduct collaborative eco-geomorphic research at the forefront of climate change impacts? We have a novel landscape-scale ecosystem experiment, using two adjacent tidal rivers with a 9x difference in watershed sediment loads, to determine how sediment availability regulates the resilience or loss of tidal freshwater wetlands as the result of sea level rise and salinization.

Calcareous Laboratory

In the Calcareous Lab, we use paleoecologic analyses of cores from the eastern U.S. and Gulf Coast to reconstruct past coastal environments and apply that information to current restoration efforts. Most of our current work is focused on South Florida and Everglades restoration.

Piedmont and Blue Ridge Project

The Piedmont and Blue Ridge Project is a geologic mapping project supported by the USGS National Cooperative Geologic Mapping Program. The Piedmont Blue Ridge Project aims to understand the geologic framework and tectonic evolution of terranes and basins in the Appalachian Piedmont and Blue Ridge, and their significance for water, mineral and energy resources, natural hazards, and engineering/...

Coastal Basement Geology of the Southeastern U.S. Project

This project, centered on South Carolina and Georgia, extends coastal-basement geologic mapping and related research south of a geologic map in production for pre-Cretaceous rocks beneath the Atlantic Coastal Plain from Virginia to southern New Jersey, and adds detail to a national-scale basement domain map constructed to delineate mineral-resource...

Functional and Molecular Bioassays

About the Research

The Environmental Health Program collaborates with scientists srom the Functional and Molecular Bioassay Laboratory to apply and modify microbial and eukaryotic reporter bioassays to detect the presence of bioactive chemicals in environmental water samples. These analyses compliment analytical chemistry and biological datasets. The laboratory adapts...

Wetlands in the Quaternary Project

Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi-...

Piedmont Geology Along the Southeastern Fall Zone, Virginia and North Carolina

This task within the USGS NCGMP Piedmont-Blue Ridge Project aims to fill the void in geologic map coverage along the Fall Zone in southeastern Virginia and northeastern North Carolina, and forge strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting DMME and NCGS STATEMAP and UNC–W EDMAP components with targeted geologic mapping and...

Geologic Framework for Seismic Hazards in Central Virginia

The Central Virginia seismic zone (CVSZ) comprises an area of ~13,000 km2 in the central Virginia Piedmont; seismicity in this zone is relatively frequent, but generally mild in magnitude. The August 2011 event was the largest temblor recorded in the CVSZ since the development of modern seismic monitoring and highlighted how little we actually know about the CVSZ, including: 1) the...

    A National-scale River Corridor Model- Jud Harvey

    The need for better models and more effective use of data to characterize river corridor transport processes is keenly felt, from evaluating the effectiveness of river and watershed management practices all the way to clarifying regulatory authority under the Clean Water Act.
