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/...
Bird Banding Laboratory
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Tidal Freshwater Ecosystems
This habitat system is characterized as tidally influenced freshwater systems, which provide critical habitat for many migratory (diadromous) fish species. Characteristic species that inhabit this zone include mussels, sturgeon, shad, herring, alewife, American eel, striped bass, and perch.
Freshwater Mussel Physiology
Freshwater mussels are considered ecosystems engineers benefiting the streams and rivers they inhabit through filtration, biodeposition, and nutrient cycling, thereby influencing water quality. However, many of these species are rapidly declining due to shifting environmental conditions and habitat loss. Researchers at Leetown Science Center are evaluating how different species of mussels...
Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed
Floodplain and wetland areas provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. The loss of floodplain functionality due to land use conversion and degradation reduces the provisioning of these services. Assessing, quantifying, and valuing floodplain ecosystem services provide a framework to estimate how floodplain...
National Assessment of Coastal Vulnerability to Sea Level Rise
This research seeks to objectively determine the relative risks due to future sea-level rise for the U.S. Atlantic, Pacific, and Gulf of Mexico coasts. Research is part of National Assessment of Coastal Change Hazards project.
Long-Term Coastal Change
Goals of this project include developing and improving coastal-change assessments and supporting long-term planning and decision making to ensure sustainable coastal economies, infrastructure, and ecosystems. Research is part of the National Assessment of Coastal Change Hazards...
National Assessment of Coastal Change Hazards
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
