Collecting Ecological Data and Models of Living Shoreline Restoration Projects

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...

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...

The National Geologic Map Database - NGMDB

The National Geologic Map Database (NGMDB) is a distributed archive of geoscience information for the Nation. It was mandated by the Geologic Mapping Act of 1992 and is cooperatively built and maintained by the USGS and State Geological Surveys. We welcome you to explore the archive, view the maps, and help us to...

Heavy-Mineral Sand Resources in the Southeastern U.S.

We are assessing the extent of industrial mineral resources hosted by heavy-mineral sands in the coastal plain of the southeastern United States. “Heavy-mineral sands" (HMS) is a term commonly used in industry and geologic literature to describe layered sediments deposited in coastal environments that contain dense (“heavy") minerals of economic value. The heavy minerals extracted from these...

Monitoring the Shenandoah salamander in Shenandoah National Park

The Shenandoah salamander (Plethodon shenandoah) is a federally endangered species found only within the boundaries of Shenandoah National Park, Virginia.  This terrestrial salamander is isolated to approximately 6 km² of dry talus slopes at high elevations in the park.  Results of previous research suggest that P. shenandoah is competitively excluded to suboptimal talus...

U.S. Geological Survey (USGS) Science Summary—The Role of Storms on Bank Erosion Rates and Sediment Transport in Urban Areas

Sediment is a major pollutant degrading aquatic ecosystems in the Chesapeake Bay watershed. The USGS is conducting studies to determine the relative importance of streambank erosion to other sediment sources, such as upland erosion, in both agricultural and urban areas. The information is necessary so resource managers can focus on the types, and locations, of practices that will be most...
