Unified Interior Regions
Maryland
Maryland's water supply comes from streams, rivers, groundwater and reservoirs. Many of these systems flow to the Chesapeake Bay, the Nation's largest estuary. This complex ecosystem has been degraded due to the impact of human-population increase. The MD-DC-DE Water Science Center studies the impacts this has on water quality, habitats and biological communities.

Understanding the Effects of Stormwater Management Practices on Water Quality and Flow
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...

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...
Appalachian Basin Oil and Gas Assessments
The USGS has conducted numerous assessments of undiscovered oil and gas in the Appalachian Basin, including studies of the Marcellus Shale. The region extends from Alabama to Maine. The following is an overview of the assessments.

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...
Flow Modeling at Dam Removal Sites Associated with Hurricane Sandy Resiliency Efforts
The purpose of this work is to better understand the effects of dam removal on local hydraulics, fish passage, and flooding. This study is part of a larger effort to monitor ecological resilience changes at nine Hurricane Sandy coastal resiliency aquatic connectivity restoration projects. It will contribute crucial knowledge that will be used to improve aquatic connectivity system cost-...
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...
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...

Disease Resistance of Wildlife Species: how the immune system evolves and adapts
The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens. Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species. The vertebrate immune system is not static. Rather, it involves in response to the environment.
Coastal and Marine Geology Video and Photography Portal
This portal contains U.S. Geological Survey (USGS) video and photography of the seafloor off of coastal California and Massachusetts, and aerial imagery of the coastline along segments of the Gulf of Mexico and mid-Atlantic coasts. These data were collected as part of several USGS Coastal and Marine Geology Program Seafloor Mapping projects and Hurricane and Extreme Storm research.
Orthoimagery Data
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map Small-Scale Collection
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
High-resolution geophysical data collected along the Delmarva Peninsula in 2015, U.S. Geological Survey Field Activity 2015-001-FA
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework
Geochemical analysis of authigenic carbonates and chemosynthetic mussels at Atlantic Margin seeps (ver. 2.0, March 2019)
Isotopic analyses of authigenic carbonates and methanotrophic deep-sea mussels, Bathymodiolus sp., was performed on samples collected from seep fields in the Baltimore and Norfolk Canyons on the north Atlantic margin. Samples were collected using remotely operated underwater vehicles (ROVs) during three different research cruises in 2012, 2013, and 2015. Analyses were performed by sev
