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.

Urban Waters Federal Partnership—Patapsco Watershed (Baltimore, Md. region)

Several watersheds in the Baltimore region have elevated PCB loads in tidal waters. Local jurisdictions are responsible for reducing PCB loading from their watersheds. The USGS is embarking on a pilot study in the Patapsco watershed that will help determine sources of PCBs and will demonstrate innovative monitoring and analysis techniques for more efficient use of mitigation resouces.

Eastern Basins Oil and Gas Assessments

The USGS has conducted several assessments of undiscovered oil and gas in formations in the Blue Ridge Thrust Belt (5068), Piedmont Province (5069), Atlantic Coastal Plain Province (5070), and the New England Province (5072).  These basins are generally east of the Appalachian Basin Province (5067).

Geological Investigations of the Neogene

More than a third of the United States population lives in counties directly on the shoreline, making them vulnerable to hazards associated with changing sea level and storm surges associated with hurricanes and severe storms. The geologic record contains many examples of past intervals of warm climate and high sea level. "Geological Investigation of the Neogene" is examining proxy records of...

Response of a tidal brackish marsh to global change drivers: an ecosystem level manipulation of warming and elevated carbon dioxide- Glenn Guntenspergen

The USGS and the Smithsonian Institution have initiated the first in situ active aboveground and belowground warming experiment in a coastal wetland that is focused on wetland temperature responses and also examines the interaction between warming, elevated CO2, and inundation frequency on wetland resilience in the face of changes in global change drivers.

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...

    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...

    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...
