The USGS National Research Program (NRP), part of the USGS Water Mission Area, conducts research to develop and disseminate science-based information and tools needed for a fundamental understanding of the processes that affect the availability, movement, and quality of the Nation’s water resources. Our science supports a wide range of policies and activities, including:

Science Topics

  • Biogeochemical Controls on Contaminant Degradation in Heterogeneous Near Surface Environments

    Biogeochemical Controls on Contaminant Degradation in Heterogeneous Near Surface Environments: Isabelle Cozzarelli's research is to investigate the impact of organic contaminants in aquifers and wetlands, requiring her and her colleagues to use field-based experimental approaches to look at reactions below land surface.

  • Hydrogeology of Lakes, Wetlands and Streams

    Hydrogeology of Lakes, Wetlands and Streams: Don Rosenberry investigates the spatial and temporal variability of exchange between groundwater and surface water in response to changes in the geometry and hydrogeologic properties of this interface that are driven by episodic and sustained fluvial and hydrologic events.

  • Biogeochemical Controls on Contaminant Degradation in Heterogeneous Near Surface Environments

    Biogeochemical Controls on Contaminant Degradation in Heterogeneous Near Surface Environments: Denise Akob uses microbiology, molecular biology, and biogeochemistry to understand the role of microorganisms in both contaminated and pristine ecosystems.

  • Hydroecology of Flowing Waters

    Hydroecology of Flowing Waters: Jud Harvey is shown sampling the Six-Mile Brook streambed for mercury contamination in Adirondack State Park, New York.

  • Mechanisms of Biological and Ecological Response in Disturbed Aquatic Ecosystems

    Mechanisms of Biological and Ecological Response in Disturbed Aquatic Ecosystems: Janet Thompson with a USGS field crew sampling the animal community in and under the aquatic vegetation of the San Francisco Estuary.

Arctic Methane Emissions "Certain to Trigger Warming"

Coastal erosion reveals permafrost underlying the Arctic Coastal Plain in Alaska.

As climate change melts Arctic permafrost and releases large amounts of methane into the atmosphere, it is creating a feedback loop that is "certain to trigger additional warming," according to the lead scientist of a new study investigating Arctic methane emissions.

The Connected Consequences of River Dams

Conceptual model of how two dams in a sequence may interact.

In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.
