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

  • Geochemistry of Hydrothermal Systems

    Geochemistry of Hydrothermal Systems: Bill Evans demonstrates proper use of a ring stand and graduated cylinder to collect gas from an Alaskan mud volcano. This feature was dormant for decades before "erupting" carbon dioxide gas in the late 1990s.

  • 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.

  • Stable Isotope Fractionation in Hydrologic Processes

    Stable Isotope Fractionation in Hydrologic Processes : T. B. Coplen prepares gas samples on a glass high vacuum line in the Reston Stable Isotope Laboratory. In this laboratory, samples are analyzed for hydrogen, carbon, nitrogen, oxygen, and sulfur isotopic composition for biological, hydrological, environmental, and forensic science applications.

  • Environmental Tracers of Surface-Water/Ground-Water Exchanges

    Environmental Tracers of Surface-Water/Ground-Water Exchanges: James Constantz is the leading authority on the use of heat as a tracer to understand and quantify surface-water exchanges with groundwater, as well as a leading authority regarding the influence of temperature on hydrologic processes, including infiltration, evaporation and drainage.

  • Ecohydrology of Arid Lands

    Ecohydrology of Arid Lands: Julio Betancourt studies how climate variability affects terrestrial ecosystems. Here Julio is sampling and analyzing fossil rodent middens preserved in caves and rock shelters along remote cliffsides to reconstruct vegetation dynamics over the past 50,000 years in arid North and South America.

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.
