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.

  • Plankton Dynamics in Tidal Estuaries

    Plankton Dynamics in Tidal Estuaries: Jim Cloern gives a tutorial on scientific writing and publishing for graduate students at the National Institute of Oceanography, Goa, India.

  • Benthic Fluxes of Metals and Nutrients

    Benthic Fluxes of Metals and Nutrients: Jim Kuwabara and his colleagues use a USGS-patented device to quantify changes in the benthic (internal) sources of nutrients and toxic substances to various aquatic systems. This research supports the development of long-term management strategies for water quality in these ecosystems.

  • 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.

  • Stable Isotope Tracing of Metals in Aquatic Ecosystems

    Stable Isotope Tracing of Metals in Aquatic Ecosystems: Marie Croteau studies the linkages between contaminant bioavailability and toxicity in aquatic organisms exposed to metals, including colloidal metals and engineered nanoparticles. This is a SEM image of benthic diatoms (Nitzschia palea) and zinc oxide nanoparticles.

Topical Research Teams

The National Research Program's topical research teams consist of small groups of scientists that cross the boundaries of historic USGS sub-disciplines, Branches, and Mission Areas. They often include scientists from outside agencies as well. These teams are formed to address potentially important issues for which there currently is limited activity in the Water Mission Area. Outcomes from the topical teams could identify new research directions and result in the formation of new collaborations and partnerships.

The Fate of Sediment When Freshwater Meets Saltwater

Tidal freshwater swamp along the Pocomoke River in Maryland.

Two recent USGS investigations, have measured sedimentation rates along the barely perceptible slope of rivers as they empty into estuaries. The findings of these studies have important implications for the restoration of estuaries - for example, the Chesapeake Bay - and their resilience in the face of sea level rise.

Marjorie Schulz: Soil Mottling Not in Wetlands Only

View of mottled pattern characteristic of rhizospheric processes.

USGS scientists led by Marjorie Schulz have shown that rhizospheric processes, acting over tens of thousands of years under upland prairie coastal terraces, orchestrate the redistribution of elements into distinct mottled patterns, with implications for pedogenesis, weathering of plant-essential nutrients, and carbon sequestration in deep soils.
