FRESC Snake River Field Station

The scientists of the Snake River Field Station (SRFS) work throughout the western United States, particularly in the public lands of the Intermountain West, Great Basin, and Columbia Plateau. Their work addresses wildlife monitoring protocols; sage-grouse distribution, population trends, and habitat associations; rangeland ecology and restoration; invasive-species management; fire ecology;...

Interagency Grizzly Bear Study Team

The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy...

Macroinvertebrate Communities Evaluated Before and After a Channel Restoration Project in Silver Creek, Blaine County

The U.S. Geological Survey, in cooperation with Blaine County and The Nature Conservancy, evaluated the status of macroinvertebrate1 communities prior to and following a channel restoration project in Silver Creek, Blaine County, Idaho. The objective of the evaluation was to determine whether 2014 remediation efforts to restore natural channel conditions in an impounded area of Silver Creek...

Quantitative Disease Ecology

Researchers at the USGS are working on developing new quantitative methods to study disease dynamics in wildlife systems as well as systems at the wildlife-domestic-human interface. Much of our work focuses on how host population structure affects disease invasion, persistence and control in wildlife disease systems. We tackle these issues with a combination of simulation and statistical...

Groundwater Flow Modeling - Idaho National Laboratory

Numerical models are being used to better understand the flow of groundwater and the transport of radiochemical and chemical constituents in the eastern Snake River Plain aquifer system.

The models, developed at the INL, afford scientists a framework to organize their knowledge and concepts of groundwater systems and to provide insights for water-resource managers for future water...

Geochemical Modeling - Idaho National Laboratory

Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.

Developing Geological Framework - Idaho National Laboratory

As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.

Drilling and Coring - Idaho National Laboratory

We drill and maintain wells around the INL to monitor and sample groundwater, obtain basalt and sediment cores for study and analysis, and study the physical properties of the subsurface (geophysical logging).

This information helps us to improve the scientific understanding of the eastern Snake River Plain and its aquifer. In particular, we are examining the subsidence of the plain and...

Video Logging - Idaho National Laboratory

Drillers use the vertical and horizontal views captured by our downhole video camera to examine borehole integrity before placing water well casing, well screens, and submersible pumps. Hydrologists and geologists use the images to verify geophysical data such as: changes in rock type, small-scale geologic structures, rock fractures, and groundwater movement.
