Spectral Gamma Borehole Logging

Spectral gamma borehole geophysical methods measure natural-gamma energy spectra, which are caused by the decay of uranium, thorium, potassium-40, and anthropogenic radioactive isotopes. Spectral gamma data can be used to identify and quantify the amount of uranium, thorium, and potassium-40 isotopes detected in boreholes.

Water Chemistry Data for Selected Springs, Geysers, and Streams in Yellowstone National Park, Wyoming, Beginning 2009

Results of water analyses conducted on numerous thermal and non-thermal features in Yellowstone National Park beginning in 2009. Water samples were collected and analyzed as part of research investigations on arsenic, iron, nitrogen, and sulfur redox species in hot springs and overflow drainages; the occurrence and distribution of dissolved mercury; and general hydrogeochemistry of hot springs...

Thermal Imaging Camera Use: Identifying Groundwater Inputs to a Reef in American Samoa

USGS scientists used a thermal camera in American Samoa to understand the effect of land-based contaminants on an adjacent coral reef lagoon ecosystem. The infrared (IR) camera was used to capture thermal images of the lagoon to look for temperature differences to understand the distribution of freshwater entering the lagoon and the circulation of the lagoon water at various tidal levels.

What does groundwater have to do with ice in Alaska?

USGS scientists are working alongside university researchers in Alaska to understand how groundwater and permafrost conditions change over time due to seasonal variations and climate change. Changes in permafrost can pose a threat to built infrastructure (like roads, homes, and pipelines) and to valued ecological resources that provide important habitats for wildlife.

Geophysics for USGS Groundwater/Surface Water Interaction Studies

Understanding the interaction of groundwater and surface water is essential to water managers and hydrologists for the development of effective water-resource policy, protection, and management. The USGS conducts applied research to evaluate the use of new or emerging hydrogeophysical tools and methods to improve our understanding of groundwater/surface-water exchange.

Handheld Thermal Imaging Cameras for Groundwater/Surface-Water Interaction Studies

USGS scientists are using high-resolution handheld thermal imaging cameras in groundwater/surface-water interaction studies and other investigations. These cameras are used to quickly locate and characterize thermal anomalies in streams, lakes, and adjacent structures. Variations in temperature can be used to track the heat carried by flowing water, such groundwater discharge into a stream....

Integration of sUAS into Hydrogeophysical Studies: Technology Demonstration and Evaluation

The USGS is evaluating the integration of small unoccupied aircraft systems – sUAS or "drones" –  into USGS hydrogeophysical studies. The following projects are part of a Wtaer Resources Mission Area demonstration and evaluation effort in collaboration with USGS Water Science Centers (WSCs) starting in June 2018.

Hydrologic and Erosion Responses of Burned Watersheds

The enhanced probability of catastrophic wildfires has increased our need to understand the risk of floods, erosion, and debris and contaminant transport in burned watersheds. This project investigates the relation between rainfall intensity and peak discharge; erosion and deposition processes; and water-quality impacts to minimize the loss of life and property resulting from post-wildfire...
