Advanced Monitoring

The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.

USGS scientists are using high-resolution handheld and airborne thermal imaging cameras in groundwater/surface-water exchange studies and other investigations where surface temperature contrasts indicate various hydrological processes. These cameras are used to quickly locate and characterize thermal (temperature) anomalies along streams, lakes, wetlands, estuaries, and across the landscape...

Fiber-optic distributed temperature sensing (FO-DTS) technology can be used for characterizing estuary-aquifer and stream-aquifer interaction and for identifying transmissive fractures in bedrock boreholes.
