Evaluating Geophysical Equipment & Methods

Detailed Description

USGS hydrologists monitor data collection during a geophysical survey using the horizontal-to-vertical ambient-noise seismic method. This method can be used to estimate unconsolidated sediment thickness and map the bedrock surface as part of groundwater investigations. The survey was conducted as part of technology evaluation by the USGS Office of Groundwater Branch of Geophysics in 2007.
