Transient Electromagnetics, Passive Seismic, and Borehole Electromagnetics, Gamma, and Nuclear Magnetic Resonance Methods to Characterize Glacial Sediments in East Falmouth, Massachusetts, Near Nantucket Sound
Passive seismic horizontal-to-vertical spectral ratio (HVSR) methods were used to estimate the depth of the unconsolidated deposits over bedrock.  The HVSR method  uses a three-component seismometer to measure the vertical and two horizontal components of ambient seismic noise. Seismic noise in the range of ~0.1 to 1 …
