The Horizontal to Vertical Spectral Ratio (HVSR) of broadband seismometer recordings, was explored in this study as a means of characterizing the varying depth to bedrock beneath a glacial drift surface layer. Data were collected using fifteen Guralp CMG-3ESPCD 3-component seismometers deployed from January 15, 2010 to March 16, 2010 over the Stark-Summit gas storage field of Dominion East Ohio. Using Antelope seismic analysis software, I used the HVSR of these seismic data to evaluate the apparent resonance frequency of the glacial drift surface layer and its dependency upon the thickness and shear velocity of the glacial drift. I also constructed a glacial drift thickness contour map in Arcview using bedrock depth information from the Ohio DNR, which was supplemented with additional new bedrock depth data in the area. The bedrock depths vary significantly in the study area but the surface layer resonance appears to be a useful tool to map depth to bedrock.
