Cokriging Surface Elevation And Seismic Refraction Data For Bedrock Topography

Analysis of seismic refraction data collected at a proposed site of the Advanced Neutron Source<br>(ANS) Facility showed a strong correlation between surface and bedrock topography. By combining<br>seismically determined bedrock elevation data with surface elevation data using cokriging, we were<br>able to significantly improve our map of bedrock topography without collecting additional seismic data.
