Generating a Statistically Constrained Quaternary Model of a Buried Bedrock Valley Using FDEM. [PDF]

Ground Water
Abstract An airborne electromagnetic (AEM) survey was conducted using the Resolve™ frequency‐domain system over a buried bedrock valley near Elora, Ontario, Canada. A statistical bootstrapping approach was used to establish a relationship between the electrical resistivity from spatially interpolated one‐dimensional AEM resistivity models and the ...
