Geophysical Methods
The geophysical methods section of the website presents a more comprehensive discussion of the geophysical methods and theory. This section is divided into two broad categories, surface methods, and borehole methods. To develop a complete understanding of the theory and science of geophysical methods requires an understanding of the geophysical properties involved in the methodology.
