Chart Comparing 57 Geophysical Methods With 17 Applications and Disciplines

Chart of who is using geophysical methods and for what

This chart is based on over thirty years of experience in conducting near surface geophysical surveys. The list is compiled from common uses for geophysical methods and is cross referenced with a list of geophysical equipment. Geophysical instruments that are considered less common are not listed. Without doubt, almost all the geophysical methods may be applied to many other disciplines that are not listed. Note: this chart is based on manufactures statements, experience, and opinions. There are no guarantees and no replacement for experience. This list of geophysical equipment may or may not yield desirable results. Without doubt, there are other instruments and unique configurations available for deeper exploration, see the home page for more options.
