Geophysical System Verification

As digital geophysical sensors were introduced in munitions response projects, the geophysical prove-out (GPO) was developed to determine whether the geophysical data collected would meet project objectives. Over the last 15 years, numerous GPOs have been performed on a variety of site conditions, and a significant body of knowledge has accumulated documenting the performance of these technologies. This accumulated understanding, along with the recognition that magnetic and EM responses of munitions may be predicted reliably using physical models, presents the opportunity for both streamlining and enhancing the GPO with a more rigorous physics-based approach. The Geophysical System Verification (GSV) process retains the essential functions of the GPO while shifting project resources from upfront confirmation of what we already know to ongoing monitoring of project quality.
