Geophysical Research and Development (1996-2004)

Many projects within the U.S. Geological Survey use geophysics as a tool for studying buried or concealed geologic features. The availability of modern geophysical instrumentation and data interpretation software is often critical to the success of these projects. However, most projects using geophysics lack the resources to evaluate, purchase, maintain, and provide training for geophysical equipment and software. In addition, the development of any new geophysical technology is a risky, long-term activity, that is well beyond the scope of most individual projects. The Geophysical Research and Development Project provides the geophysical equipment and software tools Geological Survey projects need today, and anticipates and develops new geophysical technologies that the Survey will need within the next five years. Technologies currently supported and under development fall within the general categories of geoelectrical methods, potential-field methods, and gamma-ray methods. These methods permit geophysical investigations at a broad range of scales from national and regional scales to local and site characterization scales, and at a range of depths from a few centimeters to tens of kilometers.
