Geophysical technologies provide sub-surface imaging capabilities that are used in a variety of field applications. Because geology, target properties, and other site specific factors can vary widely, no single geophysical technology will work well in all areas. In many situations, the use of multiple technologies will yield the best possible target information. The successful application of a geophysical technology occurs when: Objectives are well defined and site conditions are carefully evaluated and used to guide the selection of geophysical technologies, survey design, and survey planning. The interpretation inferred from geophysical geophysical measurements are integrated with geologic, hydrologic, and other available information.
