Geophysics (Subsurface Remote Sensing)

Geophysical applications in archaeology consist of a suite of tools designed to measure the physical properties of the earth and distinguish them from buried components of the archaeological record. Statistical Research, Inc., routinely employs a variety of instruments, including ground-penetrating radar, magnetic gradiometry, and electrical resistivity, in order to create a virtual window into shallow subsurface deposits. Other subsurface remote-sensing techniques include electromagnetic conductivity, magnetic susceptibility, and resistivity sounding. These inexpensive and noninvasive techniques have a clear advantage in preserving and managing archaeological resources and are part of SRI’s larger program of cultural heritage preservation, protection, and management. Statistical Research, Inc., has conducted over 20 geophysical projects throughout the southwestern and western United States since 1995. Government clients have included the Arizona Department of Transportation (ADOT), the Bureau of Land Management (BLM), the Bureau of Reclamation (BOR), various United States Army Corps of Engineers (USACE) districts, the City of Albuquerque, and the Arizona State Museum.
