NCHRP 25-25/Task 21: Assessment of Geophysical Remote Sensing Opportunities at State Departments of Transportation for Incorporation into Archaeological Investigations (Completed 2006)
Locating subsurface archaeological resources, delineating features within sites, testing for eligibility, and data recovery using historical excavation techniques dependent upon random sampling can be costly and inefficient. Too often, projects rely on “late discovery” clauses to handle previously unknown subsurface sites or sites with erroneously delineated boundaries or cultural features missed during the random sampling process. The cost for excavating sites using random sampling techniques is escalating, calling for the need to move to more efficient means of locating unknown sites and testing for cultural features within sites. Currently, no studies have compared the four major types of geophysical remote sensing technologies for archaeological resources: Resistivity, Magnetic Prospection, Ground Penetrating Radar, and Seismic. Traditionally these technologies have been used for intra-site analysis on known sites, excluding their potential for locating and delineating subsurface archaeological resources, and have been used mutually exclusive of one another.
The proposal is intended to be a focused approach using geophysical remote sensing to locate subsurface archaeological resources and to delineate cultural features within located/known sites. If done properly, this study could provide a means to streamline the environmental process for DOTs, provide better management information on archaeological resources, allow for integration of important cultural resource information early in the decision-making process, and in its broadest application, allow for collection of environmental data leading to development of climatic reconstruction’s. This proposal entails a systematic comparison of the four major geophysical remote sensing technologies to determine the following:
