Archaeological Geophysics for DoD Field Use: A Guide for New and Novice Users

摘要: Abstract : Geophysics is the study of Earth by quantitative physical methods (including magnetometry, electrical resistance, conductivity, magnetic susceptibility and ground penetrating radar), which are used to detect, map, characterize subsurface phenomena including buried archaeological deposits. An effective use geophysics can improve reliability, reduce invasiveness and, in many cases, lower overall costs investigations (Hargrave, et al. 2002; Kvamme, 2006). Despite these potential advantages, adoption cultural resource management (CRM) practitioners United States has been very gradual. One reasons for this lack training opportunities. Although there some good short courses, such as annual National Park Service (NPS) workshop periodic Forest radar (GPR) workshops, much more extensive hands on experience needed archaeologists become informed consumers eventually geophysics. Furthermore, with only a handful US universities offering formal training, level geophysical expertise recent graduates programs provides little promise near future. Additional factors that have contributed slow U.S relatively high equipment methodological conservatism CRM regulatory agencies (e.g., State Historic Preservation offices) 2002). Confronted need or desire conduct survey, an archaeologist no familiarity faced considerable uncertainty regarding what instruments use, how time it will take, cost, collect, process, interpret data.
