ABSTRACT
With an increasing rate of sea level rise inherently linked to climate change, numerous coastal archaeological resources are under threat. In Maine, virtually all 2000+ coastal aboriginal shell middens are eroding. Given limited time and resources, an efficient method for making informed cultural resource management decisions is critical. Herein, we describe a six-step protocol for a minimally invasive and cost-effective ground-penetrating radar delineation of shell midden size and morphology. Benefits of the survey methodology outlined in this study include the efficiency of data collection, the non-destructive aspect of the technique, continuous records of site stratigraphy, and the lower cost as compared to large-scale excavation. Two case studies are presented to illustrate the advantages and challenges associated with this method.
