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.

探地雷达作为评估侵蚀贝壳凹陷的文化资源管理工具

摘要随着与气候变化内在联系的海平面上升速度的加快，许多沿海考古资源正受到威胁。在缅因州，几乎所有2000多个沿海原住民的贝壳中都在侵蚀。在有限的时间和资源的情况下，制定明智的文化资源管理决策的有效方法至关重要。在这里，我们描述了一个六步协议，用于以最小的侵入性和具有成本效益的穿透地面的雷达描绘中壳尺寸和形态。这项研究概述的调查方法的优点包括数据收集的效率，技术的无损方面，现场地层的连续记录以及与大规模开挖相比较低的成本。提出了两个案例研究，以说明此方法的优点和挑战。
