surveys using magnetometry and ground-penetrating radar (GPR) were conducted at Anakena Beach on Easter Island, Chile. These geophysical surveys were performed to characterize the subsurface composition and structure of archaeological features at Anakena utilizing multiple near surface remote sensing techniques. Each data set informs on a unique part of the electromagnetic spectrum in the subsurface. Patterns of high and low amplitude readings can indicate the compositional structure of the deposits at Anakena. Recurring anomalies are evaluated by integrating data sets from the two techniques. This study primarily evaluates the data produced from GPR surveys and contrasts that data with information obtained from the magnetometry surveys. Background Despite its remote location, Easter Island has a dens
