Emerging Remote Sensing Methods in Underwater Archaeology

Abstract

As a critical first step in underwater research, the authors stress the importance of using geophysics for detecting, locating, and determining the extent of archaeological deposits. Magnetometry, multibeam depth sounding, side-scan sonar, sub-bottom profiling, airborne bathymetric LiDAR (ABL), and ground-penetrating radar (GPR) are discussed. The hydrographic GPR case study of stratigraphy and bathymetry took place at the Ryan-Harley site. The ABL case study took place at the Lake George Point Site.
