Robotic tools for deep water archaeology: Surveying an ancient shipwreck with an autonomous underwater vehicle

The goals of this field note are twofold. First, we detail the operations and discuss the results of the 2005 Chios ancient shipwreck survey. This survey was conducted by an international team of engineers, archaeologists and natural scientists off the Greek island of Chios in the northeastern Aegean Sea using an autonomous underwater vehicle (AUV) built specifically for high-resolution site inspection and characterization. Second, using the survey operations as context, we identify the specific challenges of adapting AUV technology for deep water archaeology and describe how our team addressed these challenges during the Chios expedition. After identifying the state-of-the-art in robotic tools for deep water archaeology, we discuss opportunities where new developments and research (e.g., AUV platforms, underwater imaging, remote sensing and navigation techniques) will improve rapid assessment of deep water archaeological sites. It is our hope that by reporting on the Chios field expedition we can both describe the opportunities that AUVs bring to fine resolution seafloor site surveys and elucidate future opportunities for collaborations between roboticists and ocean scientists.
