A comparative assessment of underwater visual survey tools : results of a workshop and user questionnaire Assessment of underwater visual survey tools

"Visual surveys of seafloor habitats and associated organisms are being used more commonly in marine science, and yet researchers and resource managers continue to struggle in choosing among available underwater tools and technologies. In this report, we present the results of a comprehensive questionnaire and corresponding workshop that address the capabilities, limitations, operational considerations, and cost for five mobile, visual tools used in survey mode: remotely operated vehicles (ROV); autonomous underwater vehicles (AUV); human-occupied vehicles (HOV); towed camera sleds (TCS); and human divers (scuba). These tools were considered specifically in the context of their use during standardized surveys of benthic organisms (i.e., fishes, megafaunal invertebrates) and their seafloor habitats"--Executive Summary.
