Autonomous Underwater Vehicles (AUVs) are swimming robots whose use promises to revolutionize our scientific understanding of aquatic ecosystems. AUVs sample the environment at spatial and temporal scales that would be prohibitively expensive using conventional technology. Other tasks
well-suited for AUVs include automated gathering of environmental data used for monitoring ecosystem health and marine food resources, facilitating search and recovery operations and drug traffic interdiction, and increasing national security. However, increasing operations of greater numbers
and kinds of AUVs in situations where scientific diving occurs pose a potential hazard that needs to be addressed. We review scenarios where AUV/diver conflicts are likely to occur, make estimates of the scope of the problem, and offer some initial thoughts concerning threat mitigation. Ultimately,
a ’consensus standard’ will be needed with contributions from the emerging AUV robotics industry, AUV academic R&D centers, military us ers, the commercial, scientific, and recreational diving community, and civilian agencies concerned with maritime commerce, marine science,
and human safety.
