Diving For Science 2009 Proceeding of the American Academy of Underwater Sciences 28th Scientific Symposium Neal W. Pollock Editor Atlanta, GA March 13-14, 2009 ii The American Academy of Underwater Sciences (AAUS) was formed in 1977 and incorporated in the State of California in 1983 as a 501c6 nonprofit corporation. Visit: www.aaus.org. The mission of AAUS is to facilitate the development of safe and productive scientific divers through education, research, advocacy, and the advancement of standards for scientific diving practices, certifications, and operations.

Diving for Science 2009. Proceedings of the American Academy of Underwater Sciences 28th Symposium. Dauphin Island, AL: AAUS; 2009. Scientific Diving and the Law: An Evolving Relationship Dennis W. Nixon College of the Environment and Life Sciences, University of Rhode Island, 9 East Alumni Avenue, Kingston, Rhode Island 02881, USA [email protected] Abstract This paper will review the development of both the American Academy of Underwater Science (AAUS) and the University – National Oceanographic Laboratory System (UNOLS). Casualties and their related legal implications were central to the development of both groups, as well the need for common safety and operational standards. The role of the scientific diving exemption under the Occupational and Safety and Health Administration (OSHA) rules, and the recent interest from the U.S. Coast Guard in revising commercial diving regulations will be discussed, along with three recent high-profile casualties that have focused attention on government and scientific diving. Keywords: OSHA, research vessel law, scientific diving law Historical Development of AAUS and UNOLS Both organizations have their beginnings in concerns over liability, and the special issues involved with conducting science at, or under, the sea. The origins of AAUS can be traced to the deaths of two scientific divers from Scripps in 1951, which led to the formation of the first scientific diving program in the United States. The goal of the
