Book excerpt: The Acoustic Thermometry of Ocean Climate (ATOC) project was a feasibility study to determine 1) the precision with which acoustic methods could be used to measure large-scale changes in ocean temperature and heat content and, 2) the effects, if any, that the acoustic transmissions would have on marine mammals and other marine life. Two sound sources were installed for this project, one on Pioneer Seamount off central California and one north of Kauai. Each of the sound sources transmitted for 24 months in accordance with marine mammal study protocols. The results from the study indicated that 1) acoustic thermometry is a powerful tool for making routine measurements of large-scale ocean temperature variability and heat content, as originally hypothesized, and 2) acoustic travel times can be measured with a precision of 20-30 milliseconds at 3000-5000 ranges. During the Marine Mammal Research Programs conducted in both California and Hawaii, there were no observations of overt or obvious short-term changes in the behavior, abundance, distribution, or vocalizations of marine mammals in response to the ATOC sound source transmissions. Although some subtle effects were revealed through statistical analyses, bioacoustics experts have concluded that these effects would not adversely affect the survival of an individual whale or the status of the North Pacific humpback whale population.

Book excerpt: After global warming became a concern in the mid-1950s, researchers proposed measuring deep ocean temperatures to reveal any significant trends in core ocean warming. Acoustic thermometry can detect changes in ocean temperature by receiving low-frequency sounds transmitted across an ocean basin because the speed of sound is proportional to water temperature. Acoustic Thermometry of Ocean Climate (ATOC) is an international program involving 11 institutions in seven nations. It is designed as a 30-month "proof-of-concept" project to provide data on possible global climate change, with funding provided by the U.S. Department of Defense. A Marine Mammal Research Program (MMRP) was established as part of ATOC to assess the effects of ATOC sound signals on marine mammals. The proposed ATOC sources will be located 15 kilometers off the coast of Kauai, Hawaii, and near the Pioneer Seamount in California. A debate has arisen over ATOC's impact on marine mammals versus the benefits of better global warming information derived from it. Among the concerns are questions regarding the effects of low-frequency sound on marine mammals, and the baseline data available on marine mammals near the proposed source locations. In response to concerns expressed by the public, environmentalists, scientists, and Congress, the National Marine Fisheries Service (NMFS) held a series of public hearings on the Marine Mammal Protection Act (MMPA) permit applications by Scripps Institution of Oceanography for ATOC. Consequently, ATOC was delayed until draft environmental impact statements could be prepared. The Office of Naval Research funded a National Research Council (NRC) investigation of current knowledge and research needs with respect to the effects of low-frequency sound on marine mammals. The NRC report, released in March 1994, concluded that the data were insufficient to determine the possible effects of low-frequency sound on marine mammals.

Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the general criteria for choosing a site for ATOC cabled sources. In particular, the process of selecting the California site is reviewed. Two possible locations are considered, Pioneer Seamount and Sur Ridge. The Sur Ridge site has been selected because a requisite marine mammal research program can be conducted there for less cost. Ocean acoustics, Acoustic projectors, Global change.

Available in PDF, EPUB and Kindle. Book excerpt: The ATOC acoustic source was installed on Pioneer Seamount during October and November 1995. Three vessels were used for this work. On 5 October, M/V McGaw laid 3 nmi of cable at Pillar Point, California. The cable is terminated at the Pillar Point Air Force Station. On 14 October, a survey of the proposed source site on Pioneer Seamount was conducted using the U.S. Navy's Deep Submergence Vehicle Sea Cliff (DSV 4) deployed from MW Laney Chouest. This survey determined the precise location for tne source and deployed acoustic transponders for relocating the site. The source deployment using M/V Independence was done in four steps during 24 October to 3 November. One length of deep stowed cable was recovered off Point Sur. The source was deployed on 28 October, and this first length of cable laid toward shore. A second piece of deep stowed cable was recovered off San Simeon. It then was spliced to the first piece, laid to shore, and spliced to the cable at Pillar Point. Engineering test transmissions were made after deployment of the source to ensure that it was functioning correctly. The best estimate for the position of the center of the acoustic source is 37deg2O.5550'N, 123deg26.7117'W at 938.7 m depth.
