1 Sounds in the Sea: Acoustics and Marine Mammals Capital Hill Ocean Week - 2007 Reserve Officers Association One Constitution Avenue, NE Washington, DC Brandon L. Southall, Ph.D. (moderator) Director, NOAA Ocean Acoustics Program National Marine Fisheries Service Office of Science and Technology

2 Anthropogenic Sound and Marine Life Similarly, marine animals produce sound and listen for environmental acoustic cues. Underwater sound is very important in life history WHEN IS ANTHROPOGENIC SOUND A THREAT TO MARINE LIFE? WHAT CAN BE DONE TO MITIGATE IMPACTS WHILE ALLOWING ACTIVITIES VITAL TO NATIONAL & ECONOMIC SECURITY? Humans produce underwater sound either intentionally (sonar, seismic exploration, research, navigation) or incidentally (shipping, drilling, construction)

3 Anthropogenic Sound and Marine Life: Focusing Events and Recent Developments Focusing Events ATOC, mass stranding events Series of NRC reports, MM Commission FACA panel Broadening of the Issue Shipping, pile-driving, offshore wind farms, other active sonars Recognition that chronic sources may be as or potentially more significant for populations of animals than acute ones Recent Developments Rapid advancement in data-loggers and passive acoustic technology Marine mammal noise exposure criteria; fish and sea turtles International symposium (May 07) on vessel-quieting technologies Inter-agency Acoustics Task Force (14+ agencies; reports to JSOST)
