Draft Acoustic Guidance for Assessing the Effects of Anthropogenic Sound on Marine Mammals - Auditory Impacts.

Docket ID: NOAA-NMFS-2013-0177
Agency: National Oceanic and Atmospheric Administration (NOAA)
Parent Agency: Department of Commerce (DOC)
The National Marine Fisheries Service and the National Ocean Service (referred collectively here as the National Oceanic and Atmospheric Administration (NOAA)) has developed draft guidance for assessing the effects of anthropogenic sound on marine mammal species under NOAA’s jurisdiction. The guidance provides updated received levels, or acoustic threshold levels, based on the best available science, above which individual marine mammals are predicted to experience changes in their hearing sensitivity (either temporary or permanent) for all underwater anthropogenic sound sources. This guidance is intended to be used by NOAA analysts and managers and other relevant user groups and stakeholders, including other federal agencies, when seeking to determine whether and how their activities are expected to result in particular types of impacts to marine mammals via acoustic exposure. Although NOAA has updated the acoustic threshold levels from those previously used, and these changes may necessitate new methodologies for calculating impacts, the application of the thresholds in the regulatory context under applicable statutes (Marine Mammal Protection Act, Endangered Species Act, and National Marine Sanctuaries Act) remains consistent with past NOAA practice.
