Description:"The National Marine Fisheries Service (NMFS), Office of Protected Resources (OPR), proposes to issue a scientific research permit for takes of marine mammals in the wild, pursuant to the Marine Mammal Protection Act of 1972, as amended (MMPA; 16 U.S.C. 1361 et seq.). The primary objective of the proposed research is to support conservation management by providing empirical measurements of behavior in marine mammals and behavioral changes as a function of sound exposure. The permit applicant would observe behavioral responses in several marine mammal species exposed to controlled underwater sound exposures and quantify exposure conditions associated with various effects. This information would be used to determine the acoustic exposures of mid-frequency (MF) sonar sounds that elicit an identifiable behavioral indicator response in targeted marine mammals, so that sound producers and regulatory agencies can better understand, minimize, and manage noise impacts on protected species. Additionally, the applicant proposes to conduct photo-identification of marine mammals and collect skin samples for genetic analysis. The action area for the proposed study includes the U.S. Navy's existing Southern California (SOCAL) Range Complex, other US locations including offshore waters, and international waters throughout the Pacific basin. Scientific research permits are generally categorically excluded from the National Environmental Policy Act of 1969 (NEPA; 42 U.S.C. 4321 et seq.) requirements to prepare an environmental assessment (EA) or environmental impact statement (EIS) (NAO 216-6). However, NMFS chose to prepare an EA as a more detailed analysis of potential environmental impacts"--Abstract (p. i).
