  • Description:
    "The National Marine Fisheries Service (NMFS) proposes to issue an Incidental Harassment Authorization (IHA) for the take, by Level B harassment only, of marine mammals during a marine geophysical (seismic) survey in the central-western Bering Sea, August 2011. In 2011, NMFS adopted the U.S. Geological Survey's (USGS) Environmental Assessment (EA) titled "Environmental Assessment of a Marine Geophysical Survey by the R/V Marcus G. Langseth in the central-western Bering Sea, August 2011," prepared by LGL Ltd., Environmental Research Associates. NMFS has determined that the impact of conducting the seismic survey in portions of the Exclusive Economic Zone of the U.S. and the international waters off of Alaska may result, at worst, in a temporary modification in behavior of small numbers of species of marine mammals. No injury (Level A harassment), serious injury, or mortality is anticipated to result from this activity, nor is it authorized. NMFS has further determined that this activity will result in a negligible impact on the affected species or stocks of marine mammals"--Cover letter; Portfolio comprised of three related PDF documents digitized and organized by: NOAA Office of Program Planning and Integration (PPI) National Environmental Policy Act (NEPA) staff.
