  • 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 survey in the Arctic Ocean, September-October, 2011. In 2011, NMFS adopted the National Science Foundation's (NSF) Environmental Assessment (EA) titled Marine Seismic Survey in the Arctic Ocean, September-October 2011. NSF's EA is based on report prepared by LGL Ltd., Environmental Research Associates titled Environmental Assessment of a Marine Geophysical Survey by the R/V Marcus G. Langseth in the Arctic Ocean, September-October 2011. NMFS has determined that the impact of conducting the seismic survey in the Exclusive Economic Zone of the U.S. and International Waters in the Arctic Ocean may result, at worst, in a temporary modification in behavior of small numbers of species of marine mammals. No injury, 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 and will not have an unmitigable adverse impact on the availability of marine mammal species or stocks tor taking for subsistence uses"--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.
