NMFS Proposes IHA for Seismic in the Beaufort and Chukchi
On August 17, 2012, the U.S. National Marine Fisheries Service published Federal Register notice of a draft Incidental Harassment Authorization for ION Geophysical's marine seismic survey in the Beaufort and Chukchi Seas, Alaska. NMFS proposes to issue this IHA pursuant to the Marine Mammal Protection Act. This proposed IHA authorizes ION to take marine mammals, by harassment only, during ION's seismic survey in the Beaufort and Chukchi between October and December 2012. Comments on this draft IHA are due to NMFS no later than September 17, 2012.
