NMFS received an application from Furie Operating Alaska LLC (Furie) for a Incidental Harassment Authorization (IHA) to take marine mammals, by harassment, incidental to a proposed 3D seismic survey in Cook Inlet, Alaska, between May 2014 and May 2015. Pursuant to the Marine Mammal Protection Act , NMFS requests comments on its proposal to issue an IHA to Furie to take, by Level B harassment only, six species of marine mammals during the specified activity.
NMFS states in the Federal Register notice of this proposed seismic IHA: “Researchers have studied TTS in certain captive odontocetes and pinnipeds exposed to strong sounds (reviewed in Southall et al., 2007). However, there has been no specific documentation of TTS let alone permanent hearing damage, i.e., permanent threshold shift (PTS), in free-ranging marine mammals exposed to sequences of airgun pulses during realistic field conditions.”
Comments to NMFS on this proposed IHA are due on or before April 3, 2014.
