# SUPPLEMENTARY INFORMATION:

                    The subject permit is requested under the authority of the Marine Mammal Protection Act of 1972, as amended (MMPA; 16 U.S.C. 1361*et seq.*), the regulations governing the taking and importing of marine mammals (50 CFR parts 18 and 216), the Fur Seal Act of 1966, as amended (16 U.S.C. 1151*et seq.*), the Endangered Species Act of 1973, as amended (ESA; 16 U.S.C. 1531*et seq.*), and the regulations governing the taking, importing, and exporting of endangered and threatened species (50 CFR parts 17 and 222-226).                

                    Dr. Ketten is requesting a permit for the possession and worldwide import/export of marine mammal and endangered species parts from the orders of Cetacea (dolphins, porpoises and whales), Pinnipedia (seals, sea lions and walrus), Carnivora (sea otter,                     *Enhydra lutris*, and polar bear,                     *Ursus maritimus*) and Sirenia (dugongs and manatees). Whole carcasses, heads, or temporal bones (ears) are requested from stranded animals that die prior to beaching, are euthanized upon stranding, or which die in captivity. No animals would be taken or killed for the purpose of this research.                

                    The research proposed by Dr. Ketten utilizes three-dimensional analyses of aquatic mammals ears to generate estimates of auditory sensitivity, seeking to determine how structural elements of these ears contribute to underwater hearing. Mathematical models and three-dimensional reconstructions of                           ( print page 50894)                        head and ear anatomy are produced from whole carcasses, heads, or temporal bones from animals that strand and die or die in captivity. The tissues are scanned by CT (Computerized Tomography) and MRI (Magnetic Resonance Imaging) and the ears are decalcified, sectioned, digitized, and reconstructed. Measurements from these reconstructions are used to calculate frequency distribution maps for each species examined. These inner ear models have provided the first evidence of acute infrasonic hearing in some species, new insights into how marine mammals achieve extreme infra and also ultrasonic hearing, and estimates of species specific hearing curves. A permit is requested for a period of 5 years.                 

                    In compliance with the National Environmental Policy Act of 1969 (42 U.S.C. 4321*et seq.*), an initial determination has been made that the activities proposed are categorically excluded from the requirement to prepare an environmental assessment or environmental impact statement.                

                    Concurrent with the publication of this notice in the                     **Federal Register**                    , NMFS is forwarding copies of this application to the Marine Mammal Commission and its Committee of Scientific Advisors.
