**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.* ) and the regulations governing the taking and importing of marine mammals (50 CFR part 216).
The applicant proposes multiple studies to investigate how physiology supports and limits hypoxia tolerance in diving marine mammals. The applicant proposes to take 30 adult Weddell seals at an isolated dive hole and 36 free-ranging adult Weddell seals in Erebus Bay, Antarctica over two field seasons, with up to two unintentional mortalities proposed annually. Animals may be taken via capture, restraint, transport, anesthesia and sedation, external and internal instrumentation, biological sampling, marking, weighing, and ultrasound. The number of times an animal may receive a specific procedure is dependent on which of the four experimental groups it is assigned. Animals transported to remote breathing holes for dive tests will be held at the location for approximately six days before being returned to their original location of capture. Samples collected during these studies may be exported to the United States for analysis. While only 2 years of field study would be authorized, the permit would remain valid for 5 years to allow additional time for sample importation.
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 activity proposed is 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 the application to the Marine Mammal Commission and its Committee of Scientific Advisors.
