Small takes of marine mammals incidental to specified activities; offshore seismic activities in southern California.

Open Access Meeting documents, Notices 1995

National Oceanic and Atmospheric Administration

National Marine Fisheries Service (NMFS)
NMFS has received a request from the U.S. Geological Survey (USGS) for an authorization to take small numbers of marine mammals by harassment incidental to collecting marine seismic-reflection data in southern California waters. Under the Marine Mammal Protection Act (MMPA), NMFS is requesting comments on its proposal to authorize the USGS to incidentally take, by harassment, small numbers of marine mammals in the afore-mentioned area for a 3-week period between May and July 2000.
