Navarin Basin - North Bering Sea, Alaska

Data Announcement 84-MGG-02

Approximately 1,600-line km of high-resolution seismic reflection data in the Navarin Basin, northern Bering Sea. The data were collected in August 1982 from the U.S. Geological Survey (USGS) Research Vessel S.P. LEE and deals with seafloor hazards pertinent to Outer Continental Shelf oil and gas lease sale activity. Microfile copies of the seismic records are available for purchase from the National Geophysical Data Center (NGDC) (now the National Centers for Environmental Information (NCEI)). The U.S. Geological Survey, Department of Interior has provided these data to NGDC (now NCEI) for public dissemination.

Three separate seismic reflection systems were operated simultaneously during the cruise, throughout much of the study area, providing high and intermediate frequency acoustic records, in addition to the high-resolution records. The systems were 3.5 kHz transducer, 400-800 Joule Uniboom, and two 40-80 cubic-inch airguns.


    Digital, navigation, bathymetry, magnetics and gravity are available on magnetic tape or CD-ROM.

    2 reels 35-mm Microfilm (Reel Nos. 2044, 2045)

    1 trackline map available in plastic sepia, paper sepia, and blackline.
