        The 1997 Bay Area Seismic Imaging Experiment (BASIX-III) was the latest
in a series of USGS deep-crustal seismic reflection studies of the fault
geometry and crustal structure of the San Francisco Bay Area.  The specific
goal of BASIX-III was to investigate a 15 to 25 km deep zone of
high-amplitude seismic reflectivity that has been interpreted as a possible
sub-horizontal detachment linking the San Andreas and Hayward Faults.  A
twelve air gun source array, deployed from the M/V Auriga and a 2400 meter
hydrophone streamer deployed from the R/V William A. McGaw were used for
the data acquisition.  The streamer was laid directly on the bay floor at
five separate locations in San Francisco, San Pablo, and Suisun Bays and
remained stationary for two days at each recording site.  The air gun array
was towed past the streamer and out to offsets of 25 km and fired at
approximately 150 to 200 meter intervals. When data processing is
completed, the resulting images should better define the structural
relationship of the lower crustal reflective layer and the vertical
strike-slip faults that comprise the Pacific-North American plate boundary.
