Map seafloor geology and shallow subsurface stratigraphy of Monterey Bay 
Sanctuary
                  continental shelf to better understand the different benthic 
        environments of the
                  Sanctuary; attempt to define vertical profiles of current field in 
        upper 100-m of
         the water column using acoustic doppler system.

Bottom type (sand, mud, bedrock, bedrock charactistics, active sediment
         transport indications, biological seep communities or encrustations);
         Subbottom seismic stratigraphy and structure (stratigraphic style,
                  paleochanneling and terrace formation, fault activity, tectonic uplift 
        or
         subsidence, geologic history)

Seafloor geologic mapping using sonar side-scan (acoustic backscatter)
         imagery of the bottom.  Shallow subbottom profiling using a 1-kHz sound
                  source which gives information on stratigraphy to depths of about 50 
        meters.
                  Acoustic backscatter imagery, sub-bottom shallow seismic stratigraphy 
        in SEG-Y
         format, Acoustic Doppler Current Profiler data.

MACARTHUR CRUISE
Our weather-worn McArthur scientific crew returned to terra firma
on Sunday, having completed another 400 square km of mapping on the outer
shelf off Santa Cruz and Ano Nuevo. The outer shelf off Ano Nuevo was declared
by side-scan sonar watchstanders Galanis, Kinoshita, Medrano, Stevenson,
Eittreim, and Lewis to be perhaps the most boring piece of seafloor on the face
of the earth, with the possible exception of the deep Bering Sea. Now that it is
done, at least we'll never have to return again. Moderately high winds kept the
lively ship McArthur true to her reputation, although extraordinary skill in
line planning kept her moving either dead down-wind, or upwind, keeping the
rolls to a minimum. 400-m line spacing with the Klein 100 kHz side-scan and
1-kHz Geopulse high-resolution gives us a nearly complete and dense coverage
of the continental shelf of Monterey Bay proper. Last minute snafus in
scheduling nearly resulted in abandonment of the cruise, but our Marine Facility
folks pulled it out of the fire for us with some extraordinarily creative and
flexible manpower deployments, including Gann and Kooker onboard as technical
brainpower. Thanks to NOAA's PR savvy, the cruise was heavy with lots of
outreachy stuff: press conferences onboard on May 28 and June 2, resulting in
several TV news program scoops and articles in the SC Sentinel (front page), the
Monterey Herald, and other newspapers.
