S.F. BAY CRUISE
|
|
John Chin and Paul Carlson recently completed a cruise (J-1-98-SF)
|
|
in central San Francisco Bay during the January 8-23 period,
|
|
using the RV David Johnston.
|
|
The focus of the fieldwork was to document the nature and thickness of
|
|
Quaternary sediment.
|
|
|
|
We used the minisparker and ORE GeoPulse systems to obtain shallow subbottom
|
|
profiles.
|
|
A limited amount of Klein sidescan sonar data was also collected.
|
|
|
|
We will be mapping the new subsurface and surficial data and using it in
|
|
conjunction with the multibeam data collected in 1997 to investigate the
|
|
surficial and shallow subsurface deposits of central San Francisco Bay.
|
|
|
|
A secondary objective was to gather surface grab samples to obtain information
|
|
on the texture and distribution of surface sediments.
|
|
|
|
We collected 56 samples with a small Van Veen sampler.
|
|
This information will also be utilized by the San Francisco Bay project for
|
|
mapping of surficial sediment distribution and sediment transport studies
|
|
(Geist, Xu, and Rubin).
|
|
|
|
Chin and Carlson were ably assisted by Florence Wong, Ellen Tobey, and Justin
|
|
Friesner.
|
|
Mike Boyle and Larry Kooker did a great job of keeping electronic and navigation
|
|
gear running.
