Equipment Used
The primary purpose of the cruise was to obtain high resolution side-scan sonar 
imagery, bathymetry, and box cores to supplement previously collected data with 
the aim of producing an interpretive map of bottom types for the South Bay.
The Klein and Mudseis systems were utilized to obtain digital imagery
in three primary areas that had been previously mapped: 1) the main tidal
channel with its sedimentary furrows; 2) the shallow area east of San Bruno
Shoal with its variety of bottome types; and 3) the deep area east of Hunters
Point running north to the Bay Bridge which has light and darktonal patches.
Results from this cruise showed that the bottom morphologies had changed very
little since previously mapped. In particular, the furrows observed nearly 10
years ago in the main tidal channel are still present and are still aligned with
their axes parallel to the channel axis. The dark tonal patches near Hunters
Point appear to be due to the presence of scattered and discontinuous coarse
debris disseminated in a matrix of mud and sand sediment.
