Chief scientist John Chin of the U.S. Geological Survey and co-chief scientist Don Reed of San Jose State University will lead this expedition to acquire and interpret a survey of the bay floor using high resolution seafloor mapping data.

• The primary objective of the survey is to identify shallow rocks that may provide hazards to navigation for large commercial ships in the San Francisco bay.
• A second objective is to determine the status of a bay floor site for the disposal of mud dredged from the shipping lanes of the bay.
• Lastly, you will examine the distribution of bay floor sediments, which are transported by the rapid currents associated with ebb and flow of the powerful tides in the bay. This process has implications for the movement of chemical pollutants and the stability of the bay floor.
