CMG Scientists Meet with U.S. Army Corps of Engineers to Discuss Oil-Spill Hazards in San Francisco Bay
Paul Carlson, John Chin, and Florence Wong met with the U.S. Army Corps of Engineers to discuss the problem of shallow
bedrock knobs in central San Francisco Bay. These knobs of Franciscan Complex rocks rise from the bay floor to within
11 m of the water surface. Of the more than 4,000 ocean-going vessels that travel through west central San Francisco
Bay annually, more than 200 have drafts in excess of 12 m. When loaded, these deep-draft vessels draw more water than
is currently available over the bedrock knobs.
The Corps must decide whether and/or how they can lower the tops of the knobs below the hull depths of large ships
in order to avoid potentially disastrous oil spills in the bay. We met with geotechnical specialists in July and
biologists in August to show them some of our data, which should help address some of the technical and environmental
problems.
