The cruise was conducted in Grizzly Bay and San Pablo Bay in the San Francisco Bay area, California from March 22 to March 27, 2000. The chief scientist was Bruce Jaffe from the USGS Coastal and Marine Geology office in Menlo Park, CA. The purpose of this cruise was for ground truthing, and to collect box cores and gravity cores.\nThese data are reformatted from space-delimited ASCII text files located in the Coastal and Marine Geology Program (CMGP) InfoBank field activity catalog at http://walrus.wr.usgs.gov/infobank/j/j200sf/html/j-2-00-sf.meta.html into MGD77T format provided by the NOAA's National Geophysical Data Center(NGDC).
