j100sf.m77t and j100sf.h77t: MGD77T data and header files for single-beam bathymetry data for field activity J-1-00-SF in Grizzly Bay and Suisun Bay from 03/13/2000 to 03/14/2000

Single-beam bathymetry data along with GPS navigation data was collected as part of the U.S. Geological Survey cruise J-1-00-SF. The cruise was conducted in Grizzly Bay and Suisun Bay in the San Francisco Bay area, California from March 13 to March 14, 2000. The chief scientist was John Chin from the USGS Coastal and Marine Geology office in Menlo Park, CA. The purpose of this cruise was to study San Francisco Bay's response of bed morphology and surficial sediment texture to flow events. These 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/j100sf/html/j-1-00-sf.meta.html into MGD77T format provided by the NOAA's National Geophysical Data Center(NGDC). The MGD77T format includes a header (documentation) file (.h77t) and a data file (.m77t). More information regarding this format can be found in the publication listed in the Cross_reference section of this metadata file.
