s196wo.m77t and s196wo.h77t: MGD77T data and header file for single-beam bathymetry for field activity S-1-96-WO in Cascadia, Washington from 04/14/1996 to 06/06/1996

Single-beam bathymetry data along with GPS navigation data was collected as part of the U.S. Geological Survey cruise S-1-96-WO. The cruise was conducted in Cascadia, Washington from April 14 to June 6, 1996. The chief scientists were Mike Fisher from the USGS Coastal and Marine Geology office in Menlo Park, CA and Ernest Flueh from GEOMAR in Germany. The purpose of this cruise was for seismic studies of earthquake hazards posed by the subduction zone off Washington and Oregon. 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/s/s196wo/html/s-1-96-wo.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.
