Description Single-beam bathymetry data along with dead reckoning navigation data was collected as part of the U.S. Geological Survey cruise G-1-77-EG. The cruise was conducted in Yakutat Bay, Eastern Gulf of Alaska from April 27 to May 22, 1977. The chief scientist was Paul Carlson from the USGS Coastal and Marine Geology office in Menlo Park, CA. The geophysical source was a 3.5 kilohertz (kHz) system. 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/g/g177eg/html/g-1-77-eg.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. [More]
