    • f384nc.m77t - MGD77 data file for Geophysical data for field activity F-3-84-NC in Northern California from 06/15/1984 to 07/08/1984

    Metadata Updated: July 6, 2024

    Single-beam bathymetry and magnetics data along with DGPS navigation data was collected as part of field activity F-3-84-NC in Northern California from 06/15/1984 to 07/08/1984, http://walrus.wr.usgs.gov/infobank/f/f384nc/html/f-3-84-nc.meta.html. The geophysical source was a Knudsen 12 kHz 320B/R echosounder. 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/f/f384nc/html/f-3-84-nc.bath.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.
