Single-beam bathymetry, gravity, and magnetic data along with DGPS navigation data was collected as part of field activity G-1-75-EG in Eastern Gulf of Alaska, Continental Shelf from 06/22/1975 to 08/27/1975, http://walrus.wr.usgs.gov/infobank/g/g175eg/html/g-1-75-eg.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/g/g175eg/html/g-1-75-eg.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).
