Single-beam bathymetry, gravity, and magnetic data along with DGPS navigation data was collected as part of field activity L-6-77-EG in Eastern Gulf of Alaska from 06/13/1977 to 06/30/1977, http://walrus.wr.usgs.gov/infobank/l/l677eg/html/l-6-77-eg.meta.html 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/l/l677eg/html/l-6-77-eg.bath.html, http://walrus.wr.usgs.gov/infobank/l/l677eg/html/l-6-77-eg.grav.html, and http://walrus.wr.usgs.gov/infobank/l/l677eg/html/l-6-77-eg.mag.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).
