Single-beam bathymetry data along with DGPS navigation data was collected as part of field activity K-1-78-AR in Barrows to Pt. Barrows, Arctic from 08/18/1978 to 09/18/1978, http://walrus.wr.usgs.gov/infobank/k/k178ar/html/k-1-78-ar.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/k/k178ar/html/k-1-78-ar.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).
