l3a81nc.m77t - MGD77 data file for Geophysical data from field activity L-3A-81-NC in Central Coast, Northern California from 04/16/1981 to 04/26/1981

Single-beam bathymetry, gravity, and magnetic data along with DGPS navigation data was collected as part of field activity L-3A-81-NC in Central Coast, Northern California from 04/16/1981 to 04/26/1981, http://walrus.wr.usgs.gov/infobank/l/l3a81nc/html/l-3a-81-nc.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/l3a81nc/html/l-3a-81-nc.bath.html, http://walrus.wr.usgs.gov/infobank/l/l3a81nc/html/l-3a-81-nc.grav.html, and http://walrus.wr.usgs.gov/infobank/l/l3a81nc/html/l-3a-81-nc.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).
