u571af.m77t: MGD77T data file for Geophysical data from field activity 71005 (U-5-71-AF) in Continental Margin Liberia from 10/30/1971 to 11/20/1971

Single-beam bathymetry, gravity, and magnetic data along with transit satellite navigation data was collected as part of field activity 71005 (U-5-71-AF) in Continental Margin Liberia from 10/30/1971 to 11/20/1971, http://walrus.wr.usgs.gov/infobank/u/u571af/html/u-5-71-af.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/u/u571af/html/u-5-71-af.bath.html http://walrus.wr.usgs.gov/infobank/u/u571af/html/u-5-71-af.grav.html http://walrus.wr.usgs.gov/infobank/u/u571af/html/u-5-71-af.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).
