u171gm.m77t - MGD77 data file for Geophysical data from field activity UGEOLEG_1 (U-1-71-GM) in Bay of Campeche, Gulf of Mexico from 05/27/1971 to 06/21/1971

Single-beam bathymetry, gravity, and magnetic data along with transit satellite navigation data was collected as part of field activity UGEOLEG_1 (U-1-71-GM) in Bay of Campeche, Gulf of Mexico from 05/27/1971 to 06/21/1971, http://walrus.wr.usgs.gov/infobank/u/u171gm/html/u-1-71-gm.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/u171gm/html/u-1-71-gm.bath.html http://walrus.wr.usgs.gov/infobank/u/u171gm/html/u-1-71-gm.grav.html and http://walrus.wr.usgs.gov/infobank/u/u171gm/html/u-1-71-gm.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).
