| Description |
Single-beam bathymetry, gravity, and magnetic data along with transit satellite navigation data was collected as part of field activity UGEOLEG_3 (U-3-71-CB) in Eastern Greater Antilles, Caribbean from 07/17/1971 to 08/04/1971, http://walrus.wr.usgs.gov/infobank/u/u371cb/html/u-3-71-cb.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/u/u371cb/html/u-3-71-cb.bath.html http://walrus.wr.usgs.gov/infobank/u/u371cb/html/u-3-71-cb.grav.html and http://walrus.wr.usgs.gov/infobank/u/u371cb/html/u-3-71-cb.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). More information regarding this format can be found in the publication listed in the Cross_reference section of this metadata file. [More]
