    dct:description "Airborne gravity data for North Carolina, South Carolina, Virginia, and the Atlantic Ocean collected in 2013 and 2014 over two surveys. This data set is part of the Gravity for the Re-definition of the American Vertical Datum (GRAV-D) project initiated by NOAA's National Geodetic Survey to collect and monitor gravity data suitable for the re-definition of the vertical datum for at least the United States and territories. The data is available at http://www.ngs.noaa.gov/GRAV-D/data_es04.shtml in ASCII text format." ;
