    dct:description "The 2.5-min isostatic gravity data set was produced by regridding the 4-km residual isostatic gravity grid of the U.S. The isostatic residual gravity grid was developed by the U.S. Geological Survey using an Airy Heiskanen model. Local compensation was computed with a depth of 30.0 km to the root for sites with sea level elevations and a density contrast of 0.35 g/cm3 across the bottom of the root." ;
