Measured properties of the Antarctic ice sheet derived from the SCAR Antarctic digital database
Abstract The completion of the SCAR Antarctic digital database (ADD) has provided a new basis for statistical calculations for Antarctica: data-sets are available at the scale of the original source material, and generalised to 1:1,000,000, 1:3,000,000, 1:10,000,000, and 1:30,000,000. The new descri...
