Abstract

Trace element concentrations have been measured in the air and in fresh and older surface snow during the summers of 1978 and 1979 at Dye 3, south-central Greenland. These data have been used with other information in the literature to calculate a total (wet plus dry) deposition velocity on the order of 0.5 cms-1 for trace element transport to the ice sheet on an annual basis. The data suggest that dry deposition contributes less than 25 % of the total transport for elements with large enrichment factors. Crustal elements may be more significantly influenced by dry deposition.
