Spatial variations in snowpack chemistry, isotopic composition of NO3 and nitrogen deposition from the ice sheet margin to the coast of western Greenland

Data sets

Snowpack chemistry, nitrate stable isotopes and net deposition fluxes from the largest ice-free region in Greenland Chris J. Curtis, Jan Kaiser, Alina Marca, N. John Anderson, Gavin Simpson, Vivienne Jones, and Erika Whiteford

Short summary
Few studies have investigated the atmospheric deposition of nitrate in the Arctic or its impacts on Arctic ecosystems. We collected late-season snowpack from three regions in western Greenland from the coast to the edge of the ice sheet. We found major differences in nitrate concentrations (lower at the coast) and deposition load (higher). Nitrate in snowpack undergoes losses and isotopic enrichment which are greatest in inland areas; hence deposition impacts may be greatest at the coast.
