Description:
Spatial variations in snowpack chemistry and isotopic composition of NO 3 − along a nitrogen deposition gradient in West Greenland Chris J. Curtis, Jan Kaiser, Alina Marca, N.

We collected late season snowpack from 3 regions of W 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 at the coast). Nitrate in snowpack undergoes losses and isotopic enrichment which are greatest in inland areas, hence deposition impacts may be greatest at the coast.
