Relocation of Major Ions in Snow along the Tundra-Taiga Ecotone (J.W. Pomeroy et al., 1993)
This research paper examines the spatial distribution and relocation of major ions in seasonal snowcover along the tundra-taiga ecotone near Inuvik, Northwest Territories, demonstrating that ion concentrations vary significantly by landscape type due to snow redistribution, temperature-gradient metamorphism, aerosol deposition, and photochemical processes. The study shows that while sulfate scales linearly with snow accumulation, sea-salt and calcium ions are enriched through dry deposition and aerosol scavenging mechanisms, with nitrate undergoing vaporization loss, resulting in a useful landscape-stratification method for extrapolating Arctic snow chemistry measurements across larger regions.
