Models of in-pack chemical transformations have application to processes in seasonal snowpacks, temperate-region glaciers and polar snow/ice. For example, seasonal snowpacks accumulate “wet” and “dry” deposited material for several months each yea

Importantly, spring snow-melt is commonly the largest annual hydrologic event in temperate and polar areas and as such may be responsible for transporting pollutants rapidly over long distances.
