Abstract

Seasonal snow at the Earth’s surface contains a record of the chemistry in the atmosphere during snow crystal formation and subsequent snow pack accumulation. Solutes and other contaminants are incorporated into snow during crystal formation in the clouds, by scavenging and riming as the particles fall, and then by dry deposition. An established snow cover may represent the total chemical load on the environment integrated over several months. It is a widespread observation that this chemical load may be removed from the pack as an ionic pulse, with as much as 80 percent of the solutes eluting with the first 20 percent of the melt.
