Objective(s): To determine the rates of, and processes controlling: (1) the accumulation of snow, snowmelt and water flux through snowcovers; (2) the exchange of water between snowcover, the active ground layer and permafrost; (3) the movement of solutes and nutrients through the snowcover and to the stream channel; and (4) the effect of snow/soil temperature regime and vegetation types on runoff processes; to develop predictive models of snowmelt runoff.

Project Description: As part of a long-term study, this research will examine the important role that snow plays in northern ecosystems. Snow accounts for a large portion of yearly precipitation: when it melts, snow is a significant source of freshwater for refilling lakes and ponds, and for plant growth. This study will examine the role that snow plays in controlling streamflow and movement of solutes, nutrients and pollutants through the tundra, forest and delta ecosystems.
