Objective(s): To develop a model of the interacting biogeochemical and hydrologic processes that control the nutrient balance and primary productivity of the lakes in the Mackenzie Delta region, and ultimately a more general model for lakes associated with the flood plains and deltas of major world rivers; to identify and develop models of critical interlinkages between biogeochemical and hydrologic processes that are important to the ecological characteristics of Mackenzie Delta Lakes.

Project Description: Researchers will evaluate the spatial variability of nutrient chemistry during the snowmelt period within the drainage network of the tundra stream ecosystem. Evaluation of the controls on nutrient chemistry and community metabolism in streams withing the borel forest/tundra ecotone through the measurement of algae and organic matter in the stream. Evaluation of the potential role of Mackenzie Delta lakes of emitters of methane to the atmosphere.
