Objective(s): To increase the understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems.
Project Description: The broad goal of this research is to increase our understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since we are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories: 1. Tundra-atmosphere fluxes - the exchange of carbon gases between the tundra and atmosphere is significant component of the carbon balance and is dependent upon vegetation cover. We have established 4 measurement sites near Daring Lake where these fluxes are measured annual during the late-winter and over the growing (summer) season. At each site a small (3 m high) meteorological tower has been set up. Instruments are mounted on the tower that measure carbon dioxide, heat, and water vapour exchanges, in conjunction with wind speed, solar radiation, temperature and ... Show more
