Project Description: This licence is issued for the scientific research application #932. The goal of this multi-disciplinary paleolimnological study will be employed to describe and further understand regional climate conditions, fire history, and ice cover duration spanning the past ~2000 years in the central Northwest Territories. The targeted study area is the southern portion of the Tibbitt to Contwoyto Winter Road. At least three indirect measures of climate and environmental change will be used: pollen (precipitation, temperature), microscopic charcoal (regional fire occurrence), and diatoms (ice cover duration, temperature, precipitation, various limnological parameters). A statistical approach will be used to differentiate micropaleontological and lithological stratigraphic zones. A paleoclimatological and paleoecological reconstruction based on known ecologies of identified taxa will be produced and compared to previous research in northwestern Canada. At least one sediment core will be collected. The sediment core will be 5 cm in diamter. They will collect as long a record as possible (in 1 meter sections vertically through the lake bed). Researchers may collect up to three sediment cores. If an appropriate bog is identified adjacent to a lake site, they may core the bog as well (this will provide comparable information to the data obtained from studying the lake core/s). The researchers will travel by truck to the Dome Camp of the Tibbitt to Contwoyto Winter Road. The researchers are willing to participate in scientific outreach in Yellowknife, please contact if an opportunity is available. The fieldwork for this study will be conducted from March 12 to December 31, 2009 at Armstrong Lake and Dome Lake.
