Objective(s): To understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region.

Project Description: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplands.

Field methods will include collection of samples from small, shallow soil pit approximately 100 cm long, 75 cm wide, and 100 cm deep. Pits will be excavated with hand shovels until frozen soil is encountered, and further excavation will be done using a small, hand-held, gasoline-powered jackhammer. Cores of frozen soil will also be extracted from sampling locations using a hand-held, gasoline-powered coring drill. At some locations, soil temperatures, air temperatures, and snow depth will be measured using automated sensors installed in narrow boreholes.

The researcher is happy to prepare plain-language posters explaining the research and results for posting and distribution at the discretion of Aurora Research Institute. The researcher is also willing to present an explanation of the research and results at Aurora Research Institute or another community venue if there is interest. Any publications or reports resulting from this research will be distributed to the Inuvik and Aklavik Hunters and Trappers Committees.

The fieldwork for this study will be conducted from June 28, 2013 to September 6, 2013.
