GHG characteristics and variations across climatic gradient in McKenzie Valley.

During the summer and fall of 2007, broad walks were laid out in tree distinct location in each site, along peatland-upland transition and in a collapse feature (internal lawn or collapse scar). Plots for ecosystem monitoring (vegetation, soil sampling and decomposition) were also set up in the nearby location. Within easy reach from a boardwalks, permanent gas sampling tubes (SAS tubes) were installed at the depth of 5, 10, 15, 20, 25 and 50 cm, for sampling soil CO2, CH4, and N2O production, and isotopic ratio. Passive gas flux chambers were constructed to determine the net CH4, N2O and CO2 fluxes to compliment the SAS tubes soil profile process. Permanent soil collars for measuring autotrophic, heterotrophic respiration and NEE were inserted in the ground in such way that they were not shaded by the boardwalk, to serve as a base for gas measuring equipment.
