The temperature gradient was established by locating sites in the Fairbanks area that varied in elevation and aspect. Measurements include:soil temperature, forest aboveground production, litterfall, decomposition of litter and cellulose proxies, soil carbon dioxide efflux, moss photosynthesis, soil moisture, foliar isotopes (15N and 13C), and soil carbon and nitrogen. biogeochemistry Fairbanks Biogeochemistry
