Deep soil warming experiment at the University of California, Blodgett Forest Research Station, located in Georgetown, CA, in the foothills of the Sierra Nevada mountains. Figure shows paired control (ambient temperature) and warmed (ambient +4oC) plots. Soil warming is achieved through heating cables to a depth of 1m below surface and has been ongoing for approximately 5 years. Infrastructure for measurement of temperature, moisture, gas fluxes, and dissolved constituents are shown. (Photo credit: Caitlin Hicks Pries)
