The Aspen FACE (Free-Air Carbon Dioxide Enrichment) Experiment is a multidisciplinary study to assess the effects of increasing tropospheric ozone and carbon dioxide levels on the structure and function of northern forest ecosystems. Aspen FACE continued in 2010 as the Northern Forest Ecosystem Experiment (NFEE), funded by the US Forest Service. Original trees were harvested during 2009 and a new forest vigorously sprouted under the FACE treatments in 2010 before treatments were discontinued. Researchers interested in data or samples from FACE and NFEE should fill out a research registration form using the link above. Located at the Harshaw Experimental Forest near Rhinelander, Wisconsin, the Aspen FACE Experiment operates as a DOE User Facility , and is a collaborative effort among the following organizations: Michigan Technological University US Forest Service Northern Research Station Brookhaven National Laboratory (FACTS I) Natural Resources Research Institute University of Michigan University of Wisconsin, Madison Estonian Academy of Science Canadian Forest Service Slovak Forest Resources Institute Academy of Finland University of Nevada-Reno Distribution of species within ring. The Aspen FACE experiment consists of twelve 30m rings in which the concentrations of carbon dioxide and tropospheric ozone can be controlled. The design provides the ability to assess the effects of these gasses alone, and in combination, on many ecosystem attributes, including growth, leaf development, root characteristics, and soil carbon. Each ring consists of a series of vertical ventpipes which disperse carbon dioxide, ozone or normal air into the center of the ring. This computer controlled system uses signal feedback technology to adjust gas release each second in order to maintain a stable, elevated concentration of carbon dioxide and/or ozone throughout the experimental plot. Because there is no confinement, there is no significant change in the natural, ambient environment other than elevating these trace gas concentrations.
