GRAND RAPIDS, Minn.—Scientists are getting a glimpse of the future with a U.S. Department of Energy large-scale experiment designed to answer questions about how carbon-rich peatlands will respond to projected warming of the climate and increases in atmospheric carbon dioxide.
SPRUCE, which stands for Spruce and Peatland Responses Under Climatic and Environmental Change, was launched Wednesday, August 26, at the experiment site about 25 miles north of Grand Rapids. Among those attending the ceremony were Gary Geernaert and Daniel Stover of DOE’s Office of Biological and Environmental Research; Thomas Schmidt, assistant director for research, U.S. Department of Agriculture Forest Service Northern Research Station; and Martin Keller, associate laboratory director of Energy and Environmental Sciences at DOE’s Oak Ridge National Laboratory in Tennessee.
The site consists of about seven acres of raised bog in the peatlands of the Chippewa National Forest. The natural spruce bog in northern Minnesota contains more than 10,000 years of carbon accumulated from peatlands and answers to questions related to the predicted warming of ecosystems. [Read more…]
