ORNL ecologists are working this summer to identify rooting patterns for plants that inhabit polygonal ground on the Barrow Environmental Observatory (BEO). Considerable diversity in root distribution and architecture is being observed, information that will eventually be included in models of plant functional types.

Recap of Town Hall Meeting held December 8, 2011
The Terrestrial Ecosystem Science (TES) program within the U.S. Department of Energy’s Office of Science supports basic research to improve representation of critical terrestrial ecosystem processes in Earth System Models. This town hall meeting presented a vision and funding strategy while highlighting the Next-Generation Ecosystem Experiment (NGEE) project, a major 10-year research effort in the Arctic.

NGEE Review


The Next-Generation Ecosystems Experiment (NGEE) project was recently reviewed by a national and international panel of experts. Participants in the NGEE projects presented their concepts for using field, laboratory, and modeling studies to address how permafrost degradation in a warming Arctic, and the associated changes in landscape evolution, hydrology, soil biogeochemical processes, and plant community succession, will affect feedbacks to the climate system.
