ARC LTER (Image 4) In early June, the covers for the Arctic Long Term Ecological Research (ARC LTER) greenhouse in the tall willow and birch shrub plot are rolled down. The greenhouses are used to increase the summer temperature for several ecosystems in the arctic near Toolik Field Station. The covers are rolled up again in mid August. The ARC LTER site is part of a network of sites established by the National Science Foundation to support long-term ecological research in the United States. The ARC LTER research site is located in the foothills region of the North Slope of Alaska and is based out of the University of Alaska's Toolik Field Station, with the principal year-round institute based at The Ecosystems Center, Marine Biological Laboratory, Woods Hole, Mass. To learn more, visit the ARC LTER Web site. [Research supported by National Science Foundation grants DEB 04-23385 and DEB 06-20020.] (Date of Image: June 2001) [One of eight related images.
