ARC LTER (Image 8) A mid August snowstorm covers the tundra with several inches of snow. The Arctic Long Term Ecological Research (ARC LTER) researchers dig out to sample soil water in an experiment to trace the movement of nitrogen from the tundra to streams and lakes and eventually to the Arctic Ocean. 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.
