North of Boston lies the Great Marsh, the largest remaining complex of salt marshes in New England. Here, the Plum Island Ecosystems LTER is studying long-term changes in coastal ecosystems, particularly those due to an acceleration in sea level rise. In contrast to most southern marshes, the Great Marsh is currently dominated by Spartina patens… More

Tucked away on the remote Seward Peninsula in the far west of Alaska lays the Arctic outpost for the Department of Energy’s Next Generation Ecosystem Experiment (NGEE-Arctic) and its associated AmeriFlux site (US-NGC). During the summer months each year, when US-NGC is accessible by road, blueberries fruit across the surrounding tundra and river valleys, attracting… More

The inhibition of leaf respiration in the light has long been reported at a leaf scale, but recent isotopic evidence suggests that inhibition also occurs at the ecosystem scale. This is important, as inhibition at the ecosystem scale would imply a significant bias in current estimates of ecosystem photosynthesis and respiration, but it is not known… More

By Chad Hanson, AMP Tech Team. Many flux sites do not have access to line power, and run on solar power. This post shares my recent experience of building a simple solar system, and the design considerations that went into it. We hope this will help others as they design and maintain their own systems. Please use the Comments at the… More
