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

Until recently it was assumed that all exchange of methane between forests and the atmosphere takes place at the soil surface, and can be captured by an understory eddy covariance (EC) system. Based on a comprehensive review just published in New Phytologist, it is now clear that all surfaces in a forest—living wood, dead wood,… More

While many people in the AmeriFlux community may be familiar with rice and methane emissions, most are usually surprised by the connection rice has to the state of Arkansas, which accounts for about half of U.S. rice production. Rice fields in Arkansas are concentrated in the eastern part of the state on the Mississippi River’s… More

Around midnight on Oct 24, while Dennis Baldocchi was sleepily re-deriving the conservation of mass equation, the AmeriFlux website released a major methane bubble and published the brand new (odorless) web presence for AmeriFlux’s first Action Theme Year—the Year of Methane! You can check out the Year of Methane objectives, projects, and collaborating partners, which… More

On behalf of co-authors Sara Knox, Rob Jackson, and Ben Poulter Inviting the entire flux community to participate! Take the survey. As part of a recent Global Carbon Project methane budget activity funded by the Moore Foundation, we are organizing the collection and aggregation of global CH4 data from the flux tower community in coordination with… More
