AmeriFlux showcased the Year of Methane action year at the 2019 Annual Meeting with an oral session, methane posters, and three methane breakout discussions. Ruminants, Forests, and Wetland Management The Year of Methane talks illustrated the variety of new directions enabled by methane flux measurement. Dave Hollinger, a Forest Service research scientist, gave the invited… More

The Pantanal is located in central South America, and is the largest continuous wetland in the world, covering a total flooding area of approximately 160,000 km2. Pantanal hydrology is highly seasonal, with peak flooding typically occurring in March in the northern part of the Pantanal and end of July in the southern part of the… More

Over the past decades, the eddy covariance (EC) community has clearly demonstrated the power of networks; regional networks and FLUXNET have shown us that combining data across multiple sites creates a whole that is greater than the sum of its parts. The FLUXNET database has been used extensively to evaluate satellite measurements, inform Earth system… 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
