From an operational comfort perspective (science be damned), ideally located flux sites should be placed somewhere easily accessible, near power connection and wireless data coverage, and, preferably, on solid ground. Old Woman Creek has none of the above. Located at the center of a Lake Erie coastal wetland, US-OWC hits all the high notes of… More

  The contrast in weather was extreme for 2020 and 2021 at our flux sites located in the semiarid shrublands, grasslands, savannas, and forests of southern Arizona. This was especially true at the Santa Rita Mesquite Savanna site (US-SRM in AmeriFlux vernacular) which had the driest summer monsoon growing season on record in 2020 (42… More

Coastal forested wetlands in the southeastern US provide important ecosystem services, including the conservation of biodiversity, supplying clean, abundant water resources, and the cycling and storage of carbon, which feeds back to stabilize regional climate (Noormets et al., 2010; Sun et al. 2010; Aguilos et al. 2020). However, large areas of these wetlands have been… More

We all know the importance of soil as a CO2 source to the atmosphere, even in high latitude/altitude ecosystems with persistent snow cover. Before the days of automated soil respiration chambers and accessible eddy covariance technology, CO2 fluxes through porous media were estimated using vertical CO2 concentration profiles coupled with assumption that the vertical profile… More

The Rosemount AmeriFlux sites are located at the University of Minnesota, Rosemount Research and Outreach Center (RROC) – a 3,500 acre research farm (https://rroc.cfans.umn.edu/). Our eddy covariance sites were established in conventional corn/soy systems in the early 2000s to assess the long-term carbon balance of agricultural systems and to evaluate if practical strategies (i.e. cover… More

Thank you for attending the 2021 AmeriFlux Annual Meeting! All of you made possible a wonderful 3 day conference, in which we enjoyed catching up with colleagues, meeting new ones, and brainstorm new directions for high impact science around eddy covariance fluxes. We’d like to thank the speakers, panelists, breakout leads, poster presenters, and everyone… More

Congratulations to the several AmeriFlux community members who have been awarded DOE funding for eddy-covariance flux research! In total, $11 million in funding was announced “to Study Critical Ecosystems and Improve Climate and Earth System Modeling.” Notably, three of the PIs benefitted from the AmeriFlux support through the AmeriFlux Rapid-Response Flux System (RRS) program, the… More
