Welcome to the homepage of the UM Biological Station AmeriFlux Core Site Project. Our research focuses on understanding the long-term dynamics of carbon, water, and energy exchange over natural vegetation in north-central North America, with an emphasis on forested landscapes of the upper Great Lakes region. We have a particular interest in how climate variability and ecological succession and disturbance influence biosphere-atmosphere interactions.

At this site you will find in-depth descriptions of our four contributing eddy covariance flux towers and links to data products, publications, research opportunities, and project personnel.

Much of our work and core infrastructure is located at the University of Michigan Biological Station (UMBS) located in northern lower Michigan. We operate in close association with the AmeriFlux network of research facilities distributed across the Americas and are one of the Core AmeriFlux sites supported by the U.S. Department of Energy through the Lawrence Berkeley National Laboratory (LBL).

At this time we are involved with four tower sites:

At UMBS, we run the US-UMB and US-UMd towers. The US-UMB tower has been in continuous operation since 1999 and the US-UMd tower since 2008.

At the Sylvania Wilderness and Recreation Area in the western Upper Peninsula of Michigan we collaborate in the operation of the US-Syv tower with the Chequamegon Ecosystem-Atmosphere Study (ChEAS).

At the Olentangy River Wetland Research Park in central Ohio we run the US-ORv tower. Data from other flux campaigns over inland and marine waters can be found here as well.

Primary funding for the first 12 years of operation of the US-UMB tower was through the U.S. Department of Energy (DOE), National Institute for Environmental Change (NIGEC) and the National Institute for Climate Change Research (NICCR). From 2011 to 2014 primary funding of all tower operations was through the DOE, Office of Biological and Environmental Research, and since 2015 through LBL.
