In the first year of our research on the biophysical drivers of methane in a northern forest, our team conducted an intensive field campaign.

The team sampled 100 locations within the footprint of the Howland Research Forest eddy covariance tower. Samples were randomly selected and covered three drainage gradients: wetlands, dry uplands, and transitional soils. The team measured methane fluxes and environmental drivers at each location.

At a subset of 75 locations, the team collected soil samples for microbial analysis.

Automated chambers (gray) were installed in upland and transitional soils to capture frequent measurements of methane fluxes.

Trees were measured to estimate aboveground biomass.
