The data measurements of CH4 and CO2 at different patch types (classified by dominant macrophyte vegetation or hydrological state). CH4 and CO2 data include 3 types of measurements: 1) Surface flux measurements from chamber measurements. 2) Leaf flux measurements from plant chambers, providing the rate per leaf area of methane flow through three species of macropyte aerenchemous plants (Water Lily, American Lotus, and Cattail) with the corresponding flux of CO2 at the same leaves. 3) Pore water concentrations of dissolved CO2 and CH4 concentrations. These are measured along vertical profiles at varying depths from the soil-water interface using in-situ porewater dialysis profiles (peepers). Observations of 1 and 3 are available monthly for most months of the growing season (May-September) of 2015, 2016 and 2018. Leaf flux measurements (plant chambers) are available only in June, July and August of 2018. We also included the patch type classification maps during 2015, 2017 and 2018 the relative water elevation map (bathymetry) for the site.In 8/23/2020 we added the data file ChamberFluxes_2018_Separated_Diffusive_Ebullitive_Fluxes.xlsx with observation related to chamber measurements in OWC during September 2018. In these observations, we partitioned the methane flux to its diffusive and ebullitive components, using an analysis approach we describe in section 5 of the methods "Ebullition and diffusion partitioning".
