The micrometeorological eddy correlation technique was used to measure fluxes of methane and energy. Results from these measurements made in a Minnesota peatland are reviewed here. The field observations made in a pilot study (1990) demonstrated the utility of the eddy correlation technique for measuring surface fluxes of methane. Seasonal distribution of methane flux at the same site was obtained in a detailed study (May to October) in 1991. The evapotranspiration rates and other components of the surface energy budget were also quantified. The daily evapotranspiration during the measurement period (mid May to mid October) ranged from 0.9 to 6.0 mm day-1, with a seasonal average of 3.6mm day-1.
