| Summary: | Flux gradient, eddy covariance and relaxed eddy accumulation methods were applied to measure CH4 and N2O emissions from peatlands and arable land respectively. Fluxes of CH4 were measured above peatland in Caithness (UK) during May and June 1993 by eddy covariance and relaxed eddy accumulation methods. Emissions of CH4 from peatland changed with water table depth and soil temperature. A temperature response was also observed. The close similarity in average CH4 emission fluxes reported for wetlands in Caithness, Hudson Bay and Alaska in the range 11 to 40 μmol CH4 m-2 h-1 suggests that earlier estimates of CH4 emission from high latitude wetlands were too large or that the area of high latitudes contributing to CH4 emission has been seriously underestimated. -from Authors |
