Vertical methane fluxes in mesooligotrophic boreal peatland in European Northeast Russia

Abstract

This article presents data on vertical methane fluxes in mesooligotrophic peatlands of the middle taiga subzone by the eddy covariance method. We have found a link between the methane emission rate and the changes in groundwater level (GWL) and soil temperature at a depth of 10–20 cm in seasonal dynamics. The total methane emission from April to October was 22.4 g m−2; this value is higher than the values obtained by other authors in circumboreal peatland ecosystems.
