Abstract

The greenhouse-gas (GHG) balance of CH₄ and N₂O emissions and CO₂ respiration in peatlands plays a key role in climate change. A GHG balance is mostly calculated from point measurements. In this study we propose and test a geophysical method of low frequency domain electromagnetic method (FDEM) as a proxy for forest-floor CO₂ respiration and CH₄ emissions in two 50 × 100 m drained peatlands in Estonia: a Downy birch and a Scots pine stand from April to September 2015. The FDEM measurement campaign in September 2015 yielded a detailed map of topsoil electrical conductivity. We explain the predictive power of FDEM on GHG emissions through relationships with dry bulk density of soil. Although we over- or underestimated some fluxes owing to soil heterogeneity, we composed reasonably credible GHG emission maps. The initial results seem promising and we recommend further application of FDEM methods.
