Positron‐emitting radiotracers spatially resolve unexpected biogeochemical relationships linked with methane oxidation in Arctic soils

Abstract

Extensive permafrost thawing is currently underway in Arctic soils due to disproportionate Arctic region warming (Biskaborn et al., 2019). Previously frozen soil organic carbon (SOC) pools are entering active biogeochemical cycles and may be converted to greenhouse gases (GHGs; e.g.,
