Methane Transport Pathways and Oxidation in a Minnesota Bog

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Despite the widely recognized importance of wetland CH4 emissions as a climate change feedback, simultaneous measurements of CH4 transport pathways and oxidation in a wetland are rare. Thus, these critical components of many CH4 models are poorly parameterized because of the lack of appropriate data.
