The Arctic is a hot spot of warming triggering methane releases from thawing permafrost. This study by Castro-Morales and Co-Workers provides new insights into the transport of methane from soil to rivers. This work makes an essential contribution to comprehending the magnitude of methane emissions in Arctic rivers and potential contribution to the global methane budget under climate change.
Short summary
Permafrost thaw releases methane that can be emitted into the atmosphere or transported by Arctic rivers. Methane measurements are lacking in large Arctic river regions. In the Kolyma River (northeast Siberia), we measured dissolved methane to map its distribution with great spatial detail. The river’s edge and river junctions had the highest methane concentrations compared to other river areas. Microbial communities in the river showed that the river’s methane likely is from the adjacent land.
