Dissolved organic matter (DOM) leaching from thawing permafrost may have feedback effects on climate if it is efficiently mineralized into greenhouse gases (GHG). Yet, many uncertainties remain on the extent of this mineralization, which depends on DOM lability that is variable across landscapes and...
