Short summary
This study is the first to examine how permafrost slumping affects dissolved organic carbon (DOC) mobilization in landscapes dominated by glacial tills. Unlike in previous studies, we find that slumping is associated with decreased DOC concentrations in downstream systems – an effect that appears to occur via adsorption to fine-grained sediments. This work adds significantly to our understanding of varying effects of permafrost thaw on organic carbon mobilization across diverse Arctic regions.
