Incubation Data Assessing Biodegradability of Organic Carbon Mobilized from Permafrost Thaw Slumps (Peel Plateau, NT, Canada) Sarah Shakil, Suzanne E. Tank, Jorien E. Vonk, and Scott Zolkos

Short summary
Permafrost thaw-driven landslides in the western Arctic are increasing organic carbon delivered to headwaters of drainage networks in the western Canadian Arctic by orders of magnitude. Through a series of laboratory experiments, we show that less than 10 % of this organic carbon is likely to be mineralized to greenhouse gases during transport in these networks. Rather most of the organic carbon is likely destined for burial and sequestration for centuries to millennia.
