To their surprise, the researchers found that the samples from the thermokarst sites had lower levels of colored dissolved organic matter than did reference sites, suggesting that the carbon in the deeper soils exposed by thermokarst failure is significantly different from the carbon draining from the topmost, active layer of the permafrost, the team reports in the Proceedings of the National Academy of Sciences.
