Short summary
This study presents, for the first time, a characterisation of soil organic matter from the Gydan Peninsula in the Yamal Region, Western Siberia, Russia. We provide evidences that soils in this region accumulate lowly decomposed organic matter with a high mineralisation potential. This emphasises the vulnerability of this soil carbon pool to be remobilised as CO2 to the atmosphere under climate warming effects.
