Carbon inventory of Siberian Yedoma and thermokarst deposits
During the late Quaternary, a large pool of organic carbon accumulated in the ice-rich syngenetic frozen deposits and soils preserved in the arctic and subarctic permafrost zone. Because of the potential release of organic carbon from thawing permafrost, the organic-matter (OM) inventory in Yedoma d...

We analyzed OM characteristics like organic carbon content, stable carbon isotopes and carbon-nitrogen ratios.
