Short summary
We investigate potential CO2 and CH4 production in degrading ice-rich permafrost in northeastern Siberia, deposited under different climatic conditions. With laboratory incubations, it could be shown that Late Pleistocene yedoma deposits generally produced more CO2 than Holocene deposits. Thus, OM decomposability needs to be interpreted against the paleoenvironmental background. However, OM decomposability cannot be generalized solely based on the stratigraphic position.
