For one half of both permafrost cores, the upper meter was subsampled into four layers each. From each layer, a small part was used for soil parameter analysis and a bigger part was used for an incubation (see doi:10.1594/PANGAEA.969148). For the soil parameter analysis, pore water was extracted after thawing the samples (n = 8) to measure pH, electrical conductivity and dissolved organic matter. Afterwards, remaining sediment was freeze-dried and the parameters TC, TOC, TN and delta C13 were determined. Additional pore water samples were used to determine SO4 and Cl content.
