Abstract:
The data was obtained by performing ramped pyrolysis and oxidation with 14C analysis of the emitted CO2 gases using the sedimentary residue of incubated permafrost soil (Yedoma) in seawater. The related data sets of the incubation experiment and experiment description can be found at doi:10.1594/PANGAEA.956711 and bacterial data at https://github.com/matthiaswietz/yedoma-bacteria. The ramped pyrolysis and oxidation setup is described in Hemingway et al. (2017a) and thermogram data conversion in E,p space is described in Hemingway et al. (2017b). Radiocarbon analysis was performed following Mollenhauer et al. (2021).
