Ramped pyrolysis/oxidation radiocarbon data for river sediment, soil, and bedrock from the Canning River drainage basin, Alaska (2022-2024)

We used ramped pyrolysis/oxidation radiocarbon (RPO-14C) analyses to investigate spatial and temporal variations in the thermochemical stability and relative ages of fluvial particulate organic carbon (POC), soil organic carbon, and rock organic carbon in the Canning River drainage basin in northeastern Alaska. This dataset includes thermogram data (CO2 released from a sample as a function of RPO thermal oxidation temperature), activation energy distribution data, and radiocarbon and stable carbon isotope data for distinct RPO fractions for each sample. Activation energy distributions were calculated from the thermogram data using the RampedPyrox package (Hemingway et al., 2016). References: Hemingway, J. D.
