Data supporting sedimentary organic matter source reactivity and radiocarbon age analyses in the Bering Chukchi shelf to plateau system

This dataset supports the manuscript submitted to Global Biogeochemical Cycles on sedimentary organic matter source, reactivity, and radiocarbon age across the Bering Chukchi shelf to plateau system. The dataset includes station metadata, grain size data, bulk organic carbon and nitrogen contents, stable carbon and nitrogen isotope data, total hydrolysable amino acid and amino sugar data, derived organic matter reactivity indices, radiocarbon data, three endmember source apportionment results, and spatial province assignments. The dataset contains 60 surface sediment samples collected and analyzed in this study and 8 published stations from Li et al. (2023), as indicated in the Source column of the data tables.
