Carbon and mineral data of organic matter fractions in Siberian Yedoma permafrost

This file contains carbon and mineral data of organic matter fractions obtained from two permafrost drill cores L14-02 (73.33616° N; 141.32776° E) and L14-05 (73.34994° N; 141.24156° E) from Bol’shoy Lyakhovsky Island in NE Siberia in 2014. The datasets contain mass fractions of different size and d...

Description
Summary:This file contains carbon and mineral data of organic matter fractions obtained from two permafrost drill cores L14-02 (73.33616° N; 141.32776° E) and L14-05 (73.34994° N; 141.24156° E) from Bol’shoy Lyakhovsky Island in NE Siberia in 2014. The datasets contain mass fractions of different size and density fractions, OC concentrations, OC/N ratios, data on organic matter composition based on 13C-NMR, radiocarbon (14C) data, as well as data on iron (Fe) mineral phases and CO2 production rates of mineral-associated organic matter. Further, carbon and organic biomarker data (n-alkanes) of the bulk sediment are included. The data were created to study mass partitioning of Pleistocene permafrost OC among different organic matter fractions to assess the bioavailability and stability of the organic matter.
