Description

The dataset contains two tables and one figure. Table S1 presents sediment compositions and relevant parameters for iron-associated organic carbon and non-iron-associated organic carbon in three cores (YRE-4, SYS-12 and OT-8). Table S2 presents the relative abundances of organic carbon functionalities and ratios of carboxylic/aromatic and O-alkyl/aromatic in the three cores before and after reactive iron extractions. Figure S1 shows some selected carbon-1s NEXAFS spectra for sediments in the three cores before and after reactive iron extractions.
