Mineralogical characteristics, TOC-based properties and terrestrial component loadings in two river-marginal sea systems

This dataset includes mineralogical characteristics (surface area and mean grain size), TOC-based properties (TOC% and TOC-δ13C) and terrestrial component loadings (terrestrial organic carbon, long-chain n-alkanes and n-fatty acids (n-FAs)) in riverine suspended particulate matter (SPM) and coastal surface sediments of the Pearl River-northern South China Sea and the Yellow River-Bohai Sea/Yellow Sea.
