Notes: IC = inorganic carbon; CaCO3 = calcium carbonate; TC = total carbon; TOC = total organic carbon; TN = total nitrogen; TS = total sulfur; and C/N = carbon/nitrogen ratio. TOC concentrations are calculated from the difference between IC and TC concentrations. C/N ratios are calculated from TOC and TN concentrations and are given as atom/atom ratios.
