Notes: Inorganic carbon (IC) is from coulometric measurement of acid-evolved CO2. CaCO3 is calculated from IC × 8.33. Total carbon (TC), total nitrogen (TN), and total sulfur (TS) are from elemental analysis of sediments. TOCDIFF = total organic carbon from difference of TC and IC, TOCSRA = total organic carbon from source rock analyzer pyrolysis (see Table T18). ND = not determined.
