For corrected total carbon (TC) with low-carbonate estuarine sediment calibration, if TC < 2.2 wt%, no correction was applied; if TC > 2.2 wt%, corrected TC = 2.2 + (x – 2.2) × 0.309. For corrected TC with high-carbonate La Luna shale calibration, if TC < 2.2/2.913, corrected TC = 2.913 × x; if TC > 2.2/2.913, corrected TC = 2.2 + (x – 2.2/2.913) × 0.901. Corrected total organic carbon (TOC) is corrected TC minus inorganic carbon (IC). Total nitrogen (TN) values are uncorrected with anomalous values removed.
