Notes: IC = inorganic carbon, TC = total carbon, TOC = total organic carbon, Acid = determined by acidification method. BDL = below detection limit (CaCO3 = <1 wt%, TOC by either method = <0.03 wt%) as determined by three times the standard deviation of replicate measures of a low concentration sample. When CaCO3 is BDL, TOC is reported as equal to TC. ND = not determined (negative TOC wt%), — = no data.
