a Our estimate for the oceanic 13C Suess effect as of 1994. b Our estimate for the preindustrial δ13C-DIC obtained by correcting the global database4 for the oceanic 13C Suess effect. c The oceanic 13C Suess effect estimated by Eide et al. 1. d The preindustrial δ13C-DIC estimated by Eide et al. 33. e Difference between Eide et al. 1 and our estimate. f Difference between Eide et al. 33 and our estimate. g The 95% confidence interval for our estimated 13C Suess effect. h The 95% confidence interval for our estimated preindustrial δ13C-DIC.
