Figure F5. Site 1226 pore water profiles of delta18O-SO4, dissolved sulfate, and dissolved sulfide (SigmaH2S = HS–(aq) + H2S) and alkalinity vs. depth. delta18O-SO4 data are from this study. All other data are from D'Hondt, Jørgensen, Miller, et al. (2003). V-SMOW = Vienna-standard mean ocean water.
