  • Fig. 1 δ34S data of authigenic marine barite crystals across the PETM.

    The gray envelope denotes the 95% confidence interval of the LOESS regression (see supplementary materials). Shaded boxes indicate the extents of the main and total PETM interval (1). Error bars are 1σ.

  • Fig. 2 Model forcing and the resulting S-isotope ratios versus measured data.

    (A) Transfer of 32S into and out of the OMZ. (B) Resulting changes in the marine sulfate δ34S across the PETM. See supplementary materials for full model results. Note that in order to model the peak at 18.95‰, the timing of the flux changes has to be adjusted.
