Compiled relationship between thiosulfate (red circles) and sulfite (blue squares) concentrations in marine sediments in relation to the ambient concentration of free sulfide. Redrawn after Blonder et al. (2017). Log-log linear regressions are shown for thiosulfate (full line; R2 = 0.51) and sulfite (broken line; R2 = 0.57). For a complete discussion regarding the individual data points, the reader is referred to the original article.
