From: Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter

Sulfate depletion versus the intensity of individual PARAFAC components (Fmax1, Fmax2, Fmax3, Fmax4) in quinine sulfate equivalents (QSU) within each sample. A linear regression for each component is shown, error bars represent standard error of the mean. Standard error of slope: C1: 0.023 ± 0.001, C2: 0.0083 ± 0.00034, C3: 0.004 ± 0.00023, C4: 0.0013 ± 0.0001.
