−2 yr−1; before this, long-term rates ranged between 0.95 and 2.05 g m−2 yr−1. Pyrite S sequestration reflects accumulations both in organic horizons and in the submerged mineral soil. The rate of pyrite sequestration in organic horizons is generally driven by sea-level rise and the availability of reactive Fe. During the last 150 yr, the rates of pyrite accumulation averaged 7.2 ± 1.6 g m−2 yr−1; before this, long-term rates ranged between 0.53 and 1.14 g m−2 yr−1. Modeled predictions of pyrite and organic S accumulations in newly forming marshes during the next century were 15 ± 4.3 g m−2 yr−1 and 19 ± 8.2 g m−2 yr−1, respectively.
