Assume that the 8345 of SO4 in seawater is +20% and that Aso4-H25 = 60%. In a salt marsh, your seawater in the pore space will be slowly reduced to H2S. Make a curve showing how the 8³4504 signature will change as SO4 concentration goes down with sulfate reduction uin the soil. Assume a closed system. The concentration of sulfate in seawater is 30 mM. Justify which formula was used and why. Assume that the 8345 of SO4 in seawater is +20% and that Aso4-H25 = 60%.
