Short summary

Adsorption/desorption incubations were conducted with tidal marsh soils to understand the differential sorption behavior of colored vs. noncolored dissolved organic carbon. The wetland soils varied in organic content, and a range of salinities of fresh to 35 was used. Soils primarily adsorbed colored organic carbon and desorbed noncolored organic carbon. Sorption capacity increased with salinity, implying that salinity variations may shift composition of dissolved carbon in tidal marsh waters.
