    Abstract

    The relationships between hydrological dynamics. geochemical heterogeneity and dissolved organic carbon (DOC) structural
    characteristics were determined in an acidic groundwater dependent wetland. Multiple analytical tools were used to quantify
    changing DOC characteristics in both surface water and groundwater, over time. Complexation between pH, Fe, Al and
    DOC In the wetland were interrelated and seasonally driven by hydrological connectivity. DOC conformation and reactivity
    changed rapidly in response changing hydrological conditions, with implications for the role of DOC in wetland ecology. This
    work highlighted the risk associated with relying on synoptic water monitoring with little regard for hydrological connectivity
    conditions.
