The elements Fe, C and O cycle through a variety of oxidation states in the biosphere. We hypothesize these cycles are co-dependent through the intermediacy of reactive oxygen species (ROS), where both radical and non-radical species are potential electron carriers between Fe and C. In all but major river systems, the freshwater/saltwater mixing that occurs in a shallow aquifer system, such as the one targeted in the project, dominates the chemistry of the terrestrial marine interface. The system is a model for the unique biogeochemical system created by the permeable sediments in marsh and tidal flat systems. Field work was conducted on coastal groundwater collected at the Baruch Institute and Spiekeroog Island, Germany. Peroxide analysis was complicated by interference from high levels of background Fe(II).
