The objectives of this research are to reliably measure the direct fluxes of trace elements across the sediment-water interface of field-collected cores, measure temporal and spatial variability of such fluxes and determine the importance of Mn, Fe and S redox cycling on trace element production and consumption. This project will determine whether the recycling of metals within surficial sediments has an important impact on water column metal concentrations.
