Coastal permeable (sandy) sediments are understood to be important bioreactors in the coastal and are of increasing interest to the coastal biogeochemistry community with important implications for nearshore ecology and water quality. Porewater collection and measurement techniques suitable for permeable sediments are relatively well developed whereas techniques for measuring chemical exchange (fluxes) across the sediment-water interface are currently limited, primarily because the techniques developed for fine-grained sediments cannot be used. EFDLab has participated in research in collaboration with researchers at the University of Hawaii, focused on developing methodology for measurement of transport of solutes into and out of permeable sediments.
