We propose an alternative scheme for the use of 224Ra/228Th disequilibria to investigate carbon and nutrient export from a permeable sandy seabed. Sediment profiles of dissolved 224Ra, total 224Ra and 228Th were determined at two different intertidal sand systems - an intertidal sandy beach near Wei...
