Nutrient export fluxes in coastal systems, primarily as nitrogen (N), phosphorus (P) and silicon (Si), have a significant impact on water quality and control the nature and magnitude of coastal productivity. In coastal areas, nutrients are delivered by rivers, groundwater discharge and atmospheric deposition. The growing impact of anthropogenic activities has profoundly affected the quality of marine waters over the last 50 years. Such alterations are well documented and have been linked to perturbations in nutrient export fluxes from the continent[1] . In areas of restricted water exchange, the export of excess N and P to coastal waters may cause coastal eutrophication, a blooming of suspended and bed-anchored algae (including toxic species), alteration of community structures, degradation in the ecosystem function and modifications of marine food webs[2] . The continuing changes in land use and global urbanisation of coastal margins[3] thus pose a continual threat to coastal waters.
