Physical and geochemical coupling in a subterranean estuary (2019-2023)

This project aims to determine and quantify key mechanisms governing chemical transport and transformation in a tidally dominated subterranean estuary. The study will be the first attempt worldwide to measure simultaneously the temporal and spatial variability of coupled physical and geochemical processes in the intertidal zone of a subterranean estuary. The research will generate much-needed understanding of the role of subterranean estuaries in controlling fluxes of land-derived chemicals to the ocean via submarine groundwater discharge. The outcomes will have important implications for assessing and minimising the impact of groundwater contamination on the coastal zone.
