This project aims to determine and quantify key mechanisms governing chemical transport and transformation in a tidally dominated subterranean estuary. The project 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 project 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. It will provide better understanding of the pathway of land-derived nutrients and contaminants entering coastal waters, leading to improvement of strategies for sustainable coastal resources management and development, and integration of upland and lowland catchments management.

该项目旨在确定和量化有关潮汐统治地下河口中化学运输和转化的关键机制。该项目将是全世界首次尝试简单地衡量地下河口潮间带耦合物理和地球化学过程的临时和空间变异性的尝试。该项目将对地下河口通过海底地下水排放来控制海洋中的陆地化学物质通量来产生急需的理解。结果将对评估和最大程度地减少地下水对沿海地区的影响具有重要意义。它将更好地了解进入沿海水域的土地衍生营养物质和污染物的途径，从而改善了可持续的沿海资源管理和发展战略，以及陆地和低地集水区管理的整合。
