Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands

人类正在以惊人的速度改变全球氮（N）和磷（P）循环。氮和磷释放到环境中会导致富营养化，这是全球沿海生态系统面临的最大威胁之一。在全球范围内，几乎没有努力控制不断增加的N和P排放。受污染地下水的迁移是氮和磷进入沿海地区的主要来源，也是被忽视的富营养化驱动因素。然而，对影响地下水中N、P转化的过程的研究很少，忽略了碳酸盐砂系统，也忽略了地下水关键过渡带的过程。该项目将产生新的知识，帮助我们了解地下水在沿海富营养化中的作用。

Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N and P to the coastal zone and an overlooked driver of eutrophication. Yet, research into the processes that influence N and P transformation in groundwater are scarce, they neglect carbonate sand systems and have ignored the processes in key groundwater transition zones. This project will generate new knowledge that will help us understand the role that groundwater plays in coastal eutrophication.
