The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

该项目的目的是利用一些创新的实地和模拟方法确定沿海地区的氮去除途径。关于复杂的沿海景观如何控制最大化氮去除但最小化一氧化二氮（一种强效温室气体）排放的权衡，人们知之甚少。这项研究的结果将显着推进我们对沿海地区的区域和全球氮收支的理解。这将带来重大惠益，例如一个新的以科学为基础的定量框架，以促进最佳做法管理，减少陆地氮负荷和相关的下游影响，如富营养化，并减少一氧化二氮排放和相关的全球变暖。
