Resolving uncertainty over the importance of N-fixation versus denitrification in coastal systems. Nutrient enrichment of coastal waters is a significant national and international problem requiring urgent action. Despite many studies and many millions of dollars in research funding we know virtually nothing about the relative importance of the major nitrogen cycling pathways, N-fixation and denitrification. Many hundred's of millions of dollars are likely to be spent over the next ten years on the management of nitrogen enrichment of Australia's coastal waters. This study will use a new method for directly measuring N-fixation to resolve uncertainty over the importance of N-fixation versus denitrification in coastal systems; information which is critical for the efficient allocation of management resources.

解决沿海系统中固氮与反硝化作用重要性的不确定性。沿海沃茨的富营养化是一个重大的国家和国际问题，需要采取紧急行动。尽管有许多研究和数百万美元的研究经费，我们几乎不知道的主要氮循环途径，固氮和反硝化的相对重要性。在未来十年内，可能会花费数亿美元用于管理澳大利亚沿海沃茨的氮富集。本研究将使用一种新的方法，直接测量氮固定，以解决不确定性的重要性，氮固定与反硝化作用在沿海系统;信息，这是至关重要的管理资源的有效分配。
