The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling across a range of undisturbed to disturbed systems. It is intended that this project will provide information for conceptualising, calibrating and verifying models, including green-house gas production. Good models, and the data that support them, such as that provided by this study, are critical for the efficient allocation of management resources in Australian coastal systems, including by our partners. The findings from this project will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.

该项目的目的是了解和量化控制河口二氧化碳、甲烷和一氧化二氮排放的因素。沿海系统在全球温室气体排放中扮演着不成比例的大角色，但这一点的量化很差。该项目计划在一系列未受干扰到受干扰的系统中使用连续浓度和稳定同位素测量、过程测量和先进的数值模拟相结合的方法。该项目的目的是为概念化、校准和验证模型提供信息，包括温室气体生产。良好的模型和支持它们的数据，如本研究提供的数据，对于澳大利亚沿海系统的管理资源的有效分配至关重要，包括我们的合作伙伴。该项目的发现将对澳大利亚水道(包括生物多样性)的管理、修复和保护产生直接影响。
