Freshwater streams are disproportionately large producers of greenhouse gases. Identifying the factors controlling their greenhouse gas production is critical as stream function is increasingly altered by both changing rainfall patterns and human pollution. This project aims to resolve the factors controlling stream greenhouse gas production. It will apply an unprecedented combination of continuous stream function and intensive isotope measurements to perennially flowing and intermittent streams in disturbed and undisturbed landscapes. This project is significant because it will quantify the changing role of streams in greenhouse gas emissions. Outcomes will provide critical information for managing Australia’s freshwater resources.

淡水溪流不成比例地产生大量温室气体。确定控制其温室气体产生的因素至关重要，因为降雨模式的变化和人类污染日益改变了河流的功能。该项目旨在解决控制河流温室气体产生的因素。它将前所未有地结合连续流函数和密集的同位素测量，对受干扰和未受干扰景观中的永久流动和间歇溪流进行测量。这个项目意义重大，因为它将量化河流在温室气体排放中不断变化的作用。结果将为管理澳大利亚淡水资源提供关键信息。
