Sustainable water quality is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of Australia's lakes and estuaries, it is crucial to understand their ecological past and to determine their state prior to and post-European settlement. This project develops and applies novel methodologies to reconstruct the history of cyanobacterial blooms, eutrophication and anoxia in Australian waterways. It will help to identify human impact on water quality. The new methodologies, applied to ancient sedimentary rocks, will also yield information about the effect of environmental changes on early life on Earth, enforcing Australia's position in the study of global geochemical cycles.

对于澳大利亚的经济和社会发展，可持续水质是至关重要的问题。为了能够预测和计划澳大利亚湖泊和河口的未来，了解其生态过去并确定其在欧洲后定居点之前和确定其状态至关重要。该项目开发并应用了新的方法来重建澳大利亚水道中蓝细菌盛开，富营养化和缺氧的历史。这将有助于确定人类对水质的影响。应用于古代沉积岩的新方法还将产生有关环境变化对地球早期生命的影响的信息，从而在全球地球化学周期研究中执行澳大利亚的地位。
