Some lakes, such as the Coorong lakes in South Australia, naturally sequester carbon dioxide in magnesium carbonate minerals. These minerals, which form in association with microorganisms in lake water, represent the safest possible long-term traps for carbon dioxide pollution. This project aims to determine the essential geochemical constraints on formation of magnesium carbonate minerals in the Coorong lakes, which are unique natural laboratories for studying carbon dioxide sequestration. By delivering fundamental understanding of how microbial populations alter water chemistry for carbonate production, this project aims to inform the design of efficient and sustainable technologies for carbon dioxide sequestration that emulate natural processes in lakes.

一些湖泊，如南澳大利亚州的库龙湖，自然地将二氧化碳隔离在碳酸镁矿物中。这些矿物质与湖水中的微生物一起形成，是二氧化碳污染最安全的长期陷阱。该项目旨在确定库龙湖碳酸镁矿物形成的基本地球化学制约因素，库荣湖是研究二氧化碳封存的独特天然实验室。通过提供对微生物种群如何改变碳酸盐生产的水化学的基本了解，该项目旨在为模仿湖泊自然过程的高效和可持续的二氧化碳封存技术的设计提供信息。
