The hyper-accumulation of monosulfidic sediments has a directsocial, economic and environmental impact on communities in many parts of Australia, including highly valued wetland systems such as the Ramsar wetlands of the lower Murray Darling Basin and internationally recognised Peel-Harvey Estuary of WA. Maintenance dredging of these materials alone costs the nation millions of dollars annually. The hyper monosulfidic sediments are also linked to severe environmental impacts. This project will inform how these materials develop and accumulate. This new knowledge will be of immediate relevance for the management of eutrophic estuaries.

单硫化物沉积物的过度积累对澳大利亚许多地区的社区产生了直接的社会、经济和环境影响，包括高价值的湿地系统，如墨累达令盆地下游的拉姆萨尔湿地和国际公认的西澳皮尔-哈维河口。仅这些材料的维护疏浚每年就要花费国家数百万美元。高单硫化物沉积物也与严重的环境影响有关。这个项目将告诉我们这些材料是如何发展和积累的。这一新知识将与富营养化河口的管理直接相关。
