This project will determine the composition of Australian airborne dust and effects on the environment and in particular soils, rainforests and the marine realm, including reefs. 'Fingerprinting' the chemical and microbiological content of aeolian dust is of particular relevance to determining its impact on the health of the Australian people and environment. Atmospheric conditions propitious for dust entrainment and transport will be determined, and in particular atmospheric exchanges between Indonesia, southern Africa and Australia will be established. The relevance of aeolian dust to climate, ecosystems and biosecurity in our region will be established through the study of marine and lacustrine cores.

该项目将确定澳大利亚气载尘埃的成分及其对环境的影响，特别是对土壤、雨林和海洋领域，包括珊瑚礁的影响。“指纹”的化学和微生物含量的风沙是特别相关的，以确定其对澳大利亚人民的健康和环境的影响。将确定有利于尘埃夹带和输送的大气条件，特别是将建立印度尼西亚、南部非洲和澳大利亚之间的大气交换。将通过对海洋和湖泊岩芯的研究，确定风成尘与本区域气候、生态系统和生物安全的相关性。
