The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of recently discovered ancient corals in Indonesia using state-of-the-art microanalytical techniques. Outcomes from these palaeoclimate records will advance our understanding of global climate change, rainfall variability related to the El Nino - Indian Ocean Dipole system, and Australian drought.

印度尼西亚周围的海洋是地球上最温暖的海洋，也是全球大气环流的主要能源。 了解暖池在未来气候变化中的作用至关重要，但极具争议，因为其变化的潜在程度在很大程度上是未知的。 为了解决这个问题，该项目将利用最先进的微分析技术，对印度尼西亚最近发现的古珊瑚进行首次重大的地球化学调查。 这些古气候记录的结果将促进我们对全球气候变化、与厄尔尼诺-印度洋偶极子系统相关的降雨变率和澳大利亚干旱的理解。
