Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. 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.

利用高分辨率珊瑚古气候档案量化厄尔尼诺&#241；印度洋偶极子系统。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量来源。了解暖池在未来气候变化中的作用至关重要，但由于其变异性的潜在程度在很大程度上是未知的，因此争议很大。为了解决这个问题，该项目将使用最先进的微量分析技术，对最近在印度尼西亚发现的古珊瑚进行首次重大地球化学调查。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-印度洋偶极子系统有关的降雨变异以及澳大利亚干旱的理解。
