Uncoupling past salinity and temperature signals in the Indo-Pacific Warm Pool: implications for climate change in the Australian region

热带海洋，特别是紧邻澳大利亚北部的印度洋-太平洋暖池，通过厄尔尼诺现象和相关现象，在调节全球和澳大利亚气候方面发挥了关键作用。使用一种新的微观分析方法分析深海岩心中的单个有孔虫，我们将重建暖池内过去的盐度和温度变率，并确定在不属于现代记录的气候条件下的降雨模式变化、ENSO和季风行为。这一信息对于了解过去的气候和预测未来与厄尔尼诺有关的澳大利亚干旱和潮湿循环的强度和频率至关重要。

The tropical oceans and in particular the Indo-Pacific Warm Pool, immediately to Australia's north, play a key role in modulating global and Australian climate through El-Niño and related phenomena. Using a new microanalysis approach to analyse individual foraminifera from deep-sea cores, we will reconstruct past salinity and temperature variability within the Warm Pool, and determine changing rainfall patterns and, ENSO and monsoon behaviour under climate conditions that lie outside modern records. This information is vital for understanding past climate and predicting the future intensity and frequency of El-Niño related drought and wet cycles in Australia.
