Investigating the synchroneity of global atmospheric shifts in the Holocene

南纬西风主导着今天南半球(包括澳大拉西亚地区)的气候变化，并与南大洋紧密耦合，调节着海气二氧化碳通量。然而，南方短暂的仪器记录使未来的气候预测变得不确定。该项目将首次非常详细地重建南大洋目标岛屿在关键变化时期的西风气流，代表了全新世(过去11,650年)的一系列气候状态。密集的放射性碳测年将允许与古气候记录网络精确对准，以测试整个澳大利亚和全球环流变化的时间、驱动因素和影响。

The austral mid-latitude westerly winds dominate Southern Hemisphere climate variability today (including the Australasian region) and are tightly coupled to the Southern Ocean, modulating the air-sea CO2 flux. However, short instrumental records in the south make future climate projections uncertain. This Project will develop the first highly-detailed reconstructions of westerly airflow from targeted Southern Ocean islands during key periods of change, representing a range of climate states over the Holocene (the last 11,650 yrs). Intensive radiocarbon dating will allow precise alignment to a network of palaeoclimate records to test the timing, drivers and impacts of circulation change across Australia and globally.
