The Eemian interglacial serves as the most recent analogue for understanding the natural operation of the climate system during the current interglacial. The nature and pattern of the full deglaciation cycle and the return into a glaciated Earth are, however, poorly understood due to the inherent difficulties that arise in the comparison of palaeorecords from different natural archives that span this interval. Indeed, it seems that abrupt and rapid climatic oscillations characterised this period. Yet, due to the chronological problems, an understanding of the climatic dynamics and forcing mechanisms driving these rapid events is currently unattainable. This project will employ a powerful approach in which volcanic ash layers are used to synchronise and directly compare ice-core and marine sequences. A framework of volcanic events will be established from a new Greenland ice-core that will underpin chronological models and will enable an unprecedented insight into the differing response of the atmospheric and marine systems during rapid climatic events between 140,000-70,000 years BP.

EEMIAN冰川间是了解当前冰河期间气候系统自然运行的最新类似物。然而，由于比较来自此间隔的不同自然档案的古生物的固有困难，整个脱气周期的性质和模式以及回归冰川地球的回归众所周知。确实，似乎突然而快速的气候振荡是该时期的特征。然而，由于按时间顺序排列的问题，目前无法实现对气候动态和迫使推动这些快速事件的机制的理解。该项目将采用一种强大的方法，在该方法中，火山灰层用于同步并直接比较冰核和海洋序列。将从新的格陵兰冰核建立一个火山事件的框架，该冰核将支持按时间顺序排列的模型，并能够在140,000至70,000年之间快速的气候事件中对大气和海洋系统的不同反应进行前所未有的见解。
