Survey and core sites for sampling of high sedimentation rate interglacial sections available to the Calypso coring system of the RV Marion Dufresne. 2. Conduct detailed site surveys for targeted IODP drilling to recover thick marine sediment sections over past interglacials at key locations for monitoring Atlantic Meridional Overturning Circulation (AMOC) variability. 3. Provide a feasibility study based on already available Calypso Cores and new cores taken within AMOCINT: Produce time series of North Atlantic circulation parameters with century scale resolution for the last interglacial and previous interglacials over the past 800.000 years and provide detailed comparisons with ice core records from Antarctica and Greenland.

对马里昂·杜弗雷纳号房车的卡利普索取心系统可用的高沉积速率间冰期剖面进行调查和核心取样。2.进行详细的现场勘测，进行有针对性的IODP钻探，在关键地点恢复过去间冰期的厚厚海洋沉积物段，以监测大西洋子午线翻转环流的变异性。3.根据已有的卡利普索冰芯和在南极冰盖中心内采集的新冰芯进行可行性研究：制作过去800.000年来最后一次间冰期和以前的间冰期北大西洋环流参数的时间序列，并与南极洲和格陵兰岛的冰芯记录进行详细比较。
