Atlantic meridonal overturning circulation during interglacials (AMOCINT)

Marion Dufresne号考察船的Calypso取芯系统可利用的高沉积率间冰期断面取样调查和取芯地点。2.为有针对性的IODP钻探进行详细的现场调查，以在关键地点恢复过去间冰期的厚海洋沉积物剖面，以监测大西洋经向翻转环流（AMOC）的变化。3.根据现有的Calypso岩芯和AMOCINT内采集的新岩芯进行可行性研究：制作具有世纪尺度分辨率的北大西洋环流参数时间序列，反映过去80万年末次间冰期和以前的间冰期，并提供与南极洲和格陵兰冰芯记录的详细比较。

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.
