Climatic Record of the North Atlantic

从北大西洋收集活塞和重力岩芯，以确定“海因里希”层的物质来源和寻找记录在冰芯中的气候事件的实地计划。海因里希层没有有孔化石贝壳，含有与下面的冰川沉积物不同的冰筏碎屑。就是这样，PI将使用颜色变化来识别回到站点609的同位素阶段5的数千年持续时间事件。在泥沙漂移的高沉积速率地区将获得新的岩心。AMS测年将提供年表。

A field program to collect piston and gravity cores form N. Atlantic to ascertain the source of material in "Heinrichs" layers and to search for climatic events recorded in ice cores. Heinrich layers are devoid of foraminaferal shells and contain different ice-rafted debris than underlying glacial sediments. Is this PIs will use color variations to identify millennia duration events back to isotopic stage 5 at Site 609. Fresh cores will be obtained in high sedimentation rate areas in sediment drifts. AMS dating will provide chronology.
