Climatic Record of the North Atlantic

一个现场程序，以收集活塞和重力岩心从N。 大西洋确定“海因里希斯”层中物质的来源 并寻找记录在冰芯中的气候事件。 海因里希 层没有有孔虫壳，并含有不同的 冰筏碎片比下面的冰川沉积物。 这是私家侦探吗 将使用颜色变化来识别千年持续时间的事件 回到609号地点的同位素第五阶段 将获得新鲜岩心 在高沉积率地区的沉积物漂移。 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.
