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.

一项野外计划，以收集大西洋N. N. n. n. n. n. n。condece，以确定“海因里希”层中的材料来源，并搜索记录在冰芯中的气候事件。 海因里希层没有有孔虫壳，并且包含不同的冰碎片，而不是下层冰川沉积物。 是该PI将使用颜色变化来确定千年的持续时间事件回到609的同位素阶段5。 AMS约会将提供年表。
