Hemrich事件是末次和倒数第二次冰期中北大西洋强烈的冰山漂移时期，深海岩心中可以清楚地看到明显的冰携碎屑层。该事件以北大西洋东部海山中滴石层的发现者命名（Heinrich，1988），在北大西洋40°N以北的许多岩心位置都可分辨出Hein－rich层。跨越时间为＜2000a，多数为＜10
The Hemrich event was a period of intense ice drift in the mid-to-last and last-penultimate mid-Atlantic glaciers. Clear ice-bearing detrital layers were clearly visible in deep-sea cores. The event is named after the discoverer of stratum in seamounts in the eastern North Atlantic (Heinrich, 1988), and the Hein-rich layer is distinguishable in many core locations north of North Atlantic 40 ° N. Span time is <2000a and majority is <10
