This project will analyze the petrology of ice-rafted detritus in high-sedimentation-rate cores from the North Atlantic, concentrating on the last glacial interval. Previous work has identified a persistent cycle of 1500 years at one site during both glacial and interglacial intervals, implying an inherent instability in the Earth's climate system resulting in varying production of icebergs. The project will expand the study to other sites, in order to determine the reliability of this finding.

该项目将分析来自北大西洋的高层岩心岩心中冰羊皮碎屑的岩石学，集中在最后的冰川间隔上。 在冰川间隔和冰川间间隔期间，以前的工作已经确定了一个地点的持续周期为1500年，这意味着地球气候系统的固有不稳定导致冰山的产生变化。 该项目将将研究扩展到其他站点，以确定该发现的可靠性。
