PI将继续研究北大西洋末次冰期冰筏碎屑(IRD)的地质来源,以推断哪些冰原经历了加速崩解,导致海因里希层沉积,作为向海洋注入淡水的记录。这些都对气候突变有影响。该研究将对北大西洋三个岩心的IRD单个颗粒进行Ar40/Ar39分析。这一多同位素和岩石学研究可以得出有关晚四世海洋-气候-冰盖相互作用和劳伦泰德冰盖区域动力学的重要结果。
英文摘要
The PI will continue her work on the geological provenance of ice-rafted detritus (IRD) in the North Atlantic during the last glaciation in order to infer which ice fields underwent accelerated calving leading to deposition of Heinrich layers as records of fresh-water injection in the ocean. These have implications for abrupt climate change. The study will involve Ar40/Ar39 analyses of individual grains of IRD from three cores in the North Atlantic. This multi-isotopic and petrological work could produce important results related to ocean-climate-ice sheet interactions in the late Quatenary and regional dynamics of the Laurentide ice sheet.
