0602392Peterson/Thunell/Lea/BlackThe PIs will generate a high-resolution multi-proxy low-latitude sedimentary type section of climatic variability over the last glacial-interglacial cycle, using a composite of two new piston cores collected in Cariaco Basin. The objective is to create a tropical marine counterpart to high latitude ice cores such as GISPS and Vostok. The approach follows the recommendations of NRC that the marine community should produce high-quality records at key locations. Cariaco Basin is a key location, where the past changes in ITCZ are well represented. PIs from four institutions will work together to create the type-section of paleoclimate variability in the tropics and produce a suite of common paleoceanographic analyses, particularly in terms of inorganic indicators.

PIs将使用在Cariaco盆地收集的两个新活塞岩心的复合材料，生成最后一次冰期-间冰期旋回气候变化的高分辨率多代理低纬度沉积型剖面。其目标是创建一个与GISPS和Vostok等高纬度冰芯对应的热带海洋冰芯。该方法遵循了NRC的建议，即海洋群落应该在关键地点制作高质量的记录。卡里亚科盆地是一个关键的位置，它很好地代表了过去ITCZ的变化。来自四家机构的pi将合作创建热带地区古气候变化的类型剖面，并制作一套通用的古海洋学分析，特别是无机指标方面的分析。
