Collaborative Research: Establishment of a Climate Type-Section for the Tropical Atlantic from Cariaco Basin Sediments

0602392Peterson/Thunell/Lea/Black PI 将使用在卡里亚科盆地收集的两个新活塞核心的复合材料，生成上一个冰期-间冰期周期气候变化的高分辨率多代理低纬度沉积型剖面。目标是创建一个与高纬度冰芯（如 GISPS 和 Vostok）相对应的热带海洋。该方法遵循 NRC 的建议，即海洋界应在关键地点生成高质量记录。卡里亚科盆地是一个关键地点，这里很好地体现了ITCZ过去的变化。 来自四个机构的 PI 将共同努力创建热带古气候变化的类型部分，并进行一套常见的古海洋学分析，特别是在无机指标方面。

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.
