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

PIS将利用在Cariaco盆地收集的两个新的活塞芯的组合，生成上一次冰川-间冰期旋回的高分辨率多代理低纬沉积类型的气候变异性剖面。其目标是创建一个热带海洋与高纬度冰芯的对应物，如GISPS和Vostok。这一做法遵循了NRC的建议，即海洋界应在关键地点制作高质量的记录。Cariaco盆地是一个关键位置，ITCZ过去的变化在这里得到了很好的体现。来自四个机构的PIS将共同努力，创建热带古气候变异性的类型部分，并编制一套共同的古海洋学分析，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.
