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

0602392 Peterson/Thunell/莱亚/Black PI将使用在Cariaco盆地收集的两个新活塞岩心的合成物，生成上一次冰期-间冰期循环气候变化的高分辨率多代用品低纬度沉积类型剖面。其目的是建立一个热带海洋对应的高纬度冰芯，如GISPS和东方。该方法遵循了核管制委员会的建议，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PI将共同努力，创建热带地区古气候变化的典型部分，并产生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.
