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.Broader impacts: The high resolution record of this area will serve as the marine type locality for a broad community of paleoceanographers and paleoclimatologists and thus serve an important need, a capability that is currently lacking.

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将共同创建热带古气候变异性的类型部分，并制作一套常见的古海洋学分析，特别是在无机指标方面。广泛的影响：该地区的高分辨率记录将作为广泛的古海洋学家和古气候学家社区的海洋类型地点，从而满足重要的需求，这是目前所缺乏的能力。
