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.

0602392Peterson/Thunell/Lea/BlackPI 将使用在卡里亚科盆地收集的两个新活塞岩心的复合材料，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率的类型部分，并进行一套常见的古海洋学分析，特别是在无机指标方面。 更广泛的影响：该地区的高分辨率记录将作为海洋为广大古海洋学家和古气候学家群体提供了典型的地点，从而满足了重要的需求，而这种能力是目前所缺乏的。
