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.

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，以创建在热带地区的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indicators.Broader方面的影响：该地区的高分辨率记录将作为一个广泛的古海洋学家和古气候学家社区的海洋类型的地方，从而服务于一个重要的需求，目前缺乏的能力。
