Pleistocene Interaction Between the Atmosphere and Ocean in the Eastern Equatorial Pacific

大气环流的历史是一个重要的 古气候学的元素和最好的重建 通过分析风成沉积物， 在深海岩芯中发现的该提案要求支持使用 一系列新的活塞芯，以重建海洋的历史， 和赤道太平洋的大气环流。 的 本研究的科学目标是：1）重建历史 更新世北方半球信风的变化; 2） 确定气候变化与 赤道太平洋的生产力; 3）确定 轨道强迫和气候-海洋响应的性质 地区 这项研究很重要，因为它将提供 记录大气层对气候变化的反应， 气候强迫，记录海洋对 大气环流的变化，以及重要的数据基础， 测试大气环流模式的敏感性。

The history of atmospheric circulation is an important element of paleoclimatology and the best reconstructions of atmospheric circulation come from analyzing the aeolian sediments found in deep sea cores. This proposal requests support to use a series of new piston cores to reconstruct the history of oceanic and atmospheric circulation in the equatorial Pacific Ocean. The scientific goals of this study are to: 1) reconstruct the history of northern hemisphere trade winds for the Pleistocene; 2) determine the relationship between climate change and productivity in the equatorial Pacific; and 3) determine the nature of orbital forcing and climatic-oceanic response in this region. This research is important because it will provide documentation of the response of the atmosphere to changes in climatic forcing, documentation of the response of the oceans to changes in atmospheric circulation, and important data bases to test the sensitivity of atmospheric General Circulation Models.
