This proposal requests support for research designed (1) to develop an accurate chronology for the climatic records contained in the Vostok East Antarctic ice-core, including the carbon dioxide record soon to be published by C. Lorius and his colleagues; and (2) to compare the Vostok records with climate records obtained from deep-sea cores. The work will be carried out in close cooperation with Claude Lorius and his colleagues at Grenoble. Given an accurate chronology, the length and quality of the Vostok record provide an unprecedented opportunity to understand the dynamics of processes which change carbon dioxide and climate. By cross-correlating the Vostok and deep-sea records, investigations proposed here will establish what the coherencies and phases are between: variations in the atmosphere at Vostok; variations in the temperature, circulation, and carbon budget of the ocean; and variations in volume of global ice. The proposed work promises to link the two most valuable records of climate change on orbital time scales (tens to hundreds of thousands of years) - ice cores and marine sediment cores. This temporal correlation will allow the PI to investigate the detailed nature of climate change in terms of atmospheric chemistry, oceanic circulation, and volume of continental ice. The Vostok ice core is of special importance because of its great length and excellent resolution.

该提案要求支持旨在（1） 为所含的气候记录编制准确的年表 在东方东南极冰芯，包括 二氧化碳记录即将由C. Lorius和他的 同事;（2）将东方号记录与气候进行比较 从深海岩芯中获得的记录。 这项工作将由 与克劳德·洛里厄斯及其同事密切合作， 格勒诺布尔 如果有准确的时间表， 东方号的记录提供了前所未有的机会， 了解改变二氧化碳的过程的动力学 和气候。 通过将东方号和深海 记录，这里提出的调查将确定 连贯性和阶段之间：大气的变化 在东方号上;温度、环流和碳的变化 海洋的预算;以及全球冰量的变化。 拟议中的工作承诺将两个最有价值的 轨道时间尺度上的气候变化记录（十至 数十万年）-冰芯和海洋沉积物 丹 这种时间相关性将允许PI 研究气候变化的详细性质， 大气化学，海洋环流，以及 大陆冰 东方号的冰芯具有特殊的重要性 因为它的长度和分辨率都很好。
