C02/Air Ratios and 13CO2 in Ice Cores

这个奖项支持了第二次格陵兰冰盖的一个方面 项目（GISP II）。 来自格陵兰Summit的GISP核心将 提供非常古老的冰和古气候信息， 时间分辨率，由于普遍的积累率和平均值 全年气温 这一努力将在这一核心领域建立一个 高分辨率二氧化碳记录，这是必要的， 了解碳循环中的自然干扰， CO2与气候的关系和相互作用。 这 记录，当与温度记录比较时（以及 微粒/化学/宇宙成因同位素记录）将产生 关于CO2与气候的因果关系的信息， 以及大气中二氧化碳含量变化的机制 不同的时间尺度。 如果在过去的几年里 冰川可以被证实，重要的信息将是 根据人为改变的气候序列获得 地球的微量气体的关系

This award supports one aspect of the second Greenland Ice Sheet Project (GISP II). The GISP core from Summit, Greenland, will produce very old ice and paleoclimatic information with excellent time resolution, due to the prevailing accumulation rate and mean annual temperature. This effort will establish in this core a high resolution CO2 record, which is necessary to ultimately understand the natural disturbance in the carbon cycle, and the relationship and interaction between CO2 and climate. This record, when compared to temperature records (and particulate/chemistry/cosmogenic isotope records) will yield information on the cause/effect relationship of CO2 and climate, and on the mechanisms to produce atmospheric CO2 variations over different time scales. If the rapid variations in the last glacial could be confirmed, important information would be obtained on the climatic sequence of the anthropogenic alterations to the earth's trace gas involving in recent times.
