Carbon Dioxide and Carbon Isotopes in the Taylor Dome and Vostok Ice Cores

该奖项是为了支持一个项目，该项目利用泰勒圆顶和沃斯托克冰芯的冰，重建了几个时期的大气二氧化碳（以及二氧化碳的碳-13同位素）记录，包括末次冰期-全新世过渡、间冰期、全新世中期、最近1000年和倒数第二个冰期。本研究的主要目的是研究末次冰消期冰芯中温室气体的变化与温度变化（由氧和氘同位素表示）之间的相位关系。此外，将在这些岩心中测定过去1000年和全新世中期的大气二氧化碳浓度。

This award is for support of a program to reconstruct the record of atmospheric carbon dioxide (and the carbon-13 isotopes of carbon dioxide) over several intervals, including the Last Glacial Maximum-Holocene transition, interstadial episodes, the mid-Holocene, the last 1000 years and the penultimate glacial period, using ice from the Taylor Dome and Vostok ice cores. The major objective of this study is to investigate the phase relationship between variations of the greenhouse gases occluded in the ice cores and temperature changes (indicated by oxygen and deuterium isotopes) during the last deglaciation. In addition, the concentration of atmospheric carbon dioxide over the past 1000 years and during the mid-Holocene will be determined in these cores.
