项目摘要
9321407 Wahlen This award is for support to investigate, in detail, the timing between changes in temperature (indicated by the isotopes of oxygen and hydrogen in the ice, as well as the accumulation rate) and atmospheric carbon dioxide (from measurements of occluded air) in the high resolution Greenland Ice Sheet Project Two (GISP2) ice core from central Greenland. The carbon dioxide measurements will be performed over periods of rapid climate change, such as the last glacial to interglacial transition and during the glacial interstadials, the Eemian and the previous glacial. The determination of leads or lags between temperature and atmospheric carbon dioxide will help to understand the interplay of carbon dioxide and climate. The carbon isotope composition of atmospheric carbon dioxide will also be analyzed for these periods in order to gain more information about the mechanisms and processes responsible for carbon dioxide and climate variations. ***
该奖项是为了支持在格陵兰中部的高分辨率格陵兰冰盖计划2 (GISP2)冰芯中详细研究温度变化(由冰中氧和氢的同位素以及积累率表明)和大气二氧化碳(来自遮挡空气的测量)之间的时间间隔。二氧化碳测量将在气候快速变化的时期进行,例如末次冰期到间冰期的过渡,以及在冰期间冰期、埃米间冰期和前一次冰期。确定温度和大气二氧化碳之间的领先或滞后关系将有助于了解二氧化碳和气候之间的相互作用。还将分析这些时期大气二氧化碳的碳同位素组成,以便获得有关二氧化碳和气候变化的机制和过程的更多信息。***
