SGER: Kr-Ar-Xe Gravitational Separation Temperatures in GISP2 Ice: Correlations with Oxygen-18 and Borehole Measurements

Am-9812077克雷格，哈蒙大学，圣地亚哥标题：GISP2冰中的Kr-Ar-Xe重力分离温度：与氧-18和钻孔测量的相关性该SGER奖支持测量格陵兰岛GISP2冰芯中20个被困在冰中的气体的Kr/Ar和Xe/Ar比值。这种方法是从这些稀有气体相对于大气的重力富集度中得出古温度的。拟议的测量将验证从其他方法得出的古温度测量结果。该项目旨在开发、测试和应用这一新方法作为古温度分析的独立测试。该方法将把惰性气体方法扩展到覆盖整个冰川恢复范围(至110,000年)，并将Kr/Ar记录完成至40,000年。如果成功，这种方法应该会为在古气候推断和更安全的模型测试中的各种应用开辟道路。

Abstract ATM-9812077 Craig, Harmon University of California, San Diego Title: Kr-Ar-Xe Gravitational Separation Temperatures in GISP2 Ice: Correlations with Oxygen-18 and Borehole Measurements This SGER award supports the measurement of Kr/Ar and Xe/Ar ratios in 20 samples of gases trapped in ice from the GISP2 ice-core, Greenland. This method derives paleotemperature from the gravitational enrichment of these noble gas ratios relative to the atmosphere. The proposed measurements will validate paleotemperature measurements derived from other methods. The project is aimed at developing, testing, and applying this new approach as an independent test of paleotemperature analysis. The method will extend the noble gas method to cover the full range of ice recovery (to 110,000 years) and will complete the Kr/Ar record to 40,000 years. If successful, this method should open the way for a variety of applications in paleoclimate inference and more secure model testing.
