Oxygen Isotope Analysis of Ice Cores

氧同位素比值提供了关键的气候信息， 极地研究 这项技术的一个主要用途是在冰芯 研究储存的积水的同位素比率 提供气候和海拔特征 几个冰芯 目前正在进行或正在等待冰川学项目的分析。 为这些项目收集的大量样本将具有 进行O-18含量分析 这些分析将在 华盛顿大学第四纪同位素实验室， 在那里建造了一个氧同位素设施。 该设施包括一个自动化的Micromass 903光谱仪， 采用三重收集器同时测定13 C/12 C 和18-O/16-O比率。

Oxygen isotope ratios provide critical climatic information in polar research. A major use of this technique is in ice core research where the isotope ratios of the stored accumulated water provide climate and elevation signatures. Several ice cores will be obtained or are awaiting analysis of glaciological programs. A large number of samples collected for these projects will have to be analyzed for O-18 content. These analyses will be done at the Quaternary Isotope Laboratory of the University of Washington, where an oxygen isotope facility was constructed for this purpose. The facility contains an automated Micromass 903 spectrometer, with a triple collector for simultaneous determination of 13C/12C and 18-O/16-O ratios.
