This award enables the research team to continue their work on the ICECAP (ICE age Chemistry and Proxies) modeling project whose aim is to explore the utility of delta O-17 isotopes in ice core sulfate as a proxy for past oxidant levels. Generally, the research will investigate the evolution of the atmosphere's oxidation capacity during the Last Glacial Maximum and pre-industrial Holocene through to the present-day. Specifically, the researchers aim to evaluate the relative roles of emissions and atmospheric dynamics in the variability of oxidants on glacial-interglacial timescales as well as any regional variation in sulfate and nitrate isotopes.The award will support two graduate students and a high school science teacher. Successful completion of the work would improve the understanding of feedbacks between climate and the sources and sinks of methane, which would help improve our understanding of climate.

该奖项使研究团队能够继续他们在ICECAP（ICE年龄化学和代理）建模项目上的工作，该项目的目的是探索冰核硫酸盐中δ O-17同位素的效用，作为过去氧化剂水平的代理。 一般来说，这项研究将调查大气的氧化能力的演变，在末次冰期最大和前工业全新世通过到现在。 具体来说，研究人员的目标是评估排放和大气动力学在冰川-间冰期时间尺度上氧化剂变异性中的相对作用，以及硫酸盐和硝酸盐同位素的任何区域变化。该奖项将支持两名研究生和一名高中科学教师。 这项工作的成功完成将增进对气候与甲烷源和汇之间的反馈的理解，这将有助于增进我们对气候的理解。
