Mosley-Thompson0820779This MRI award supports the acquisition of an inductively coupled-sector field mass spectrometer (ICP-SFMS) to extract atmospheric trace element histories from ice cores and to assess contemporary water quality. The intellectual merit and the scientific motivation for acquiring this instrument arises from the urgency to document and understand both contemporary and past Earth system changes. Trace elements are exceptional tools for reconstructing past processes in the Earth?s system and as some toxic species are produced by human activities, for monitoring the global anthropogenic footprint. The ICP-SFMS allows simultaneous analysis of numerous trace and ultra-trace elements from small mass samples and will allow new proxy information to be extracted from both new and archived ice cores. The analyses will make it possible to identify sources of impurities in ice cores and other water samples from which knowledge about past atmospheric circulation patterns, anthropogenic emissions, extraterrestrial contributions and volcanic circulation patterns can be derived. The broader impacts of the work relate to the societal relevance of the science and the strong education and outreach activities of the principal investigators. Students will receive training on state-of-the-art instrumentation which will support their graduate research training.

Mosley-Gillpson 0820779该MRI奖项支持购买电感耦合扇形场质谱仪（ICP-SFMS），以从冰芯中提取大气痕量元素历史并评估当代水质。 获得这一仪器的知识价值和科学动机来自记录和了解当代和过去地球系统变化的紧迫性。 微量元素是重建地球过去过程的特殊工具？的系统和一些有毒物种是由人类活动产生的，用于监测全球人类足迹。 ICP-SFMS可以同时分析大量微量和超微量元素的小质量的样品，并将允许新的代理信息提取新的和存档的冰芯。 这些分析将有助于查明冰芯和其他水样中的杂质来源，从中可以了解过去的大气环流模式、人为排放、地球外贡献和火山环流模式。这项工作的更广泛影响与科学的社会相关性以及主要研究人员的强有力的教育和外联活动有关。 学生将接受国家的最先进的仪器，这将支持他们的研究生研究培训的培训。
