项目摘要

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-THOMPSON0820779这项MRI奖支持收购电感耦合扇区田间质谱仪（ICP-SFMS），以从冰芯中提取大气痕量元素历史并评估当代水质。获得该工具的知识分子和科学动机源于记录和了解当代和过去的地球系统变化的紧迫性。痕量要素是重建地球系统中过去过程的特殊工具，并且由于某些有毒物种是由人类活动产生的，用于监测全球人为的足迹。 ICP-SFM可以同时分析小型质量样本中的许多痕量和超轨道元素，并将允许从新的和存档的冰芯中提取新的代理信息。这些分析将使可以识别冰芯和其他水样中的杂质来源，从中可以得出有关过去大气环流模式，人为排放，外星贡献和火山循环模式的知识。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大教育和外展活动有关。学生将接受有关最先进的仪器的培训，以支持他们的研究生研究培训。
