EAR-0520648AnbarThis proposal will fund an ICP-MS technical specialist to support innovative research in the newly renovated and equipped W.M. Keck Foundation Laboratory for Environmental Biogeochemistry at Arizona State University (ASU). The goal of this laboratory is to promote research at the intersection of the geosciences, the life sciences and chemistry by capitalizing on recent advances in mass spectrometry. The new position will therefore support the development and application of novel analytical methods. A special focus of this position will be new types of isotopic analyses made possible by the development of multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS). Examples of planned work include: the use of Mo isotope measurements in ancient sediments to reconstruct changes in the amount of oxygen in the atmosphere and oceans; the measurement of Fe isotopes to better understand the environmental chemistry of this biologically essential element, and exploration of Cr isotopes to trace toxic pollutants. In addition to supporting specific research projects, this award will enhance the development of a vibrant new program in isotope biogeochemistry at ASU that brings together researchers in several departments, schools, centers and institutes spanning a number of disciplines. The award will make it possible for us to effectively fold our new instruments into integrative graduate and undergraduate training as part of this program. It will also enhance the ability of ASU faculty to mentor post-Ph.D., non-tenure-track staff scientists, several of whom are involved in the planned research efforts.

该提案将资助一名ICP-MS技术专家，以支持新装修和装备的W.M.的创新研究。亚利桑那州州立大学（ASU）凯克基金会环境生物地球化学实验室。该实验室的目标是通过利用质谱法的最新进展，促进地球科学、生命科学和化学交叉领域的研究。因此，新职位将支持开发和应用新的分析方法。 该职位的一个特别重点将是通过多接收器电感耦合等离子体质谱法（MC-ICP-MS）的发展而可能进行的新型同位素分析。计划开展的工作包括：在古代沉积物中使用钼同位素测量，以重建大气和海洋中氧气含量的变化;测量铁同位素，以更好地了解这一生物基本元素的环境化学;探索铬同位素，以追踪有毒污染物。除了支持具体的研究项目，该奖项将加强在亚利桑那州立大学同位素地球化学一个充满活力的新计划的发展，汇集了研究人员在几个部门，学校，中心和研究所跨越多个学科。该奖项将使我们有可能有效地折叠我们的新工具到综合研究生和本科生培训作为该计划的一部分。它还将提高亚利桑那州立大学教师指导博士后的能力，非终身教职的科学家，其中一些人参与了计划中的研究工作。
