Although many trace metals, such as zinc (Zn), act as vital nutrients for marine microorganisms, their oceanic biogeochemical cycles are poorly understood. In this research, chemists from Arizona State University and the University of Washington would use a suite of experimental, analytical, and computational research to quantitatively understand the fractionation of stable Zn isotopes that takes place on mineral surfaces in the ocean. Through advancing our understanding of the reactions involved in Zn isotope fractionation in the ocean, future scientists would be able to successfully apply isotopic zinc cycling to questions of greater oceanographic interest. In terms of broader impacts, this study would provide new insights into the biogeochemical cycling of the micronutrient zinc. One graduate student and one undergraduate student at Arizona State University would be supported and trained as part of this project.

虽然许多微量金属，如锌（Zn），是海洋微生物的重要营养物质，但人们对它们的海洋生物地球化学循环知之甚少。在这项研究中，来自亚利桑那州立大学和华盛顿大学的化学家将使用一套实验、分析和计算研究来定量地了解在海洋矿物表面发生的稳定锌同位素的分异。通过推进我们对海洋中锌同位素分馏反应的理解，未来的科学家将能够成功地将同位素锌循环应用于更大的海洋学兴趣问题。就更广泛的影响而言，该研究将为微量营养素锌的生物地球化学循环提供新的见解。作为该项目的一部分，亚利桑那州立大学的一名研究生和一名本科生将得到支持和培训。
