EAR-0233712PlankThis project supports a new technical position for the multi-user laser ablation and inductively coupled plasma laboratories in the Department of Earth Sciences at Boston University. These laboratories include a Merchantek 213 nm laser ablation microprobe, a VG PlasmaQuad ExCell ICP-MS, and a JY Ultima C ICP-ES. The facilities are the backbone of geochemical research in the Department of Earth Sciences, supporting the PIs' active research in subduction cycling, melt inclusions, marine biogeochemistry, marine export production proxies, ultra-high resolution paleoceanography, and silicate weathering. With over 75 different users during the past 2.5 years, the ICP laboratories also draw a large external userbase. In fact, 60% of the userbase is external to Boston University, and involves a wide range of predominantly NSF-funded research projects. Most of the applications involve high-precision, multi-element analysis of marine sediments and water column particulate matter, igneous rocks, volcanic glass, phenocrysts, and experimental run products. New directions include monazite and zircon geochronology, and trace element behavior in the weathering environment. The ICP facilities have a strong record of student involvement, with over 40% of the userbase being students (including 14 undergraduates). An important activity is the training of over 20 graduate students (12 internal, 11 external) as the next generation of analytical geochemists. ***

EAR-0233712Plank该项目支持波士顿大学地球科学系的多用户激光烧蚀和感应耦合等离子体实验室的新技术地位。 这些实验室包括 Merchantek 213 nm 激光烧蚀微探针、VG PlasmaQuad ExCell ICP-MS 和 JY Ultima C ICP-ES。 这些设施是地球科学系地球化学研究的支柱，支持 PI 在俯冲循环、熔融包裹体、海洋生物地球化学、海洋出口生产代理、超高分辨率古海洋学和硅酸盐风化方面的积极研究。 ICP 实验室在过去 2.5 年里拥有超过 75 个不同的用户，还吸引了大量的外部用户群。 事实上，60% 的用户群来自波士顿大学外部，并且涉及广泛的主要由 NSF 资助的研究项目。大多数应用涉及海洋沉积物和水柱颗粒物、火成岩、火山玻璃、斑晶和实验运行产品的高精度、多元素分析。 新方向包括独居石和锆石地质年代学，以及风化环境中的微量元素行为。 ICP 设施拥有良好的学生参与记录，超过 40% 的用户群是学生（包括 14 名本科生）。 一项重要活动是培训 20 多名研究生（12 名内部研究生，11 名外部研究生）作为下一代分析地球化学家。 ***
