EAR-0549641PlankThis project supports a 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. 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. An important activity is the training of graduate students as the next generation of analytical geochemists. ***

EAR-0549641PLANKTHIS项目支持波士顿大学地球科学系多用户激光消融和电感耦合等离子体实验室的技术立场。 这些实验室包括Merchantek 213 nm激光消融微型探针，VG Plasmaquad Excell ICP-MS和JY Ultima C ICP-ES。 该设施是地球科学系的地球化学研究的骨干，支持PIS在俯冲循环，融化包裹物，海洋生物地球化学，海洋出口生产代理，超高分辨率的古环摄影和硅酸盐风雨方面的积极研究。 ICP实验室还画了一个大型的外部用户群。 实际上，60％的用户群在波士顿大学外部，涉及多种由NSF资助的研究项目。大多数应用都涉及对海洋沉积物和水柱颗粒物，火成岩，火山玻璃，现场晶体和实验性运行产品的高精度，多元素分析。 新的方向包括在风化环境中的独居石和锆石的年代学以及痕量元素行为。 ICP设施的学生参与有很强的记录，超过40％的用户群是学生。 一个重要的活动是培训研究生作为下一代分析地球化学家。 ***
