Fundamental understanding of the geochemistry of the ocean is required to advance basic knowledge of the world we live in, and to reconstruct aspects of our past climate from the composition of ocean sediments and fossils. This work requires sophisticated instrumentation in a modern laboratory. This award provides the funding for a group of researchers at Rutgers University to purchase a new mass spectrometer (ICP-MS) and an associated laser ablation (LA) sample introduction system, so that they can continue their ongoing research into trace elements in seawater and ocean sediments, and to expand their measurements in new research directions. Our society is urgently interested in the role of the ocean in governing earth's climate; the research of the Principle Investigators will contribute to the fundamental understanding of physical, chemical and biological processes in the ocean that drive the exchange of carbon dioxide with the atmosphere. The new instruments will also be integrated fully into undergraduate and graduate teaching and research: (1) A combined undergraduate/graduate class entitled "Inorganic Mass Spectrometry for Earth Sciences" will be taught focusing on ICP-MS theory and practice; (2) The new facility will offer challenging opportunities for undergraduate research supported by Rutgers' Aresty, RISE, and the NSF Research Experiences for Undergraduates summer programs. In addition, the researchers will work with the new NSF-funded center Advancing the Impact of Research on Society (ARIS) to develop learning opportunities emphasizing participation in science. This project will be modeled on the NSF-funded Rutgers Polar-Interdisciplinary Coordinated Education (ICE) program, that has been successfully implemented in twenty-one classrooms across the country. A new educator course is currently being piloted and will be expanded and offered to a new cohort of educators interested in using scientific data in their teaching. The Principle Investigators have an established reputation for research that expands the capabilities of this type of instrumentation, and have trained many students, including many women and under-represented minorities, who have used these skills to qualify successfully for academic positions once they leave Rutgers.This award will be used to purchase a high-resolution inductively coupled plasma mass spectrometer with a Laser Ablation sample introduction unit and standard autosampler and introduction systems. This instrumentation is crucial to the research of members of the Departments of Marine and Coastal Sciences, Earth and Planetary Sciences and Environmental Sciences at Rutgers-New Brunswick, as well as users from associated departments at Rutgers-Newark and elsewhere. The new ICP-MS will allow analysis of minute concentrations of trace elements in samples such as seawater, ocean particles, the tiny shells of marine organisms, and glacial ice. The LA will add new capability to the laboratory, and will allow tiny regions of solid samples, such as deep-sea coral skeletons, to be analyzed by vaporizing the solid and injecting the resulting condensed gasses directly into the MS, without the need to dissolve the sample in an acid solution. The current projects of the Principle Investigators include investigation of trace metal dynamics in the Arctic and Antarctic polar oceans, associated with the large field programs GEOTRACES and the Palmer Long Term Ecological Research, the development of geochemical methods to reconstruct past ocean chemistry from trace element concentrations in fossil deep-sea corals and the shells of fossil micro-organisms called foraminifera, and paleoceanographic reconstructions through the International Ocean Discovery Program (IODP). The researchers have been at the forefront of these fields for more than twenty years, and this award allows them to continue to innovate in these research areas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

需要对海洋地球化学有基本的了解，以增进对我们生活的世界的基本了解，并根据海洋沉积物和化石的组成重建我们过去气候的各个方面。 这项工作需要在现代化实验室中配备先进的仪器。 该奖项为罗格斯大学的一组研究人员提供资金，购买一台新的质谱仪 (ICP-MS) 和相关的激光烧蚀 (LA) 样品引入系统，以便他们能够继续对海水和水中的微量元素进行持续的研究。海洋沉积物，并将其测量扩展到新的研究方向。我们的社会迫切关注海洋在控制地球气候方面的作用；原理研究人员的研究将有助于对海洋中驱动二氧化碳与大气交换的物理、化学和生物过程的基本理解。 新仪器也将全面融入本科生和研究生的教学和研究中：（1）本科生/研究生联合课程“地球科学无机质谱”课程将重点讲授ICP-MS理论与实践； (2) 新设施将为罗格斯大学 Aresty、RISE 和 NSF 本科生研究体验暑期项目的支持，为本科生研究提供具有挑战性的机会。此外，研究人员还将与 NSF 资助的新中心“促进研究对社会的影响”(ARIS) 合作，开发强调参与科学的学习机会。该项目将以 NSF 资助的罗格斯大学极地跨学科协调教育 (ICE) 计划为蓝本，该计划已在全国 21 个教室成功实施。目前正在试行一门新的教育工作者课程，并将对其进行扩展并提供给对在教学中使用科学数据感兴趣的新一批教育工作者。首席研究员在扩展此类仪器功能的研究方面享有盛誉，并培训了许多学生，其中包括许多女性和代表性不足的少数族裔，他们在离开罗格斯大学后利用这些技能成功获得了学术职位的资格。该奖项将用于购买一台高分辨率电感耦合等离子体质谱仪，配有激光烧蚀样品引入装置以及标准自动进样器和引入系统。 该仪器对于罗格斯大学新不伦瑞克分校海洋和沿海科学系、地球与行星科学系和环境科学系的成员以及罗格斯大学纽瓦克分校和其他地方相关部门的用户的研究至关重要。新的 ICP-MS 将能够分析海水、海洋颗粒、海洋生物的微小贝壳和冰川等样品中微量元素的浓度。 LA 将为实验室增加新的功能，并允许通过蒸发固体并将产生的冷凝气体直接注入 MS 来分析固体样品的微小区域，例如深海珊瑚骨骼，而无需溶解将样品置于酸性溶液中。 原则研究员当前的项目包括与大型实地项目 GEOTRACES 和帕尔默长期生态研究相关的北极和南极极地海洋中痕量金属动力学的调查，开发地球化学方法以根据痕量元素浓度重建过去的海洋化学深海珊瑚化石和有孔虫化石微生物的壳，以及通过国际海洋发现计划 (IODP) 进行的古海洋学重建。研究人员二十多年来一直处于这些领域的最前沿，该奖项使他们能够在这些研究领域不断创新。该奖项反映了 NSF 的法定使命，并通过利用基金会的智力优势进行评估，认为值得支持以及更广泛的影响审查标准。
