This award funds the acquisition of a new Thermal Ionization Mass Spectrometer (TIMS) to be integrated into the W.M. Keck Isotope Laboratory at the University of California, Santa Cruz. The TIMS will be co-located within the recently renovated climate-controlled laboratory and wet chemistry clean labs needed for the preparation of geologic samples for isotopic analysis. The reopening of this open-user facility will catalyze new research and provide the tools needed to train undergraduate, graduate and postdoctoral researchers in the use of high precision isotopic methodologies. The Earth and Planetary Science department, which is one of the largest Earth Science department?s in the country with over a 150 majors, has a population representative of the student body which includes over 40% from underrepresented ethnic backgrounds and a first year class made up of 41% of first generation college students. Outreach from this award includes a mini-grants program, available to internal and external users, to support exploratory and developmental research.This facility will allow high precision U-Pb and U-series geochronologic dating with research applied to the origin and evolution of the continental and oceanic crust, the dynamics of volcanic systems and the timing and rate of glaciations and climatic change. Additional capabilities include measurements of the Sr, Ca, Nd, and Pb isotope systems, which are applied by UCSC Earth and Marine scientists to reconstruct variations in paleo-seawater in response to changes in tectonic uplift, climate, biogeochemical cycling and ocean circulation. UCSC paleontologists and ecologists use these same tools to study food web dynamics and foraging ranges of organisms in the present and past.

该奖项资助了一个新的热电离质谱仪（TIMS）的收购，将集成到W.M.位于圣克鲁斯的加州大学凯克同位素实验室。TIMS将设在最近翻修的气候控制实验室和湿化学清洁实验室内，这些实验室是制备同位素分析所需的地质样品所必需的。这一开放用户设施的重新开放将促进新的研究，并提供培训本科生、研究生和博士后研究人员使用高精度同位素方法所需的工具。地球与行星科学系是地球科学系中最大的系之一。在全国有超过150个专业，有一个人口代表的学生团体，其中包括超过40%的代表性不足的种族背景和第一年类由41%的第一代大学生。该奖项的推广活动包括一项小额赠款计划，供内部和外部用户使用，以支持探索性和发展性研究，该设施将允许高精度的U-Pb和U系列地质年代测定，研究应用于大陆和海洋地壳的起源和演变，火山系统的动力学以及冰川和气候变化的时间和速度。其他能力包括测量Sr，Ca，Nd和Pb同位素系统，UCSC地球和海洋科学家应用这些系统来重建古海水中的变化，以应对构造隆起，气候，地球化学循环和海洋环流的变化。UCSC古生物学家和生态学家使用这些相同的工具来研究食物网动态和过去和现在的生物觅食范围。
