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.

该奖项资助了新的热电离质谱仪（TIMS）的收购，该奖项将集成到W.M.中。加利福尼亚大学圣克鲁斯分校的凯克同位素实验室。 TIMS将在最近翻新的气候控制实验室和湿化学实验室中共同置于地质样品进行同位素分析所需的清洁化学实验室。此开放用户设施的重新开放将催化新的研究，并提供培训本科，研究生和博士后研究人员使用高精度同位素方法论所需的工具。地球和行星科学系是该国最大的地球科学系之一，拥有超过150个专业的学生，​​他的人口代表该学生团体，其中包括代表不足的种族背景的40％以上的人，而第一年级的一年级班则占第一代大学生的41％。该奖项的外展活动包括一个可用于内部和外部用户的微型赠款计划，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系列地球学约会，该研究应用于大陆和海洋crust的起源和演变，射电系统的动力学以及辉煌和辉煌的速度和质量变化。其他功能包括对SR，CA，ND和PB同位素系统的测量，这些系统由UCSC Earth和海洋科学家应用，以响应于构造构造隆升，气候，生物地球化学循环和海洋循环的变化，以重建古 - 盐水的变化。 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络动力学和觅食生物的范围。
