This award supports the acquisition of a gas-source, isotope-ratio mass spectrometer to measure clumped isotopologues of CO2 (Δ47) at the University of Washington. The ability to make these measurements with high precision enables a wide range of applications?from constraining atmospheric CO2 budgets to documenting the thermal histories of meteorites?and the most developed application to date is a paleothermometer based on 13C-18O clumping in carbonates. Carbonate clumped isotope thermometry offers the promise of reconstructing terrestrial paleoclimate, paleoelevation, and the thermal history of the upper crust. Specific studies will include use of the mass spectrometer to (1) study carbonate formation processes in soils and develop paleoenvironmental proxies in paleosols, (2) constrain the climatic and topographic evolution of the Andes, Tibetan plateau, and western North America, and (3) investigate isotopic resetting in buried carbonates and fluid migration, mineral growth, and interactions of brittle deformation and diagenesis in sedimentary basins. The mass spectrometer will substantially enhance research infrastructure enabling a large number of investigators and students to advance core research supported by NSF-EAR. Research made possible by this facility will be integrated with education, outreach, and broadening participation efforts through university-level curriculum development and experiential learning opportunities for minority high school students and teachers. These activities will strengthen K-12 science education and partnerships between the university and high schools, helping to raise awareness of geoanalytical capabilities in the U.S. The PI is an early career investigator.

该奖项支持收购华盛顿大学二氧化碳（＆＃916; 47）的同位素比率质谱仪的收购。以高精度进行这些测量的能力可以实现广泛的应用？从约束大气二氧化碳预算到记录陨石的热历史？迄今为止，最发达的应用是基于碳酸盐中13c-18o结块的古热量计。碳酸盐团块的同位素温度计提供了重建陆地古气候，古硫化和上层外壳的热史的希望。 Specific studies will include use of the mass spectrometer to (1) study carbonate formation processes in soils and develop paleoenvironmental proxies in paleosols, (2) constrain the climatic and topographic evolution of the Andes, Tibetan plateau, and western North America, and (3) investigate isotopic resetting in buried carbonates and fluid migration, mineral growth, and interactions of brittle deformation and diagenesis in沉积盆地。质谱仪将大大增强研究基础设施，使大量研究人员和学生能够推进NSF-Ear支持的核心研究。该设施的研究将与教育，外展和扩大参与工作相结合，并通过大学级课程发展和少数民族学生和老师的体验学习机会。这些活动将加强大学和高中之间的K-12科学教育和伙伴关系，有助于提高对美国地理分析能力的认识。
