0343017CrissThis grant provides partial support for the acquisition of automated headspace equilibration device for stable isotopic analysis of H and O in natural water samples. The device would be mated to an existing stable isotope mass spectrometer (Finnigan MAT 252) in the Department of Earth & Planetary Sciences at Washington University - St Louis (Wash-SL). The upgrade of this facility will support NSF/EAR funded research that relies on stable isotopic data to study the residence time and base flow of economically important major rivers in the central U.S. from storm to drought conditions (e.g., the Mississippi and the Missouri) and study of the flow dynamics of karst systems in response to storm events. The upgraded SIRMS facility will also support student training in methods of stable isotopic analysis in the hydrologic as well as petrologic sciences.***

0343017Criss这笔赠款为购买自动顶空平衡装置提供部分支持，用于对天然水样中的H和O进行稳定同位素分析。 该设备将与华盛顿大学圣路易斯分校 (Wash-SL) 地球与行星科学系现有的稳定同位素质谱仪 (Finnigan MAT 252) 配对。 该设施的升级将支持 NSF/EAR 资助的研究，该研究依靠稳定同位素数据来研究美国中部主要经济河流从风暴到干旱条件下的停留时间和基流（例如密西西比河和密苏里河），并研究岩溶系统响应风暴事件的流动动力学。 升级后的 SIRMS 设施还将支持学生进行水文和岩石科学稳定同位素分析方法的培训。***
