MRI: Acquisition of Finnigan MAT DELTA Plus Stable Isotope Ratio Mass Spectrometer With Gasbench II for Environmental Hydrological Study of Acid Mine Drainage & Watershed Dyna

0115884梅尔基奥尔这笔赠款通过主要研究仪器(MRI)计划提供部分支持，用于购买一台芬兰MAT DELTA PLUS稳定同位素比质谱仪和GasBitchII。这台设备将是我们环境、水文学和地球化学计划的关键部分，用于本科生研究和P.I.仪器研究。该仪器将安装在德波大学新装修的朱利安科学和数学大楼内，耗资3200万美元。所需设备将满足日益增长的学生对环境地球化学的兴趣，以及与印第安纳州自然资源部(IDNR)和印第安纳州地质调查局(IGS)正在进行的酸性矿山排水和盆地水文学的合作研究。P.I.、他的学生和同事还将利用光谱仪研究深盆地地下水和地层流体运移。正在进行的有大量学生参与的项目包括：印第安纳州酸性矿山排水场地污染物迁移研究(与IDNR和IGS合作)、Wolf-Red(威斯康星州)和Tippecanoe-Wabash(印第安纳州)流域地表水/地下水相互作用研究、印第安纳州南部裂隙-水流和岩溶环境中地下水系统的同位素研究、以及加利福尼亚州构造驱动的地层流体迁移研究。DePauw大学的教员将获得单独的资金，将大量利用该实验室研究河流沉积物运输和系统学，并参与印第安纳州河流观察计划。作为美国印第安人科学与工程学会(AISES)和奇卡诺人和美洲原住民科学促进会(SACNAS)的成员，P.I.坚定地致力于促进那些在地球科学中传统上代表性较低的群体的学生参与。这一承诺得到了DePauw大学的响应和支持，目前正在努力将环境稳定的同位素实验室与DePauw的妇女参与科学计划联系起来，并参与与美国土著部落学院一起评估威斯康星州红狼河流域的同位素水文学的项目。这个环境稳定的同位素设施将向内部以及外部学生和同事开放。*

0115884MelchiorreThis grant, made through the Major Research Instrumentation (MRI) Program, provides partial support to purchase a Finnigan MAT DELTAplus stable isotope ratio mass spectrometer with GasBench II. This equipment will be a key part of our Environmental, Hydrology, and Geochemistry program for both undergraduate research and the research of the P.I. Instrumentation will be housed within the newly renovated $32 million Julian Science and Mathematics Building at Depauw University. The requested equipment will serve growing student interest in environmental geochemistry as well as ongoing collaborative research on acid mine drainage and basin hydrology with the Indiana Department of Natural Resources (IDNR) and Indiana Geological Survey (IGS). The P.I., his students, and colleagues will also utilize the spectrometer for research on deep basin groundwater and formation fluid migration. Ongoing projects with significant student involvement includes studies of contaminant transport from acid mine drainage sites within Indiana (with IDNR and IGS), studies of surface water/groundwater interactions in the Wolf-Red (Wisconsin) and Tippecanoe-Wabash (Indiana) watersheds, isotopic studies of groundwater systems in fracture-flow and karst environments in southern Indiana, and studies of tectonic-driven formation fluid migration in California. Faculty at DePauw University with separate funding will make significant use of the laboratory to examine fluvial sediment transport and systematics and to participate in the Indiana Riverwatch Program. As a member of both the American Indian Science and Engineering Society (AISES) and the Society for Advancement of Chicanos and Native Americans in Science (SACNAS), the P.I. is firmly committed to promoting student participation for those groups traditionally underrepresented in the Earth Sciences. This commitment is echoed and supported by DePauw University, and efforts are underway to link the environmental stable isotope laboratory with DePauw's Women in Science Program and to participate in projects with Native American Tribal Colleges in evaluating the isotope hydrology of the Red-Wolf river basin of Wisconsin. This environmental stable isotope facility will be open to in house use as well as outside students and colleagues.***
