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

该资助通过主要研究仪器（MRI）计划获得，为购买带有GasBench II的Finnigan MAT DELTAplus稳定同位素比质谱仪提供部分支持。该设备将成为环境、水文和地球化学项目的关键部分，用于本科生研究和P.I.研究。仪器将被安置在德堡大学新装修的耗资3200万美元的朱利安科学与数学大楼内。所要求的设备将满足学生对环境地球化学日益增长的兴趣，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的合作研究。私家侦探、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迁移。有大量学生参与的正在进行的项目包括研究印第安纳州酸性矿井排水地点的污染物运输（与IDNR和IGS），研究沃尔夫-雷德（威斯康星州）和蒂珀卡诺-沃巴什（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缝流动和喀斯特环境中地下水系统的同位素研究，以及研究加利福尼亚构造驱动的地层流体迁移。迪堡大学的教师将获得单独的资金，充分利用该实验室来研究河流沉积物的运输和系统，并参与印第安纳河观察计划。作为美国印第安人科学与工程学会（AISES）和奇卡诺人与美国原住民科学促进会（SACNAS）的成员，P.I.坚定地致力于促进学生参与那些传统上在地球科学领域代表性不足的群体。这一承诺得到了德堡大学的响应和支持，并正在努力将环境稳定同位素实验室与德堡大学的女性参与科学计划联系起来，并与美国原住民部落学院一起参与评估威斯康星州红狼河流域同位素水文学的项目。这个环境稳定同位素设施将开放给内部以及外部的学生和同事使用

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.***
