Acquisition of A Gas Source Mass Spectrometer For Earth Sciences Research, University Of California, Berkeley

0112113 Ingram这笔NSF赠款为购买带有外围样品制备附件的气体源同位素比质谱仪提供部分支持，该仪器将安装在加州大学伯克利分校地球和行星科学系。该设备包括自动水和碳酸盐制备系统和元素分析仪。该仪器将主要由三位首席调查员B.Lynn Ingram、Michael Manga和Kurt Cuffey的研究小组使用。地球和行星科学部最近提供了新的升级空间，以容纳所需的设备。所要求的一揽子计划将极大地提高地球、行星科学和地理系以及加州大学伯克利分校的学生、博士后研究员和教职员工的研究能力。研究领域包括在利用河口、湿地、湖泊和沿海海洋沉积物和珊瑚重建古气候学和古环境中使用碳、氧和氢同位素(Ingram博士，地球和行星科学系)，在水文地质系统中使用氧和氢同位素作为示踪剂(地球和行星科学系Manga博士)，以及在冰川学研究中使用水和冰的氧和氢同位素比率(Cuffey博士，地理系)。地球和行星科学部拟议的质谱仪设施的其他用户包括James Kirchner博士(流域水文学和生物地球化学以及表面过程地貌学)、Walter Alvarez博士(小行星影响、地中海区域的构造、远洋石灰岩地层)、George BrimHall博士(矿产资源、低温地球化学、土壤地球化学)和William Berry博士(全球气候变化和古生代古地理、海洋学和生命变化)。地理系的另一位潜在用户是罗杰·伯恩(Roger Byrne)(历史生物地理学、加利福尼亚州和墨西哥的古环境以及花粉分析)。***

0112113IngramThis NSF grant provides partial support for the purchase of a gas source isotope ratio mass spectrometer with peripheral sample preparation attachments, to be housed in the Department of Earth and Planetary Sciences at the University of California, Berkeley. The equipment includes an automated water and carbonate preparation system and an elemental analyzer. The instrumentation will be primarily used by the research groups of the three Principal Investigators B. Lynn Ingram, Michael Manga, and Kurt Cuffey. The Department of Earth and Planetary Science has recently provided newly upgraded space to house the requested equipment. The requested package will greatly enhance the research capabilities of students, postdoctoral fellows, and faculty in the Departments of Earth and Planetary Science and Geography, and on the U.C. Berkeley campus in general. Research areas include the use of carbon, oxygen, and hydrogen isotopes in paleoclimatological and paleoenvironmental reconstructions using estuarine, wetland, lacustrine, and coastal marine sediments and corals (Dr. Ingram, Earth and Planetary Science Department), the use of oxygen and hydrogen isotopes as tracers in hydrogeologic systems (Dr. Manga, Department of Earth and Planetary Science), and the use of oxygen and deuterium isotopic ratios of water and ice in glaciologic research (Dr. Cuffey, Department of Geography). Other users of the proposed mass spectrometer facility from the Department of Earth and Planetary Science include James Kirchner (watershed hydrology and biogeochemistry, and surface process geomorphology), Walter Alvarez (asteroid impacts, tectonics of the Mediterranean region, stratigraphy of pelagic limestones), Dr. George Brimhall (mineral resources, low temperature geochemistry, soil geochemistry), and Dr. William Berry (global climate change and paleogeographic, oceanographic and life changes in the Paleozoic). Another potential user from the Department of Geography is Roger Byrne (historical biogeography, paleoenvironments of California and Mexico, and pollen analysis). ***
