Acquisition Gas Source Mass Spectrometer

项目摘要

This award is for the acquisition of a gas-source mass spectrometer for microbiological, biogeochemical and food web analysis. The mass spectrometer will be used to determine the stable carbon, nitrogen and sulfur ratios on bulk organic samples and individual molecules in a variety of research projects by ecologists, biogeochemists and geologists. The six University of Alabama faculty on this award collaborate widely on research areas including (1) energy flow in stream and wetland ecosystems, (2) coupled biochemical cycling and trophodynamics of mercury in southeastern riverine ecosystems, the Everglades and the METALLICUS lakes projects, (3) determination of biotic and abiotic transformations of priority pollutants in groundwater systems, (4) ecology of deep-water corals in the Gulf of Mexico and Atlantic Ocean, (5) subsurface in situ immobilization of uranium coupled to dissimilatory metal-reducing bacterial activity, and (6) biogeochemistry of Mars-like environments. This award will impact teaching and research of both undergraduate and graduate students. The mass spectrometer will be in the Aquatic Chemistry Laboratory (a research facility within the Center for Freshwater Studies) at the university. Minority participation will be ensured through the efforts of the University of Alabama faculty and through the continuation of a long-standing relationship with Stillman College (an historically black college in Tuscaloosa).

该奖项是为了获得用于微生物，生物化学和食物网分析的气体源质谱仪。质谱仪将用于确定生态学家、地球化学家和地质学家在各种研究项目中大量有机样品和单个分子的稳定碳、氮和硫比率。该奖项的六位亚拉巴马大学教师在研究领域进行了广泛合作，包括（1）溪流和湿地生态系统中的能量流动，（2）东南部河流生态系统中汞的耦合生物化学循环和营养动力学，大沼泽地和METALLICUS湖泊项目，（3）确定地下水系统中优先污染物的生物和非生物转化，（4）墨西哥湾和大西洋深水珊瑚的生态学，（5）与异化金属还原细菌活动相结合的地下原位铀固定化，以及（6）类火星环境的地球化学。该奖项将影响本科生和研究生的教学和研究。质谱仪将在该大学的水生化学实验室（淡水研究中心的一个研究设施）。将通过亚拉巴马大学教师的努力和通过继续与斯蒂尔曼学院（塔斯卡卢萨历史上的一所黑人学院）的长期关系，确保少数族裔的参与。
