Acquisition of a Mass Spectrometry Facility for Global Change Research

9413957威廉姆斯该合同提供部分资金，用于购买将在南卡罗来纳大学地质科学系安装和运行的同位素比质谱仪和电感耦合等离子质谱仪。南卡罗来纳大学承诺提供购置设备所需的剩余资金。首席调查员和一大批多学科同事需要这些仪器的分析能力(光稳定元素的准确同位素比率和对地质样品的快速多元素分析)，以便在全球变化领域开展大量研究项目，包括研究古代海洋和湖泊过去的温度变化、大气中二氧化碳的地质史、海洋中的地球化学循环以及海洋和淡水盆地中非碳酸盐沉积物的年代学。***

9413957 Williams This award provides partial funding for the acquisition of an isotope ratio mass spectrometer and an inductively- coupled plasma mass spectrometer to be installed and operated in the Department of Geological Sciences at the University of South Carolina. The University of South Carolina is committed to providing the remaining funds necessary for the acquisition of the equipment. The Principal Investigator and a large multi-disciplinary group of colleagues require the analytical capabilities (accurate isotope ratios for light stable elements, and rapid multielement analysis of geological samples) of these instruments to carry out a significant number of research projects in the area of Global Change, including research on past temperature variations in ancient oceans and lakes, the geologic history of CO2 in the atmosphere, geochemical cycles in the oceans, and the chronology of non-carbonate sediments in marine and fresh-water basins. ***
