9213907 Helgeson This award will support collaborative research between Harold Helgeson, University of California at Berkeley, and Mariano Valenza, University of Palermo, Italy. The proposed research is an effort to understand better the organobiogeochemisty of geothermal systems and the role that bacteria play in mediating the organic/inorganic interface in geochemical processes. The research will take place at the hot springs in the Aeolian Islands and at the Marcello Carapezza Geochemistry Laboratory on the island of Vulcano and the Istituto di Geochimica dei Fluidi in Palermo, Sicily. The project is an integrated study of the relation between the metabolism of thermobarophilic bacteria in hot springs, the organic/inorganic chemistry of the thermal waters and fumarolic gases, and the composition of the mineralogic environment through which they pass. The Italian research team has intimate familiarity with the geology of the region, together with expertise in sampling and monitoring, and will provide on-site laboratory facilities. The US group brings theoretical and laboratory skills, and familiarity with thermodynamic approaches to studying geothermal systems. ***

9213907 Helgeson 该奖项将支持Harold Helgeson，加州大学伯克利分校和Mariano Valenza，巴勒莫大学，意大利之间的合作研究。 拟议的研究是为了更好地了解地热系统的有机生物地球化学和细菌在介导地球化学过程中的有机/无机界面中发挥的作用。 这项研究将在伊奥利亚群岛的温泉、武尔卡诺岛的Marcello Carapezza地球化学实验室和西西里巴勒莫的Istituto di Geochimica dei Fluidi进行。 该项目是对温泉中嗜热菌的代谢、热沃茨和沼气的有机/无机化学以及它们所经过的矿物环境的组成之间的关系进行综合研究。 意大利研究小组非常熟悉该地区的地质情况，并具有取样和监测方面的专门知识，将提供现场实验室设施。 美国小组带来了理论和实验室技能，并熟悉热力学方法来研究地热系统。 ***
