This study will characterize fluid composition and microbial community structure, define chemical and biological processes at South Chamorro Seamount, and constrain background physical and hydrogeologic conditions. Collection and analysis of the suite of samples and data will provide the foundation to (1) address pathways for mantle alteration and microbial functioning (e.g., AOM, H - oxidation), (2) constrain rates of abiotic and biotic mineral alteration and alteration mechanisms, (3) describe microbial abundance, diversity, metabolic rate, and ecological roles in this naturally occurring highly alkaline (pH 12.5) and sulfide-rich solution, (4) conduct culture enrichment studies, and (5) begin to understand how the hydrologic and mud flow systems respond to tectonic forcing. Broader Impacts The potential broader impacts of this project include incorporation of education in research, through the involvement of graduate students. There is also a significant potential benefit to the broader scientific community in this work, and there is an important growing international collaboration as well.

这项研究将表征流体组成和微生物群落结构，定义南chamorro海山的化学和生物过程，并限制背景物理和水文地质条件。样品和数据套件的收集和分析将为（1）解决地幔变化和微生物功能的途径（例如AOM，H-氧化），（2）限制非生物和生物矿物质变化和变化机制的限制，（3）（3）描述了微生物的丰富性，多样性，代理率和生态学上的8个自然率（3）。富含硫化物的溶液（4）进行培养富集研究，（5）开始了解水文和泥流系统如何对构造强迫做出反应。更广泛的影响该项目的潜在广泛影响包括通过研究生参与将教育纳入研究。在这项工作中，更广泛的科学界也有很大的潜在好处，并且也有一个重要的国际合作。
