Collaborative Research: Borehole Studies of ODP Site 1200, South Chamorro Seamount: A Window into Active Serpentinite Mud Volcanism

该研究将表征流体组成和微生物群落结构，定义南查莫罗海山的化学和生物过程，并约束背景物理和水文地质条件。样品和数据的收集和分析将为以下方面提供基础：(1)解决地幔蚀变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蚀变率和蚀变机制；(3)描述这种自然发生的高碱性（pH 12.5）和富硫化物溶液中的微生物丰度、多样性、代谢率和生态作用；(4)进行培养富集研究。(5)开始了解水文和泥石流系统如何响应构造强迫。更广泛的影响这个项目潜在的更广泛的影响包括通过研究生的参与将教育纳入研究。这项工作对更广泛的科学界也有重大的潜在好处，而且也有一个重要的日益增长的国际合作。

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.
