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

这项研究将确定流体成分和微生物群落结构的特征，确定南查莫罗海山的化学和生物过程，并限制背景物理和水文地质条件。收集和分析这套样品和数据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速率和蚀变机制，（3）描述了这种天然存在的高碱性微生物丰度，多样性，代谢速率和生态作用（pH 12.5）和富含硫化物的溶液，（4）进行培养物富集研究，（5）开始了解水文和泥流系统对构造力的响应。更广泛的影响本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，而且国际合作也在不断增加。

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 ImpactsThe 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.
