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

这项研究将描述流体组成和微生物群落结构，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。这套样品和数据的收集和分析将为(1)解决地幔变化和微生物功能(例如，AOM，H-氧化)的途径，(2)限制非生物和生物矿物的变化和变化机制，(3)描述这一自然发生的高碱性(pH 12.5)和富含硫化物的溶液中的微生物丰度、多样性、代谢率和生态作用，(4)进行培养丰富研究，以及(5)开始了解水文和泥石流系统如何响应构造作用力。通过研究生的参与。这项工作对更广泛的科学界也有很大的潜在好处，也有一个重要的不断发展的国际合作。

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 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.
