【摘要】：海底冷泉泄漏是全球碳循环过程中重要的一环,该系统分布的广泛性、机制的复杂性、与水合物资源的关联性及相关科学问题的重要性,使之成为海洋科学调查和研究的前沿领域.本研究评述了冷泉泄漏活动涉及到的几个碳循环问题,包括作为甲烷厌氧氧化反应(AOM)产物的碳酸盐在碳循环中的地位、大陆坡深源碳在冷泉泄漏中的贡献以及冷泉泄漏与金属矿产资源的关系等,藉此加深人们对该系统的理解.同时,本研究还介绍了在当前关于碳循环研究过程中,对海底冷泉探测常用的几种重要方法,包括以多波束探测气泡羽流,以坐底式探测器对冷泉泄漏活动进行原位、实时、持续地观测以及一系列近期开展的海底观测网计划.最后讨论了该领域未来发展的趋势及相关的重点问题,以期给相关研究提供一些有益的参考.
[Abstract]:The submarine cold spring leakage is an important part of the global carbon cycle process. The distribution of the system, the complexity of the mechanism, the relevance to hydrate resources and the importance of related scientific problems are important. Make it the frontier of marine scientific research and research. This study reviews several carbon cycle issues involved in cold spring leakage, including the status of carbonates in the carbon cycle as (AOM) products from anaerobic methane oxidation. The contribution of deep carbon source on the continental slope to the cold spring leakage and the relationship between the cold spring leakage and metal mineral resources are discussed in order to deepen the understanding of the system. At the same time, this study also introduces several important methods commonly used in the current research on the carbon cycle, including the detection of bubble plume with multi-beam, the in-situ and real-time detection of cold spring leakage with bottom detector. Continuous Earth observation and a series of recent undersea observation network programs. Finally, the trend of future development in this field and some key issues are discussed in order to provide some useful reference for related research.
