存在于海洋中的气泡羽状流既与海底水合物相关,又影响着海洋环境和大气环境,因此,本文针对羽状流的识别及与资源环境的相关性进行了系统的分析和总结.首先简要给出羽状流的产生机理,即大量天然气的海底渗漏.然后总结了羽状流的三种识别手段,即真实直观的摄影成像、成像清晰的声呐系统和探测面积大的地震方法.探讨了羽状流与水合物及冷泉的相关性:水合物赋存区域未必一定会有羽状流,有气体泄漏或羽状流区域未必一定存在水合物;冷泉发育区常见羽状流.最后分析了羽状流对海洋环境和大气环境的影响.以上结论和认识可为羽状流的深入研究奠定基础.
The bubble plume existing in the ocean is not only related to the seafloor hydrate, but also affects the marine environment and the atmospheric environment.Therefore, this paper systematically analyzes and summarizes the identification of the plume and the correlation with resources and environment.First, The mechanism of plume flow is briefly described, that is, the seabed seepage of a large amount of natural gas, and then the three identification methods of plume flow are summarized, that is, the real and direct photographic imaging, the clear imaging sonar system and the seismic method with large area. The correlation between the plume and the hydrate and the cold spring: the hydrate occurrence area may not necessarily have a plume, gas leakage or plume flow area does not necessarily exist hydrate; cold spring development zone common plume flow. The influence of plume on the marine environment and the atmospheric environment.The above conclusion and understanding can lay the foundation for further research on plume flow.
