LADCP在富钴结壳调查中的应用

APPLICATION OF LADCP TO CO-RICH CRUSTS SURVEY

简单介绍了LADCP设备的组成及工作方法,阐述了基于LDEO软件包进行数据后处理及质量控制的关键步骤。通过对在太平洋某海山测得的海流剖面资料进行处理分析,简要说明LADCP在富钴结壳调查中的应用。目前海山区的底流资料仍很匮乏,底流情况对富钴结壳成矿因素的影响研究有待进一步开展。在深水大洋较深水层中声学反射体数量较少,单个LADCP换能器的有效量程减小,LADCP的观测效果受到明显影响,使用双LADCP系统可大大增加其有效量程。

The components and the working principles of the LADCP are introduced in this paper. Discussed are also the key steps of data post-processing and quality control based on the LDEO software package. Through the processing and analysis of the current data of the seamount in the Pacific Ocean, the application of LADCP to Co-rich crusts survey is illustrated briefly. The current data of the bottom water are very rare now. The measurement range of the single-LADCP transducer decreases because of the few scatters in the deep ocean. The LADCP measurement is affected significantly. However, the measurement range of the transducer can increase obviously when double-LADCP system is used.
