APPLICATION OF LADCP TO CO-RICH CRUSTS SURVEY

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.
