Advance Algorithms of Secchi depth Remote Sensing

As a new observation method, ocean remote sensing technology can obtain a large range of seawater transparency distribution characteristics in quasi real time. In recent years, ocean water color remote sensing technology has developed rapidly, especially the increasing number of water color remote sensing devices and the improvement of the accuracy of relevant algorithms, which make the remote sensing of sea water transparency get great development. This paper summarizes the research and development of ocean transparency remote sensing platform, analyzes several typical algorithms of sea water transparency remote sensing, and summarizes the current development status of sea water transparency remote sensing, so as to provide some theoretical reference for the research and further development of this field.
