Design and Analysis of Variation in Chlorophyll and Depth for Open Ocean Underwater Optical Communication

The underwate communication is of great interest of research for many researchers because of increased dealings of human beings with world exists underwater. Underwater Commucation Technology (UCT) is becoming an important part of communication technologies. These include communication between divers, ships, and network system for autonomous underwater vehicles. However, optical communication with underwater exchange of information is challenged with many issues. In this paper, the attenuation for optical transmission is obervsed for optical waves that are absorbing inside water, in result, suspending particles and planktons produces optical scattering indirectly. In connection, underwater needs to rectify high attenuation regions for analysing ocean composition affects in Deep Ocean. This produces chlorophyll profiles that identify the attenuation in underwater communication.with high attenuation. In past studies, the constant attenuation is observed irrespective of depth of occean. Furthemore, the paper address, optical attenuation for underwater communication via depth dependent. The system is tested for 400–700 nm and 0–250 m depth for chlorophyll concentration profile (S1–S9). The system is demonstrated via GUI developed in Matlab that shows the optical attenuation at different depths underwater and along with that regions with deep chlorophyll maximum (DCM) are also shown.
