Abstract Growing interest in underwater communication is determined by the important role it has in exploring the aquatic and coastal regions, from surveillance to climate change monitoring. Due to the extremity of the environment, the implementation of underwater communication faces some serious challenges, such as attenuation, scattering, turbulence, etc. Several studies are dedicated to those issues. However, underwater bubbles as one form of turbulence attenuation have not been sufficiently explored, especially their effect on underwater optical communication (UWOC). In this paper, a new mathematical channel modeling technique for air bubbles is introduced using Beer-Lambert's attenuation law and geometrical optics to show the performance of optical communication based on distance, power, and water types. The simulation demonstrated that in a turbulent underwater environment infra-red channel presented a more robust performance compared to the visible light.
