A theoretical study of the chlorophyll concentration and oceanic water on the Bit-Error-Rate (BER) and reliability of underwater optical communication (UWOC) has been performed. On the basis of generalized Collins formula, an analytical propagation expression for the intensity distribution of Gaussian beam through ocean is derived while considering environmental influences on it. Some analytical calculations are illustrated relating to the sea water transmission along the optical path through oceanic turbulence. By considering the effects of Caspian Sea water due to absorption and scattering through a year time duration in 2011, the values of received power, Signal to Noise Ratio (SNR) and BER are calculated. These results are illustrated by graphs and they are analyzed by detail. The results indicate the rule of chlorophyll concentration and beam divergence on reliability.
