This article examines the issue of transmitting a video data stream in real time. The aim of the work is to analyze the vertical profiles of phytoplankton and take into account their impact on energy budget of vertically oriented underwater wireless optical communication channel. As a result of the work, vertical profiles of total attenuation have been obtained for water with surface turbidity of 0.4 mg/m3 and 3 mg/m3. The magnitude of the attenuation at the depth with maximum concentration of phytoplankton differs by 6 times. Simulation has shown that when using NDB4116 laser LED with a radiation power of 100 mW as an optical transmitter, the depth at which the received power falls below maximum photodetector sensitivity ranges from 12 to 70 meters at given turbidity. At the same time, the use of PCM allows the transmission of a video data stream at a speed of 4 Mbit/s to the depth of 9 to 39 meters
