Maximum depths of detection of oceanic layers with enhanced transparency have been analyzed. The method is based on the estimation of the depth for which the signal-to-noise ratio is equal to the threshold level of a photoelectric recording system. The mathematical relations derived by A.P. Ivanov [Izv. Ross. Akad. Nauk, Fiz. Atmos. Okeana 32, No. 4, 514-522 (1996)] in the diffusion and small-angle diffusion approximations of the radiative transfer theory have been used. The method takes into account the optical properties of the water column and of the detected layer, the parameters of the transceiving system, and external illumination. Among the regularities considered, the conditions are revealed under which the maximum detection depth does not depend on the energetic characteristics of a light source and receiver, duration of light pulses, noise of transceiving channel, and external illumination.
