Based on the generalized Huygens-Fresnel diffraction principle and the unified theory of coherence and polarization of light beams, the polarization change of Gaussian Schell-model beams propagating through the Kolmogorov ocean turbulence was studied, and the conditions of keeping the polarization properties of Gaussian Shell-model beams were analyzed in the Kolmogorov ocean turbulence. The polarization propagating properties of linearly polarized light and circularly polarized light were studied in the ocean turbulence. The results show that the completely polarized light is not affected in the Kolmogorov ocean turbulence.
