A new kind beam called the random electromagnetic multi-Gaussian Schell-model (REMGSM) vortex beam has been introduced. Based on the Huygens–Fresnel principle, the elements of the cross-spectral density matrix of the REMGSM vortex beam propagation in oceanic turbulence have been derived. The average intensity and spectral degree of polarization properties of the REMGSM vortex beam propagating in oceanic turbulence are illustrated and analyzed using numerical examples. The results show that the REMGSM vortex beam propagating in stronger oceanic turbulence will evolve into flat-topped beam and Gaussian-like beam more rapidly as the propagation distance increases.
