•Properties of chirped Gaussian pulsed beam in oceanic turbulence are obtained.•The influence of beam parameters on the on-axis and off-axis spectra shift is studied.•The influence of oceanic turbulence on the on-axis and off-axis spectra shift is obtained.
Based on the extended Huygens-Fresnel principle, the spectral behaviors of a chirped Gaussian pulsed beam propagating in oceanic turbulence are illustrated. The influence of the parameters of oceanic turbulence (the rate of dissipation of turbulent kinetic energy per unit mass of fluid, rate of dissipation of mean-square temperature, relative strength of temperature and salinity fluctuations), relative position parameter and propagation distance on the spectra shift is analysed and given by numerical examples. The research results have the potential application in underwater wireless laser communication and remote sensing.
