In this paper, we theoretically analyze the beam wander variance for Gaussian propagation through weak oceanic turbulence. Particularly, consider effect of eddy diffusivity ratio salinity to temperature as well outer scale on wander. To get tractable theoretical results, first develop an approximate refractive-index spectrum with and variable ratio. Based in turbulence, then derive closed-form expression variance. We present numerical results show that is either overestimated or...
