It is well known that wave dispersion in inhomogeneous media leads to energy flux weakening on large distances. The more interesting cases are when inhomogeneity does not prevent wave propagation. This problem is studied here for internal waves in the ocean. Firstly, the penetration of internal waves into a deep ocean, stratified with density and current, is discussed, and it is shown that there is sufficient number of stratification profiles allowing non-reflected wave propagation into the ocean bulk. Further the internal wave propagation in two-layer stratified ocean of variable depth is investigated. The set of bottom profiles where the wave energy is not scattered, is also found.
