Internal waves are ubiquitous oceanographic features that occur in various forms across the world’s oceans. They manifest themselves as interface waves across ocean density layers that represent the interplay between buoyancy and gravitational forces, and are typically classified as linear and nonlinear internal waves.

The expansion procedure introduced by Benney (1966) for weakly nonlinear, planar shallow‐water waves is used to provide an alternative derivation of the more general results of Benjamin (1966) for shallow fluid layers possessing arbitrary vertical stratification and horizontal shear.

A numerical solution of the Benjamin–Ono equation for internal waves shows soliton behavior. Two and three Lorentzian solitons pass through one another unscathed. An initial Lorentzian with larger than soliton amplitude decays into solitons, with velocities predicted by the five conservation laws.

The basic theory of internal solitary waves is developed, with the main emphasis on environmental situations, such as the many occurrences of such waves in shallow coastal seas and in the atmospheric boundary layer. Commencing with the equations of motion for an inviscid, incompressible density-stratified fluid, we describe asymptotic reductions to ...

We present the first laboratory evidence of internal gravity wave tunnelling through weakly stratified fluid patches and we derive analytic theories for energy transmission by the waves in two distinct circumstances. In one, the computed transmission coefficient is directly analogous to the textbook calculation for quantum tunnelling of a free electron

Internal wave instability: Wave-wave versus wave-induced mean flow interactions
Physics of Fluids, 2006In continuously stratified fluid, vertically propagating internal gravity waves of moderately large amplitude can become unstable and possibly break due to a variety of mechanisms including (with some overlap) modulational instability, parametric subharmonic instability (PSI), self-acceleration, overturning, and convective instability.

Naturally occurring flows involve fluids of different densities, e.g. warm and cold or fresh and saline waters. Under the action of the gravitational forces, the heavy fluid is lowered and the light fluid raises.

For centuries sea-going explorers and navigators have been aware of the dangers associated with large-amplitude surface gravity waves. Particularly frightening are the giant waves commonly found around the southern tips of South Africa and South America.

Abstract : The overall goal of this PRIMER program is to assess the feasibility of the operation of a synthetic aperture sonar on the continental shelf. To evaluate the performance of this sonar system, knowledge of the fluctuations of oceanic sound speed, primarily due to internal waves, is needed.
