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.

Studies in Applied Mathematics, 1992
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.

Internal Waves in the Clyde Sea
Estuarine, Coastal and Shelf Science, 2002Temperature measurements were made with 15 s and 1 min sampling intervals in the thermocline of the Clyde Sea to assess the variability associated with internal waves on time scales from min to hours. The data were collected during shallow water acoustics experiments which took place near Troon during the summer of 1997.

THE INTERNATIONAL DATABASE ON WAVE OVERTOPPING
Coastal Engineering 2004, 2005One of the main objectives within the EU-project CLASH (www.clash-eu.org) was to create a generic prediction method for wave overtopping at coastal structures by means of the Neural Network technique. An extensive and homogeneous database on wave overtopping was set up within CLASH, mainly with the aim to be used for the training process of the Neural ...

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 ...

Internal Waves on River Plumes
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018We present results of observations of internal waves (IW) on the river plumes caused by the spread of the front of fresh waters, based on satellite images of the visible range obtained by Sentinel-2A Multispectral Imager Instrument (MSI/S2) and Landsat-8 Operational Land Imager (OLI/L8) instruments. Due to the high spatial resolution of these satellite

Surface waves excitation by internal wave
OCEANS 2011 IEEE - Spain, 2011Internal waves (IW) represent one of the most interesting and not so well-studied phenomena in the ocean dynamics. Though these waves exist virtually everywhere, an experimental databank on their measurement is rather limited. Currently, along with contact measurements, another line of inquiry is actively developed, that is the remote study of IWs by ...

The focusing of surface waves by internal waves
Journal of Fluid Mechanics, 1999The surface current generated by internal waves in the ocean affects surface gravity waves. The propagation of short surface waves is studied using both simple ray theory for linear waves and a fully nonlinear numerical potential solver. Attention is directed to the case of short waves with initially uniform wavenumber, as may be generated by a

Are Solitary Internal Waves Solitons?
Studies in Applied Mathematics, 1998Results of fully nonlinear numerical simulations of the interaction of two mode‐1 solitary internal waves, both propagating in the same direction, are presented. After the interaction, two solitary internal waves emerge. The large wave is slightly larger than the initial large solitary wave, while the small one is slightly smaller than the initial ...

Oceanic Internal Waves Are Not Weak Waves
Journal of Physical Oceanography, 1980Abstract It is shown that the oceanic internal wave field is too energetic by roughly two orders of magnitude to be treated theoretically as an assemblage of weakly interacting waves. This may be seen both from recent weak wave theoretical calculations which contradict their premises and also from inspection of magnitudes of advection and wave ...
