Internal solitary waves (ISWs) and large-amplitude internal soliton packets are usual event in the oceans and stratified estuaries. In the oceans ISWs are mainly generated by the interaction of the barotropic tides with the bottom topography, however passages of strong storms and typhoons over topographic features also may generate highly nonlinear ISWs. Information about flows due to internal waves, their origin, propagation and influence on the surrounding is of great importance. Large amplitude solitary waves are energetic events generating strong current. They also can trap fluid with larvae and sediments in the cores of waves and transport it at the considerable distance. ISWs can cause hazard to marine engineering and submarine navigation and significantly impact on marine ecosystems and particle transport in the bottom layer of the ocean and stratified lakes. This session invites contributions on all aspects of ISWs generation, propagation, transformation and interaction of internal waves with a bottom topography and shelf zones and evaluation the role of internal waves in resuspension and sediment transport. Breaking of internal-waves also driven turbulent mixing in the ocean interior that is important for climate ocean models. Discussion about parameterizations for internal-wave driven turbulent mixing in global ocean models is also appreciated.
