Strongly Nonlinear Effects on Determining Internal Solitary Wave Parameters From Surface Signatures With Potential for Remote Sensing Applications

Geophysical Research Letters, 2023
The inversion of remote sensing signatures of internal solitary waves (ISWs) can retrieve dynamic characteristics in the ocean interior. However, the presence of ubiquitous large‐amplitude ISWs poses challenges to the commonly used weakly nonlinear ...

Seiche‐Induced Fish Kills in the Sea of Galilee—A Possible Explanation for Biblical Miracles?

Water Resources Research
In Lake Kinneret (the biblical Sea of Galilee), Israel, internal waves of significant amplitude are induced by westerly winds. These waves give rise to upwelling into the surface mixed layer of colder, oxygen‐depleted water from the hypolimnetic and ...

Asymptotic models for internal waves

Journal de Mathématiques Pures et Appliquées, 2008
We derived here in a systematic way, and for a large class of scaling regimes, asymptotic models for the propagation of internal waves at the interface between two layers of immiscible fluids of different densities, under the rigid lid assumption and with a flat bottom.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Interaction of interfacial and internal waves

Fluid Dynamics Research, 1988
Reflection of internal waves at an interface between the mixed layer and a stratified fluid under the layer is investigated experimentally. Reflection coefficients of the internal waves and transmission coefficients of interfacial waves are obtained for the case in which the interfacial waves propagate along the interface. In order to reveal the energy

Nonlinear internal waves in the South China Sea: Observation of the conversion of depression internal waves to elevation internal waves [PDF]

Journal of Geophysical Research: Oceans, 2003
The conversion of depression nonlinear internal solitons to elevation internal waves has been observed twice at the South China Sea continental shelf break. Shipboard X‐band radar, tow‐yo CTD, ADCP and high frequency acoustic flow visualization of the process are presented. The data focuses on up slope propagation of depression internal solitons from a
