Seabed Dynamic Responses Induced by Nonlinear Internal Waves: New Insights and Future Directions

Journal of Marine Science and Engineering, 2023
Strong nonlinear internal waves generate a significant pressure force on the seafloor and induce a pore-pressure response penetrated in the seabed and are thus an important driver of sediment resuspension and a potential trigger of seabed failure.

Nonlinear Internal Waves in Synthetic Aperture Radar Imagery [PDF]

Oceanography, 2013
Synthetic aperture radar (SAR) has contributed significantly to the study and understanding of oceanic nonlinear internal waves. Although they travel within the ocean's interior, currents associated with internal waves produce variations in ocean surface

Conventional Partial and Complete Solutions of the Fundamental Equations of Fluid Mechanics in the Problem of Periodic Internal Waves with Accompanying Ligaments Generation

Mathematics, 2021
The problem of generating beams of periodic internal waves in a viscous, exponentially stratified fluid by a band oscillating along an inclined plane is considered by the methods of the theory of singular perturbations in the linear and weakly nonlinear ...

Observations of enhanced nonlinear instability in the surface reflection of internal tides [PDF]

, 2013
Enhanced vertically standing waves formed by the superposition of two upward and downward going near-diurnal (D1) waves are observed during one semidiurnal (D2) spring tide in an approximately 75day long velocity record from the northeastern South China ...

Simulations and observation of nonlinear internal waves on the continental shelf: Korteweg–de Vries and extended Korteweg–de Vries solutions [PDF]

Ocean Science, 2017
Numerical solutions of the Korteweg–de Vries (KdV) and extended Korteweg–de Vries (eKdV) equations are used to model the transformation of a sinusoidal internal tide as it propagates across the continental shelf.

Nonlinear Fate of Internal Wave Attractors [PDF]

Physical Review Letters, 2013
We present a laboratory study on the instability of internal wave attractors in a trapezoidal fluid domain filled with uniformly stratified fluid. Energy is injected into the system via standing-wave-type motion of a vertical wall. Attractors are found to be destroyed by parametric subharmonic instability (PSI) via a triadic resonance which is shown to

Multi-Sensor Observations Reveal Large-Amplitude Nonlinear Internal Waves in the Kara Gates, Arctic Ocean

Remote Sensing, 2023
We present multi-sensor measurements from satellites, unmanned aerial vehicle, marine radar, thermal profilers, and repeated conductivity–temperature–depth casts made in the Kara Gates strait connecting the Barents and the Kara Seas during spring tide in

Stability of Spatial Optical Solitons [PDF]

, 2000
We present a brief overview of the basic concepts of the soliton stability theory and discuss some characteristic examples of the instability-induced soliton dynamics, in application to spatial optical solitons described by the NLS-type nonlinear models ...
