Shallow Water '06: A Joint Acoustic Propagation/Nonlinear Internal Wave Physics Experiment
Wave Joint Acoustic Propagation
2015/7/22
Since the end of the Cold War, the US Navy has had an increasing interest in continental shelves and slopes as operational areas. To work in such areas requires a good understanding of ocean acoustics...
Nonlinear Internal Waves in Synthetic Aperture Radar Imagery
Nonlinear Internal Waves Synthetic Aperture Radar Imagery
2015/7/16
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 w...
Nonlinear internal waves are found in many parts of the world ocean. Their widespread distribution is a result of their origin in the barotropic tide and in the variety of ways they can be generated, ...

Turbulent mixing induced nonlinear internal waves Mono Lake California
2014/4/17
Describing the spatial and temporal occurrence of turbulent mixing and the mechanisms of turbulence production are fundamental problems in physical limnology and oceanography. Here we present results ...
Fully Nonlinear Shallow Water Waves Simulation Using Green-Naghdi Theory
Green-Naghdi theory model fully nonlinear water waves shoaling waves
2011/9/8
Green-Naghdi (G-N) theory is a fully nonlinear theory for water waves. Some researchers call it a fully nonlinear Boussinesq model. Different degrees of complexity of G-N theory are distinguished by “...
