Internal Wave-Driven Surface Currents From HF Radar
Internal Wave-Driven Surface Currents HF Radar
2015/8/10
Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
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...
The sun inputs huge amounts of heat to the ocean, heat that would stay near the ocean's surface if it were not mechanically mixed into the deep. Warm water is less dense than cold water, so that heate...
From Luzon Strait to Dongsha Plateau:Stages in the Life of an Internal Wave
Luzon Strait Dongsha Plateau Internal Wave
2015/7/13
Tidal currents in Luzon Strait south of Taiwan generate some of the largest internal waves anywhere in the ocean. Recent collaborative efforts between oceanographers from the United States and Taiwan ...
The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...
The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Internal Wave Strain Fine-Structure Vertical Spectra
2009/4/2
Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The f...

Philips has pointed out that the measurement of the internal wave spectrum and coherence in a stratified medium is distinctly altered when the profile contains fine-scale layers. Garrett and Munk demo...
Internal Wave Dispersion Calculated Using the Thomson-Haskell Method
Internal Wave Thomson-Haskell Method
2009/3/24
The dispersion and amplitude characteristics of internal wave motion are determined by a matrix method which lends itself readily to computer analysis. A layered density structure may be chosen to fit...
Internal Wave Reflection by a Velocity Shear and Density Anomaly
Internal Wave Velocity Shear Density Anomaly
2009/3/24
Numerical solutions are obtained for the reflection of upward propagating internal waves by simple pycnocline and current shear models. Results for a simple monotonic shear and a velocity jet, with an...
