Internal Cylinder Identification Based on Different Transmission of Longitudinal and Shear Ultrasonic Waves

open access: yesSensors, 2021
We have built a Fizeau fiber interferometer to investigate the internal cylindrical defects in an aluminum plate based on laser ultrasonic techniques. The ultrasound is excited in the plate by a Q-switched Nd:YAG laser. When the ultrasonic waves interact

A Model Sensitivity Study of Ocean Surface Wave Modulation Induced by Internal Waves

open access: yesEarth and Space Science, 2022
Nonlinear internal waves are an upper ocean phenomenon that drives horizontal surface current gradients, which in turn modulate ocean surface waves. Under certain conditions, this wave‐current interaction creates ocean surface roughness heterogeneity, in

An Introduction to the Special Issue on Internal Waves [PDF]

open access: yesOceanography, 2012
This special issue of Oceanography presents a survey of recent work on internal waves in the ocean. The undersea analogue to the surface waves we see breaking on beaches, internal waves play an important role in transferring heat, energy, and momentum in

Internal Waves on the Washington Continental Shelf [PDF]

open access: yesOceanography, 2012
The low-frequency oceanography of the Washington continental shelf has been studied in great detail over the last several decades owing in part to its high productivity but relatively weak upwelling winds compared to other systems.

Variability of Internal Wave Strain Over the Western Boundary Region in the North Atlantic

open access: yesFrontiers in Earth Science, 2022
Based on the CTD profiles and mooring measurements of the Line W program in the North Atlantic about 35°N/70°W, we investigated the spatial variability of internal wave-induced strain variance along the Line W section and the associated reasons.

Noise of Internal Solitary Waves Measured by Mooring-Mounted Hydrophone Array in the South China Sea

open access: yesJournal of Marine Science and Engineering, 2022
Internal solitary waves in the South China Sea have attracted attention because of their large amplitude and high rate of occurrence. Internal solitary waves have a substantial influence on underwater sound propagation and ambient noise.

Mass and momentum transfer by solitary internal waves in a shelf zone [PDF]

open access: yesNonlinear Processes in Geophysics, 2012
The evolution of large amplitude internal waves propagating towards the shore and more specifically the run up phase over the "swash" zone is considered.

The Generation of Nonlinear Internal Waves [PDF]

open access: yesOceanography, 2012
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, including by lee waves, tidal beams, resonance, plumes,

Observations of internal waves generated by an anticyclonic eddy: a case study in the ice edge region of the Greenland Sea

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2019
Internal waves in the ocean play an important role in turbulence generation due to wave-breaking processes and mixing of the ocean. Airborne radar images of internal waves and ocean eddies north of Svalbard suggested that ocean eddies could generate ...
