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 import...
Propagating and evanescent internal waves in a deep ocean model
Propagating evanescent internal waves deep ocean model
2012/2/28
We present experimental and computational studies of the propagation of internal waves in a stratified fluid with an exponential density profile that models the deep ocean. The buoyancy frequency prof...
Investigating internal waves east of the Hainan Island using optical satellite remote sensing data
internal wave formation mechanism marginal water east of the Hainan Island satellite remote sensing
2009/11/17
Marginal water of east Hainan Island was an area that internal waves occurred frequently, however, few studies was found and mechanism for internal waves formation was unclear. In the paper, China Bra...
On a spectrum of nonlinear internal waves in the oceanic coastal zone
spectrum nonlinear internal waves oceanic coastal zone
2009/11/3
This paper studies the internal wave band of temperature fluctuation spectra in the coastal zone of Pacific ocean. It is observed that on the central Mexican Pacific Shelf in the high-frequency band o...
Energy densities as a function of frequency of the vertical and relative horizontal velocities of water in the deep ocean as measured at clusters of neutrally buoyant floats are compared for different...
Spectra of Internal Waves：In-Situ Measurements in a Multiple-Layered Structure
Internal Waves Multiple-Layered Structure In-Situ Measurements
2009/4/3
The persistence of layering between 200 and 400 m depth in the Arctic Ocean has enabled construction of accurate internal wave amplitude traces from a 30-hr series of successive temperature profiles t...
Observed Anisotropy of Spectral Characteristics of Internal Waves Induced by Low-Frequency Currents
Spectral Characteristics Internal Waves Low-Frequency Currents
2009/3/26
The isotropy of the internal wave field is investigated from short-time spectra of horizontal current measured in the deep sea. A significant anisotropy is detected at high frequencies during most per...
Vertical Diffusion Driven by Internal Waves in a Sill Fjord
Vertical Diffusion Driven Internal Waves Sill Fjord
2009/3/7
A new mechanism, the breaking of internal waves, is proposed to explain vertical mixing within the lower layers of sill fjords. The generation of the waves at the sill of a fjord is modelled assuming ...
Impingement of Internal Waves from Below onto a Moving Mixed Surface Layer
Internal Waves Moving Mixed Surface Layer
2009/3/7
Discussion of the generation of internal waves by tidal flow over bottom topography concludes that isobath convergence has an important effect on wave intensity near the sea surface, and also predicts...
Discrimination between Internal Waves and Temperature Finestructure
internal wave experiment Temperature Finestructure Internal Waves
2009/3/7
Discrimination between internal waves and finestructure in the ocean is made difficult because of over-lapping scales of each process. We have assumed as a working hypothesis that low frequency/wavenu...
Observations of Long Nonlinear Internal Waves in a Lake
Long Nonlinear Internal Waves Lake
2009/2/23
This paper describes observations of large-amplitude, long internal waves in Babine Lake. A unique feature of the observations is that they were taken simultaneously at several different points along ...
Boundary Layer under Near-Inertial Internal Waves over a Critically Sloping Bottom
Boundary Layer Critically Sloping Bottom Near-Inertial Internal Waves
2009/2/18
Internal waves reflecting off sloping bottoms have been shown to have boundary-layer scales proportional to ν½ (ν is viscosity). As the characteristic slope of the wave approaches the slope of ...
It is shown that the oceanic internal wave field is too energetic by roughly two orders of magnitude to be treated theoretically as an assemblage of weakly interacting waves. This may be seen both fro...
An experiment was performed in the Gulf of Cadiz during June 1977, with the objective of separating oceanic variability due to internal waves from that due to inhomogeneities of the water. A CTD which...
A Theory of the Mean Flow Driven by Long Internal Waves in a Rotating Basin, with Application to Lake Kinneret
Mean Flow Driven Rotating Basin Long Internal Waves
2009/2/13
The rectified flow induced by wind-driven internal seiches in a rotating lake is studied. Friction and nonlinearity combine to generate a secondary mean flow which is calculated analytically for the c...
