Internal Wave Spectra in the Presence of Fine-Structure
Internal Wave Spectra Fine-Structure
2009/3/9
Phillips has shown that an undulating motion of a layered medium relative to a measuring instrument will result in a σ−2 spectrum (frequency or wavenumber) over a bandwidth determined by the thi...
Internal Wave Spectra at the Buoyant and Inertial Frequencies
Internal Wave Spectra Buoyant Inertial Frequencies
2009/2/19
Spectra of the vertical displacement (potential energy) have been observed to be only slightly enhanced at the buoyancy frequency ω = N, whereas spectra of horizontal velocity u, v (kinetic energy) ar...

Directional Wave Spectra Observed JONSWAP 1973
2009/2/18
Estimates of the directional wave spectrum obtained from the meteorological buoy of the University of Hamburg and a pitch-and-roll buoy of the Institute of Oceanographic Sciences are reported from a s...
Daylight Imagery of Ocean Surface Waves for Wave Spectra
surface-reflected daylight Ocean Surface Waves upwelling light Wave Spectra
2009/2/9
Both surface-reflected daylight and upwelling light are modeled to second order to help provide a quantitative and physically interpretable description of daylight imagery of ocean surface waves for w...
On the Effects of Finite Depth on Wind-Wave Spectra：1. A Comparison with Deep-Water Equilibrium-Range Slope and Other Spectral Parameters
Wind-Wave Spectra Deep-Water
2009/2/7
Spectral parameters calculated from wind-wave measurements in a finite-depth restricted-fetch estuary are compared with similar deep-water parameters. The equilibrium range of these finite-depth spect...
Sea-Tower Measurements of Wind-Wave Spectra in the Caspian Sea
Sea-Tower Measurements Caspian Sea Wind-Wave Spectra
2009/1/19
High frequency spectra of wind generated waves corresponding to mean wind speeds from 3.5 to 13.5 m s−1 were measured at the research tower in the Caspian Sea. The techniques used made it possib...
Implications of Ocean Bottom Reflection for Internal Wave Spectra and Mixing
Ocean Bottom Internal Wave
2009/1/16
A linear internal wave model for reflection off a sloping bottom applied to a field of horizontally isotropic waves typical of the deep ocean leads to a strongly perturbed frequency-vertical wavenumbe...
Directional Wave Spectra Measured with the Surface Contour Radar
Directional Wave Surface Contour Radar
2009/1/15
The Surface Contour Radar is a 36-GHz computer-controlled airborne radar which generates a false-color coded elevation map of the sea surface below the aircraft in real-time, and can routinely produce...
Maximum Entropy Estimation of the Directional Distribution in Ocean Wave Spectra
Maximum Entropy Estimation Directional Distribution Ocean Wave Spectra
2009/1/13
A general maximum entropy estimate for the directional distribution of the directional wave spectrum is introduced. The estimate appears to be superior to conventional methods, including maximum likel...

2008/12/30
An improved method for estimating the directional spectrum of linear surface gravity waves from in Situ observations is presented. The technique, a refinement and extension of the inverse method of Lo...
The Dissipation Range of Wind-Wave Spectra Observed on a Lake
Wind-Wave Spectra deep water Dissipation Range
2008/12/27
Based on an interpretation of a field experiment it is argued that, due to breaking of wind waves in deep water, the dissipation of energy is restricted to a range of frequencies ω > ωg, much higher t...
