Geographical Variability of the Internal Wave Field：A Search for Sources and Sinks
Geographical Variability Internal Wave Field
2009/3/7
Internal wave records from a variety of deep water locations in the North Atlantic have been reduced by common analysis methods in a search for systematic deviations from a universal spectral model. S...
Covariance Functions and Spectra of a Random Wave Field
Covariance Functions Random Wave Field
2009/3/7
Covariance functions and spectra of components of fluid particle velocity are obtained, taking into consideration the effects of free surface fluctuations, for a Gaussian, stationary and homogeneous r...
Equilibrium Mechanisms within the Oceanic Internal Wave Field
Equilibrium Mechanisms Oceanic Internal Wave Field
2009/3/7
Numerical computations indicate that the nonlinear self-interaction mechanisms, induced diffusion and elastic scattering generate a universal equilibrium spectrum of deep ocean internal waves. This sp...
The Influence of the Directional Energy Distribution on the Nonlinear Dispersion Relation in a Random Gravity Wave Field
Directional Energy Distribution Nonlinear Dispersion Relation Random Gravity Wave Field
2009/3/7
The influence of the directional distribution of wave energy on the dispersion relation is calculated numerically using various directional wave spectrum models. The results indicate that the dispersi...
Vertical Coherence of the Internal Wave Field from Towed Sensors
Vertical Coherence Vertical Coherence Towed Sensors
2009/2/13
Constant depth and isopycnal-following tows are used to estimate the, towed vertical coherence of the internal wave field, at vertical separations of 8.5, 18, 28 and 70 m. The depths of the tows are 7...
Observations of the Horizontal Interactions between the Internal Wave Field and the Mesoscale Flow
Horizontal Interactions Internal Wave Field Mesoscale Flow
2009/2/10
Momentum and energy transfers from the mesoscale horizontal velocity shear to the internal wave field have been deduced from an analysis of a closely spaced, 25 km, moored current-meter array. The cor...
Kinematics of Turbulence Convected by a Random Wave Field
Turbulence Convected Random Wave Field
2009/2/6
Turbulent velocity spectra measured beneath wind waves show a large enhancement about the central wave frequency. A “5/3" frequency dependence can be seen both above and below the central peak, but wi...
Doppler Sonar Observations of Internal Waves, Wave-Field Structure
wave field near-inertial tidal peaks
2009/2/5
During May of 1980 an internal-wave-measurement experiment was conducted from the Research Platform FLIP off the California coast. This paper discusses an 18-day sequence of velocity profiles obtained...
Multimodal Properties of the Surface-Wave Field Observed with Pitch-Roll Buoys During GATE
GARP Tropical Atlantic Experiment Surface-Wave Field Pitch-Roll Buoys

A sophisticated analysis technique is applied to a subset of pitch-roll buoy data collected by the research vessels Gilliss and Quadra during the GARP Tropical Atlantic Experiment (GATE) in September ...
Detection of Breaking Events in a Wind-Generated Wave Field
Wind-Generated Wave Field fetch-limited wave field wave breaking
2009/1/21
Measurements were made of the surface elevation of a fetch-limited wave field (fetch 7 km, wind speed about 6 m s−1). Good high-frequency response was attained by the use of a very thin, bare wi...
Variability in the Upper-Ocean Internal Wave Field at a Sargasso Sea Site
