Hydrodynamic modulation of wind waves by long surface waves in a wave tank is investigated, at wind speeds ranging from 1.5 to 10 m s−1. The results are compared with the linear, non-dissipative, theory of Longuet-Higgins & Stewart (1960), which de

An investigation of the hydrodynamic modulation of 1- to 3.5-cm wind waves in a wave tank is described. The modulation of short waves at wind speeds from 4 to 10 m s−1 was due to a mechanically generated 2-s surface wave. Measurement of the surface

In a new application of stereophotography, the three components of the surface current can be obtained directly. The method does not require the deployment of an instrument in the water, or extrapolation of a subsurface measurement to the ocean surfa

Synthetic aperture radar (SAR) images obtained in the SAR and X Band Ocean Nonlinearities: Chesapeake Light Tower (SAXON:CLT) experiment are processed with long integration times (6 s) and analyzed to study the effects of focusing. Two images with ne

The Gulf of Alaska SAR experiment was conducted during March 9–14, 1984 to investigate SAR imaging of narrow-V wakes in a deep mixed layer environment so that surface manifestations of ship-generated internal waves would be made small. Five SAR fli

Modulation of short waves by surface currents subjected to wind input and breaking dissipation is investigated. The dissipation is expressed as a power law function of the action density. The solution is presented in the form of an integral equation,
