TLDR
In this paper, the contribution of tertiary resonant interactions to the total energy transfer in an inhomogeneous random field of gravity waves is calculated, and it is found to be small for open-ocean waves, but to be of some importance for shallow-water waves, where topography or mean shear currents may produce strong inhomogeneities.Abstract:
Certain tertiary resonant interactions of gravity waves which have been found previously can be obtained more easily by using a simple extension of Whitham's formalism. The contribution of these interactions to the total energy transfer in an inhomogeneous random field of gravity waves is calculated. It is found to be small for open-ocean waves, but to be of some importance for shallow-water waves, where topography or mean shear currents may produce strong inhomogeneities. The nonlinear splitting of the group velocity is found to be unimportant in wave fields with sufficiently smooth spectra.read more

The Interaction of Ocean Waves and Wind
TL;DR: The Interaction of Ocean Waves and Wind describes the two-way interaction between wind and ocean waves and shows how ocean waves affect weather forecasting on timescales of 5 to 90 days as discussed by the authors.

A theory of the imaging mechanism of underwater bottom topography by real and synthetic aperture radar
Werner Alpers,Ingo Hennings +1 more
TL;DR: In this paper, a simple theoretical model of the imaging mechanism of underwater bottom topography in tidal channels by real and by synthetic aperture radar (SAR) is presented, which is attributed to surface effects induced by current variations over bottom topographical features, which in turn gives rise to changes in radar reflectivity.

The damping of ocean waves by surface films: A new look at an old problem
TL;DR: In this article, a wave attenuation by viscoelastic surface films is attributed to the Marangoni effect, which causes a strong resonance-type wave damping in the short-gravity-wave region, and to nonlinear wave-wave interaction, by means of which wave energy is transferred from the longer waves to the energy sink in the MARANGoni resonance region.

The two-frequency microwave technique for measuring ocean-wave spectra from an airplane or satellite
TL;DR: In this paper, the authors investigated the applicability of the two-frequency microwave technique at slant incidence for the measurement of ocean wave spectra, first proposed by Rucket et al. (1972), with respect to its applicability in aircraft and space vehicles.

TL;DR: In this article, wave spectra were measured along a profile extending 160 kilometers into the North Sea westward from Sylt for a period of two weeks in 1968 and 1969, with particular emphasis on wave growth under stationary offshore wind conditions and the attenuation of swell in water of finite depth.

Radiation stress and mass transport in gravity waves, with application to `surf-beats'
TL;DR: In this article, the second-order currents and changes in mean surface level which are caused by gravity waves of non-uniform amplitude are investigated, and the effects are interpreted in terms of the radiation stresses in the waves.
