Acoustic Remote Sensing of the Waveheight Directional Spectrum of Surface Gravity Waves

  • Steven H. Hill

Abstract

Knowledge of the directional waveheight spectrum of surface gravity waves on water could be of great importance in improving our understanding of such phenomena as: the generation and propagation of wind waves; air-sea interactions; coastal erosion processes; and others. Engineering studies of the effects of waves on man-made structures such as port facilities, ships, drilling rigs, etc. would be greatly aided by the ability to make precise, reliable measurements of the waveheight directional spectrum. Such measurements are difficult to obtain; there are only a few instruments able to make them routinely, and all these instruments actually float on the surface, thus affecting the measurements by their presence, as well as being subjected to the many and varied mechanical stresses present at the sea surface. Thus the development of an instrument able to make reliable measurements of the surface geometry while remote from the surface would be of considerable scientific and practical importance.
