FIELD TEST OF BURIED OCEAN-WAVE DIRECTIONAL SPECTOMETER SYSTEM

This paper presents a new and unique method of measuring the directional spectra of ocean surface waves with a buried instrument containing horizontally oriented seismometers and a pressure sensor. Based upon the assumption that the seabed responds in an elastic, incompressible, and linear manner to ocean wave-induced pressure fluctuations, the directional spectrum of the sediment motion has been found using the maximum entropy method. This motion is converted to a surface-wave directional spectrum.
