Experiments with a Free Floating Wave Buoy.
Abstract
A free-floating wave meter was used to obtain a time series of wave-induced pressure variations in deep water. The meter's response was roughly checked against a piston-type pressure testing apparatus. Techniques in the operation of the meter were developed involving a slight modification in the suspension of the sensor. Power spectra of the pressure variations were obtained from the digitized wave record via the amplitude spectra given by the fast Fourier transform. Characteristics of the power spectra of the metered waves were used to evaluate the meter by comparing them with the waves that might be anticipated (on the basis of theory) from the existing surface wind field and with visual observations of the metered waves.
