A new wave buoy powered by solar panels, which can measure the three axes
acceleration of the buoy, pitch and roll, has been developed. Non-directional wave
spectra are calculated from measured acceleration time series of the buoy. A real time
algorithm for estimating wave information (including wave spectra, significant wave
height, mean wave direction, principle wave direction, etc.) is described in this paper.
In order to evaluate data consistency, a comparison of the wave parameters from two
different buoys is presented.
