Abstract : A single small buoy, either free-floating or tethered to an anchor, is designed not to follow the slope of the water surface, but instead to pitch and roll according to the orbital particle-velocity gradient. The dynamics of this buoy system are such that the data obtained on heave, pitch, roll, and compass bearing can be transformed into complete directional wave spectra. The data processing technique is presented in this paper, and applied to an ocean storm experiment. The buoy used to produce these data was an Endeco Model 956 Wave-Track buoy and the experiment was conducted as part of ARSLOE (Atlantic Remote Sensing Land-Ocean Experiment, fall 1980).
