Datawell directional waverider buoy
|SeaVoX Device Catalogue
|A directional waverider buoy comprising a heave-pitch-roll sensor, two accelerometers and a 3-axis fluxgate compass in a 90cm diameter spherical buoy that measures waves using a translational principle so that horizontal motions rather than wave slopes are measured making the measurement independent of buoy roll motions. A single point rubber cord vertical mooring ensures adequate symmetrical horizontal buoy response to resolve small motions at low frequencies. Data are transmitted to a shore based station and/or an Argos satellite. Three versions of the buoy designated MkI, MkII and MkIII have been produced with evolving internal electronics but fundamentally the same design.
