            FIG. 7.13  The 96 stations that comprise the UK wave network ‘WaveNet’. Note the paucity of
            wave buoys in the energetic waters to the west of Scotland. The wave buoys that are clustered in the
            North Sea are part of the network due to collaboration with the oil and gas industry.




            sensor to monitor the direction of north [15]—sufficient information to calculate
            the mean wave direction. Wave buoys which measure their own horizontal
            motion use the Earth’s magnetic field to quantify surge and sway. This surge-
            and-sway motion indicates the mean wave direction. An example of a directional
            wave buoy, and probably the most widely used wave buoy around the world, is
            the Datawell DWR MK III, shown in Fig. 7.14.
