 The
Wavemonitor is a rugged, reliable wave measuring buoy developed from experience
gained from over 25 years of wave measurement in the notoriously extreme ocean
environment off the southern African coast. It has been thoroughly tested and
satisfactorily compared to other commercially available wave buoys.
Sea surface displacement with time is derived from the displacement obtained
through double-integrating the vertical acceleration of the buoy. The buoy
features an inertially stabilised accelerometer transducer which is insensitive
to either horizontal or rotational movement. The wave data are transmitted to a
Wavelogger shore station by means of HF radio.
