                          The CSIR makes use of Datawell's Directional Waverider
                          Mark II, Directional Waverider MKIII,
                          Directional Waverider DWR4, as well as
                          the non-directional Waverider SG buoys to measure waves. 
                         
                        Datawell has a history of over
                          40 years in the oceanographic instrumentation arena,
                          and their wave height measuring buoys have been the
                          world standard during this period. Their buoys are
                          accurate and have well-proven stabilized platform
                          sensors. They have, for example, standard integrated
                          data loggers, flash cards that store up to 2 Gbyte of
                          measured data, standard GPS position monitoring,
                          and a HF link for ranges up to 50 km.
