              Present Data : Hourly, daily, and monthly values obtained by:
                    Hourly : 3-point Hanning Filter centered on the hour
                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data        
                             with respective periods of the 95, 50, and 5%      
                             amplitude points at 124.0, 60.2, and 40.2 hours    
                    Monthly: Simple average of all daily values; calculated if  
                             7 or fewer days are missing

              Refernce Levl: The data have been linked to tide staff zero by    
                             the originators.  The site was moved in 2010
                             though benchmarks between the sites have not been
                             linked so the series are separated into 729A
                             and 729B.
                          Tide Gauge Benchmarks: benchmark bolt inside tide
                             gauge hut adjacent to stilling well.  Acoustic
                             gauge is referred to the same benchmark as the
                             float gauge.  Aquatrack Levelling Point designated
                             as 10.000m above an arbitrary zero.
                          Auxiliary benchmarks: 
                             Aux 1: Punto fijo No. 11, ubicado al pie de la
                             cuarta columna contando desde la entrade, en el
                             muelle del Club de Pescadores de Mar del Plata.
                          Benchmark relationships:
                             Tide gauge zero (TGZ) = local chart datum
                             TGZ = 0.91m below 'O' IGM
                             TGZ = 5.74m below TGBM (from 1949 onwards)
                             NOAA Gauge Zero designated exactly 2 metres
                             below chart zero.  Chart zero refers to MLLW as
                             on the Plano de Reduccion de la Carta Argentina.
              Comment      : The hourly residuals show large fluctuations 
                             with 2-4 day periods associated with weather
                             or shelf waves.
