              Comment      : The daily and monthly means reveal no              
                             apparent reference level changes or trends.        
                             The hourly residuals have periodic fluctuations    
                             which are most likely due to the harmonic analysis 
                             not being able to completely resolve all the tidal 
                             constituents.  However, some of the periodic       
                             fluctuations may be the result of timing errors.
