              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.  Timing errors are clearly evident
                             during most of 1984-86.
