Hourly:
Unconfirmed.
Daily:
119-point convolution filter (Bloomfield, 1976) centred 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.
Span of Data:

All data are referred to tide gauge zero and linked to historic fixed bench marks.
Comment:
The daily or monthly means do not reveal any obvious reference level shifts. Most questionable fluctuations are related to timing problems with the gauge.
