Comments

The tidal analysis was unable to resolve all the harmonic constituents in the data thus the hourly residuals contain uncertain periodic signatures.

The daily and monthly means reveal no apparent changes in the reference level.

This series is distinguished from Pohnpei-B because the two series are not linked to the same tide staff zero.
