Comments
The residual series are very noisy which is probably due to shallow water tides that are not resolved by the harmonic analysis. Consequently, only questionable fluctuations greater than 40 cm are noted below that may represent timing inaccuracies.
The daily plot shows noise due to a great amount of energy with periods from 3 to 15 days. The monthly plot reveals a consistent annual and semi-annual signal.
