Tide Gauge Benchmark (TGBM) Description

All heights have been referred to station tide staff zero which is linked to fixed benchmarks. The controlling benchmark is BM 651, 1944, which is 9.904m above chart datum.

Quality Assessment

Comment

The hourly residuals show significant fluctuations within the tidal frequency band. It is not clear whether this is due to the inability of the tidal analysis to resolve the complex nature of the tides or errors in the timing of the instrument. Only the extreme fluctuations are listed below.
