Tide Gauge Benchmark (TGBM) Description

All heights have been referred to the station tide staff zero which is linked to fixed benchmarks. The primary benchmark is a bronze tablet (stamped T.S.1.1953) set horizontally in the S face of the south bridge caisson, 0.20m above granite sill and 15m north of the gauge house.

Quality Assessment

Comments

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

Possible datum shift of - 0.5m on 01 April 1976
