Tide gauge benchmarkBench mark bolt next to tide gauge
Benchmark relationshipsTide gauge zero (TGZ) = Admiralty chart datum.
TGZ = 5.58m below the fundamental benchmarks which are derived and established from the Rifleman Copper Bolt
Auxiliary benchmarksLocal benchmarks are installed near the tide stations. The local benchmarks are surveyed twice a year to check if there is any land settlement that may affect the tidal readings.
