| Benchmarks | |
| Tide gauge benchmarks | Hydro-benchmark situated on the top of the well |
|---|
| Benchmark relationships | Tide gauge zero (TGZ) = zero hydrographic
TGZ = 2.78m below TGBM
TGBM = 1.03m below benchmark BM: rivet set on the beacon in front of the tide gauge hut
|
|---|
| Auxiliary benchmarks | Rivet set on the beacon in front of the gauge, 3.81m above zero hydrographic |
|---|
| Data at PSMSL | |
| MSL method | Doodson X0 filter |
|---|
| Additional information | |
| Other relevant information | The tide gauge has been adjusted by direct surveying with the hydrographic zero reference. The zero of tide state coincides with the hydrographic zero reference. |
