| Benchmarks | |
| Tide gauge benchmarks | Benchmark bolt inside tide gauge hut adjacent to stilling well. Acoustic gauge is referred to the same benchmarks as the float gauge. Aquatrack levelling point is 10.000m above an arbitrary 'zero'. |
| Benchmark relationships | Tide gauge zero (TGZ) = local chart datum TGZ = 5.52m below TGBM (from 1951 onwards) NOAA Gage 0 is designated as 2.0000m below chart zero. Chart zero refers to MLLW, indicated on the Plano de Reduccion de la Carta Argentina. |
| Auxiliary benchmarks | AUX 1: Punto fijo ubicado frente la Base Naval Ushuaia, en las adyacencias de la Comandancia Other benchmarks include: 1000 A 1991, 1000 B 1991, Unstamped 1, Unstamped 2, II, MOJON X1 1978. |
| Data at PSMSL | |
| Annual MSL (RLR) data | |
| Annual MSL (RLR) plot | |
| MSL method | mean monthly hourly heights |
| PSMSL code | 1271 |
| Other relevant codes | UHSLC 600 |
| Additional information | |
| Other relevant information | Gauge was moved 900m in May 1970. PSMSL hold data collected prior to move (PSMSL Code 860/001, 1957-1969). |
