History Summary
| Station Name | Esperanza |
|---|---|
| Country | Argentina |
| Latitude | 63° 23.7' S |
| Longitude | 056° 59.7' W |
| Time Reference | GMT (00-23 hours) |
| GLOSS No. | 185 |
| Contributor | University of Hawaii Sea Level Center
1000 Pope Rd. MSB 317 Honolulu, Hawaii 96822 |
| Originator | National Ocean Service (NOS)
National Ocean. and Atmos. Administration (NOAA) N/OES22 SSMC4, Station 7109 1305 East West Highway Silver Spring, MD. 20910-3233 |
| Instrument Type | Aquatrak acoustic sensor
Due to terrain constraints, the station design had to be modified and the acoustic sensor was installed 45° from the vertical. |
| Backup Systems | IMO pressure sensor gauge, NOAA Next Generation Water Level Measuring System (NGWLMS)
Two digi-bubblers (very high precision pressure sensors). Three sensors guarantee the continuity of observations during the period when the water freezes. |
| Observational Period | 1996-1998 |
Tide gauge Benchmark (TGBM) Description
Benchmark bolt inside tide gauge hut adjacent to stilling well.
Auxiliary Benchmarks
Pilar de referencia ubicado en cercauias de la estacion.
Benchmark Relationships
Tide gauge zero (TGZ) = Local Chart Datum
TGZ is 5.45m below TGBM
Datum Information
The sea level heights were originally referred to the zero point assigned to the tide gauge.
Please Note . Original data adjusted by -7000mm to fit the JASL format.
