Project Information
World Ocean Circulation Experiment (WOCE)
The World Ocean Circulation Experiment (WOCE) was a major international experiment which made measurements and undertook modelling studies of the deep oceans in order to provide a much improved understanding of the role of ocean circulation in changing and ameliorating the Earth's climate.
WOCE had two major goals:
-
Goal 1. To develop models to predict climate and to collect the data necessary to test them.
-
Goal 2. To determine the representativeness of the Goal 1 observations and to deduce cost effective means of determining long-term changes in ocean circulation.

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.
Parameters
| Period | Parameters | CI% | Sample interval |
|---|---|---|---|
| 1996 | ASLVZZ01 | 96 | 60 minutes |
| 1997 | ASLVZZ01 | 70 | 60 minutes |
| 1998 | ASLVZZ01 | 61 | 60 minutes |
Where:
ASLVZZ01 = Sea Level (metres)
Quality Assessment
All data have been compared with the current Harmonic Constants Library, and residuals checked. Records have been visually inspected for spikes, datum shifts and timing errors.
| Period | Parameter | Missing data | Suspect data |
|---|---|---|---|
| 1996 | ASLVZZ01 | 001-017 | None |
| 1997 | ASLVZZ01 | 195-304 | None |
| 1998 | ASLVZZ01 | 164-187,243-365 | None |
