Data quality - TTL160011 - Vega Pleyade SV profiles
At this site, a SVPlus Microsystems Sound velocity probe was used in several profiles.
Profiles were done at these locations:
| Water depth (m) | Latitude | Longitude | Comments |
|---|---|---|---|
| 22 | -52.90327 | -68.1608 | |
| 23 | -52.89312 | -68.22385 | |
| 19.35 | -52.9013 | -68.22104 | Depth provided by Gebco charts |
| 41 | -53.29687 | -67.73704 | |
| 21 | -53.48215 | -68.01857 | |
| 57 | -53.26729 | -67.74705 | |
| 23 | -53.3445 | -67.9082 | |
| 23.5 | -53.35641 | -67.94283 | |
| 46 | -53.29479 | -67.73365 | |
| 14 | -53.35981 | -67.96800 | |
| 50 | -53.29806 | -67.72703 | |
| 20 | -53.34368 | -67.9634 |
Data Quality Information
The following data quality checks were applied:
- Temperature and sound velocity profiles were plotted and compared against each other
- The beginning and the end of each profile were checked and data measured during deployment or recovery were flagged as suspect
Data were found to be good quality. Some cycles at the beginning and at the end of profiles were flagged as suspicious.
Data Access Policy
SIMORC data access conditions
The data collated and held at BODC on behalf of the SIMORC project are restricted. However, the data will be available to download from the Official SIMORC Website, as part of the project protocol. The data set will initially include data from the oil companies TOTAL, Shell and BP.

BODC Processing TTL160011 SV
Data were received by BODC in Excel format. Data was converted in .CSV format and was reformatted to QXF format using BODC transfer function 518. The following table shows how the variables within the files were mapped to the appropriate BODC parameter codes:
| Original parameter name | Original Units | Description | BODC Parameter Code | BODC Units | Comments |
|---|---|---|---|---|---|
| Date/time | DD/MM/YYYY hh:mm:ss | Date and time | AADYAA01 + AAFDZZ01 | Day number and day fraction (GMT) | Conversion by transfer |
| DEPTH | dbar | Pressure at measurements depth | PRESPR01 | dbar | |
| TEMP | degrees Celsius | Water temperature at measurements depth | TEMPST01 | degrees Celsius | |
| SoundVelocity | m/s | Sound velocity at measurements depth | SVELVP01 | m/s |
Following transfer to QXF, the data were screened using BODC's in-house visualisation software, EDSERPLO.

Project Information
System of Industry Metocean data for the Offshore and Research Communities (SIMORC)
The EU-funded SIMORC project is a collaborative effort between MARIS (Netherlands), BODC (UK), the International Association of Oil and Gas Producers (OGP) and IOC-IODE to provide a harmonised and quality controlled metocean data set from data collected by oil and gas producers, accessible through the SIMORC protocol.
