Trouble shooting
Caveat from Argo International Steering Team

Argo near real-time data is subject to only coarse fully-automated quality control checks.  No QC is done on Oxygen measurement at present.

Argo delayed-mode procedures for checking sensor drifts and offsets in salinity rely on a statistical comparison of the float data with reference data. An adjustment is made when the float PI judges that it will improve the quality of the dataset. Users should include the supplied error estimates in their usage of Argo delayed-mode salinity data.

For both near real-time and delayed mode data, proper and appropriate use is the responsibility of the user.

Overview
Coriolis data service provides quality-controlled in-situ data in real-time and delayed modes. Managed data sets are mainly T-S profiles and time series from profiling floats, XBT's, thermo-salinographs, drifting and moored buoys.
The service is a gateway to global ARGO data . The centre is the in situ data provider for the Mercator data assimilation project as well as the European Operational Oceanography Mersea project.
Data transmitted by floats are processed, checked for quality and distributed to the GTS and Internet with minimum delay (24 h).
The data service works in close association with a scientific team to define procedures for data validation, quality control, formats and products.
