Examples of anomalies (some of them corrected after detected by objective analysis)Examples of anomalies (some of them corrected after detected by objective analysis)
• Drift on salinity
• Bad data on the last measurement (and first measurement)
• Bad salinity associated to spikes
• Bad data on a part of the profile (doubtful sensor)
How are detected the anomalies ?
What kind of anomalies are detected ?
