5. Annual Meeting, June 15-16 2015, Istanbul, Turkey Data quality control performed by the RIHMI-WDC: Type of QC:Seawater Position check+ Date check+ Missing value+ Range check+ Spike+ Visualization and manual checks+

6. 2-nd annual Meeting, June 15-16 2015, Istanbul, Turkey Difficulties encountered: Many duplicates of oceanographic stations for one cruise, selected the CDI checker program. Reason: The Russian data are the time series in frame one cruise or many times the oceanographic stations for one fixed point. Propose: It need to modify the CDI checker program. The rule: If the coordinates (latitude and longitude) of oceanographic stations are identical and times are differing more 30 minutes, than these stations no duplicates.

7. 2-nd annual Meeting, June 15-16 2015, Istanbul, Turkey Planning for the next year Total number of stations for: - Baltic Sea - nearly 13000 stations - Black Sea - nearly 12000 stations
