5. Result of QC (unrestricted data)
Values. In one dataset, several spikes, no QC performed. Supplier is notified. 75%.

6. ODV file format issues Crucial
Mismatch between header and semantic header
Missing parameters in header
Missing tabs in line (line is discarded)
We are getting better!
Quality is IMPROVING!
Non crucial
Old labels: P011, P061
Parameter names (ex EDMO_CODE)
Empty columns
Missing quality flag column for Depth
Incorrect primary variable
Header = column water header. Semantic header= metadata. PO1=var; PO6=unit. (I ODV anv PO2). ODV is Case sensative!
LOCAL_CDI_ID duplicates

7. Issues encountered and QC
Errors in file format
Wrong primary variable
Missing columns in lines
Missmatch between header ans semantic header
Old vocabulary codes P011 and P061
Check with OCTOPUS!
Quality of data
Generally very good
Some questionable values
Depth below station depth (default value?)
A lot of CTD profiles had to be discarded (oxygen) in Diva products due to poor quality
First feedback was given in Juli Ongoing communication.
Default value=99? Prevent….

8. Diva products ”Old” version of Diva 6-year running mean (MSDF)
Ongoing project in OSPAR to look at the quality of the products (how well they represent data)
A lot of maps
unknown quality (very time consuming to check all)
Maps for all levels.

9. Future Automated file format checks upon delivery - SDC2
Reduce the number of Diva maps in next phase? To increase quality and have time to describe the response on different settings that can be used in Diva.
Suggestion for a reference group in each sea basin to follow work and give feedback to Regional coordinators.
Valid products for Chlorophyll (all data 0-10 m/surface layer)
Strongly support the idea of an automatic check when supplying data. Ambition; catch all Chl-a data.

10. Contaminants Same kind of file format errors Wrong primary variable
Missing columns in lines
Missmatch between header ans semantic header
Old vocabulary codes P011 and P061
QC; Negative values flagged
Minor part.
