Including:
Pressure profiles
Profiles with min and max depth (average)
About restricted profiles
Annual meeting, Roskilde 6-7 February 2018

4. ODV files - issues Crucial Mismatch between header and semantic header
Missing parameters in header
Missing tabs in line (line is discarded)
We are getting better!
Not crucial
Old labels: P011, P061
Parameter names
Empty columns
Missing quality flag for Depth
Incorrect primary variable
LOCAL_CDI_ID duplicates
Annual meeting, Roskilde 6-7 February 2018

5. Thoughts, ideas and questions
How to handle (integrated) chlorophyll?
Also in EMODnet Biology
Often represented with min and max depth (integrated) .
Included in main collection by taking the average depth
Suggestion to make Diva-product with all data between 0-10 meters (set depth to 0).
NO3 or NO2+NO3?
NO3 is expected to be NO2+NO3 if NO2 is not present
This should be clearer
It’s preferable to include salinity and temperature in the ODV files.
6-year average for Diva products (MSFD)
Will the coverage be enough?
