For next year
- Temporal series: focus on sediment, Update for existing CDIs
- New cruises collected by SISMER (PELGAS 2004 – 2011)
- Finalize CDIs integration and data QC for partners
- Products generation

• Deletion of empty stations (No measurements on all levels for the parameter)
• Deletion of empty lines in a station : some levels with no measurements for the parameter
• Search for duplicates (linked to the 2 distinct datasets)
• QC using ODV– Search for out of range values with Flag = 1– Set a QC for all measurements with Flag=0– Set default values with Flag=0 or Flag=1 to
Flag=9• Write a report on QC and send results to data

• Data coverage: for Ammonium, Silicate, Nitrate– What is a « reasonable » coverage for a product?– How to make the mask? New topography or
masked area?
• Data with QF=6 (value below detection): how to deel with?
– put value to limit– put value to 0
• How to deal with estuaries?
DIVA PRODUCTS – PROBLEMS FACED
