2. EMODnet Chemistry Updates on the Baltic dataset
CDIs ( , 45%)
Most of the errors are still there:
Position (0,0)
Mismatch between header and semantic header
Bad profiles
This is due to:
Originators have not changed there ODV files
Originators have changed their ODV files but have not sent new CDIs to MARIS.
No major progress despite a lot of time being spent
Delay in data delivery
Problems in ODV
Steering Committee Meeting, Dec , Amsterdam, Netherlands 2

3. EMODnet Chemistry Problems to discuss
We believe value=0 with QF=1,2 and 6 should be left alone
Make no difference
QF-scheme will change
A lot of work to change values
Originators should be encouraged to change their data
Option to implement “no value under zero” in DIVA?
Aggregating to NOX
When aggregating QF-scheme will be changed and we loose QF=6
Adding NO3 and NO2 with one QF=6 is a bit confusing.
No problem in DIVA products (it should be clear that data includes QF=6)
The dataset that we will provide should NOT include aggregated NOX

4. EMODnet Chemistry Problems to discuss
To many DIVA-products
Huge amount of data capacity
Time consuming
Not representative as a climatology at all depths
Suggestion is to have 40 periods for a few parameters and 1-2 depths and a couple of seasons, and make 2-3 periods for the rest.
Data harvesting
Originators have updated their ODV files but not their CDIs.
Might it be an option to harvest ALL data for the final run?

5. EMODnet Chemistry Problems to discuss
DIVA
Be careful with new ODV-format that include several “depth”-parameters. DIVA uses the first match AFTER “Bot. Depth”. Change name of the other “depth”-parameters to be safe.
ODV
Problems with analysis.log and import.log during SDN import
Problems with logfile / historypool during QC
