Annual Meeting, June , Istanbul, Turkey Difficulties encountered: Chokepoint 1. Matching «parameter/dimension/environment» to P01 Chokepoint 2. Matching «devices» to L05 Chokepoint 3. Determining the EDMO «originator» Example from the curation of heavy metals: events available for dissemination to SDN / EMODnet events could be matched to P01 & L events were attributed an EDMO «originator» Only 9% of available data is delivered to SDN / EMODnet

Annual Meeting, June , Istanbul, Turkey Difficulties encountered: Chokepoint 1. Matching «parameter/dimension/environment» to P01 Chokepoint 2. Matching «devices» to L05 Chokepoint 3. Determining EDMO «originator» Chokepoint 1 & 2: 75% loss Difficulties with matching P01 & L05 for «heavy metals» in biota, ice, consolidated sediments and air Recommendation: Allow decatenated parameters so that we can describe separately «what», «units», «environment 1 » and «method» 1 e.g. water body, sediment, biota, air, etc.

Annual Meeting, June , Istanbul, Turkey Difficulties encountered: Chokepoint 1. Matching «parameter/dimension/environment» to P01 Chokepoint 2. Matching «devices» to L05 Chokepoint 3. Determining EDMO «originator» Chokepoint 3: further 67% loss PANGAEA’s originators are multiple authors with multiple affiliations We had to determine the «originator» based on the platform Recommendation: Allow citations (DOIs) as «originator»
