Data collection and metadata population – harvesting EMODnet Chemistry 3 – Plenary Group meeting – Madrid, Spain 29 January 2019) Dick M.A. Schaap dick@maris.nl MARIS

Approach for chemistry data gathering Continuation of approach of gathering and populating relevant measurements data into the SeaDataNet CDI Data Discovery and Access service with CDI metadata format and ODV data format; use of MIKADO, NEMO and OCTOPUS tools Focus on data concerning: Eutrophication (nutrients, chlorophyll and oxygen) Contaminants Marine micro litter Geographical scope expanded with Barents Sea Data scope expanded with riverine input of nutrients Also metadata and data collected for beach litter and seafloor litter via other approach 2

CDI entry activity All data centres in the EMODnet Chemistry consortium have undertaken activities for extra population! However not all data centres have enriched (a subset) of their existing CDIs with information about projects and data quality control (see guideline: http://nodc.ogs.trieste.it/doi/documents/Updated-Guidelines- CDI_EMODnetChemistry3.pdf Example of CDI record: http://emodnet- chemistry.maris2.nl/v_cdi_v3/print_ajax.asp?n_code=2498459 Quality Info included by only: BODC, CNR-ISMAR, IHPT, and RBINS EDMERP relations included by most data centres for subsets 11

Harvesting of CDI’s Harvesting of Eutrophication and Contaminants regional data collections has taken place using the CDI Buffer system For the defined MSFD regions Arctic ocean - Barents sea - Norwegian sea – Greenland sea - Icelandic waters Greater North Sea - Celtic Sea – Faroes Baltic Sea Iberian peninsula - Macronesia - Bay of Biscay Mediterranean Sea Black Sea - Sea of Marmara - Sea of Azov 14

Harvesting and processing Eutrophication harvest: November – December 2017 Contaminants harvest: October 2018 Regional harmonised and validated Eutrophication data collections delivered by Regional Coordinators at: May 2018 Also described in Sextant and with DOIs Regional harmonised and validated Contaminants data collections delivered by Regional Coordinators at: January 2019 Not yet described in Sextant and no DOIs yet 16
