EMODnet Chemistry WP 1 Data collection and metadata

EMODnet Chemistry WP 1: Data collection and metadata compilation in sea regions: current status Partner contribution: Institute of Marine Research, Norway Annual Meeting, June 15 -16 2015, Istanbul, Turkey

Current status General overview of the partner contribution: Seawater Sediment Biota 0 0 0 Number of CDIs at year 1: 14137 0 0 Number of CDIs at year 2: 30895 0 0 Number of CDIs at beginning: Spatial distribution: Annual Meeting, June 15 -16 2015, Istanbul, Turkey

Current status Total number of stations per parameter group per matrix: Group Seawater Fertilizers 30895 Silicates Sediment 30828 Organic matter Chlorophyll Partial pressure dissolved gases 18153 5916 Acidity Pesticides and biocides Antifoulants Pharmaceuticals Heavy metals Hydrocarbons Radionuclides Plastics Annual Meeting, June 15 -16 2015, Istanbul, Turkey Biota

Data quality control performed by the data center: Type of QC: Seawater Sediment Biota Position check X X X Date check X X X Missing value X X X Range check X X X Biota, sediment: only radionuclides Spike X X X Biota, sediment: only radionuclides X X X Correlation of results within sample X X Pesticides, hydrocarbons, PCB Certified reference material X X Pesticides, hydrocarbons, PCB In house reference material X X Pesticides, hydrocarbons, PCB Proficiency testing scheme X X Pesticides, hydrocarbons, PCB Notes: Pre-existing statistics Visualization and manual checks Others: Annual Meeting, June 15 -16 2015, Istanbul, Turkey

Difficulties encountered: • Data in many different formats (Excel files), takes time to restructure the data • The chemistry data has not been available to others before, researchers concerned that data can be misused • Radionuclides in biota: Data can be based on samples from more than one station – which position should be used? • ODV format: Not possible to use platform code Annual Meeting, June 15 -16 2015, Istanbul, Turkey

Planning for the last year Total number of stations per parameter group per matrix: Group Seawater (X) (X) X X 3000 Silicates Biota (X) Fertilizers Sediment 3000 Organic matter Chlorophyll 3000 Partial pressure dissolved gases Acidity Pesticides and biocides Antifoulants Pharmaceuticals Heavy metals Hydrocarbons Radionuclides X Plastics Annual Meeting, June 15 -16 2015, Istanbul, Turkey
