1 SeaDataNet, Pan-European infrastructure for marine and ocean data management + EMODNET By Dick M.A. Schaap Technical Coordinator SeaDataNet & Coordinator EMODNet Bathymetry San Francisco USA, 13 December 2015, RCN meeting

2 EU MAST EU MASTII EU-FP5 EU-FP6 EU-FP7 90s EDMED Euronodim MEDATLAS EDIOS Sea-Search SeaDataNet SeaDataNet II SeaDataNet has set up and operates a pan-european infrastructure for managing marine and ocean data by connecting National Oceanographic Data Centres (NODCs) and oceanographic data focal points from 35 countries bordering European seas

3 Standards, services and tools! Set of common standards for metadata and data formats for the marine domain, adapting ISO and OGC standards and achieving INSPIRE compliance! Controlled vocabularies for the marine domain (> terms over > 60 lists)! Set of tools to be used by each data centre capacity building and standardisation! Pan-European services for discovery, access, visualisation and data products

4 Pan-European directory services

5 EDMO directory of marine organisations > 3000 organisations; also population by USA and Australia (ODIP)

6 CDI service for discovery and unified access of data Already 102 data centres connected

7 CDI Data Discovery & Access service December 2015: 102 data centres connected

8 CDI Data Discovery & Access service Coverage December 2015: > 1,8 million CDI entries from data centres in 34 countries and 550 originators for physics, chemistry, geology, geophysics, bathymetry and biology; years ; 84% unrestricted or under SeaDataNet licence

9 Core partner in developing and building: European Marine Observation and Data Network Phase 1 limited sea basins (ca 6 MEuro) Phase 2 - low resolution (ca 16 MEuro) Phase 3 - multi-resolution (> MEuro) PROTOTYPING: allows users to assess and improve product by trying it out Resulting in uptake of SeaDataNet standards and expansion of the infrastructure of data centres giving data overview and access

10 EMODnet Chemistry! EMODNet Chemistry project has a scope of chemical substances:! Pesticides and biocides! Antifoulants! Pharmaceuticals! Heavy metals! Hydrocarbons! Radionuclides! Fertilisers! Organic matter(e.g. from sewers or mariculture)! Chlorophyll! Partial pressures of dissolved gases! Acidity (from ph, pco2, Total Inorganic Carbon, alkalinity)! Others! Compiling data collections and interpolated maps for regional seas in support of the MSFD implementation

11 Chemistry CDI Data Discovery and Access Service! Dedicated CDI service for EMODNet Chemistry scope! Three search interfaces for human users, upgraded as part of the project:! Quick Search with dynamic drilling down of search results;! Extended Search with more flexibility for combining search options, including free search;! Variables Vs Marine Regions with an interactive Matrix of variables in specific marine regions.

14 Discovery and harvesting of data sets for regional product groups! EMODNet Chemistry 2 project is generating chemistry products per MSFD sea region! Discovery and harvesting of data sets per MSFD region for specific chemical parameters is done in an almost full automatic method by:! using a Robot harvester via the shopping mechanism to discover and retrieve specific data sets from distributed data centres! to compile and maintain specific aggregate data sets as internal central data buffers that are transferred to regional groups for further processing and products generation.

15 Buffer CMS + Central User Interfacing API CDI User Interfaces Robot CMS to configure Robot harvesting profiles MARIS master CDI Robot harvester Agreed Settings Dynamic Maintenance CDI User Interface + Shopper: Access regulated via AAA Specific data buffers RSM system extended with administering robot transactions and via central interfaces

16 Discovery and harvesting of data sets for regional product groups nutrients! Robot harvester has gathered circa CDI records and data sets for nutrients in the given regions These sets were transferred to the EMODNet regional groups per region

17 Quality assessment for data and products Questionnaire based on ISO/ IEC 17025: Data are checked, flagged and completed with metadata by National Collators Update the official copy of data data extraction Feedback loop guarantees data quality upgrade Regiona Regiona l l Regional data collections Report errors to the data originators Regiona Regiona QCd data l buffers l a collections - Data Aggregation - Parameter Homogenization - Unit Conversion (to «umol/ l») - Regional Quality Check - Global Analysis

18 EMODnet Chemistry advanced services DIVA + OceanBrowser service OpenEarth services QCd data buffers Regional experts ODV QC + aggregation CDI Robot Harvester Specific data buffers

19 Advanced services! The validated and aggregated buffers of data sets are input for the products and advanced services:! Interpolated maps as produced with DIVA software! Time series graphics for all collected data sets via WPS! OceanBrowser viewer as common service for viewing the DIVA maps and giving access to the time series graphics! Sextant catalogue to document all products with metadata

20 OceanBrowser: Concentration maps of phosphate in spring per 10 years as animations

21 Spatial distribution and density by GeoServer layers in OceanBrowser l Combination of WPS/WMS l Density indicated by colours

22 Spatial distribution and density: plots of profiles and timeseries per station

23 EMODNet Bathymetry! Overall objective: to bring together bathymetric surveys of European seas and to produce, publish and serve a harmonised and medium resolution Digital Terrain Model of all European seas! > surveys indexed! DTM for all European seas at 1/8*1/8 arc minutes (~230 m)! DTM uses > survey data sets and composite DTMs from 31 data providers from 18 countries and GEBCO_2015! DTM contains data points ( rows x columns)! 3 high resolution coastal areas! Latest release: 8 Sept 2015

24 DTM for European sea basins

25 DTM for European sea basins
