EMODnet Chemistry 2 Service Contract MARE/2012/10 S 12. 656742 How to make EMODnet Chemistry fit for purpose at system level By Dick M. A. Schaap – Technical Coordinator Oostende - Belgium, 21 October 2015, 2 nd Experts Workshop
EMODNet Chemistry portal The EMODNet Chemistry portal sits on top of the Sea. Data. Net infrastructure and makes use of its services that have been adapted and are further developed for specific EMODNet Chemistry needs. It provides various services and functionalities to users for browsing and viewing the chemistry data products and for identifying and requesting access to the gathered chemistry data sets for the European waters. The primary services are: CDI Data Discovery and Access Service giving facilities for searching and retrieving chemistry data sets; Ocean. Browser Viewing Service giving facilities for viewing, browsing and downloading Chemistry data products; Sextant Products metadata catalogue giving facilities for searching Chemistry data products and linking to the viewing service.

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.
Buffer CMS + Central User Interfacing API Robot CMS to configure Robot harvesting profiles MARIS master CDI User CDI Robot Interfaces harvester Agreed Settings CDI User Interface + Shopper: Access regulated via AAA Dynamic Maintenance Specific data buffers RSM system extended with administering robot transactions and via central interfaces
Central User Interface with logon (AAA service) following authorisation in buffer CMS profiles logon Overview of authorized buffers Central buffer UI incl direct shopping
Discovery and harvesting of data sets for regional product groups – nutrients Robot harvester has gathered circa 480. 000 CDI records and data sets for nutrients in the given regions These sets were transferred to the EMODNet regional groups per region
Discovery and harvesting of data sets for regional product groups The new Buffer CMS and robot harvesting greatly facilitate the maintenance of central buffers. A Central buffer User Interface and API (for full machine-to-machine interaction) facilitates regular delivery of data sets incl metadata to the Chemistry regional groups. The central buffers contain ‘raw’ data sets for specific parameters and as harvested from the distributed data centres. Aggregation and validation for generating homogeneous data collections is done by using ODV software. P 35 vocabulary and specific expertise per region and chemical substance The final buffers of aggregated and validated data sets provide the input for data products and advanced visualisation services

Making data collections available for MSFD The validated and aggregated buffers of data sets incl metadata are used for: Interpolated maps as produced with DIVA software Plots for selected stations via WPS With Ocean. Browser viewer as common service The DIVA maps are freely available for viewing and downloading The validated data collections could be of relevance for MSFD bodies. In that case needed: regulated access mechanism with UI and API version management of data collections Maintenance by means of new versions in time
