How to make EMODnet Chemistry fit for purpose at system level

ByDick M.A. Schaap – Technical Coordinator

Oostende - Belgium, 21 October 2015, 2nd Experts Workshop

EMODNet Chemistry portal

The EMODNet Chemistry portal sits on top of the SeaDataNet 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; OceanBrowser 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.

CDI service for discovery and unified access of data

Already 102 data centres connected

Chemistry CDI Data Discovery and Access Service

Dedicated CDI service for EMODNet Chemistry scope Three search interfaces for human users:

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.

Getcapabilites indicates what is available. In CDI case it is both WMS and WFS. Implementing WFS is depending on the client and needs programming. We provide WFS request through WMS:

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.

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

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. P35 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 OceanBrowser 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 APIversion management of data collectionsMaintenance by means of new versions in time
