This challenge handled the ability to compute the seasonal averages and changes of eutrophication in the basin over past 10 years (i.e. for reduction or increase),  to assess whether the current available marine data sets are available and appropriate to the use case, as well as to indicate gaps in the current EU data collection framework.


The eutrophication challenge attempted to produce seasonal averages and changes of eutrophication in the basin:

  • Seasonal averages of eutrophication for the past ten years
  • Change in eutrophication over the past ten years (i.e. where eutrophication has reduced and where it has increased).

Access to challenge products

Seven products are made available by CEFAS and ACRI-HE for the Eutrophication challenge as the result of the assessment exercise carried out for the EU Atlantic checkpoint project (DG MARE contract, 2015-2018). The products are listed and accessible from the table given below. All products are representative of June 2017 status. There is no vertical dimension.

The challenge partners ("the producers") were commissioned to perform a number of tests to evaluate marine data according to set user requirements. The table below enables:

  • to discover :
    - the Data Product Specifications (DPS) which describe data products in terms of user requirements according to ISO19131 principles and provide the basis for the quantitative assessment of the Products (Quality measures and scope of application)  and of the Upstream Data sets supplied to- and used by- the challenges to create them.
    - the Results (TDP) which describe the Data Product created together with the quantitative assessments (Quality measures and indicators) and the expert opinion.
  • to download the products (shapefile, excel, pdf) on an "as is" basis. All downloads suppose acceptance of the use limitations described in the “Expert opinion” and the “Legal constraints” accessible using the  link to the Results.
  • to view the spatial data products (Maps) using a webGIS.

    Data product were scored by experts from 1 to 5, resp. inadequate to excellent. The score is mentioned in the last column. “Good” means the Product was achieved to at least 50% of the requirements. “Inadequate” means “Impossible to produce or fails to meet all the objectives (not usable)”.
