Alien Species


This challenge handled the ability to identify & source alien species in the sea basin, as well as any adverse impacts on ecosystems and socio-economy, as established by the ballast water management convention, 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  EU data collection framework.


The Alien Species challenge attempted to identify alien species in the North Atlantic as follows:

  • Species name
  • Taxonomic group
  • Year of introduction and citation
  • Vetors of introduction
  • Geographical distribution
  • Impact on ecosystem*
  • Impact on socio-economy*

* Criteria and methodological standards are established by COMMISSION DECISION (EU) 2017/848 (Official Journal of the European Union 18.5.2017L 125/50-51) on good environmental status (GES) of marine waters and specifications and standardised methods for monitoring and assessment (repealing Decision 2010/477/EU)

Access to challenge products

Three products are made available by AZTI for the Fishery Management 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 the June 2017 status. There is no dimension other than the temporal one.

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)”.
