The “alien species” challenge aims to identify alien species in the sea basin.
The identification information should include:
- Species name
- Family (fish, algae, mammals, sponges etc)
- Year of introduction
- Reason for introduction (climate change, ballast water discharge etc)
- Geographical area
- Impact on ecosystem
- Impact on economy
Up to ten indicators should be used to determine impacts on ecosystem and economy. These could, for instance, include extinction of native species, reduced income for fishermen, risk to aquaculture.
The workflow is made of three major activities:
Activity 1: to search for upstream data to meet challenge requirements
- Mnemiopsis leidyi, Beroe ovata, Rapana venoisa
- Phytoplankton and zooplankton alien species
- Maritime traffic and other human activity spatial distribution(ballast water and hull fouling)
Activity 2: to build and analyze data base, produce challenge outputs for GIS use
Activity 3: to deliver checkpoint information, and report assessment in results in the Literature Survey and Data Adequacy Reports.

- Which input information is looked for, discoverable ?
- Data collection programs: National Databases, International Databases
- The different environmental matrix involved (Marine water)
- Are data sets accessible ?
The Challenge will provide information on the data availability in a standardized way plus terms of access and use.
- How appropriate for use are the data ?
The Challenge will provide information on the data appropriateness in standardized way plus descriptive text of strengths and weakness regarding the appropriateness of upstream data used. It will include a rationale for non selection of unused input data.
