    A specific marine biological data management tool, the Black Sea Mnemiopsis leidyi database system was created within the European Commission 6th framework Black Sea SCENE project fo r the Black Sea region and is now being supported by the Permanent Secretariat of the Black Sea Commission. The core team of scientists studying M. leidyi in the Black Sea was brought together and all their available M. leidyi data and metadata were loaded into the common database. This works on the Internet and has a simple user interface. It gives Black Sea scientists the option to load all their corresponding data on the database and to use it as an effective tool to work both with M. leidyi and, in future, with other gelatinous organisms’ data, including another invasive ctenophore Beroe ovata . All loaded metadata and historical data are available to the entire scie ntific community. More recent data are available to the team members and with some restrictions – to other scientists.

    Data towards assessing non-indigenous species introductions in the Black Sea
    (Elsevier Sci Ltd, 2025) Magliozzi, Chiara; Cardoso, Ana Cristina; Son, Mikhail O.; Kvach, Yuriy; Japoshvili, Bella; Stefanova, Kremena; Kurt, Guley
    The Marine Strategy Framework Directive (MSFD, 2008/56/EC) sets the foundation for community actions in the field of marine environmental protection and a robust and collaborative assessment of the implementation of measures by Member States (MS) of the European Union. In particular, the Commission Decision (EU) 2017/848 lays down criteria and methodological standards on good environmental status (GES) for assessing nonindigenous species (NIS) pressure in marine waters. One of these criteria (i.e. D2C1) aims to minimise and where possible reduce to zero, the number of NIS newly introduced into Europe's marine waters. To this end, the need for up-to-date data on newly introduced NIS is paramount to enable a quantitative assessment of D2C1. This paper provides a summary of the latest developments on the methodologies for assessing D2C1 and their application on the Black Sea dataset. The analysis identifies common practices and needs; strengthening NIS monitoring would improve the confidence of NIS assessment and allow for investigation of changes in NIS spread, ecological impact and effectiveness of management action. Additional efforts should also be made to ensure access to the monitoring results.
