Eutrophication - the over-enrichment of water by nutrients such as nitrogen and phosphorus - remains critical in the North-East Atlantic Ocean and the Baltic Sea, as clearly stated in the latest assessment reports by HELCOM and OSPAR. In order to help fulfil commitments towards a healthy sea, CodeBlue will provide robust, coherent, transparent and directly applicable modeling data sets for the development of Digital Twins of the Baltic Sea and Noeth-East Atlantic. The development work is done through two-way communication with stakeholders, aiming toward outputs to be used in marine management as well as sustainable blue economy entrepeneurs. The Archipelago Sea in South-West Finland is one of the case study areas. Eutrophication scenarios will be developed to support the nationa Archipelago Sea Programme, which aims at improving the eutrophication status of this area so that it can eventually be removed from the HELCOM list of eutrophication Hot Spots.
