As of March 2022 the project has reached the half-way milestone. A good opportunity to reflect back on the multiple achievements within the first year and a half as partners make substantial progress towards sharing and harmonizing data on the Baltic Sea marine environment. These include the update of the HELCOM Metadata Catalogue, launch of the LATMARE marine monitoring database, development of project KPIs, further development of the hazardous substances online assessment tool (CHASE), and more. The project is on track to meet all project milestones and tasks.
