As part of the DArgo2025 project, Germany’s Federal Maritime and Hydrographic Agency (BSH) coordinated the successful validation and deployment of new sensors on automated drifting buoys, so-called Argo floats. These sensors can now be deployed worldwide and thus provide information about current environmental changes in the oceans, such as increasing eutrophication, oxygen depletion, and acidification. In this context, the IOW evaluated novel nutrient sensors that were tested in the Baltic Sea. The project, which ended in December 2021, was funded by the Federal Ministry of Education and Research.
