Our initial idea for the SEABASED project was to tackle the challenges related to internal nutrient loading in the Baltic Sea. We aimed at creating a project that in the end would provide, also some practical solutions for cutting down the eutrophication of the sea. However, when preparing the project, we found out that actually very little coherent information exists about the so call sea-based measures, and a bunch of novel and innovative ideas around them. Based on discussions with a number of stakeholders, presenting very different viewpoints and perspective, we have given our best shot to identify the most potential ideas to pilot and to learn more. What this will amount to, we now believe, is building up a fruitful dialogue between a number of stakeholders over the coming 30 months and, hopefully, finding sustainable solutions for helping the sea.
