Short summary

We applied a 3D ecosystem model to the Oder Lagoon in the Baltic Sea and found that 40% of nitrogen and 12% of phosphorus are retained in the lagoon before entering the Baltic Sea. This is important for coarse-grained models that do not resolve such coastal structures. Moreover, the coastal filter supports the mitigation of eutrophication in the Baltic Sea.
