Short summary
In this study, we used the MESAW statistical model to estimate the surface water N retention. Such large-scale estimates are lacking for the Baltic Sea and there are only a few studies of this globally. Our results show that around 380 000t of N are annually retained in surface waters draining to the Baltic Sea. The total annual riverine load from the 117 basins to the Baltic Sea was estimated at 570 000t of N, yielding a total surface water N retention of around 40%.
