About ShipNoDeff

ShipNODeff is a Research and Technological Development program for the estimation of the ship nitrogen emissions and their effects to the eutrophication of the Baltic Sea.


The atmospheric deposition of nitrogen is found to have a major effect on the Baltic Sea ecosystem. About 25-30 % of the nitrogen entered the Baltic Sea as airborne input.
