Decision Aid for marine munitions – towards knowledge based management Jacek Bełdowski
Situation of Baltic Sea dumped munitions
Chemical munitions sunk at sea • 40 000 tonnes sunk in Baltic proper, 150 000 tonnes in Skagerrak • Natural processes plus enhancing human pressure put environment at risk
Legend: CWA Dumps Dredge sites Offshore wind farms (planned) Bottom Trawling intensity Pipelines and Cables
