How alarming are the ammunition remnants of two world wars still lying in old wrecks at the bottom of the North Sea and other seas? The EU-funded international project "North Sea Wrecks" investigated these questions, diving to wrecks in the North Sea, taking samples and analysing them. In a symposium on 19 and 20 April 2023 at the Alfred Wegener Institute, the project partners now presented the results. For more information, see this press release from the German Maritime Museum (DSM), which led the project.
