An international team of scientists working on the multi-year research project ‘Towards the Monitoring of Dumped Munitions Threat’ (MODUM), supported by NATO’s Science for Peace and Security (SPS) Programme have been mapping the ocean floor, locating and monitoring munition dump sites in the Baltic Sea. The variety of chemical weapons and explosives left over from the Second World War is thought to pose a significant threat to marine life in the region.

Footage includes interviews with key scientists and mission personnel, archive material of the underwater dump sites and operations on board a Polish research vessel.
