The media reports that in February 1945, the British torpedoed a German submarine that had broken in half after the impact. The U864 was traveling to Japan to supply Hitler's allies with strategically important raw materials, including mercury, which is essential for weapons production.
Since that time, the debris is about 150 meters deep near the port city of Bergen in southwestern Norway and was only discovered by fishermen in 2003.
Explorations carried out by submarine robots in 2005 showed that the seabed around the wreck was contaminated with mercury on nearly five hectares.
Approximately 47,000 square meters of seabed will need to be covered with a sarcophagus to prevent further contamination. The end of the works is planned for 2020 and the project is estimated at around 31.5 million euros.
This project, however, provoked opposition from the local population and environmental organizations who question the effectiveness of the sarcophagus and call to bail out the submarine and recover the mercury.
