Decades-Old WWII Ammunition Poses Growing threat to baltic Sea Ecosystem

A German pilot project is underway to remove explosive war waste from the Baltic Sea,as deteriorating munitions increasingly contaminate the water and pose explosion risks.
The Persistent Threat of Baltic Sea Munitions
The Baltic Sea floor holds a significant amount of unexploded ordnance (UXO) from World War II and subsequent conflicts.As these munitions corrode, they release harmful chemicals, contaminating the water and endangering marine life. The risk of accidental detonation also increases with time, posing a threat to shipping and coastal communities. This issue has persisted for decades, escalating the risk to both the ecosystem and human health.
Germany’s “Baltic Lift” Pilot Project
Germany is currently conducting a pilot project off the coast of Boltenhagen to safely remove and dispose of this perilous war waste. The operation,dubbed “Baltic Lift,” utilizes a specialized platform and divers working continuously to locate and collect rusty shells. As of the latest reports, approximately 900 tonnes of explosive war waste have been identified on the seabed in this area alone.Tagesschau reports on the ongoing efforts and challenges.
Detonation Risks and Environmental Contamination
“This ammunition not only contaminates water, but can also explode – detonators become extremely sensitive over time,” explained Dwirer Dirk Schoen, a participant in the operation, according to initial reports. The explosive compounds within the munitions, such as TNT and RDX, can leach into the water column, impacting marine organisms and possibly entering the food chain. Corrosion also releases heavy metals like lead and mercury, further exacerbating the environmental damage.
The Baltic Sea’s unique characteristics – low salinity, limited water exchange, and stratification – amplify the effects of pollution, making it particularly vulnerable to the long-term consequences of UXO contamination. The Helsinki Commission (HELCOM) provides comprehensive data on pollution trends in the Baltic Sea.
Scale of the Problem and Future efforts
Estimates of the total amount of UXO in the Baltic Sea vary widely, but experts believe it could be in the tens or even hundreds of thousands of tonnes. Beyond Germany,other Baltic sea nations – including Poland,Sweden,Finland,Latvia,Lithuania,Estonia,and russia – are also grappling with this legacy of war.
