🔗 Share this article World War II Bombs, Torpedoes and Naval Mines: How Ocean Creatures Prosper on Abandoned Weapons In the brackish sea off the German coast sits a wasteland of World War II explosives, torpedoes and naval mines. Dumped from boats at the end of the second world war and left behind, countless munitions have fused into clusters over the decades. They create a corroding carpet on the shallow, muddy ocean floor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the Nazi arsenal was ignored and forgotten about. A growing number of tourists traveled to the sandy beaches and tranquil sea for jetskiing, kiteboarding and entertainment venues. Below the waves, the munitions deteriorated. Some of us expected to see a desert, with no life because it was all toxic, explains the lead researcher. When the first scientists went looking to see what they were doing to the ecosystem, the team anticipated finding a desert, with nothing living there because it was all poisoned, explains Andrey Vedenin. What they discovered amazed them. Vedenin remembers his team members shouting with surprise when the underwater vehicle first transmitted footage. It was a memorable occasion, he says. Countless of sea creatures had established habitats on the weapons, developing a regenerated habitat denser than the sea floor around it. This underwater metropolis was testament to the tenacity of marine life. Truly remarkable how much life we observe in locations that are expected to be hazardous and risky, he explains. Over 40 sea stars had piled on to one visible piece of explosive material. They were living on metal shells, fuse pockets and storage boxes just centimetres from its dangerous content. Fish, crustaceans, anemones and mussels were all observed on the discarded explosives. It's similar to a marine reef in terms of the abundance of animal life that was present, says Vedenin. Unexpected Population Density An mean of more than 40,000 organisms were dwelling on every square metre of the explosives, scientists documented in their research on the discovery. The nearby seabed was much sparser, with only eight thousand individuals on every square metre. It is ironic that objects that are intended to eliminate all life are drawing so much life, says Vedenin. It's evident how nature adapts after a major disaster such as the World War II and how, in certain respects, marine life returns to the most hazardous locations. Artificial Structures as Marine Habitats Artificial features such as sunken vessels, offshore windfarms, oil rigs and pipelines can create replacements, replacing some of the lost marine environment. This study shows that weapons could be comparably beneficial – the explosion of life on those in the Bay of Lübeck is likely to be found elsewhere. Between the late 1940s and the post-war period, 1.6 million tonnes of munitions were disposed of off the Germany's shoreline. Countless of workers transported them in boats; some were dropped in specific locations, others just dumped en route. This is the first time experts have recorded how ocean organisms has reacted. Worldwide Instances of Ocean Transformation In the United States, decommissioned drilling platforms have transformed into reef ecosystems Submerged vessels from the first world war have become environments for creatures along the Potomac River in Maryland Military vehicle parts that have become home to coral off Asan beach in the Pacific island These locations become even more crucial for marine life as the oceans are increasingly denuded by fishing, seafloor dredging and boat mooring. Shipwrecks and munitions areas effectively function as refuges – they are not official reserves, but almost any kind of human activity is prohibited, explains Vedenin. As a result a numerous of marine species that are typically uncommon or decreasing, such as the cod fish, are flourishing. Future Considerations Anywhere armed conflict has taken place in the past 100 years, nearby oceans are often containing weapons, states Vedenin. Many millions of tonnes of volatile compounds rest in our seas. The sites of these munitions are insufficiently documented, in part because of national borders, classified defense data and the situation that records are buried in old files. They present an detonation and safety hazard, as well as danger from the persistent leakage of toxic chemicals. As the German government and additional nations begin clearing these remains, experts plan to safeguard the ecosystems that have formed around them. In the Bay of Lübeck explosives are presently being cleared. We should substitute these steel remains left from weapons with some more secure, some harmless materials, like possibly man-made habitats, says Vedenin. He now hopes that what transpires in the Bay of Lübeck establishes a example for replacing structures after munitions removal in different areas – because also the most destructive armaments can become framework for new life.
