🔗 Share this article Nazi Explosives, Torpedoes and Mines: How Marine Life Prosper on Discarded Armaments In the slightly salty waters off the Germany's shoreline lies a collection of Nazi bombs, torpedoes and mines. Dumped from boats at the conclusion of the second world war and forgotten about, thousands weapons have fused into clusters over the years. They create a corroding carpet on the shallow, muddy ocean floor of the Lübeck Bay in the western tip of the Baltic Sea. Over the decades, the Nazi arsenal was overlooked and neglected. A growing number of visitors came to the sandy beaches and tranquil sea for jetskiing, kite surfing and entertainment venues. Beneath the surface, the weapons eroded. We initially anticipated to see a lifeless zone, with no organisms because it was all contaminated, states a scientist. When the team went looking to see what they were affecting to the marine environment, some of us thought they would find a lifeless zone, with no life because it was all toxic, states the lead researcher. What they found amazed them. Vedenin recalls his team members shouting with surprise when the underwater vehicle first transmitted footage. It was a great moment, he notes. Countless of marine animals had established habitats on the weapons, forming a renewed ecosystem richer than the ocean bottom around it. This underwater metropolis was proof to the persistence of marine life. Indeed remarkable how much marine organisms we find in locations that are expected to be toxic and harmful, he explains. Over 40 starfish had piled on to one visible fragment of TNT. They were dwelling on iron containers, fuse pockets and carrying containers just a short distance from its explosive filling. Marine fish, crustaceans, sea anemones and bivalves were all discovered on the old munitions. You could compare it with a coral reef in terms of the quantity of animal life that was inhabiting the area, says Vedenin. Surprising Population Density An mean of more than 40,000 creatures were residing on every square metre of the explosives, experts reported in their research on the finding. The adjacent region was much less diverse, with only 8,000 individuals on every meter squared. It is paradoxical that items that are intended to kill all life are attracting so much marine organisms, says Vedenin. One can observe how the natural world adapts after a catastrophic event such as the second world war and how, in certain respects, marine life finds its way to the most dangerous locations. Artificial Features as Marine Environments Man-made structures such as shipwrecks, wind turbines, oil rigs and pipelines can create alternatives, compensating for some of the lost habitat. This research reveals that weapons could be comparably advantageous – the bloom of life on those in the Bay of Lübeck is probable to be repeated in other locations. Between the late 1940s and the post-war period, 1.6 million tons of arms were disposed of off the German coast. Countless of workers placed them in boats; some were dropped in specific locations, others just discarded at sea while traveling. This is the initial instance scientists have recorded how marine life has adapted. Worldwide Examples of Ocean Transformation In the United States, decommissioned drilling platforms have turned into reef ecosystems Sunken ships from the first world war have become homes for creatures along the Potomac in Maryland Military vehicle parts that have become habitat to coral off Asan beach in the Pacific island These places become even more crucial for marine life as the seas are increasingly stripped by commercial fishing, bottom trawling and boat mooring. Sunken ships and munitions areas effectively act as sanctuaries – they are not national parks, but virtually any kind of human activity is prohibited, explains Vedenin. As a result a numerous of species that are usually scarce or declining, such as the cod fish, are thriving. Future Factors Wherever armed conflict has taken place in the past 100 years, nearby oceans are often littered with explosives, explains Vedenin. Many millions of tonnes of volatile compounds remain in our seas. The positions of these munitions are insufficiently mapped, in part because of national borders, classified military information and the fact that documents are buried in historical records. They present an detonation and security risk, as well as risk from the persistent leakage of toxic chemicals. As the German government and additional nations embark on removing these relics, researchers aim to safeguard the marine communities that have developed in their vicinity. In the Bay of Lübeck munitions are currently being cleared. We should substitute these metal carcasses remaining from munitions with certain more secure, some harmless structures, like maybe man-made habitats, says Vedenin. He now hopes that what occurs in Lübeck creates a example for substituting structures after weapon clearance in other locations – because also the most damaging armaments can become scaffolding for new life.
