🔗 Share this article World War II Explosives, Torpedoes and Mines: How Marine Life Thrives on Dumped Armaments In the slightly salty waters off the Germany's coast lies a graveyard of Nazi bombs, torpedo heads and mines. Thrown off barges at the end of the second world war and forgotten about, numerous munitions have fused into clusters over the decades. They comprise a corroding layer on the low-depth, muddy seafloor of the Bay of Lübeck in the western tip of the Baltic. Over the years, the Nazi arsenal was overlooked and forgotten about. A increasing amount of visitors flocked to the coastal areas and calm waters for jetskiing, kiteboarding and amusement parks. Underwater, the munitions deteriorated. Some of us thought to see a barren area, with no life because it was all toxic, states a scientist. When the initial researchers went investigating to see what they were doing to the marine environment, researchers thought they would find a lifeless zone, with nothing living there because it was all poisoned, says a scientist. What they discovered surprised them. Vedenin remembers his scientists reacting with shock when the ROV first sent the images back. This was a memorable occasion, he says. Thousands of ocean life had established habitats amid the munitions, developing a revitalized habitat richer than the ocean bottom surrounding it. This marine city was proof to the persistence of marine life. It is actually surprising how much marine organisms we observe in areas that are considered dangerous and risky, he says. In excess of 40 starfish had piled on to one exposed piece of TNT. They were living on iron containers, ignition chambers and carrying containers just centimetres from its volatile core. Fish, crabs, anemones and mussels were all observed on the historic weapons. It's similar to a marine reef in terms of the quantity of creatures that was present, notes Vedenin. Unexpected Creature Concentration An average of more than forty thousand creatures were living on every meter squared of the munitions, scientists documented in their paper on the finding. The adjacent region was much sparser, with only 8,000 organisms on every meter squared. It is surprising that objects that are designed to destroy everything are attracting so much life, says Vedenin. It's evident how nature adapts after a major disaster such as the second world war and how, in some way, life returns to the most risky locations. Artificial Structures as Ocean Environments Artificial features such as sunken vessels, offshore windfarms, drilling platforms and undersea pipes can create replacements, replacing some of the destroyed marine environment. This research reveals that explosives could be equally positive – the explosion of life on those in the Bay of Lübeck is probable to be duplicated in different areas. Between the late 1940s and the post-war period, 1.6m tonnes of munitions were discarded off the Germany's coast. Countless of individuals transported them in barges; some were placed in designated locations, others just dumped while traveling. This is the first time scientists have recorded how ocean organisms has responded. Worldwide Instances of Marine Adaptation In the US, decommissioned drilling platforms have become reef ecosystems Sunken ships from the World War I have become habitats for marine life along the Potomac in the state of Maryland Tank tracks that have become home to coral off Asan in Guam These locations become even more crucial for organisms as the seas are increasingly depleted by fishing, seafloor dredging and anchoring. Sunken ships and weapons dump sites effectively function as refuges – they are not official reserves, but virtually any kind of human activity is restricted, explains Vedenin. As a result a lot of organisms that are typically scarce or diminishing, such as the Baltic cod, are prospering. Coming Issues Wherever military conflict has taken place in the last century, surrounding seas are usually containing munitions, says Vedenin. Many millions of tonnes of volatile compounds lie in our oceans. The sites of these weapons are insufficiently recorded, partly because of national borders, classified defense data and the situation that documents are hidden in historic archives. They present an explosion and safety danger, as well as threat from the ongoing leakage of toxic chemicals. As the German government and different states embark on extracting these relics, scientists plan to protect the habitats that have formed in their vicinity. In the Lübeck Bay munitions are already being cleared. It would be wise to substitute these metal carcasses remaining from weapons with certain more secure, some harmless structures, like maybe artificial reefs, says Vedenin. He currently aspires that what transpires in the Bay of Lübeck establishes a model for replacing structures after munitions removal in other locations – because including the most destructive armaments can become foundation for new life.
