🔗 Share this article World War II Munitions, Torpedo Heads and Naval Mines: The Way Marine Life Prosper on Dumped Armaments In the brackish sea off the German shoreline rests a graveyard of Nazi bombs, torpedoes and mines. Discarded from vessels at the conclusion of the World War II and left behind, thousands weapons have become matted together over the decades. They comprise a corroding layer on the shallow, muddy seafloor of the Bay of Lübeck in the western tip of the Baltic. Over the decades, the wartime weapons was overlooked and forgotten about. A growing number of tourists came to the sandy beaches and calm waters for jetskiing, kiteboarding and entertainment venues. Underwater, the munitions deteriorated. We initially expected to see a lifeless zone, with nothing living there because it was all contaminated, says Andrey Vedenin. When the initial researchers went investigating to see what they were affecting to the marine environment, the team expected to see a barren area, with no life because it was all contaminated, says the lead researcher. What they discovered amazed them. Vedenin recounts his team members exclaiming in amazement when the ROV first transmitted footage. This was a remarkable experience, he says. Numerous of sea creatures had established habitats on the weapons, creating a renewed habitat richer than the ocean bottom nearby. This marine city was proof to the resilience of marine life. Truly surprising how much life we find in places that are supposed to be dangerous and dangerous, he states. More than 40 sea stars had piled on to one exposed chunk of TNT. They were residing on steel casings, ignition chambers and transport cases just centimetres from its dangerous content. Fish, crabs, anemones and bivalves were all observed on the discarded explosives. You could compare it with a coral reef in terms of the quantity of fauna that was inhabiting the area, states Vedenin. Surprising Creature Concentration An mean of more than 40,000 organisms were residing on every square metre of the munitions, scientists documented in their research on the observation. The surrounding area was much sparser, with only 8,000 creatures on every meter squared. It is surprising that objects that are intended to destroy everything are hosting so much marine organisms, explains Vedenin. You can see how the natural world adjusts after a major disaster such as the World War II and how, in some way, life finds its way to the most dangerous places. Artificial Features as Marine Environments Artificial features such as shipwrecks, offshore windfarms, drilling platforms and undersea pipes can offer substitutes, restoring some of the destroyed habitat. This investigation demonstrates that explosives could be similarly positive – the explosion of life on those in the Lübeck Bay is expected to be duplicated elsewhere. Between 1946 and the post-war period, 1.6m tons of arms were discarded off the German shoreline. Countless of workers placed them in boats; some were dropped in designated locations, others just thrown overboard during transport. This is the initial instance researchers have documented how ocean organisms has reacted. Worldwide Examples of Ocean Adaptation In the US, retired drilling platforms have transformed into marine habitats Shipwrecks from the World War I have become habitats for creatures along the Potomac in Maryland Military vehicle parts that have become home to coral off Asan in the Pacific island These areas become even more valuable for wildlife as the seas are increasingly stripped by commercial fishing, bottom trawling and boat mooring. Sunken ships and weapons dump sites effectively act as sanctuaries – they are not official reserves, but virtually any kind of human activity is prohibited, states Vedenin. As a result a lot of organisms that are usually rare or declining, such as the Baltic cod, are thriving. Coming Issues Anywhere armed conflict has occurred in the recent history, nearby oceans are typically containing explosives, explains Vedenin. Millions of tons of volatile compounds rest in our seas. The sites of these explosives are poorly mapped, in part because of international boundaries, classified defense data and the fact that records are buried in old files. They create an explosion and safety hazard, as well as risk from the persistent emission of toxic chemicals. As Germany and different states embark on removing these relics, experts plan to safeguard the marine communities that have established in their vicinity. In the Bay of Lübeck weapons are already being removed. It would be wise to replace these iron structures left from munitions with some more secure, some harmless materials, like maybe concrete structures, says Vedenin. He currently hopes that what transpires in the Bay of Lübeck establishes a example for replacing habitats after explosive extraction in other locations – because even the most destructive weaponry can become scaffolding for ocean ecosystems.
