🔗 Share this article Nazi Explosives, Torpedoes and Mines: How Ocean Creatures Thrives on Dumped Weapons In the slightly salty waters off the Germany's coast rests a wasteland of World War II explosives, torpedoes and mines. Discarded from barges at the end of the World War II and left behind, numerous munitions have fused into clusters over the decades. They comprise a corroding carpet on the shallow, muddy seafloor of the Lübeck Bay in the western part of the Baltic Sea. Over the decades, the wartime weapons was overlooked and neglected. A growing number of visitors traveled to the sandy beaches and calm waters for water sports, kiteboarding and amusement parks. Below the waves, the munitions deteriorated. Researchers thought to see a lifeless zone, with nothing living there because it was all contaminated, states the lead researcher. When the first scientists went searching to see what they were doing to the ecosystem, some of us anticipated finding a lifeless zone, with no life because it was all poisoned, explains Andrey Vedenin. What they discovered surprised them. Vedenin remembers his scientists shouting with surprise when the underwater vehicle first relayed pictures. That moment was a remarkable experience, he notes. Countless of marine animals had established habitats on the explosives, developing a renewed marine community more populous than the sea floor nearby. This marine city was testament to the resilience of marine life. Truly remarkable how much marine organisms we discover in locations that are expected to be dangerous and dangerous, he states. Over 40 sea stars had clustered on to one exposed chunk of explosive material. They were dwelling on steel casings, ignition chambers and carrying containers just centimetres from its explosive filling. Fish, crustaceans, anemones and mussels were all discovered on the historic weapons. It's similar to a marine reef in terms of the amount of fauna that was inhabiting the area, notes Vedenin. Remarkable Population Density An average of more than 40,000 animals were living on every meter squared of the munitions, experts wrote in their research on the observation. The surrounding area was much poorer in life, with only 8,000 organisms on every square metre. It is ironic that things that are intended to eliminate all life are hosting so much life, explains Vedenin. You can see how the natural world adjusts after a catastrophic event such as the second world war and how, in some way, life finds its way to the most risky locations. Artificial Features as Marine Habitats Man-made features such as sunken vessels, wind turbines, oil rigs and pipelines can create substitutes, compensating for some of the lost habitat. This investigation reveals that weapons could be equally positive – the explosion of marine organisms on those in the Lübeck Bay is likely to be repeated in other locations. Between the late 1940s and 1948, 1.6m tons of arms were discarded off the Germany's coast. Numerous of individuals transported them in vessels; some were placed in designated areas, others just discarded at sea during transport. This is the initial instance scientists have documented how marine life has responded. Global Examples of Ocean Adaptation In the US, decommissioned drilling platforms have transformed into reef ecosystems Shipwrecks from the first world war have become homes for marine life along the Potomac in Maryland Military vehicle parts that have become habitat to coral off Asan in the Pacific island These places become even more important for marine life as the seas are increasingly depleted by fishing, seafloor dredging and boat mooring. Shipwrecks and weapons dump sites effectively act as refuges – they are not official reserves, but virtually any kind of human activity is banned, says Vedenin. Consequently a many of organisms that are typically scarce or declining, such as the cod fish, are prospering. Future Issues Wherever military conflict has taken place in the past 100 years, adjacent waters are typically littered with explosives, states Vedenin. Many millions of tonnes of dangerous substances rest in our seas. The locations of these weapons are poorly documented, in part because of sovereign limits, classified armed forces records and the situation that documents are buried in historic archives. They pose an explosion and security danger, as well as threat from the ongoing release of hazardous substances. As Germany and additional nations start removing these artifacts, scientists plan to safeguard the habitats that have formed around them. In the Bay of Lübeck munitions are already being cleared. We should substitute these steel remains originating from munitions with some less dangerous, various non-dangerous structures, like maybe artificial reefs, states Vedenin. He now aspires that what happens in the Bay of Lübeck creates a example for replacing structures after munitions removal in different areas – because even the most destructive armaments can become foundation for ocean ecosystems.
