🔗 Share this article World War II Bombs, Torpedoes and Mines: How Ocean Creatures Flourishes on Discarded Armaments In the slightly salty sea off the Germany's coast lies a wasteland of World War II explosives, torpedoes and naval mines. Thrown off barges at the conclusion of the second world war and left behind, countless munitions have fused into clusters over the decades. They create a decaying carpet on the shallow, silty seafloor of the Bay of Lübeck in the western part of the Baltic Sea. Over the decades, the wartime weapons was overlooked and forgotten about. A increasing amount of tourists flocked to the coastal areas and calm waters for water sports, kiteboarding and amusement parks. Below the waves, the weapons deteriorated. Some of us thought to see a barren area, with no organisms because it was all contaminated, states the lead researcher. When the team went investigating to see what they were affecting to the marine environment, researchers thought they would find a barren area, with no organisms because it was all contaminated, states the lead researcher. What they found surprised them. Vedenin recounts his scientists exclaiming in amazement when the submersible first sent the images back. This was a great moment, he says. Thousands of ocean life had settled amid the weapons, creating a revitalized ecosystem more populous than the ocean bottom nearby. This marine city was proof to the tenacity of marine life. Truly surprising how much marine organisms we discover in locations that are considered toxic and harmful, he says. Over 40 sea stars had piled on to one accessible piece of explosive material. They were dwelling on metal shells, ignition chambers and transport cases just centimetres from its dangerous content. Fish, crabs, anemones and mussels were all observed on the discarded explosives. It's similar to a reef ecosystem in terms of the amount of animal life that was present, says Vedenin. Unexpected Population Density An mean of more than 40,000 creatures were living on every square metre of the explosives, scientists wrote in their research on the finding. The adjacent region was much sparser, with only 8,000 creatures on every square metre. It is surprising that objects that are designed to eliminate all life are attracting so much marine organisms, says Vedenin. It's evident how the natural world adjusts after a major disaster such as the second world war and how, in some way, marine life finds its way to the most risky locations. Artificial Features as Marine Environments Man-made constructions such as sunken vessels, offshore windfarms, drilling platforms and pipelines can offer replacements, replacing some of the removed marine environment. This investigation demonstrates that munitions could be equally advantageous – the explosion of marine organisms on those in the Bay of Lübeck is probable to be repeated in different areas. Between 1946 and the post-war period, 1.6m tonnes of weapons were discarded off the Germany's shoreline. Numerous of workers transported them in barges; some were dropped in designated sites, the remainder just discarded at sea during transport. This is the first time experts have recorded how marine life has responded. Worldwide Instances of Ocean Transformation In the United States, decommissioned drilling platforms have transformed into coral reefs Submerged vessels from the World War I have become habitats for wildlife along the Potomac River in the state of Maryland Military vehicle parts that have become home to reef-building organisms off Asan beach in Guam These areas become even more important for organisms as the seas are increasingly denuded by commercial fishing, seafloor dredging and boat mooring. Shipwrecks and munitions areas essentially act as protected areas – they are not national parks, but almost any kind of anthropogenic disturbance is banned, explains Vedenin. As a result a many of species that are otherwise uncommon or declining, such as the cod fish, are thriving. Coming Considerations Wherever military conflict has taken place in the last century, surrounding seas are typically containing explosives, says Vedenin. Many millions of tonnes of volatile compounds lie in our seas. The locations of these munitions are insufficiently mapped, partly because of international boundaries, restricted military information and the situation that records are buried in historical records. They present an detonation and security risk, as well as danger from the persistent emission of hazardous substances. As Germany and different states begin removing these artifacts, researchers hope to protect the ecosystems that have formed around them. In the Lübeck Bay explosives are already being extracted. We should replace these steel remains originating from weapons with certain less dangerous, some safe structures, like maybe artificial reefs, suggests Vedenin. He currently hopes that what occurs in the Bay of Lübeck establishes a precedent for replacing material after explosive extraction elsewhere – because including the most destructive armaments can become scaffolding for ocean ecosystems.
