🔗 Share this article Nazi Bombs, Torpedoes and Mines: How Marine Life Thrives on Discarded Weapons In the slightly salty sea off the German shoreline lies a collection of World War II explosives, torpedoes and mines. Discarded from barges at the end of the World War II and neglected, thousands munitions have accumulated over the decades. They create a rusting carpet on the low-depth, silty seafloor of the Bay of Lübeck in the western tip of the Baltic. Over the decades, the explosive stockpile was overlooked and forgotten about. A increasing amount of tourists traveled to the coastal areas and tranquil sea for jetskiing, kiteboarding and entertainment venues. Beneath the surface, the weapons eroded. Some of us expected to see a lifeless zone, with no organisms because it was all contaminated, states the lead researcher. When the team went looking to see what they were doing to the ecosystem, researchers anticipated finding a barren area, with no organisms because it was all contaminated, says a scientist. What they discovered astonished them. Vedenin remembers his team members shouting with surprise when the submersible first sent the images back. This was a remarkable experience, he says. Thousands of marine animals had settled on the weapons, creating a revitalized habitat richer than the seabed nearby. This ocean community was evidence to the tenacity of life. Indeed remarkable how much marine organisms we find in areas that are expected to be hazardous and harmful, he says. In excess of 40 sea stars had gathered on to one accessible piece of explosive material. They were residing on iron containers, fuse pockets and carrying containers just centimetres from its explosive filling. Marine fish, crabs, sea anemones and bivalves were all discovered on the old munitions. It's similar to a reef ecosystem in terms of the quantity of creatures that was present, says Vedenin. Surprising Creature Concentration An average of more than forty thousand creatures were dwelling on every meter squared of the munitions, researchers reported in their paper on the discovery. The adjacent region was much less diverse, with only eight thousand organisms on every meter squared. It is surprising that objects that are designed to destroy all life are attracting so much marine organisms, explains Vedenin. It's evident how nature adapts after a devastating occurrence such as the World War II and how, in some way, life finds its way to the most risky areas. Man-made Features as Ocean Habitats Man-made structures such as shipwrecks, wind turbines, oil rigs and pipelines can provide replacements, compensating for some of the destroyed habitat. This study shows that weapons could be equally beneficial – the proliferation of life on those in the Lübeck Bay is probable to be found in different areas. Between 1946 and 1948, 1.6m tons of munitions were dumped off the German coast. Thousands of workers placed them in boats; a portion were deposited in allocated sites, the remainder just dumped while traveling. This is the initial instance experts have studied how marine life has responded. Worldwide Instances of Marine Transformation In the United States, retired oil and gas structures have become coral reefs Shipwrecks from the World War I have become habitats for wildlife along the Potomac in the state of Maryland Tank tracks that have become environment to coral off Asan beach in Guam These places become even more important for wildlife as the marine environments are increasingly stripped by commercial fishing, bottom trawling and boat mooring. Shipwrecks and weapons dump sites practically act as protected areas – they are not national parks, but nearly any kind of human activity is restricted, states Vedenin. Therefore a many of marine species that are typically uncommon or decreasing, such as the Baltic cod, are thriving. Coming Issues Wherever military conflict has taken place in the recent history, adjacent waters are typically littered with munitions, states Vedenin. Many millions of tons of volatile compounds remain in our seas. The sites of these explosives are poorly documented, partly because of sovereign limits, restricted military information and the reality that archives are buried in old files. They pose an detonation and security danger, as well as risk from the continuous emission of toxic chemicals. As the German government and additional nations embark on extracting these remains, experts aim to protect the marine communities that have developed in their vicinity. In the Bay of Lübeck explosives are presently being cleared. Researchers recommend substitute these iron structures originating from weapons with some safer, various safe structures, like possibly man-made habitats, says Vedenin. He presently wishes that what transpires in the Bay of Lübeck establishes a precedent for substituting habitats after munitions removal in different areas – because even the most damaging explosives can become foundation for marine organisms.
