🔗 Share this article World War II Explosives, Torpedo Heads and Mines: How Ocean Creatures Thrives on Abandoned Armaments In the slightly salty sea off the German coast rests a wasteland of Nazi bombs, torpedoes and naval mines. Thrown off boats at the conclusion of the second world war and forgotten about, countless explosives have accumulated over the years. They create a decaying layer on the shallow, muddy seafloor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the explosive stockpile was ignored and neglected. A increasing amount of visitors traveled to the sandy beaches and tranquil sea for jetskiing, kiteboarding and amusement parks. Underwater, the munitions deteriorated. Researchers expected to see a desert, with no organisms because it was all contaminated, explains Andrey Vedenin. When the first scientists went searching to see what they were affecting to the marine environment, the team anticipated finding a desert, with no life because it was all toxic, explains the lead researcher. What they found amazed them. Vedenin recalls his colleagues reacting with shock when the ROV first transmitted footage. That moment was a memorable occasion, he says. Thousands of ocean life had made their homes on the munitions, developing a renewed habitat denser than the seabed nearby. This underwater metropolis was testament to the persistence of marine life. Indeed surprising how much life we observe in places that are considered hazardous and dangerous, he explains. In excess of 40 sea stars had gathered on to one visible fragment of TNT. They were residing on metal shells, detonator compartments and transport cases just a short distance from its volatile core. Fish, crustaceans, anemones and bivalves were all discovered on the old munitions. It resembles a marine reef in terms of the quantity of fauna that was inhabiting the area, states Vedenin. Unexpected Population Density An mean of more than forty thousand animals were residing on every meter squared of the weapons, researchers wrote in their research on the discovery. The adjacent region was much less diverse, with only eight thousand organisms on every meter squared. It is paradoxical that things that are meant to destroy everything are attracting so much life, says Vedenin. One can observe how the natural world evolves after a major disaster such as the second world war and how, in certain respects, life returns to the most dangerous places. Man-made Features as Marine Environments Artificial structures such as shipwrecks, wind turbines, oil rigs and pipelines can provide substitutes, restoring some of the destroyed marine environment. This investigation demonstrates that explosives could be equally beneficial – the bloom of life on those in the Bay of Lübeck is likely to be repeated in different areas. Between 1946 and the post-war period, 1.6 million tonnes of weapons were dumped off the Germany's shoreline. Countless of individuals transported them in boats; some were deposited in specific sites, others just discarded at sea during transport. This is the first time scientists have recorded how ocean organisms has responded. Global Examples of Marine Adaptation In the US, decommissioned drilling platforms have turned into reef ecosystems Shipwrecks from the World War I have become homes for creatures along the Potomac in Maryland Military vehicle parts that have become environment to coral off Asan in Guam These places become even more valuable for wildlife as the marine environments are increasingly stripped by fishing, bottom trawling and boat mooring. Shipwrecks and explosive disposal locations essentially act as refuges – they are not official reserves, but virtually any kind of anthropogenic disturbance is banned, explains Vedenin. Therefore a lot of marine species that are otherwise uncommon or decreasing, such as the cod fish, are flourishing. Coming Considerations Wherever military conflict has occurred in the recent history, adjacent waters are usually containing munitions, explains Vedenin. Millions of tonnes of volatile compounds rest in our seas. The locations of these explosives are insufficiently recorded, partly because of sovereign limits, secret defense data and the fact that records are buried in historical records. They pose an detonation and security hazard, as well as danger from the ongoing release of poisonous compounds. As the German government and additional nations embark on clearing these remains, researchers hope to preserve the habitats that have developed in their vicinity. In the Bay of Lübeck weapons are already being cleared. We should replace these steel remains originating from weapons with certain safer, various safe structures, like perhaps concrete structures, suggests Vedenin. He currently aspires that what happens in Lübeck creates a example for replacing habitats after weapon clearance in other locations – because including the most harmful armaments can become scaffolding for marine organisms.
