🔗 Share this article World War II Munitions, Torpedo Heads and Naval Mines: The Way Marine Life Prosper on Dumped Weapons In the brackish sea off the Germany's coast rests a wasteland of World War II explosives, torpedoes and mines. Discarded from barges at the conclusion of the second world war and neglected, thousands explosives have accumulated over the years. They form a decaying blanket on the low-depth, muddy ocean floor of the Bay of Lübeck in the western tip of the Baltic Sea. Over the years, the wartime weapons was ignored and forgotten about. A growing number of visitors traveled to the coastal areas and calm waters for jetskiing, kiteboarding and amusement parks. Beneath the surface, the munitions eroded. Researchers thought to see a lifeless zone, with nothing living there because it was all poisoned, states a scientist. When the first scientists went looking to see what they were doing to the ecosystem, researchers anticipated finding a desert, with nothing living there because it was all toxic, explains a scientist. What they observed amazed them. Vedenin recalls his scientists shouting with surprise when the submersible first transmitted footage. It was a remarkable experience, he recalls. Countless of ocean life had made their homes amid the munitions, developing a regenerated marine community denser than the sea floor surrounding it. This marine city was testament to the persistence of life. Truly remarkable how much marine organisms we find in areas that are expected to be hazardous and harmful, he states. Over 40 sea stars had piled on to one accessible piece of explosive material. They were living on metal shells, ignition chambers and storage boxes just centimetres from its explosive filling. Marine fish, crabs, sea anemones and mussels were all found on the old munitions. It's similar to a reef ecosystem in terms of the abundance of animal life that was inhabiting the area, states Vedenin. Unexpected Population Density An mean of more than 40,000 animals were dwelling on every meter squared of the munitions, researchers reported in their research on the finding. The surrounding area was much sparser, with only 8,000 organisms on every meter squared. It is surprising that objects that are designed to kill everything are attracting so much marine organisms, says Vedenin. It's evident how the natural world adapts after a major disaster such as the World War II and how, in some way, life establishes itself to the most dangerous areas. Man-made Features as Marine Environments Man-made features such as sunken vessels, offshore windfarms, oil rigs and pipelines can provide replacements, restoring some of the destroyed habitat. This investigation reveals that munitions could be equally beneficial – the proliferation of marine organisms on those in the Lübeck Bay is expected to be duplicated elsewhere. Between the late 1940s and 1948, 1.6m tons of munitions were dumped off the Germany's shoreline. Countless of individuals transported them in boats; a portion were dropped in designated locations, the remainder just dumped while traveling. This is the first time researchers have recorded how marine life has adapted. Worldwide Instances of Marine Transformation In the US, retired drilling platforms have turned into marine habitats Submerged vessels from the World War I have become environments for wildlife along the Potomac River in the state of Maryland Military vehicle parts that have become environment to reef-building organisms off Asan beach in the Pacific island These areas become even more valuable for marine life as the marine environments are increasingly denuded by commercial fishing, seafloor dredging and anchoring. Shipwrecks and explosive disposal locations effectively serve as refuges – they are not national parks, but nearly any kind of human activity is prohibited, explains Vedenin. As a result a many of organisms that are typically uncommon or diminishing, such as the cod fish, are thriving. Coming Factors Anywhere military conflict has happened in the last century, adjacent waters are typically littered with munitions, says Vedenin. Many millions of tonnes of explosive material lie in our seas. The positions of these weapons are inadequately mapped, in part because of national borders, restricted defense data and the reality that records are hidden in historical records. They pose an detonation and safety risk, as well as danger from the ongoing leakage of poisonous compounds. As the German government and different states start extracting these remains, experts hope to protect the marine communities that have established nearby. In the Bay of Lübeck explosives are currently being extracted. It would be wise to substitute these iron structures originating from weapons with some less dangerous, some harmless objects, like possibly man-made habitats, suggests Vedenin. He now aspires that what transpires in Lübeck establishes a precedent for replacing habitats after explosive extraction in other locations – because including the most harmful explosives can become foundation for ocean ecosystems.
