🔗 Share this article Nazi Explosives, Torpedo Heads and Mines: The Way Ocean Creatures Thrives on Abandoned Weapons In the brackish waters off the German coast sits a collection of World War II explosives, torpedoes and naval mines. Dumped from vessels at the end of the second world war and forgotten about, numerous weapons have accumulated over the years. They form a decaying blanket on the shallow, silty ocean floor of the Bay of Lübeck in the western tip of the Baltic. Over the decades, the Nazi arsenal was overlooked and forgotten about. A increasing amount of tourists flocked to the coastal areas and calm waters for jetskiing, kite surfing and entertainment venues. Below the waves, the weapons decayed. Researchers thought to see a lifeless zone, with nothing living there because it was all poisoned, states Andrey Vedenin. When the team went looking to see what they were doing to the ecosystem, researchers thought they would find a desert, with no life because it was all contaminated, explains a scientist. What they observed amazed them. Vedenin recounts his scientists reacting with shock when the ROV first sent the images back. That moment was a great moment, he says. Thousands of marine animals had settled on the weapons, developing a revitalized ecosystem denser than the ocean bottom around it. This underwater metropolis was testament to the persistence of life. Truly surprising how much life we find in places that are expected to be toxic and harmful, he states. Over 40 sea stars had clustered on to one visible fragment of TNT. They were residing on metal shells, fuse pockets and transport cases just a short distance from its volatile core. Fish, crabs, anemones and mussels were all observed on the old munitions. It resembles a marine reef in terms of the amount of creatures that was there, says Vedenin. Remarkable Creature Concentration An average of more than 40,000 animals were living on every meter squared of the weapons, scientists reported in their research on the discovery. The adjacent region was much less diverse, with only 8,000 organisms on every meter squared. It is surprising that objects that are meant to destroy all life are attracting so much life, explains Vedenin. It's evident how nature adjusts after a catastrophic event such as the World War II and how, in some way, marine life finds its way to the most risky locations. Man-made Features as Marine Habitats Man-made structures such as sunken vessels, offshore windfarms, drilling platforms and pipelines can create replacements, restoring some of the lost habitat. This research shows that weapons could be similarly beneficial – the explosion of life on those in the Lübeck Bay is likely to be repeated elsewhere. Between the late 1940s and 1948, 1.6 million tonnes of arms were dumped off the German shoreline. Countless of people transported them in boats; a portion were deposited in specific locations, the remainder just thrown overboard during transport. This is the initial instance researchers have studied how ocean organisms has responded. Global Examples of Ocean Transformation In the United States, decommissioned energy installations have turned into reef ecosystems Shipwrecks from the first world war have become habitats for marine life along the Potomac River in Maryland Tank tracks that have become home to reef-building organisms off Asan beach in the Pacific island These areas become even more important for marine life as the seas are increasingly stripped by fishing, seafloor dredging and boat mooring. Shipwrecks and explosive disposal locations effectively serve as protected areas – they are not national parks, but almost any kind of anthropogenic disturbance is prohibited, states Vedenin. Therefore a lot of species that are otherwise uncommon or declining, such as the Baltic cod, are flourishing. Future Considerations Anywhere military conflict has happened in the past 100 years, adjacent waters are usually containing munitions, states Vedenin. Millions of tons of explosive material lie in our marine environments. The positions of these explosives are inadequately documented, partially because of sovereign limits, secret armed forces records and the situation that documents are stored in historic archives. They present an explosion and security danger, as well as risk from the persistent leakage of poisonous compounds. As the German government and different states begin extracting these remains, experts aim to safeguard the ecosystems that have developed nearby. In the Lübeck Bay weapons are presently being cleared. It would be wise to substitute these steel remains originating from munitions with certain less dangerous, various safe materials, like maybe artificial reefs, suggests Vedenin. He now hopes that what transpires in the Bay of Lübeck sets a example for replacing structures after explosive extraction in different areas – because even the most harmful weaponry can become framework for ocean ecosystems.
