🔗 Share this article Nazi Explosives, Torpedo Heads and Naval Mines: The Way Marine Life Thrives on Discarded Armaments In the brackish sea off the Germany's shoreline lies a wasteland of World War II explosives, torpedoes and mines. Dumped from barges at the end of the World War II and left behind, thousands munitions have fused into clusters over the decades. They form a corroding blanket on the shallow, muddy seafloor of the Lübeck Bay in the western tip of the Baltic. Over the decades, the wartime weapons was ignored and neglected. A growing number of visitors traveled to the coastal areas and calm waters for water sports, kite surfing and amusement parks. Underwater, the munitions decayed. Researchers thought to see a lifeless zone, with no life because it was all toxic, states Andrey Vedenin. When the first scientists went searching to see what they were doing to the ecosystem, the team thought they would find a desert, with no life because it was all toxic, explains the lead researcher. What they found surprised them. Vedenin recounts his colleagues shouting with surprise when the underwater vehicle first transmitted footage. That moment was a remarkable experience, he recalls. Thousands of ocean life had established habitats among the weapons, creating a renewed habitat more populous than the seabed around it. This underwater metropolis was proof to the resilience of marine life. Truly surprising how much life we discover in places that are considered dangerous and risky, he says. More than 40 sea stars had clustered on to one accessible piece of explosive material. They were living on steel casings, fuse pockets and carrying containers just a short distance from its dangerous content. Fish, crustaceans, anemones and bivalves were all discovered on the discarded explosives. You could compare it with a coral reef in terms of the abundance of fauna that was present, notes Vedenin. Unexpected Population Density An mean of more than 40,000 organisms were residing on every meter squared of the explosives, experts reported in their paper on the observation. The nearby seabed was much sparser, with only eight thousand individuals on every square metre. It is surprising that items that are meant to kill everything are hosting so much life, says Vedenin. You can see how the natural world adapts after a major disaster such as the second world war and how, in some way, marine life returns to the most dangerous places. Artificial Structures as Marine Habitats Man-made features such as sunken vessels, wind turbines, oil rigs and undersea pipes can provide substitutes, compensating for some of the lost habitat. This research demonstrates that weapons could be comparably positive – the proliferation of life on those in the Lübeck Bay is probable to be repeated in different areas. Between the late 1940s and 1948, 1.6 million tons of munitions were disposed of off the Germany's shoreline. Numerous of workers loaded them in boats; a portion were deposited in specific areas, the remainder just thrown overboard during transport. This is the first time researchers have studied how marine life has adapted. Global Instances of Ocean Adaptation In the US, retired oil and gas structures have transformed into reef ecosystems Shipwrecks from the first world war have become environments for marine life along the Potomac River in Maryland Military vehicle parts that have become home to reef-building organisms off Asan in the Pacific island These locations become even more valuable for wildlife as the marine environments are increasingly depleted by commercial fishing, seafloor dredging and boat mooring. Shipwrecks and weapons dump sites practically function as refuges – they are not official reserves, but virtually any kind of human activity is prohibited, says Vedenin. As a result a many of marine species that are usually uncommon or declining, such as the cod fish, are flourishing. Future Issues Anywhere armed conflict has happened in the recent history, adjacent waters are often strewn with weapons, states Vedenin. Many millions of tonnes of volatile compounds rest in our oceans. The locations of these weapons are inadequately recorded, in part because of national borders, classified military information and the situation that records are hidden in old files. They pose an explosion and safety risk, as well as danger from the ongoing leakage of toxic chemicals. As Germany and other countries begin removing these artifacts, experts hope to protect the ecosystems that have established nearby. In the Bay of Lübeck explosives are currently being cleared. Researchers recommend replace these metal carcasses originating from munitions with certain less dangerous, various safe objects, like maybe man-made habitats, says Vedenin. He currently wishes that what transpires in the Bay of Lübeck sets a example for replacing structures after weapon clearance in different areas – because including the most damaging weaponry can become framework for marine organisms.
