🔗 Share this article Nazi Munitions, Torpedo Heads and Mines: The Way Ocean Creatures Flourishes on Abandoned Weapons In the brackish sea off the German coast lies a collection of World War II explosives, torpedo heads and mines. Dumped from boats at the end of the World War II and left behind, countless explosives have fused into clusters over the decades. They comprise a rusting blanket on the low-depth, silty seafloor of the Bay of Lübeck in the western part of the Baltic. Over the years, the Nazi arsenal was overlooked and neglected. A growing number of visitors traveled to the coastal areas and tranquil sea for water sports, kiteboarding and amusement parks. Below the waves, the munitions deteriorated. Researchers thought to see a desert, with no life because it was all toxic, says the lead researcher. When the first scientists went investigating to see what they were doing to the marine environment, the team expected to see a lifeless zone, with no life because it was all contaminated, says a scientist. What they observed astonished them. Vedenin recounts his scientists shouting with surprise when the submersible first transmitted footage. It was a memorable occasion, he says. Numerous of marine animals had made their homes among the weapons, forming a revitalized marine community denser than the seabed nearby. This underwater metropolis was evidence to the resilience of life. It is actually astonishing how much marine organisms we discover in locations that are supposed to be toxic and dangerous, he says. Over 40 starfish had clustered on to one accessible fragment of explosive material. They were dwelling on steel casings, detonator compartments and carrying containers just a short distance from its explosive filling. Fish, crabs, sea anemones and mussels were all found on the historic weapons. You could compare it with a coral reef in terms of the quantity of animal life that was there, states Vedenin. Remarkable Population Density An mean of more than forty thousand animals were dwelling on every meter squared of the munitions, experts documented in their study on the finding. The adjacent region was much poorer in life, with only 8,000 individuals on every square metre. It is paradoxical that items that are meant to destroy everything are attracting so much life, says Vedenin. One can observe how the natural world adapts after a devastating occurrence such as the World War II and how, in certain respects, life establishes itself to the most dangerous places. Artificial Features as Marine Habitats Artificial features such as shipwrecks, wind turbines, oil rigs and pipelines can provide alternatives, replacing some of the destroyed habitat. This study demonstrates that munitions could be equally beneficial – the proliferation of life on those in the Lübeck Bay is likely to be found elsewhere. Between 1946 and 1948, 1.6 million tons of munitions were disposed of off the German shoreline. Thousands of workers loaded them in barges; some were deposited in specific locations, the remainder just discarded at sea while traveling. This is the initial instance scientists have studied how ocean organisms has adapted. Worldwide Examples of Marine Adaptation In the US, decommissioned oil and gas structures have become reef ecosystems Sunken ships from the first world war have become homes for wildlife along the Potomac River in the state of Maryland Military vehicle parts that have become habitat to coral off Asan in Guam These locations become even more crucial for marine life as the marine environments are increasingly depleted by fishing, bottom trawling and anchoring. Sunken ships and weapons dump sites practically function as refuges – they are not official reserves, but nearly any kind of human activity is prohibited, explains Vedenin. Consequently a numerous of species that are typically uncommon or decreasing, such as the Baltic cod, are prospering. Future Issues Wherever military conflict has happened in the past 100 years, surrounding seas are typically littered with explosives, says Vedenin. Millions of tons of dangerous substances lie in our oceans. The sites of these explosives are poorly documented, in part because of sovereign limits, secret defense data and the reality that documents are hidden in old files. They present an detonation and safety hazard, as well as risk from the persistent leakage of toxic chemicals. As Germany and additional nations begin extracting these relics, experts aim to preserve the ecosystems that have formed nearby. In the Bay of Lübeck explosives are presently being extracted. It would be wise to substitute these iron structures left from weapons with some less dangerous, various safe objects, like possibly artificial reefs, suggests Vedenin. He presently hopes that what transpires in the Bay of Lübeck establishes a model for replacing habitats after explosive extraction in different areas – because also the most destructive explosives can become framework for marine organisms.
