🔗 Share this article Nazi Munitions, Torpedo Heads and Mines: The Way Ocean Creatures Thrives on Discarded Armaments In the brackish waters off the Germany's shoreline rests a collection of World War II explosives, torpedo heads and naval mines. Discarded from vessels at the conclusion of the second world war and left behind, numerous weapons have accumulated over the decades. They comprise a rusting carpet on the shallow, silty seafloor of the Bay of Lübeck in the western part of the Baltic. Over the decades, the explosive stockpile was overlooked and forgotten about. A increasing amount of visitors flocked to the coastal areas and calm waters for water sports, kiteboarding and amusement parks. Beneath the surface, the weapons deteriorated. Some of us thought to see a desert, with no organisms because it was all contaminated, says Andrey Vedenin. When the team went investigating to see what they were affecting to the marine environment, the team thought they would find a desert, with nothing living there because it was all poisoned, states a scientist. What they observed surprised them. Vedenin recalls his colleagues shouting with surprise when the ROV first sent the images back. That moment was a great moment, he says. Countless of sea creatures had established habitats among the explosives, forming a regenerated habitat denser than the sea floor around it. This marine city was proof to the persistence of marine life. Truly astonishing how much marine organisms we find in areas that are expected to be toxic and harmful, he states. More than 40 sea stars had piled on to one visible piece of explosive material. They were living on iron containers, ignition chambers and storage boxes just a short distance from its dangerous content. Fish, crabs, sea anemones and mussels were all discovered on the discarded explosives. You could compare it with a coral reef in terms of the amount of fauna that was there, says Vedenin. Unexpected Creature Concentration An average of more than 40,000 creatures were living on every meter squared of the explosives, researchers documented in their research on the observation. The surrounding area was much poorer in life, with only eight thousand creatures on every meter squared. It is ironic that items that are meant to destroy all life are attracting so much marine organisms, explains Vedenin. One can observe how the natural world evolves after a devastating occurrence such as the World War II and how, in certain respects, life establishes itself to the most dangerous places. Artificial Structures as Marine Environments Artificial structures such as shipwrecks, wind turbines, oil rigs and undersea pipes can offer replacements, compensating for some of the lost habitat. This investigation shows that weapons could be comparably advantageous – the proliferation of marine organisms on those in the Lübeck Bay is probable to be repeated elsewhere. Between the late 1940s and the post-war period, 1.6m tonnes of arms were disposed of off the German shoreline. Numerous of individuals transported them in boats; a portion were placed in specific locations, the remainder just thrown overboard during transport. This is the initial instance experts have studied how ocean organisms has adapted. Worldwide Instances of Marine Transformation In the US, retired oil and gas structures have transformed into reef ecosystems Shipwrecks from the World War I have become habitats for wildlife along the Potomac River in the state of Maryland Military vehicle parts that have become home to reef-building organisms off Asan in Guam These locations become even more important for marine life as the seas are increasingly stripped by fishing, seafloor dredging and boat mooring. Shipwrecks and weapons dump sites effectively serve as refuges – they are not official reserves, but virtually any kind of anthropogenic disturbance is restricted, states Vedenin. As a result a lot of organisms that are otherwise rare or diminishing, such as the cod fish, are flourishing. Coming Considerations Anywhere armed conflict has occurred in the recent history, surrounding seas are typically strewn with explosives, states Vedenin. Many millions of tons of explosive material remain in our seas. The locations of these munitions are poorly documented, partly because of national borders, secret armed forces records and the situation that documents are buried in old files. They pose an detonation and safety hazard, as well as risk from the ongoing release of toxic chemicals. As Germany and other countries start extracting these remains, scientists hope to protect the marine communities that have formed in their vicinity. In the Lübeck Bay munitions are currently being extracted. It would be wise to substitute these steel remains originating from weapons with certain more secure, various safe materials, like possibly man-made habitats, says Vedenin. He currently hopes that what happens in the Bay of Lübeck sets a precedent for substituting habitats after explosive extraction elsewhere – because even the most harmful weaponry can become framework for marine organisms.
