🔗 Share this article World War II Bombs, Torpedoes and Mines: The Way Marine Life Thrives on Abandoned Weapons In the slightly salty waters off the Germany's shoreline rests a graveyard of Nazi bombs, torpedo heads and mines. Discarded from barges at the conclusion of the World War II and neglected, thousands explosives have become matted together over the decades. They form a decaying carpet on the low-depth, silty ocean floor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the explosive stockpile was overlooked and forgotten about. A growing number of tourists came to the sandy beaches and tranquil sea for water sports, kiteboarding and amusement parks. Below the waves, the munitions deteriorated. Some of us expected to see a barren area, with no organisms because it was all poisoned, explains a scientist. When the team went looking to see what they were affecting to the ecosystem, the team thought they would find a desert, with no organisms because it was all toxic, states Andrey Vedenin. What they found surprised them. Vedenin recalls his colleagues reacting with shock when the submersible first sent the images back. It was a memorable occasion, he notes. Countless of ocean life had established habitats amid the weapons, creating a revitalized marine community more populous than the sea floor nearby. This underwater metropolis was evidence to the persistence of marine life. Truly remarkable how much marine organisms we observe in locations that are expected to be toxic and harmful, he says. Over 40 starfish had gathered on to one exposed chunk of explosive material. They were living on metal shells, ignition chambers and carrying containers just a short distance from its volatile core. Fish, crabs, anemones and bivalves were all found on the historic weapons. It resembles a coral reef in terms of the quantity of fauna that was present, notes Vedenin. Unexpected Population Density An average of more than forty thousand organisms were living on every meter squared of the weapons, researchers reported in their paper on the finding. The surrounding area was much sparser, with only 8,000 creatures on every meter squared. It is surprising that things that are meant to kill all life are hosting so much marine organisms, states Vedenin. It's evident how nature adjusts after a devastating occurrence such as the World War II and how, in certain respects, marine life returns to the most risky areas. Artificial Features as Marine Habitats Man-made constructions such as shipwrecks, wind turbines, drilling platforms and undersea pipes can create alternatives, replacing some of the removed habitat. This study demonstrates that explosives could be equally positive – the explosion of life on those in the Bay of Lübeck is probable to be duplicated elsewhere. Between the late 1940s and the post-war period, 1.6m tons of arms were discarded off the Germany's shoreline. Thousands of individuals loaded them in barges; some were deposited in specific locations, the remainder just thrown overboard during transport. This is the first time experts have recorded how ocean organisms has responded. Worldwide Examples of Marine Transformation In the US, retired drilling platforms have transformed into coral reefs Shipwrecks from the first world war have become habitats for marine life along the Potomac River in the state of Maryland Tank tracks that have become home to coral off Asan beach in Guam These places become even more crucial for marine life as the seas are increasingly stripped by fishing, seafloor dredging and anchoring. Shipwrecks and weapons dump sites essentially serve as sanctuaries – they are not national parks, but almost any kind of anthropogenic disturbance is restricted, states Vedenin. As a result a lot of species that are otherwise scarce or diminishing, such as the Baltic cod, are flourishing. Coming Factors Wherever warfare has occurred in the recent history, adjacent waters are typically strewn with weapons, explains Vedenin. Many millions of tonnes of dangerous substances lie in our seas. The positions of these munitions are inadequately mapped, in part because of international boundaries, classified military information and the reality that records are stored in historical records. They pose an detonation and safety risk, as well as risk from the continuous emission of poisonous compounds. As the German government and different states embark on extracting these remains, researchers hope to preserve the marine communities that have developed around them. In the Bay of Lübeck weapons are currently being removed. Researchers recommend replace these metal carcasses originating from weapons with some less dangerous, some non-dangerous structures, like maybe concrete structures, states Vedenin. He currently wishes that what happens in the Bay of Lübeck establishes a example for replacing material after weapon clearance elsewhere – because even the most destructive weaponry can become framework for ocean ecosystems.
