🔗 Share this article World War II Bombs, Torpedo Heads and Mines: The Way Marine Life Prosper on Abandoned Armaments In the brackish sea off the Germany's coast sits a graveyard of World War II explosives, torpedoes and mines. Dumped from barges at the end of the second world war and neglected, countless weapons have accumulated over the decades. They create a corroding carpet on the shallow, silty ocean floor of the Bay of Lübeck in the western tip of the Baltic Sea. Over the years, the Nazi arsenal was ignored and forgotten about. A increasing amount of tourists came to the sandy beaches and tranquil sea for water sports, kiteboarding and entertainment venues. Below the waves, the munitions deteriorated. Researchers thought to see a lifeless zone, with no organisms because it was all toxic, states the lead researcher. When the initial researchers went searching to see what they were doing to the marine environment, researchers expected to see a lifeless zone, with nothing living there because it was all poisoned, states the lead researcher. What they observed astonished them. Vedenin recalls his colleagues reacting with shock when the underwater vehicle first transmitted footage. It was a remarkable experience, he recalls. Thousands of marine animals had made their homes on the explosives, creating a renewed habitat richer than the seabed around it. This marine city was proof to the persistence of marine life. It is actually remarkable how much life we discover in areas that are considered toxic and risky, he explains. In excess of 40 sea stars had gathered on to one exposed fragment of TNT. They were residing on metal shells, detonator compartments and carrying containers just centimetres from its volatile core. Marine fish, crustaceans, anemones and bivalves were all discovered on the historic weapons. You could compare it with a marine reef in terms of the amount of fauna that was there, states Vedenin. Unexpected Population Density An average of more than 40,000 organisms were residing on every meter squared of the explosives, experts documented in their study on the finding. The nearby seabed was much less diverse, with only 8,000 organisms on every meter squared. It is paradoxical that objects that are intended to kill all life are drawing so much life, states Vedenin. One can observe how nature adjusts after a major disaster such as the World War II and how, in certain respects, marine life establishes itself to the most hazardous areas. Man-made Features as Ocean Habitats Artificial structures such as shipwrecks, offshore windfarms, oil rigs and undersea pipes can create substitutes, replacing some of the lost marine environment. This investigation shows that munitions could be equally positive – the bloom of marine organisms on those in the Bay of Lübeck is likely to be duplicated in other locations. Between 1946 and 1948, 1.6m tonnes of weapons were disposed of off the Germany's shoreline. Numerous of workers transported them in vessels; some were deposited in allocated locations, others just thrown overboard en route. This is the initial instance researchers have documented how marine life has responded. Worldwide Instances of Marine Adaptation In the US, retired drilling platforms have become reef ecosystems Sunken ships from the first world war have become homes for marine life along the Potomac River in the state of Maryland Tank tracks that have become habitat to reef-building organisms off Asan in the Pacific island These places become even more valuable for marine life as the seas are increasingly stripped by fishing, bottom trawling and boat mooring. Shipwrecks and explosive disposal locations essentially function as sanctuaries – they are not national parks, but nearly any kind of anthropogenic disturbance is restricted, states Vedenin. Consequently a lot of marine species that are typically scarce or diminishing, such as the cod fish, are thriving. Coming Considerations Anywhere armed conflict has taken place in the past 100 years, nearby oceans are typically strewn with weapons, says Vedenin. Many millions of tons of volatile compounds remain in our marine environments. The sites of these explosives are poorly mapped, partially because of national borders, secret military information and the situation that archives are stored in old files. They pose an explosion and security danger, as well as threat from the continuous leakage of poisonous compounds. As Germany and additional nations embark on extracting these artifacts, scientists plan to protect the ecosystems that have established nearby. In the Lübeck Bay explosives are already being removed. We should substitute these iron structures left from munitions with some less dangerous, some safe structures, like maybe man-made habitats, suggests Vedenin. He now aspires that what occurs in Lübeck establishes a precedent for substituting habitats after munitions removal elsewhere – because even the most harmful weaponry can become foundation for marine organisms.
