🔗 Share this article World War II Munitions, Torpedoes and Naval Mines: The Way Marine Life Flourishes on Dumped Weapons In the brackish waters off the Germany's shoreline lies a graveyard of World War II explosives, torpedoes and mines. Discarded from vessels at the conclusion of the second world war and left behind, countless weapons have become matted together over the years. They comprise a corroding blanket on the shallow, silty seafloor of the Bay of Lübeck in the western tip of the Baltic Sea. Over the decades, the wartime weapons was overlooked and neglected. A increasing amount of tourists traveled to the sandy beaches and calm waters for water sports, kite surfing and amusement parks. Underwater, the weapons decayed. We initially anticipated to see a lifeless zone, with nothing living there because it was all contaminated, states the lead researcher. When the initial researchers went searching to see what they were doing to the ecosystem, some of us anticipated finding a lifeless zone, with no organisms because it was all contaminated, states Andrey Vedenin. What they observed amazed them. Vedenin remembers his team members reacting with shock when the submersible first sent the images back. This was a memorable occasion, he notes. Countless of ocean life had made their homes on the weapons, developing a regenerated marine community denser than the ocean bottom surrounding it. This underwater metropolis was proof to the resilience of marine life. It is actually astonishing how much marine organisms we find in locations that are considered toxic and risky, he states. More than 40 starfish had clustered on to one visible fragment of TNT. They were dwelling on metal shells, ignition chambers and carrying containers just centimetres from its dangerous content. Marine fish, crabs, sea anemones and bivalves were all discovered on the historic weapons. It resembles a marine reef in terms of the abundance of fauna that was present, states Vedenin. Remarkable Population Density An average of more than forty thousand animals were residing on every meter squared of the weapons, scientists wrote in their research on the discovery. The adjacent region was much poorer in life, with only eight thousand organisms on every meter squared. It is surprising that things that are designed to destroy everything are attracting so much marine organisms, explains Vedenin. It's evident how the natural world adjusts after a catastrophic event such as the second world war and how, in certain respects, life returns to the most risky areas. Artificial Structures as Ocean Environments Man-made constructions such as sunken vessels, offshore windfarms, oil rigs and undersea pipes can create alternatives, compensating for some of the removed marine environment. This research reveals that weapons could be similarly positive – the proliferation of marine organisms on those in the Bay of Lübeck is expected to be repeated elsewhere. Between 1946 and 1948, 1.6 million tonnes of munitions were disposed of off the Germany's shoreline. Countless of individuals placed them in boats; some were deposited in specific sites, others just dumped en route. This is the initial instance experts have documented how marine life has responded. Global Examples of Marine Transformation In the US, retired drilling platforms have become marine habitats Sunken ships from the World War I have become habitats for creatures along the Potomac in Maryland Military vehicle parts that have become home to reef-building organisms off Asan beach in Guam These locations become even more valuable for wildlife as the marine environments are increasingly depleted by fishing, bottom trawling and boat mooring. Sunken ships and munitions areas practically serve as sanctuaries – they are not national parks, but virtually any kind of anthropogenic disturbance is banned, says Vedenin. Therefore a lot of marine species that are otherwise rare or declining, such as the cod fish, are prospering. Future Considerations Wherever warfare has occurred in the last century, surrounding seas are usually littered with explosives, says Vedenin. Many millions of tons of volatile compounds remain in our oceans. The sites of these explosives are poorly mapped, in part because of sovereign limits, secret defense data and the fact that archives are buried in historic archives. They present an detonation and safety risk, as well as risk from the persistent emission of toxic chemicals. As the German government and other countries embark on clearing these relics, researchers aim to preserve the ecosystems that have developed around them. In the Lübeck Bay weapons are presently being extracted. We should replace these iron structures originating from weapons with certain less dangerous, various non-dangerous structures, like possibly man-made habitats, says Vedenin. He currently hopes that what occurs in the Bay of Lübeck sets a precedent for substituting structures after weapon clearance in different areas – because including the most harmful weaponry can become framework for ocean ecosystems.
