🔗 Share this article World War II Bombs, Torpedo Heads and Naval Mines: The Way Marine Life Flourishes on Discarded Weapons In the slightly salty sea off the Germany's coast lies a wasteland of World War II explosives, torpedo heads and mines. Discarded from vessels at the conclusion of the second world war and left behind, numerous explosives have accumulated over the years. They create a corroding carpet on the shallow, muddy ocean floor of the Bay of Lübeck in the western part of the Baltic Sea. Over the decades, the explosive stockpile was ignored and forgotten about. A growing number of visitors flocked to the sandy beaches and calm waters for jetskiing, kite surfing and entertainment venues. Beneath the surface, the weapons decayed. Researchers expected to see a barren area, with nothing living there because it was all poisoned, explains Andrey Vedenin. When the initial researchers went searching to see what they were affecting to the marine environment, the team thought they would find a barren area, with no organisms because it was all contaminated, states Andrey Vedenin. What they found amazed them. Vedenin remembers his colleagues shouting with surprise when the submersible first transmitted footage. This was a memorable occasion, he recalls. Numerous of ocean life had established habitats amid the weapons, developing a revitalized marine community more populous than the sea floor surrounding it. This ocean community was evidence to the persistence of marine life. Indeed astonishing how much marine organisms we observe in areas that are considered hazardous and risky, he explains. More than 40 starfish had piled on to one visible piece of TNT. They were living on iron containers, ignition chambers and transport cases just a short distance from its volatile core. Fish, crabs, anemones and bivalves were all discovered on the historic weapons. It's similar to a reef ecosystem in terms of the abundance of animal life that was present, notes Vedenin. Unexpected Population Density An mean of more than forty thousand animals were dwelling on every square metre of the explosives, experts documented in their study on the finding. The adjacent region was much sparser, with only eight thousand creatures on every meter squared. It is ironic that things that are intended to destroy all life are hosting so much life, states Vedenin. You can see how the natural world adjusts after a catastrophic event such as the second world war and how, in some way, marine life returns to the most hazardous areas. Man-made Structures as Ocean Habitats Man-made constructions such as sunken vessels, wind turbines, drilling platforms and pipelines can provide replacements, replacing some of the lost habitat. This study shows that weapons could be equally advantageous – the explosion of life on those in the Lübeck Bay is likely to be found elsewhere. Between 1946 and the post-war period, 1.6 million tons of weapons were discarded off the German shoreline. Numerous of workers transported them in boats; some were placed in designated areas, the remainder just dumped while traveling. This is the first time scientists have studied how marine life has responded. Worldwide Instances of Ocean Adaptation In the US, decommissioned oil and gas structures have become marine habitats Sunken ships from the World War I have become habitats for wildlife along the Potomac in Maryland Tank tracks that have become environment to coral off Asan beach in Guam These locations become even more important for wildlife as the seas are increasingly denuded by fishing, seafloor dredging and boat mooring. Sunken ships and munitions areas practically function as sanctuaries – they are not national parks, but virtually any kind of anthropogenic disturbance is prohibited, explains Vedenin. Consequently a numerous of species that are usually scarce or declining, such as the cod fish, are prospering. Future Issues Wherever warfare has taken place in the past 100 years, nearby oceans are often littered with munitions, states Vedenin. Millions of tonnes of dangerous substances rest in our oceans. The positions of these explosives are poorly mapped, partially because of national borders, classified military information and the reality that archives are stored in old files. They create an explosion and security hazard, as well as threat from the persistent emission of poisonous compounds. As the German government and different states start extracting these relics, experts aim to preserve the marine communities that have established in their vicinity. In the Lübeck Bay explosives are currently being cleared. Researchers recommend substitute these iron structures remaining from weapons with some less dangerous, various safe objects, like perhaps concrete structures, suggests Vedenin. He currently hopes that what transpires in Lübeck creates a model for replacing material after weapon clearance in other locations – because even the most destructive weaponry can become scaffolding for ocean ecosystems.
