🔗 Share this article Nazi Munitions, Torpedo Heads and Mines: The Way Ocean Creatures Flourishes on Discarded Weapons In the brackish sea off the German shoreline sits a collection of World War II explosives, torpedoes and mines. Dumped from barges at the end of the World War II and neglected, thousands munitions have fused into clusters over the decades. They create a corroding blanket on the low-depth, silty ocean floor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the wartime weapons was ignored and forgotten about. A growing number of visitors came to the sandy beaches and calm waters for jetskiing, kiteboarding and amusement parks. Beneath the surface, the weapons decayed. We initially thought to see a barren area, with no life because it was all toxic, explains a scientist. When the initial researchers went investigating to see what they were doing to the marine environment, some of us expected to see a barren area, with no life because it was all poisoned, says Andrey Vedenin. What they found astonished them. Vedenin remembers his team members shouting with surprise when the ROV first sent the images back. This was a great moment, he says. Thousands of sea creatures had established habitats on the munitions, forming a regenerated ecosystem denser than the ocean bottom nearby. This ocean community was testament to the tenacity of life. Truly astonishing how much marine organisms we find in places that are supposed to be toxic and dangerous, he explains. In excess of 40 starfish had gathered on to one accessible chunk of TNT. They were dwelling on iron containers, detonator compartments and transport cases just a short distance from its explosive filling. Fish, crabs, sea anemones and mussels were all observed on the old munitions. You could compare it with a coral reef in terms of the abundance of animal life that was inhabiting the area, states Vedenin. Remarkable Population Density An mean of more than 40,000 animals were dwelling on every square metre of the weapons, scientists reported in their research on the observation. The nearby seabed was much poorer in life, with only eight thousand individuals on every square metre. It is surprising that items that are designed to destroy everything are drawing so much marine organisms, states Vedenin. You can see how the natural world adjusts after a catastrophic event such as the second world war and how, in certain respects, life finds its way to the most dangerous areas. Man-made Structures as Marine Environments Man-made structures such as sunken vessels, offshore windfarms, drilling platforms and pipelines can provide substitutes, compensating for some of the removed marine environment. This investigation reveals that explosives could be equally advantageous – the bloom of life on those in the Lübeck Bay is probable to be duplicated in different areas. Between 1946 and the post-war period, 1.6 million tonnes of weapons were dumped off the Germany's shoreline. Countless of workers placed them in barges; a portion were dropped in designated sites, the remainder just dumped while traveling. This is the first time scientists have recorded how ocean organisms has adapted. Global Examples of Ocean Transformation In the United States, decommissioned oil and gas structures have turned into reef ecosystems Submerged vessels from the first world war have become environments for wildlife along the Potomac River in the state of Maryland Military vehicle parts that have become home to coral off Asan beach in the Pacific island These locations become even more crucial for wildlife as the seas are increasingly stripped by commercial fishing, bottom trawling and boat mooring. Shipwrecks and explosive disposal locations effectively function as protected areas – they are not national parks, but almost any kind of human activity is banned, states Vedenin. As a result a numerous of species that are typically rare or decreasing, such as the Baltic cod, are flourishing. Coming Considerations Wherever warfare has occurred in the last century, surrounding seas are usually containing explosives, states Vedenin. Many millions of tonnes of dangerous substances lie in our seas. The locations of these munitions are insufficiently mapped, in part because of sovereign limits, restricted military information and the fact that archives are buried in historic archives. They pose an explosion and safety danger, as well as danger from the continuous emission of toxic chemicals. As Germany and additional nations begin extracting these remains, experts aim to protect the ecosystems that have formed in their vicinity. In the Lübeck Bay explosives are already being extracted. Researchers recommend replace these iron structures remaining from weapons with some safer, various non-dangerous structures, like maybe artificial reefs, says Vedenin. He now wishes that what transpires in the Bay of Lübeck sets a model for replacing structures after weapon clearance elsewhere – because even the most damaging explosives can become foundation for marine organisms.
