🔗 Share this article Nazi Explosives, Torpedo Heads and Naval Mines: How Ocean Creatures Flourishes on Abandoned Weapons In the slightly salty sea off the Germany's coast lies a wasteland of World War II explosives, torpedoes and naval mines. Discarded from vessels at the end of the World War II and neglected, thousands weapons have become matted together over the years. They comprise a corroding layer on the shallow, silty ocean floor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the Nazi arsenal was overlooked and forgotten about. A growing number of visitors flocked to the sandy beaches and tranquil sea for water sports, kiteboarding and amusement parks. Beneath the surface, the weapons eroded. Some of us anticipated to see a desert, with no life because it was all toxic, states a scientist. When the first scientists went investigating to see what they were doing to the ecosystem, researchers thought they would find a barren area, with nothing living there because it was all contaminated, states the lead researcher. What they discovered surprised them. Vedenin remembers his scientists reacting with shock when the submersible first transmitted footage. This was a remarkable experience, he notes. Numerous of ocean life had established habitats among the weapons, creating a revitalized habitat denser than the seabed surrounding it. This ocean community was proof to the resilience of marine life. Truly surprising how much life we discover in areas that are expected to be dangerous and dangerous, he explains. Over 40 sea stars had gathered on to one visible piece of explosive material. They were dwelling on steel casings, detonator compartments and storage boxes just centimetres from its dangerous content. Marine fish, crabs, anemones and bivalves were all found on the historic weapons. It resembles a marine reef in terms of the amount of creatures that was there, notes Vedenin. Surprising Population Density An average of more than 40,000 animals were living on every meter squared of the explosives, researchers documented in their research on the observation. The adjacent region was much sparser, with only 8,000 individuals on every meter squared. It is ironic that items that are meant to kill all life are attracting so much marine organisms, explains Vedenin. One can observe how nature adjusts after a major disaster such as the World War II and how, in some way, marine life finds its way to the most dangerous locations. Man-made Structures as Marine Habitats Man-made features such as sunken vessels, wind turbines, oil rigs and undersea pipes can create substitutes, replacing some of the lost marine environment. This research reveals that weapons could be equally beneficial – the bloom of life on those in the Bay of Lübeck is likely to be found in different areas. Between 1946 and the post-war period, 1.6 million tonnes of weapons were discarded off the German shoreline. Numerous of workers loaded them in boats; some were dropped in allocated locations, the remainder just discarded at sea during transport. This is the first time researchers have recorded how marine life has responded. Worldwide Instances of Ocean Adaptation In the United States, retired drilling platforms have become marine habitats Sunken ships from the World War I have become habitats for wildlife along the Potomac in the state of Maryland Military vehicle parts that have become home to reef-building organisms off Asan in the Pacific island These locations become even more valuable for wildlife as the oceans are increasingly denuded by commercial fishing, seafloor dredging and boat mooring. Sunken ships and weapons dump sites effectively serve as protected areas – they are not official reserves, but almost any kind of anthropogenic disturbance is prohibited, explains Vedenin. Therefore a many of organisms that are typically scarce or decreasing, such as the cod fish, are thriving. Coming Considerations Anywhere military conflict has happened in the past 100 years, nearby oceans are usually littered with munitions, states Vedenin. Many millions of tons of dangerous substances lie in our marine environments. The positions of these weapons are inadequately mapped, partly because of international boundaries, restricted defense data and the reality that documents are stored in historic archives. They pose an explosion and safety risk, as well as risk from the ongoing leakage of toxic chemicals. As Germany and other countries embark on removing these remains, experts aim to preserve the habitats that have developed around them. In the Bay of Lübeck weapons are already being removed. Researchers recommend substitute these iron structures remaining from munitions with some more secure, some non-dangerous materials, like possibly artificial reefs, states Vedenin. He currently hopes that what transpires in the Bay of Lübeck sets a model for substituting material after weapon clearance in different areas – because even the most harmful weaponry can become scaffolding for new life.
