🔗 Share this article World War II Explosives, Torpedoes and Mines: How Marine Life Flourishes on Dumped Weapons In the slightly salty waters off the Germany's shoreline sits a wasteland of World War II explosives, torpedoes and mines. Thrown off vessels at the end of the World War II and left behind, countless munitions have become matted together over the decades. They form a decaying carpet on the low-depth, silty ocean floor of the Bay of Lübeck in the western tip of the Baltic Sea. Over the decades, the Nazi arsenal was overlooked and forgotten about. A growing number of tourists came to the sandy beaches and tranquil sea for water sports, kite surfing and entertainment venues. Beneath the surface, the munitions deteriorated. Some of us thought to see a desert, with no life because it was all toxic, says a scientist. When the first scientists went looking to see what they were affecting to the ecosystem, some of us expected to see a barren area, with no life because it was all contaminated, says a scientist. What they observed amazed them. Vedenin remembers his colleagues reacting with shock when the submersible first transmitted footage. That moment was a remarkable experience, he recalls. Thousands of sea creatures had settled amid the munitions, developing a regenerated habitat more populous than the sea floor surrounding it. This marine city was evidence to the persistence of life. Indeed astonishing how much marine organisms we find in places that are considered dangerous and harmful, he says. In excess of 40 starfish had gathered on to one accessible fragment of explosive material. They were living on steel casings, detonator compartments and carrying containers just a short distance from its volatile core. Marine fish, crustaceans, anemones and bivalves were all discovered on the old munitions. You could compare it with a marine reef in terms of the abundance of fauna that was there, notes Vedenin. Surprising Creature Concentration An average of more than forty thousand creatures were living on every square metre of the explosives, researchers documented in their paper on the discovery. The adjacent region was much poorer in life, with only 8,000 organisms on every meter squared. It is surprising that objects that are meant to destroy everything are drawing so much marine organisms, says Vedenin. You can see how nature evolves after a major disaster such as the World War II and how, in some way, life finds its way to the most risky locations. Man-made Features as Marine Habitats Artificial structures such as shipwrecks, offshore windfarms, oil rigs and undersea pipes can offer replacements, compensating for some of the lost habitat. This research demonstrates that munitions could be comparably beneficial – the explosion of life on those in the Bay of Lübeck is probable to be found in other locations. Between 1946 and 1948, 1.6m tons of weapons were discarded off the German coast. Numerous of people transported them in barges; a portion were placed in specific areas, the remainder just discarded at sea en route. This is the initial instance experts have documented how marine life has reacted. Worldwide Examples of Ocean Adaptation In the US, decommissioned oil and gas structures have transformed into reef ecosystems Shipwrecks from the World War I have become environments for marine life along the Potomac River in Maryland Tank tracks that have become environment to reef-building organisms off Asan in the Pacific island These places become even more important for wildlife as the seas are increasingly stripped by commercial fishing, seafloor dredging and anchoring. Sunken ships and munitions areas practically act as refuges – they are not national parks, but almost any kind of anthropogenic disturbance is banned, explains Vedenin. Consequently a numerous of species that are usually rare or decreasing, such as the cod fish, are prospering. Future Considerations Wherever armed conflict has taken place in the recent history, surrounding seas are usually strewn with munitions, explains Vedenin. Many millions of tonnes of volatile compounds remain in our oceans. The positions of these munitions are poorly mapped, in part because of sovereign limits, secret military information and the situation that archives are hidden in historical records. They present an explosion and security danger, as well as danger from the ongoing release of poisonous compounds. As the German government and additional nations begin extracting these remains, researchers hope to safeguard the ecosystems that have established in their vicinity. In the Bay of Lübeck munitions are presently being removed. It would be wise to replace these metal carcasses left from munitions with some safer, various harmless materials, like maybe artificial reefs, suggests Vedenin. He presently aspires that what transpires in the Bay of Lübeck establishes a model for substituting material after munitions removal in other locations – because including the most damaging explosives can become foundation for new life.
