🔗 Share this article World War II Explosives, Torpedo Heads and Naval Mines: The Way Marine Life Thrives on Abandoned Armaments In the slightly salty sea off the German coast rests a wasteland of Nazi bombs, torpedo heads and mines. Thrown off barges at the conclusion of the second world war and neglected, thousands weapons have fused into clusters over the decades. They form a rusting carpet on the low-depth, silty seafloor of the Lübeck Bay in the western part of the Baltic Sea. Over the years, the Nazi arsenal was overlooked and forgotten about. A increasing amount of visitors flocked to the sandy beaches and tranquil sea for jetskiing, kite surfing and amusement parks. Underwater, the munitions decayed. Some of us anticipated to see a desert, with no organisms because it was all contaminated, states a scientist. When the team went searching to see what they were doing to the marine environment, some of us anticipated finding a lifeless zone, with no organisms because it was all toxic, states the lead researcher. What they discovered amazed them. Vedenin recalls his scientists exclaiming in amazement when the submersible first sent the images back. That moment was a remarkable experience, he notes. Numerous of ocean life had settled among the explosives, creating a regenerated marine community denser than the sea floor surrounding it. This underwater metropolis was proof to the persistence of life. Truly remarkable how much life we find in places that are expected to be toxic and dangerous, he says. More than 40 sea stars had piled on to one visible chunk of explosive material. They were residing on steel casings, detonator compartments and carrying containers just a short distance from its explosive filling. Marine fish, crabs, sea anemones and bivalves were all found on the discarded explosives. You could compare it with a reef ecosystem in terms of the abundance of animal life that was there, notes Vedenin. Remarkable Population Density An average of more than forty thousand animals were dwelling on every square metre of the munitions, researchers wrote in their paper on the finding. The surrounding area was much sparser, with only eight thousand creatures on every meter squared. It is paradoxical that things that are intended to kill all life are attracting so much marine organisms, says Vedenin. It's evident how nature evolves after a catastrophic event such as the second world war and how, in some way, life returns to the most risky locations. Man-made Structures as Marine Habitats Man-made constructions such as shipwrecks, wind turbines, drilling platforms and undersea pipes can create alternatives, restoring some of the destroyed habitat. This investigation demonstrates that weapons could be comparably positive – the proliferation of marine organisms on those in the Bay of Lübeck is expected to be repeated in other locations. Between 1946 and 1948, 1.6m tons of weapons were discarded off the German coast. Numerous of workers transported them in boats; a portion were deposited in designated locations, others just discarded at sea en route. This is the initial instance researchers have documented how marine life has responded. Global Examples of Ocean Adaptation In the US, retired drilling platforms have transformed into reef ecosystems Shipwrecks from the first world war have become habitats for marine life along the Potomac in the state of Maryland Tank tracks that have become habitat to reef-building organisms off Asan beach in Guam These areas become even more important for marine life as the seas are increasingly stripped by commercial fishing, seafloor dredging and anchoring. Shipwrecks and munitions areas effectively act as sanctuaries – they are not national parks, but almost any kind of human activity is banned, states Vedenin. Consequently a numerous of marine species that are usually scarce or declining, such as the Baltic cod, are thriving. Coming Issues Wherever warfare has taken place in the past 100 years, surrounding seas are typically containing weapons, says Vedenin. Millions of tonnes of volatile compounds remain in our marine environments. The sites of these munitions are insufficiently recorded, partly because of international boundaries, classified armed forces records and the fact that documents are buried in old files. They pose an explosion and security risk, as well as threat from the ongoing release of hazardous substances. As Germany and additional nations embark on clearing these relics, experts plan to protect the marine communities that have formed nearby. In the Lübeck Bay explosives are currently being cleared. We should replace these iron structures left from weapons with some more secure, some non-dangerous objects, like perhaps artificial reefs, says Vedenin. He now wishes that what occurs in Lübeck sets a precedent for substituting habitats after explosive extraction in other locations – because including the most harmful weaponry can become foundation for ocean ecosystems.
