🔗 Share this article World War II Bombs, Torpedo Heads and Naval Mines: The Way Marine Life Flourishes on Abandoned Armaments In the slightly salty sea off the Germany's coast lies a wasteland of Nazi bombs, torpedoes and mines. Dumped from barges at the conclusion of the second world war and left behind, numerous munitions have accumulated over the decades. They comprise a decaying carpet on the shallow, silty ocean floor of the Bay of Lübeck in the western tip of the Baltic Sea. Over the years, the wartime weapons was ignored and forgotten about. A increasing amount of visitors flocked to the coastal areas and tranquil sea for water sports, kiteboarding and amusement parks. Beneath the surface, the weapons eroded. Researchers thought to see a lifeless zone, with no life because it was all toxic, says a scientist. When the initial researchers went investigating to see what they were doing to the ecosystem, some of us anticipated finding a lifeless zone, with no life because it was all toxic, says Andrey Vedenin. What they observed astonished them. Vedenin remembers his colleagues reacting with shock when the ROV first relayed pictures. It was a remarkable experience, he says. Numerous of ocean life had made their homes amid the munitions, creating a regenerated marine community denser than the ocean bottom nearby. This marine city was evidence to the resilience of marine life. Truly remarkable how much marine organisms we observe in locations that are supposed to be hazardous and harmful, he explains. In excess of 40 sea stars had gathered on to one accessible piece of explosive material. They were dwelling on metal shells, detonator compartments and storage boxes just a short distance from its volatile core. Fish, crabs, anemones and mussels were all found on the old munitions. You could compare it with a reef ecosystem in terms of the abundance of fauna that was present, states Vedenin. Unexpected Population Density An average of more than forty thousand organisms were dwelling on every meter squared of the munitions, experts documented in their study on the observation. The adjacent region was much sparser, with only eight thousand organisms on every square metre. It is ironic that items that are intended to kill all life are attracting so much marine organisms, states Vedenin. One can observe how the natural world evolves after a major disaster such as the World War II and how, in some way, marine life returns to the most risky places. Artificial Structures as Ocean Habitats Man-made structures such as shipwrecks, wind turbines, drilling platforms and undersea pipes can create replacements, compensating for some of the removed marine environment. This study reveals that weapons could be comparably beneficial – the explosion of marine organisms on those in the Lübeck Bay is expected to be repeated in different areas. Between the late 1940s and the post-war period, 1.6m tonnes of munitions were discarded off the Germany's shoreline. Thousands of workers transported them in vessels; a portion were deposited in allocated sites, others just thrown overboard en route. This is the first time researchers have studied how ocean organisms has responded. Worldwide Instances of Ocean Transformation In the United States, decommissioned drilling platforms have transformed into reef ecosystems Submerged vessels from the first world war have become homes for creatures along the Potomac River in the state of Maryland Tank tracks that have become habitat to reef-building organisms off Asan in Guam These locations become even more valuable for organisms as the seas are increasingly stripped by commercial fishing, bottom trawling and boat mooring. Shipwrecks and munitions areas effectively function as sanctuaries – they are not official reserves, but virtually any kind of human activity is banned, explains Vedenin. Therefore a many of marine species that are typically uncommon or declining, such as the Baltic cod, are prospering. Coming Issues Wherever armed conflict has occurred in the recent history, surrounding seas are typically containing explosives, states Vedenin. Millions of tonnes of volatile compounds rest in our seas. The positions of these munitions are insufficiently recorded, in part because of national borders, restricted military information and the situation that documents are stored in historic archives. They present an explosion and safety hazard, as well as danger from the continuous release of hazardous substances. As the German government and other countries start extracting these remains, experts hope to safeguard the marine communities that have established around them. In the Bay of Lübeck explosives are presently being extracted. It would be wise to replace these iron structures remaining from weapons with some less dangerous, some harmless structures, like maybe man-made habitats, states Vedenin. He currently wishes that what transpires in the Bay of Lübeck creates a example for replacing material after weapon clearance in other locations – because even the most harmful explosives can become foundation for ocean ecosystems.
