Nazi Bombs, Torpedo Heads and Mines: How Marine Life Flourishes on Abandoned Armaments

In the brackish waters off the German shoreline sits a graveyard of World War II explosives, torpedo heads and mines. Dumped from vessels at the end of the World War II and neglected, countless explosives have accumulated over the decades. They form a corroding carpet on the low-depth, 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 neglected. A increasing amount of visitors traveled to the coastal areas and calm waters for water sports, kiteboarding and amusement parks. Beneath the surface, the munitions eroded.

Some of us thought to see a barren area, with no organisms because it was all toxic, states the lead researcher.

When the team went searching to see what they were affecting to the marine environment, the team expected to see a desert, with no life because it was all contaminated, says a scientist.

What they observed surprised them. Vedenin remembers his scientists reacting with shock when the submersible first sent the images back. This was a remarkable experience, he notes.

Thousands of sea creatures had established habitats amid the munitions, forming a regenerated marine community more populous than the seabed nearby.

This ocean community was testament to the tenacity of marine life. Indeed remarkable how much marine organisms we discover in places that are considered dangerous and dangerous, he says.

More than 40 sea stars had clustered on to one exposed piece of TNT. They were residing on iron containers, fuse pockets and carrying containers just a short distance from its volatile core. Fish, crabs, sea anemones and mussels were all observed on the discarded explosives. It resembles a reef ecosystem in terms of the quantity of fauna that was there, says Vedenin.

Surprising Creature Concentration

An average of more than 40,000 animals were residing on every square metre of the explosives, scientists reported in their study on the discovery. The adjacent region was much sparser, with only eight thousand organisms on every square metre.

It is paradoxical that items that are intended to eliminate all life are attracting so much marine organisms, states Vedenin. You can see how nature adapts after a major disaster such as the second world war and how, in certain respects, marine life establishes itself to the most risky locations.

Artificial Features as Marine Habitats

Man-made features such as shipwrecks, wind turbines, oil rigs and pipelines can offer substitutes, restoring some of the lost habitat. This investigation demonstrates that weapons could be similarly beneficial – the explosion of marine organisms on those in the Bay of Lübeck is probable to be found elsewhere.

Between 1946 and 1948, 1.6m tons of arms were disposed of off the Germany's coast. Numerous of individuals placed them in vessels; a portion were dropped in designated locations, others just discarded at sea en route. This is the initial instance scientists have recorded how marine life has responded.

Worldwide Instances of Marine Adaptation

• In the United States, decommissioned energy installations have transformed into coral reefs
• Shipwrecks from the World War I have become environments for wildlife along the Potomac in Maryland
• Military vehicle parts that have become environment to coral off Asan beach in the Pacific island

These locations become even more important for wildlife as the oceans are increasingly denuded by fishing, bottom trawling and anchoring. Shipwrecks and weapons dump sites essentially function as sanctuaries – they are not official reserves, but virtually any kind of human activity is banned, states Vedenin. Therefore a numerous of organisms that are typically scarce or decreasing, such as the Baltic cod, are thriving.

Coming Considerations

Wherever military conflict has happened in the recent history, nearby oceans are typically strewn with explosives, states Vedenin. Many millions of tons of dangerous substances remain in our seas.

The locations of these explosives are insufficiently mapped, in part because of national borders, restricted military information and the fact that archives are stored in historical records. They present an detonation and security hazard, as well as risk from the continuous leakage of toxic chemicals.

As Germany and different states begin removing these remains, experts plan to safeguard the habitats that have formed around them. In the Bay of Lübeck explosives are currently being removed.

We should substitute these metal carcasses originating from weapons with certain less dangerous, some safe objects, like perhaps concrete structures, suggests Vedenin.

He currently aspires that what happens in Lübeck establishes a precedent for replacing habitats after explosive extraction in different areas – because also the most destructive weaponry can become framework for ocean ecosystems.
