Nazi Munitions, Torpedoes and Mines: The Way Marine Life Flourishes on Discarded Armaments

In the slightly salty sea off the German shoreline sits a graveyard of Nazi bombs, torpedo heads and naval mines. Thrown off boats at the end of the second world war and left behind, countless explosives have accumulated over the years. They comprise a decaying blanket on the shallow, muddy ocean floor of the Lübeck Bay in the western part of the Baltic Sea.

Over the decades, the explosive stockpile was overlooked and forgotten about. A growing number of tourists traveled to the coastal areas and calm waters for jetskiing, kiteboarding and entertainment venues. Underwater, the weapons eroded.

Some of us thought to see a barren area, with no life because it was all poisoned, explains the lead researcher.

When the initial researchers went looking to see what they were affecting to the ecosystem, some of us thought they would find a lifeless zone, with nothing living there because it was all contaminated, says the lead researcher.

What they discovered astonished them. Vedenin recounts his scientists shouting with surprise when the underwater vehicle first sent the images back. This was a remarkable experience, he recalls.

Numerous of ocean life had established habitats amid the munitions, creating a revitalized habitat denser than the sea floor surrounding it.

This underwater metropolis was evidence to the tenacity of life. Truly remarkable how much marine organisms we observe in locations that are expected to be dangerous and risky, he states.

In excess of 40 sea stars had gathered on to one visible piece of explosive material. They were living on metal shells, detonator compartments and transport cases just centimetres from its volatile core. Fish, crabs, anemones and bivalves were all found on the discarded explosives. You could compare it with a coral reef in terms of the abundance of creatures that was there, says Vedenin.

Unexpected Population Density

An mean of more than forty thousand organisms were residing on every square metre of the explosives, experts documented in their study on the observation. The adjacent region was much less diverse, with only eight thousand creatures on every meter squared.

It is paradoxical that items that are designed to kill everything are drawing so much life, states Vedenin. One can observe how nature adjusts after a major disaster such as the second world war and how, in some way, marine life returns to the most hazardous locations.

Man-made Structures as Ocean Habitats

Man-made structures such as sunken vessels, offshore windfarms, oil rigs and undersea pipes can provide replacements, restoring some of the lost marine environment. This investigation demonstrates that munitions could be equally beneficial – the proliferation of marine organisms on those in the Bay of Lübeck is expected to be found elsewhere.

Between 1946 and 1948, 1.6 million tons of arms were dumped off the German shoreline. Numerous of people loaded them in boats; some were dropped in specific locations, the remainder just discarded at sea while traveling. This is the initial instance scientists have recorded how ocean organisms has responded.

Worldwide Instances of Marine Adaptation

• In the United States, decommissioned oil and gas structures have transformed into coral reefs
• Sunken ships from the first world war have become homes for creatures along the Potomac in Maryland
• Military vehicle parts that have become home to coral off Asan in the Pacific island

These places become even more important for organisms as the marine environments are increasingly stripped by fishing, seafloor dredging and anchoring. Shipwrecks and explosive disposal locations essentially act as protected areas – they are not national parks, but nearly any kind of human activity is restricted, says Vedenin. Consequently a lot of marine species that are otherwise scarce or declining, such as the cod fish, are thriving.

Coming Issues

Anywhere warfare has occurred in the last century, adjacent waters are often containing weapons, says Vedenin. Millions of tonnes of explosive material rest in our oceans.

The locations of these weapons are insufficiently documented, partially because of sovereign limits, classified armed forces records and the situation that archives are hidden in historical records. They present an explosion and security hazard, as well as threat from the ongoing emission of hazardous substances.

As Germany and different states begin clearing these artifacts, scientists hope to protect the ecosystems that have formed nearby. In the Lübeck Bay weapons are currently being removed.

We should substitute these metal carcasses left from weapons with certain safer, various non-dangerous structures, like possibly man-made habitats, states Vedenin.

He presently wishes that what occurs in the Bay of Lübeck establishes a precedent for replacing structures after munitions removal in different areas – because even the most destructive armaments can become framework for new life.
