World War II Munitions, Torpedoes and Mines: The Way Marine Life Flourishes on Abandoned Armaments

In the slightly salty sea off the German shoreline lies a wasteland of Nazi bombs, torpedoes and mines. Dumped from boats at the conclusion of the second world war and forgotten about, thousands munitions have fused into clusters over the years. They create a decaying carpet on the shallow, silty seafloor of the Lübeck Bay in the western part of the Baltic.

Over the years, the explosive stockpile was overlooked and neglected. A increasing amount of visitors came to the sandy beaches and tranquil sea for jetskiing, kiteboarding and entertainment venues. Beneath the surface, the weapons eroded.

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

When the initial researchers went searching to see what they were doing to the marine environment, some of us thought they would find a desert, with nothing living there because it was all toxic, states the lead researcher.

What they observed surprised them. Vedenin remembers his scientists exclaiming in amazement when the ROV first sent the images back. This was a great moment, he notes.

Thousands of sea creatures had settled on the explosives, developing a revitalized marine community denser than the sea floor surrounding it.

This marine city was testament to the resilience of life. Indeed remarkable how much life we find in locations that are supposed to be hazardous and dangerous, he explains.

Over 40 starfish had piled on to one accessible chunk of TNT. They were living on steel casings, ignition chambers and storage boxes just a short distance from its dangerous content. Fish, crabs, sea anemones and bivalves were all discovered on the old munitions. It's similar to a reef ecosystem in terms of the abundance of animal life that was inhabiting the area, states Vedenin.

Remarkable Creature Concentration

An average of more than 40,000 animals were living on every meter squared of the explosives, researchers wrote in their research on the finding. The nearby seabed was much poorer in life, with only 8,000 creatures on every square metre.

It is paradoxical that items that are designed to kill everything are hosting so much marine organisms, says Vedenin. It's evident how nature adapts after a catastrophic event such as the World War II and how, in certain respects, life finds its way to the most risky locations.

Man-made Structures as Ocean Habitats

Man-made structures such as shipwrecks, offshore windfarms, drilling platforms and pipelines can provide replacements, restoring some of the destroyed marine environment. This study demonstrates that munitions could be similarly advantageous – the bloom of marine organisms on those in the Bay of Lübeck is expected to be duplicated in other locations.

Between the late 1940s and the post-war period, 1.6m tons of munitions were dumped off the Germany's shoreline. Thousands of workers loaded them in vessels; some were deposited in designated locations, the remainder just dumped while traveling. This is the initial instance scientists have studied how marine life has responded.

Worldwide Instances of Marine Adaptation

  • In the US, decommissioned energy installations have become marine habitats
  • Submerged vessels from the World War I have become habitats for marine life along the Potomac River in Maryland
  • Tank tracks that have become habitat to reef-building organisms off Asan beach in the Pacific island

These areas become even more important for organisms as the marine environments are increasingly depleted by commercial fishing, seafloor dredging and boat mooring. Sunken ships and munitions areas essentially serve as refuges – they are not national parks, but nearly any kind of anthropogenic disturbance is restricted, explains Vedenin. Therefore a many of species that are typically rare or decreasing, such as the Baltic cod, are thriving.

Future Issues

Wherever warfare has happened in the last century, adjacent waters are usually littered with weapons, says Vedenin. Millions of tonnes of volatile compounds lie in our seas.

The locations of these explosives are insufficiently documented, partly because of international boundaries, secret military information and the fact that archives are buried in old files. They pose an explosion and safety danger, as well as risk from the persistent leakage of poisonous compounds.

As the German government and additional nations embark on extracting these artifacts, researchers hope to preserve the ecosystems that have formed in their vicinity. In the Lübeck Bay munitions are presently being removed.

Researchers recommend replace these steel remains left from munitions with certain more secure, some harmless structures, like maybe man-made habitats, suggests Vedenin.

He presently hopes that what occurs in Lübeck creates a model for replacing material after munitions removal in different areas – because including the most damaging armaments can become framework for new life.
