World War II Explosives, Torpedo Heads and Mines: The Way Marine Life Thrives on Discarded Armaments

In the brackish sea off the Germany's shoreline rests a wasteland of World War II explosives, torpedoes and mines. Dumped from boats at the conclusion of the World War II and left behind, countless munitions have become matted together over the decades. They create a rusting layer on the shallow, silty ocean floor of the Lübeck Bay in the western part of the Baltic.

Over the years, the explosive stockpile was ignored and forgotten about. A growing number of visitors came to the coastal areas and calm waters for water sports, kite surfing and entertainment venues. Beneath the surface, the munitions decayed.

Researchers anticipated to see a desert, with nothing living there because it was all poisoned, explains a scientist.

When the team went looking to see what they were doing to the ecosystem, researchers anticipated finding a desert, with no organisms because it was all poisoned, explains the lead researcher.

What they observed amazed them. Vedenin recounts his team members shouting with surprise when the underwater vehicle first relayed pictures. This was a memorable occasion, he says.

Numerous of sea creatures had settled among the explosives, developing a renewed marine community more populous than the seabed nearby.

This ocean community was evidence to the tenacity of life. Truly remarkable how much marine organisms we find in locations that are supposed to be hazardous and risky, he explains.

In excess of 40 starfish had gathered on to one exposed fragment of explosive material. They were living on steel casings, ignition chambers and carrying containers just a short distance from its volatile core. Fish, crabs, anemones and mussels were all found on the old munitions. It resembles a reef ecosystem in terms of the amount of animal life that was there, states Vedenin.

Remarkable Population Density

An average of more than forty thousand animals were residing on every square metre of the weapons, researchers documented in their research on the finding. The nearby seabed was much less diverse, with only eight thousand creatures on every meter squared.

It is surprising that objects that are meant to kill everything are hosting so much marine organisms, says Vedenin. It's evident how the natural world adjusts after a devastating occurrence such as the World War II and how, in some way, life returns to the most hazardous locations.

Artificial Structures as Ocean Habitats

Artificial structures such as shipwrecks, offshore windfarms, oil rigs and pipelines can create replacements, compensating for some of the destroyed marine environment. This study demonstrates that munitions could be similarly beneficial – the explosion of life on those in the Bay of Lübeck is likely to be duplicated elsewhere.

Between 1946 and 1948, 1.6m tons of munitions were dumped off the German shoreline. Countless of people loaded them in boats; a portion were deposited in designated areas, others just discarded at sea en route. This is the first time experts have recorded how marine life has reacted.

Global Instances of Marine Transformation

  • In the United States, decommissioned oil and gas structures have turned into coral reefs
  • Sunken ships from the first world war have become homes for wildlife along the Potomac River in the state of Maryland
  • Tank tracks that have become environment to reef-building organisms off Asan in Guam

These locations become even more important for wildlife as the seas are increasingly stripped by commercial fishing, seafloor dredging and boat mooring. Sunken ships and munitions areas practically function as refuges – they are not national parks, but nearly any kind of anthropogenic disturbance is banned, states Vedenin. Therefore a many of species that are typically scarce or diminishing, such as the cod fish, are flourishing.

Coming Issues

Anywhere armed conflict has taken place in the recent history, adjacent waters are typically containing munitions, explains Vedenin. Many millions of tons of volatile compounds lie in our seas.

The locations of these munitions are inadequately mapped, in part because of national borders, restricted defense data and the reality that records are stored in historical records. They create an explosion and safety danger, as well as threat from the persistent leakage of toxic chemicals.

As the German government and additional nations embark on removing these relics, experts hope to safeguard the habitats that have developed nearby. In the Bay of Lübeck weapons are presently being extracted.

We should replace these iron structures remaining from weapons with some less dangerous, various harmless structures, like maybe man-made habitats, states Vedenin.

He presently hopes that what occurs in Lübeck sets a model for substituting structures after explosive extraction in different areas – because even the most destructive weaponry can become foundation for new life.
