World War II Explosives, Torpedo Heads and Mines: How Ocean Creatures Flourishes on Dumped Armaments

In the slightly salty waters off the Germany's shoreline lies a wasteland of World War II explosives, torpedo heads and mines. Dumped from vessels at the conclusion of the World War II and forgotten about, numerous munitions have accumulated over the years. They create a decaying layer on the low-depth, silty seafloor of the Lübeck Bay in the western tip of the Baltic.

Over the decades, the wartime weapons was ignored and forgotten about. A growing number of tourists traveled to the coastal areas and calm waters for jetskiing, kite surfing and amusement parks. Underwater, the weapons decayed.

Some of us thought to see a desert, with no organisms because it was all contaminated, says the lead researcher.

When the first scientists went searching to see what they were doing to the marine environment, some of us thought they would find a barren area, with no life because it was all toxic, explains the lead researcher.

What they found astonished them. Vedenin recalls his colleagues exclaiming in amazement when the submersible first relayed pictures. That moment was a memorable occasion, he recalls.

Thousands of marine animals had established habitats amid the explosives, developing a revitalized marine community denser than the seabed nearby.

This marine city was proof to the tenacity of life. Indeed surprising how much life we find in places that are supposed to be dangerous and dangerous, he states.

In excess of 40 sea stars had clustered on to one exposed chunk of TNT. They were dwelling on iron containers, detonator compartments and carrying containers just a short distance from its explosive filling. Marine fish, crustaceans, anemones and mussels were all observed on the old munitions. It resembles a marine reef in terms of the abundance of creatures that was there, says Vedenin.

Remarkable Population Density

An average of more than forty thousand animals were living on every square metre of the weapons, experts documented in their paper on the discovery. The adjacent region was much poorer in life, with only eight thousand individuals on every meter squared.

It is ironic that items that are designed to kill all life are attracting so much marine organisms, explains Vedenin. It's evident how the natural world adapts after a major disaster such as the second world war and how, in some way, life finds its way to the most risky locations.

Artificial Features as Marine Habitats

Man-made constructions such as sunken vessels, wind turbines, drilling platforms and pipelines can offer replacements, restoring some of the destroyed habitat. This investigation shows that weapons could be equally beneficial – the explosion of life on those in the Bay of Lübeck is likely to be duplicated in other locations.

Between the late 1940s and 1948, 1.6m tonnes of weapons were dumped off the Germany's shoreline. Numerous of individuals placed them in boats; a portion were deposited in designated locations, the remainder just dumped en route. This is the initial instance researchers have documented how marine life has adapted.

Worldwide Instances of Marine Adaptation

• In the US, retired energy installations have transformed into marine habitats
• Submerged vessels from the World War I have become habitats for wildlife along the Potomac River in Maryland
• Military vehicle parts that have become home to reef-building organisms off Asan beach in Guam

These areas become even more crucial for marine life as the marine environments are increasingly stripped by commercial fishing, bottom trawling and anchoring. Sunken ships and munitions areas practically function as refuges – they are not national parks, but virtually any kind of anthropogenic disturbance is banned, explains Vedenin. Therefore a numerous of species that are otherwise uncommon or declining, such as the Baltic cod, are flourishing.

Future Factors

Wherever military conflict has occurred in the recent history, surrounding seas are typically containing weapons, says Vedenin. Millions of tonnes of explosive material remain in our marine environments.

The locations of these explosives are inadequately documented, partially because of international boundaries, restricted armed forces records and the reality that documents are hidden in historical records. They present an detonation and safety risk, as well as risk from the continuous release of toxic chemicals.

As Germany and additional nations begin removing these artifacts, researchers hope to protect the habitats that have formed in their vicinity. In the Bay of Lübeck explosives are currently being extracted.

We should replace these steel remains remaining from munitions with certain more secure, some harmless structures, like possibly artificial reefs, says Vedenin.

He presently aspires that what transpires in Lübeck creates a model for replacing material after explosive extraction elsewhere – because even the most destructive explosives can become framework for new life.
