Nazi Bombs, Torpedo Heads and Naval Mines: The Way Marine Life Thrives on Dumped Armaments

In the slightly salty sea off the Germany's shoreline rests a collection of World War II explosives, torpedoes and mines. Thrown off vessels at the conclusion of the World War II and neglected, thousands weapons have become matted together over the years. They comprise a corroding blanket on the low-depth, muddy ocean floor of the Bay of Lübeck in the western tip of the Baltic.

Over the decades, the explosive stockpile was ignored and forgotten about. A growing number of visitors flocked to the coastal areas and calm waters for water sports, kiteboarding and amusement parks. Beneath the surface, the weapons eroded.

We initially expected to see a desert, with nothing living there because it was all contaminated, states the lead researcher.

When the first scientists went searching to see what they were doing to the marine environment, researchers anticipated finding a desert, with no life because it was all poisoned, explains a scientist.

What they discovered amazed them. Vedenin recounts his team members exclaiming in amazement when the underwater vehicle first relayed pictures. This was a remarkable experience, he says.

Countless of ocean life had established habitats among the weapons, developing a renewed ecosystem more populous than the seabed surrounding it.

This underwater metropolis was proof to the tenacity of marine life. It is actually surprising how much life we find in areas that are supposed to be dangerous and dangerous, he says.

Over 40 sea stars had gathered on to one visible chunk of TNT. They were living on metal shells, ignition chambers and carrying containers just a short distance from its volatile core. Marine fish, crustaceans, sea anemones and mussels were all found on the discarded explosives. It's similar to a reef ecosystem in terms of the quantity of fauna that was present, says Vedenin.

Unexpected Creature Concentration

An average of more than 40,000 organisms were living on every meter squared of the weapons, experts documented in their study on the discovery. The adjacent region was much sparser, with only 8,000 individuals on every meter squared.

It is ironic that objects that are intended to eliminate everything are attracting so much marine organisms, explains Vedenin. One can observe how nature adjusts after a devastating occurrence such as the World War II and how, in certain respects, life returns to the most dangerous places.

Man-made Features as Marine Environments

Artificial features such as shipwrecks, offshore windfarms, drilling platforms and undersea pipes can create alternatives, replacing some of the lost habitat. This study shows that weapons could be comparably beneficial – the proliferation of life on those in the Lübeck Bay is probable to be found elsewhere.

Between the late 1940s and 1948, 1.6 million tonnes of munitions were disposed of off the German shoreline. Numerous of people transported them in boats; some were placed in specific locations, the remainder just dumped while traveling. This is the initial instance experts have documented how ocean organisms has reacted.

Global Examples of Marine Adaptation

• In the United States, decommissioned oil and gas structures have transformed into coral reefs
• Shipwrecks from the World War I have become habitats for wildlife along the Potomac in the state of Maryland
• Military vehicle parts that have become habitat to reef-building organisms off Asan in the Pacific island

These locations become even more crucial for wildlife as the oceans are increasingly depleted by commercial fishing, seafloor dredging and anchoring. Shipwrecks and munitions areas practically function as sanctuaries – they are not national parks, but nearly any kind of human activity is prohibited, states Vedenin. Therefore a many of organisms that are otherwise uncommon or decreasing, such as the cod fish, are flourishing.

Future Considerations

Anywhere armed conflict has occurred in the recent history, nearby oceans are often strewn with explosives, says Vedenin. Many millions of tons of dangerous substances remain in our oceans.

The sites of these munitions are insufficiently recorded, in part because of international boundaries, secret military information and the situation that archives are buried in historic archives. They create an detonation and security risk, as well as threat from the ongoing release of poisonous compounds.

As the German government and different states start extracting these relics, scientists hope to preserve the ecosystems that have formed in their vicinity. In the Lübeck Bay weapons are currently being extracted.

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

He presently aspires that what transpires in the Bay of Lübeck creates a model for substituting material after munitions removal in different areas – because also the most destructive armaments can become scaffolding for ocean ecosystems.
