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

In the brackish waters off the Germany's coast sits a wasteland of World War II explosives, torpedo heads and naval mines. Thrown off boats at the conclusion of the World War II and neglected, thousands weapons have fused into clusters over the years. They comprise a decaying blanket on the low-depth, silty seafloor of the Bay of Lübeck in the western tip of the Baltic Sea.

Over the decades, the explosive stockpile was ignored and forgotten about. A increasing amount of visitors traveled to the coastal areas and calm waters for water sports, kite surfing and entertainment venues. Below the waves, the weapons deteriorated.

Some of us expected to see a desert, with nothing living there because it was all toxic, explains Andrey Vedenin.

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

What they discovered astonished them. Vedenin recounts his team members exclaiming in amazement when the submersible first transmitted footage. That moment was a memorable occasion, he notes.

Numerous of marine animals had made their homes among the explosives, developing a revitalized ecosystem richer than the ocean bottom nearby.

This underwater metropolis was testament to the resilience of marine life. Indeed surprising how much marine organisms we observe in areas that are considered hazardous and harmful, he says.

Over 40 starfish had gathered on to one accessible chunk of explosive material. They were residing on steel casings, detonator compartments and carrying containers just a short distance from its explosive filling. Marine fish, crustaceans, anemones and bivalves were all found on the discarded explosives. It's similar to a reef ecosystem in terms of the amount of fauna that was present, states Vedenin.

Remarkable Creature Concentration

An average of more than 40,000 animals were living on every meter squared of the weapons, scientists reported in their research on the finding. The surrounding area was much less diverse, with only eight thousand creatures on every meter squared.

It is paradoxical that objects that are designed to destroy all life are drawing so much marine organisms, states Vedenin. It's evident how nature adjusts after a major disaster such as the World War II and how, in certain respects, marine life establishes itself to the most risky locations.

Artificial Features as Ocean Environments

Man-made features such as sunken vessels, offshore windfarms, drilling platforms and pipelines can create alternatives, restoring some of the lost marine environment. This research demonstrates that weapons could be comparably beneficial – the explosion of marine organisms on those in the Lübeck Bay is probable to be duplicated in different areas.

Between 1946 and 1948, 1.6 million tons of munitions were dumped off the German shoreline. Numerous of people loaded them in barges; a portion were deposited in designated sites, others just discarded at sea en route. This is the initial instance experts have recorded how marine life has responded.

Worldwide Instances of Ocean Transformation

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

These locations become even more crucial for organisms as the seas are increasingly stripped by fishing, seafloor dredging and boat mooring. Sunken ships and munitions areas effectively serve as refuges – they are not national parks, but virtually any kind of human activity is restricted, says Vedenin. Therefore a numerous of species that are otherwise uncommon or diminishing, such as the cod fish, are thriving.

Coming Issues

Anywhere military conflict has happened in the recent history, adjacent waters are typically containing munitions, states Vedenin. Many millions of tonnes of explosive material lie in our seas.

The sites of these munitions are poorly mapped, partly because of sovereign limits, secret defense data and the reality that documents are stored in historic archives. They pose an explosion and security hazard, as well as risk from the continuous leakage of poisonous compounds.

As Germany and other countries start removing these remains, experts aim to safeguard the ecosystems that have established in their vicinity. In the Bay of Lübeck munitions are currently being cleared.

We should substitute these steel remains left from weapons with some less dangerous, various non-dangerous materials, like perhaps man-made habitats, states Vedenin.

He now aspires that what transpires in the Bay of Lübeck establishes a model for replacing habitats after weapon clearance in different areas – because including the most destructive weaponry can become scaffolding for ocean ecosystems.
