There's a "lost city" in the depths of the ocean, a place like no other: ScienceAlert & More Latest News Here - Up Jobs

Near the summit of an underwater mountain west of the Mid-Atlantic Ridge, a rugged landscape of towers rises out of the darkness.

Its creamy carbon walls and pillars appear an eerie blue in the light of a remote-controlled vehicle sent out to explore. They range in height from small mounds the size of frogs to a large monolith measuring 60 meters (nearly 200 feet) in height. This is the lost city.

Scientists discovered it in 2000. More than 700 meters (2,300 feet) below the surface, The Lost City hydrothermal field is the longest known marine vent environment. Nothing else like it was found.

For at least 120,000 years, and possibly longer, the rising mantle in this part of the world has been interacting with seawater to spew hydrogen, methane, and other dissolved gases into the ocean.

In the cracks and crevices of field openings, hydrocarbons feed new microbial communities even without the presence of oxygen.

Chimneys that emit gases with a temperature of up to 40 ° C (104 degrees Fahrenheit) It is home to an abundance of snails and crustaceans. Large animals such as crabs, shrimp, sea urchins and eels are rare but can still be found.

Despite the harsh nature of the environment, it appears to be teeming with life, and some researchers believe it deserves our attention and protection.

While other hydrothermal fields like this may exist elsewhere in the world’s oceans, this is the only remote-controlled vehicle I’ve been able to find so far.

The hydrocarbons produced by the city’s lost wells were not formed by atmospheric carbon dioxide or sunlight, but by chemical reactions on the deep sea floor.

Since hydrocarbons are the building blocks of life, this leaves open the possibility that life could have originated in such a habitat. And not just on our planet.

“This is an example of an ecosystem that might be currently active on Enceladus or Europa,” microbiologist William Brazelton told the Smithsonian in 2018, referring to the moons of Saturn and Jupiter.

And maybe Mars in the past.”

Unlike volcanic vents dubbed the Underwater Black Smoker, which has also been cited as a possible first habitat, the Lost City’s ecosystem is not dependent on the heat of magma.

Black smokers mainly produce minerals rich in iron and sulfur, while Lost City chimneys produce up to 100 times more hydrogen and methane.

Also, the Lost City’s calcite vents were significantly larger than those of the Black Smokers, suggesting they were active longer.

The tallest monolith is called Poseidon, after the Greek god of the sea, and reaches a height of over 60 meters.

Meanwhile, northeast of the tower is a sloping side with brief bursts of activity. Researchers at the University of Washington describe the openings here as “oozing” liquids to create “clumps of microincrements of polymanic carbon that extend outward like inverted fingers.”

Unfortunately, scientists aren’t the only ones struck by this unusual terrain.

In 2018, it was announced that Poland had gained rights to deep-sea mining around the Lost City. While there are no valuable resources to dredge into the actual thermal field itself, destroying areas around the city can have unintended consequences.

This is the Lost City, a towering ecosystem in the middle of the North Atlantic. It is completely unique as there is no life anywhere else on earth. And if someone wanted to destroy it? There’s nothing you can do about it. No Laws. No consequences. Welcome to the high seas… pic.twitter.com/mdG5wOsr5h

Scientists have warned that any tailings or mine runoff could easily wash away the beautiful habitat.

Therefore, some experts are calling for The Lost City to be declared a World Heritage Site to protect the natural wonder before it’s too late.

For tens of thousands of years, the Lost City has been a testament to eternal life force.

It would be like us to just destroy it.
