'Lost City' found deep in the Atlantic ocean is like nothing that's ever been seen on Earth

We've all heard of the sunken city of Atlantis, but are you aware of the 'Lost City'?

This particular underwater landscape is yet to have been made into a Disney movie, as it was discovered by accident.

Back in 2000, experts sent rovers to investigate a rocky landscape, and instead, what they found was a potentially 120,000-year-old city.

700 metres below the surface of the Atlantic Ocean was a hydrothermal field, often described as a geological area where hot water circulates beneath the Earth's surface.

It was located west of the Mid-Atlantic Ridge and Science Alert reported that the area is said to be the longest-lived venting environment in the sea.

Scientists now believe that the Lost City could unearth the origin of life, and even possibilities for life on other planets.

Attributes of the underwater area included ancient walls thought to be at least 120,000 years old, with chimneys spewing 104 Fahrenheit gasses and a monolith named after Poseidon, the Greek god of the sea.

Despite the harsh conditions, the 'Lost City' plays host to an abundance of ocean-dwelling creatures, such as snails, microbial communities and various crustaceans.

It’s thought that these beasts feed off the field’s vents, which reportedly spit out hydrogen, methane and other gasses.

Microbiologists also claim that animals such as crabs, shrimps and eels also inhabit the environment.

However, given that there is a distinct lack of oxygen present in the Lost City, these aquatic beats are a rare find.

Scientists say that hydrothermal fields, like the one they found in the Atlantic Ocean, probably exist elsewhere.

Yet the Lost City find remains the only one, which remotely operated vehicles have been able to navigate to thus far.

Speaking about the ancient ecosystem, microbiologist William Brazelton told The Smithsonian in 2018: "This is an example of a type of ecosystem that could be active on Enceladus [Saturn’s moon] or Europa [Jupiter’s moon] right this second and maybe Mars in the past."

Since its discovery, there have been numerous calls to protect the site due to its importance. But in 2018, Poland was given the right to explore 10,000 sq km of the Mid-Atlantic Ridge for mining.

Speaking about the decision, Dr Gretchen Fruh-Green, the scientist who led the discovery said that explorers run the risk of ‘destroying’ the Lost City.

"We could destroy this place before we've understood it - before we can really appreciate the significance of these unique white towers and these very strange fluids that are coming out of the ocean floor,” she told Sky News. “The significance of that for understanding the origin of life, for understanding processes in early Earth.

“It's our history, it's the Earth's history, and if we perturb it we don't know how fast it will recover, or what influence the perturbation would have on ocean chemistry.”
