'Lost City' Deep in the Atlantic Like Nothing Else We've Ever Seen on Earth

The reality of what lies within our oceans has fascinated people since time immemorial, so it’s no wonder we’ve created countless myths about the watery depths.

But step aside, Atlantis, scientists have discovered a real Lost City beneath the waves, and this one is teaming with life.

The rocky, towering landscape is located west of the Mid-Atlantic Ridge mountain range, hundreds of meters below the surface of the Atlantic Ocean, and consists of massive walls, columns and monoliths stretching more than 60 meters tall, according to The Independent.

To be clear, it’s not the home of some long-forgotten human civilization, but that doesn’t make its existence any less significant, it said.

The hydrothermal field, dubbed the “Lost City” upon its discovery in the year 2,000, is the longest-lived venting environment known in the ocean, Science Alert reports.

Nothing else like it has ever been found on Earth, and experts think it could offer an insight into ecosystems that could exist elsewhere in the universe.

For more than 120,000 years, snails, crustaceans and microbial communities have fed off the field’s vents, which spout out hydrogen, methane and other dissolved gases into the surrounding water.

Despite the absence of oxygen down there, larger animals also survive in this extreme environment, including crabs, shrimps and eels. Although, they are, admittedly, rare.

The hydrocarbons produced by its vents were not created by sunlight or carbon dioxide, but by chemical reactions way down on the seafloor.

The tallest of the Lost City’s monoliths has been named Poseidon, after the Greek god of the sea, and it measures more than 60 meters high.

Meanwhile, just northeast of the tower, is a cliffside where the vents “weep” with fluid, producing “clusters of delicate, multi-pronged carbonate growths that extend outward like the fingers of upturned hands,” according to researchers at the University of Washington.

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday.
Scientists know that the loss of Antarctic sea ice can diminish penguin numbers, cause ice shelves to melt in warmer waters, and impede the Southern Ocean from absorbing carbon dioxide, AFP reported.
But this new research, published in the peer-reviewed journal Nature, explores another consequence: increased heat loss from the ocean to the atmosphere, and an associated rise in storms.
Since 2016 there has been a large-scale reduction in Antarctic sea ice, but nothing like 2023 when a record amount failed to reform over the winter.
For this study, Simon Josey of the UK's National Oceanography Center and colleagues focused on three regions that experienced unusually high levels of sea-ice retreat that year.
Using satellite imagery, ocean and atmospheric data, and wind and temperature measurements, they found some newly ice-free areas experienced double the heat loss compared to a stabler period before 2015.
This was accompanied by "increases in atmospheric-storm frequency" over previously ice-covered regions, the authors found.
"In the sea-ice-decline regions, the June–July storm frequency has increased by up to 7days per month in 2023 relative to 1990–2015."
The loss of heat caused by reduced sea ice could have implications for how the ocean circulates and the wider climate system, the study added.
Oceans are a crucial climate regulator and carbon sink, storing more than 90 percent of the excess heat trapped near Earth's surface by greenhouse gas emissions.
In particular, sea-ice retreat could mean changes in how a deeper layer of cold, dense Antarctic bottom water absorbs and stores heat.
The authors said further in-depth analysis of possible climate impacts were needed, including if sea-ice retreat could have even further-reaching consequences.
"Repeated low ice-cover conditions in subsequent winters will strengthen these impacts and are also likely to lead to profound changes further afield, including the tropics and the Northern Hemisphere," it said.
