Deep in the waters of the Red Sea, scientists have uncovered an astonishing discovery—hidden natural “death traps” on the seafloor.
These mysterious brine pools, found nearly 4,000 feet below the surface in the Gulf of Aqaba, are some of the most extreme environments on Earth.
The pools are so salty—up to 10 times saltier than normal seawater—that they lack oxygen, effectively suffocating any life that dares to enter.
But what makes these brine pools even more fascinating is their resemblance to early Earth conditions.
Researchers believe these deep-sea environments might mimic the harsh conditions where life first began millions of years ago.
A Window Into Earth’s Past
Brine pools aren’t something you come across every day.
In fact, only around 40 have been discovered in the Red Sea, Mediterranean, and the newly named Gulf of American.
These pools are not just deadly to life forms; they also act as natural archives, preserving historical records about the region.
The undisturbed layers of sediment within these pools allow scientists to explore past geological events, like tsunamis, earthquakes, and flash floods that happened thousands of years ago.
The pools are located in a particularly intriguing area of the Red Sea—the Gulf of Aqaba, which some experts believe may be the very spot where Moses parted the waters while leading the Israelites to the Promised Land.
The researchers, who have dubbed these brine pools the “NEOM Brine Pools,” stated, “They extend the known geographical range of Red Sea brine pools and offer a unique preservation environment for the sedimentary signals of regional climatic and tectonic events.”
Mystical Waters and Unique Geology
The Gulf of Aqaba itself has long been considered a mysterious place due to its unique geological features.
From extreme depths and volcanic activity to unusual temperature variations at different depths, this region is unlike any other.
In fact, its extraordinary geography has led some to speculate that this could be the location described in the Bible during the Israelites’ journey, particularly because the Gulf is deeper and wider than other parts of the Red Sea.
This ancient connection to the Moses story adds another layer of intrigue to an already fascinating region.
The Unexpected Discovery
While exploring these deep waters with a remotely operated underwater vehicle (ROV), a team of scientists from the University of Miami stumbled upon something remarkable.
After six weeks of exploration, Professor Sam Purkis said they were lucky to find the pools in the final moments of a 10-hour dive.
As they descended, the ROV captured images of a desolate seabed covered with thick mud, which led the researchers straight to the brine pools.
Because brine is denser than regular seawater, it stays at the ocean’s bottom, rarely mixing with the surrounding water.
This results in the formation of isolated underwater lakes or ponds where only the toughest organisms can survive.
Life in the Extremes
Although the conditions in these pools would instantly destroy most life forms, scientists found some unexpected residents.
The pools are home to extremophiles—organisms that thrive in extreme conditions.
These include single-celled organisms, like prokaryotes, which can endure high salinity, pressure, acidity, or radiation.
They also discovered sulfate-reducing bacteria, which feed on sulfate and are responsible for dramatically changing the chemical makeup of the brine.
These bacteria have reduced the sulfate levels to the lowest levels ever recorded in the region.
Interestingly, even though life can’t survive in the brine pools themselves, other creatures, such as eels, shrimp, and mollusks, can be found nearby, feeding on the bacteria and creating a unique ecosystem around these harsh environments.
Clues for the Search for Life Elsewhere
The team of scientists believes these brine pools may hold valuable clues about life on other planets.
According to Professor Purkis, “Our current understanding is that life originated on Earth in the deep sea, almost certainly in anoxic—without oxygen—conditions.”
The extreme conditions of these deep-sea brine pools could be a window into what life’s beginnings may have looked like and might even help guide future research on other “water worlds” in our solar system and beyond.
The researchers also gathered core samples from the pools, which provide an unbroken record of past events.
These samples cover over 1,000 years of regional history, revealing important information about major weather events.
According to Purkis, “Major floods occur about once every 25 years, and tsunamis about once every 100 years.”
This data adds a fascinating historical layer to the region’s geological story.
These remarkable discoveries not only reveal the untold mysteries of the Red Sea but also deepen our understanding of how life might have originated—and how it could exist elsewhere in the universe.
