A brine pool, sometimes called an underwater, a deepwater lake, or a brine lake, is a volume of brine collected in a seafloor depression. The pools are dense bodies of water that have a salinity that is three to eight times greater than the surrounding ocean. Brine pools are commonly found below polar sea ice and in the deep ocean.
What is the brine lake at the bottom of the sea?
Video of the brine lake at the bottom of the sea. (Quicktime, 1.36 Mb.) As we descended from the south flank of the AC 601 mound, diving down into the central crater, an amazing scene slowly revealed itself below. There at the bottom of this crater on the ocean floor, at a depth of about 2,330 m (7,644 ft) was a “lake.”
Can you live in an underwater brine lake?
Undersea Brine Lake. Due to lethal levels of hyper-salinity, only bacteria and other microorganisms are able to live within these underwater lakes. Mollusks and crustaceans are indigenous to their shores, though crabs and urchins placed in the pool during scientific testing were, effectively, pickled.
Why is a brine pool called a lake?
Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool.
Where are brine pools found?
Aside from the Gulf of Mexico, brine pools are also found in the Red Sea and the Mediterranean Sea. A brine pool is surrounded by a bed of mussels living with methane-consuming bacteria in the sediment. Photo credit: NautilusLive

Can anything live in a brine lake?
Although bacteria and archaea that can breathe methane – often present in abundance in brine -- can live in it, large animals cannot survive. They will become fish pickles if they somehow “fall” in.
Can you swim in brine?
Brine pools are generally toxic to marine animals. When fish and other animals wander into them, they can go into toxic shock or die. Many of the pools contain almost no oxygen and are far too saline for animals to survive.
How far down are brine pools?
These are thought to arise from dissolving pockets of minerals deposited during the Miocene epoch (about 23 million to 5.3 million years ago) when the sea level in the region was lower than it is today. Until now, all known deep-sea brine pools in the Red Sea were located at least 15.5 miles (25 km) offshore.
How salty are brine lakes?
The brine water is about four times as salty as seawater so the ROV Hercules will be able to “float” on the brine while we collect mussel samples from the inner edge. The brine water is saturated with methane slowly bubbling up from subsurface deposits deep under the pool.
What happens if a human goes into a brine pool?
Due to the methods of their formation and lack of mixing, brine pools are anoxic and deadly to most organisms. When an organism enters a brine pool, they attempt to "breathe" the environment and experience cerebral hypoxia due to the lack of oxygen and toxic shock from the hyper-salinity.
What animals can survive in the brine pool?
The brine itself is quite toxic and kills many different fish and other creatures, who happen to stray too far inside or stay too long. In fact, the only organisms that can withstand such noxious conditions are bacteria, tube worms and shrimp.
Is there a lake inside the ocean?
Scientists Have Found a Lake Under The Sea – Those Who Swim There Won't Come Back Alive. Scientists have discovered a 'lake' in the Gulf of Mexico. Everyone, who enters this pool at the bottom of the sea will suffer horribly.
Are brine pools Hot?
A larger brine pool was dubbed the “Hot Tub of Despair,” referring to its warm temperature (19°C) and high salt content—which can be fatal to many animals unlucky enough to fall in.
Is the Dead Sea a brine pool?
It evaporates the water and harvests the salts, including potash for agriculture. The southern section of the Dead Sea today consists entirely of artificial brine pools.
Is there a lake in the bottom of the ocean?
But did you know that in certain places on the seafloor, like in the Gulf of Mexico, there are even underwater lakes and rivers? How is that possible? Well, these lakes and rivers form when seawater seeps up through thick layers of salt, which are present beneath the seafloor.
What liquid is found under the Gulf of Mexico?
The underwater lake, discovered 3,300 feet below the surface of the Gulf of Mexico, is a pit of super-salty water and dissolved methane that kills any critter unlucky enough to fall inside.
Does anything live in salt pools?
These organisms are called “extremophiles.” Some extremophiles are able to thrive in water with salt concentrations six times higher than the oceans. Others can survive in conditions where water is scarcely available at all.
What happens if you swim in salt water?
Saltwater improves and increases your blood circulation by restoring minerals depleted by stress or poor diet. By swimming in cold saltwater you create a stressor in your body that helps boosts your immune system.
Is it safe to swim in pool with low salt?
Answer: The recommended range for salinity level in a saltwater pool is between 25,000 ppm and 35,000 ppm on the higher side. Yes, it's safe to safe to swim since 25k ppm salinity level is still within the recommended range and on the lowest side, unless it reads above 35,000 ppm.
How long after putting salt in pool can I swim?
20 to 45 minutesAfter adding pool salt to your swimming pool, it is always recommended to wait for at least 20 to 45 minutes so that you can swim in the pool.
What is brine water?
Brine, or produced water, is a byproduct of oil and gas production. It consists of water from the geologic formation, injection water, oil and salts. Brine has a high salt concentration the ions of the salts negatively affect the site's soil and vegetation, impairing its ability to produce crops and forage.
What is the brine of a lake?
The brine was probably derived from solution of a shallow salt body at the core of the overall mound. The lake shoreline had familiar features like a high-water mark, a wave run-up zone, and a former higher lake level shoreline. These are features commonly associated with regular sandy coasts. However, when we got closer to the lake it became apparent that the shoreline was defined by clots of white material.

What is the energy in brine?
The brine often contains high concentrations of hydrogen sulfide and methane, which provide energy to chemosynthetic organisms that live near the pool. These creatures are often extremophiles and symbionts.
Why are microorganisms important in brine pools?
A third idea involves using microorganisms in deep-sea brine pools to form natural product drugs. These microorganisms are important sources of bioactive molecules against various diseases due to the extreme environment they inhabit, giving potential to an increasing number of drugs in clinical trials.
How are brine pools created?
Brine pools are created through three primary methods: brine rejection below sea ice, dissolution of salts into bottom water through salt-tectonics, and geothermal heating of brine at tectonic boundaries and hot spots . When sea water freezes, salts do not fit into the crystalline structure of ice so the salts are expelled.
How long does it take for brine to become anoxic?
In the absence of mixing, the brine will become anoxic in a matter of weeks. Salt tectonics.
Why are brine pools toxic?
Due to the methods of their formation and lack of mixing, brine pools are anoxic and deadly to most organisms. When an organism enters a brine pool, they attempt to "breathe" the environment and experience cerebral hypoxia due to the lack of oxygen and toxic shock from the hyper-salinity.
Why is salt needed in brine pools?
For deep-sea brine pools, salt is necessary to increase the salinity gradient. The salt can come from one of two processes: the dissolution of large salt deposits through salt tectonics or geothermally heated brine issued from tectonic spreading centers.

Where are brine pools found?
These saline lakes of dense water on the seafloor has distinctive shorelines and surfaces, and they are called brine pools. They are common in the Gulf of Mexico, where the smallest ones are not much bigger than a puddle, measuring just one meter across, but the biggest pools are up to 20 km long.
What is the name of the saline lake on the seafloor?

How do brine pools affect the ocean?
Brine pools are many times saltier, denser and heavier than the surrounding water. They puddle on the ocean floor with a visible boundary , called a halocline , at the interface between the seawater and the brine pools. These lakes within oceans produce the same effect we see in above ground lakes. For instance, ripples on the lake surface caused by movement of seawater, just like wind causes ripples on the surface of water bodies. The brine is so dense that fish and other marine animals can float on its surface, just like people can float on Jordan’s Dead Sea. When researchers sent submarines to investigate a brine pool, they found the submarines could actually “land” on its surface. It’s only by the use of thrusters they can penetrate the pools.
How deep is the salt bed?
As a result, it grew increasingly salty and when it finally evaporated, it left behind a staggering amount of salt across the former seabed in a thick layer up to 8 km deep. These salt beds still exist under the Gulf and the southern United States as far north as Arkansas.
Is brine toxic to fish?
While mussels thrive along the pool's edge, the brine itself is toxic to most sea creatures. The lakes contain almost no oxygen and is far too saline for animals to survive. Some brine pools also contain toxic chemicals, such as hydrogen sulfide, aside from methane, that kill any fish and sea creature that come into contact with it, earning them various nicknames such as “Jacuzzi of despair” and “pit of despair” and “hot tub of despair”.

Characteristics
Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater creating a distinct interface between water masses. The pools range in area from less than 1 square metre (11 sq ft) to as large as the 120 square kilometres (46 sq mi) Orca Basin. The high salinity raises the density of the brine, which creates a surface and shoreline for the pool. Depending on concentration, some minerals such as baryte (barium sulfate) precipit…
Formation
Brine pools are created through three primary methods: brine rejection below sea ice, dissolution of salts into bottom water through salt-tectonics, and geothermal heating of brine at tectonic boundaries and hot spots.
1. Brine rejection
2. Salt tectonics
Support of life
Due to the methods of their formation and lack of mixing, brine pools are anoxic and deadly to most organisms. When an organism enters a brine pool, they attempt to "breathe" the environment and experience cerebral hypoxia due to the lack of oxygen and toxic shock from the hyper-salinity. If organisms cannot surface long enough to retreat to the rim, they quickly die. When observed by submarines or Remotely Operated Vehicles (ROV), brine pools are found to be eerily littered with …
Microbial diversity and community composition
Metagenomic analysis is a powerful approach for characterizing microbial communities in a variety of environments. Previously, genetic analysis required having the microorganisms in culture, which is problematic since most microorganisms in nature have not been cultivated. Metagenomics overcomes these problems by allowing researchers to directly sample and analyze and ge…

Future uses
One major idea involves harnessing the salinity of brine pools to use as a power source. This would be done using an osmotic engine which draws the high salinity top water through the engine and pushes it down due to osmotic pressure. This would cause the brackish stream (which is less dense and has a lighter salinity) to be propelled away from the engine via buoyancy. The energy created by this exchange can be harnessed using a turbine to create a power output.
