No no, don't worry. You don't have to swim in Brian! It's not a swimming pool. That's not what we mean by pool. So what's the point?
Brian's Pool is Brian's Lake across a large area on a sea-bed. Brine is a saturated solution of salt or sodium chloride. Brain pool water is usually 3-6 times thicker than the water around it. So, how is it made? Is it a new method or salt conservation? No. First, it is made naturally. Let's see how the 'pool' is made!
Suppose that in the vicinity of a bay, due to natural causes, the soil gradually rises to the surface; That is, an island was formed around it. So since this bay has lost contact with other reservoirs or oceans, its water will evaporate at some point and we know that not only water but also various minerals, salts, sand etc. are mixed in the sea water - the amount of salt after water is the highest! So a large amount of salt pulp is made by mixing these substances with salt. So if a rupture occurs due to the transfer of tectonic plates to that place due to geo-natural causes - the place where the bay has dried up and only salt has accumulated there - the water flow starts again. But the amount of salt in the salt paste is actually so high that it does not happen that the water started circulating and the salt in the paste dissolved with the water. Moreover, due to the cracks - the sediment that kept the bay ‘isolated’ separates and a layer of sediment falls on the salt - which acts as a barrier to the salt mixing with the water. Then more sediment accumulates with the water and the pressure on the salt continues to increase and this causes the frozen piles of salt to go deeper and deeper into the sea. It is called 'Salt Tectonic'.
As a result of the formation of salt tectonics, it is usually possible to give more in some places and the pile of salt between any two places will give a little height and take the shape of a dome. When the dome comes in contact with the water above the relatively light sedimentary layer above it, the salt begins to drip from there and a local-excess saline-different concentration lake or reservoir is formed there. This reservoir is called 'Brain Pool'.
This salt dome penetrates the top layer of silt and often hits piles of hydrocarbons or accumulated hydrocarbons. As a result, methane bubbles in the thick water and accumulates on the shores of the ‘Brian Pool’. And oysters are commonly found on the shores of the Brain Pool - those that can survive in this condition and have a symbiotic relationship with ‘chemosynthetic’ bacteria. Those bacteria take advantage of methane - turning it into carbon sugar.
However, this water is not common just because of salt water. This water is basically very toxic! It contains harmful chemicals such as hydrogen sulfide methane. Even most deep-water animals usually die when they dive into or enter the pool's water - often this water turns the animal into a pickle! Any animal that enters the pool can eat ‘toxic shock’! Understandably, this water is also harmful to plants. This pool has won several titles - "Jacuzzi of despair", "pit of despair", "hot tub of despair". Usually only ‘extrememophile’ organisms can survive in this water.
So where has Brian Pool been built so far? The Gulf of Mexico, The Red Sea, The Mediterranean Sea
