The ocean occupies two-thirds of the earth's surface, and as humans explore the earth deeply, they have found that there are countless mysterious creatures and landscapes in the depths of the ocean.
While the sheer number and diversity of marine life is staggering, the most unreal thing is that there are lakes like terrestrial lakes in the unfathomable depths of the ocean.
Even these submarine lakes can form ripples and waves, which are shocking.
The famous short film "Around the World in One Breath" shows many amazing scenes, one of which is about a lake in the depths of the sea that raises many questions from the audience.
The audience even thought that it was just a special effects treatment by the short film production team, how could there be a lake in the depths of the ocean?
However, it turns out that submarine lakes are real.
Despair hot tub.
A place called the "Despair Hot Tub" is a prime example of an undersea lake, which is characterized by extremely high water temperatures, high salt concentrations, and many pickled remains of creatures that have fallen into the lake and never escaped.
This place has been dubbed the "Desperate Hot Tub" by marine researchers because the creatures in this lake have apparently died and none of them have survived.
How did the "Despair Hot Tub" come about?
There are a variety of reasons for the formation of submarine lakes, the main of which is the difference in the density of the water.
Salt water is denser than freshwater, so when salt water flows into freshwater, it forms a lake with a lower bottom than the surrounding ocean surface.
This difference in density also causes ripples and waves to sometimes form on the surface of the lake.
However, salt water is not the only reason.
In the lake "Despair Hot Tub", the temperature of the water is also very high, despite the very high salt content.
Researchers believe that this hot and salinity water comes from volcanic activity at the bottom of the sea, where ash and gases ejected from these volcanoes enter the seawater and react with it to form a special solution that is so dense that it can only form lakes on the seabed.
However, the formation of the Despair Hot Tub is not just for this reason, there is another possibility.
The process of ice formation on the seafloor releases large amounts of salt, and when these salts flow into the seawater, they are too dense to combine into solids, forming submarine lakes.
The ecology of the desperate hot tub.
The name "Despair Hot Tub" is apt because the bottom of this lake is a sandy area and the water is full of life.
However, these organisms are all salted by the high salinity and high temperature of the lake's water.
Many creatures unknowingly fall into the lake and end up being salted into dried corpses by the lake's water.
Among them, some unfortunate creatures are digested by bacteria in the lake water, leaving only their shells behind.
The remains of these creatures became part of the unique ecosystem of the Despair Hot Tub, providing nutrients for the bacteria in the lake while also providing valuable samples for researchers.
Biodiversity may have a greater impact on the latter, as we don't know which organisms have fallen into the lake and been salted by high temperatures and high salinity.
The brilliant documentary "Around the World in One Breath" raises many questions, because the ripples that unfold in the lake are not real, but are caused by the impact of the current on the sandy bed.
So, while submarine lakes are real, they don't ripple and wave with currents like lakes on the Earth's surface.
However, submarine lakes remain a puzzling area.
Why does seawater form lakes at the bottom of the underlying region?
This has a lot to do with the formation of submarine lakes.
As mentioned above, the density of seawater is one of the main reasons for the formation of submarine lakes.
The density of seawater varies due to its salt content, and the higher the salt content, the greater the density.
When the density is too high, the seawater sinks to the bottom of the lower area, forming a lake.
The process of mixing seawater also causes a change in the density of seawater, resulting in the formation of submarine lakes.
In addition, the formation of submarine lakes is also related to the action of water currents, which carry seawater to the lower areas and make it form lakes.
Submarine lakes and terrestrial lakes.
There are many similarities between submarine lakes and terrestrial lakes.
First of all, both submarine lakes and terrestrial lakes have water bodies, both of which are made up of water, and the formation of water bodies is due to the surrounding environmental factors.
Secondly, both submarine and terrestrial lakes have bottoms, and both the nature and composition of the bottoms play an important role in the formation and evolution of lakes.
In addition, both submarine and terrestrial lakes have inlet and outflow systems, and the way and speed of inflow and outflow affect the amount of water and water level changes in the lake.
However, there are also many differences between undersea and terrestrial lakes.
First, the environmental conditions of submarine lakes are more complex, with greater depth and pressure, and higher salt content.
Secondly, the mechanisms of water and material cycling are different between submarine lakes and terrestrial lakes.
The movement and circulation of submarine lakes are mainly influenced by ocean flow and bottom topography, while terrestrial lakes are mainly influenced by surface physical and climatic conditions.
In addition, there is a big difference between the biological systems of submarine lakes and those of terrestrial lakes.
Submarine lake ecosystems are made up of microorganisms, bacteria, and other extreme organisms.
These organisms are known as anaerobic organisms and are able to survive in anaerobic or hypoxic environments.
They form a unique ecosystem by growing and reproducing in environments with high salinity, high temperatures, and lack of oxygen.
Unfortunately, due to the high heat and high salinity of the "Desperate Hot Tub" lake, they could not escape from it.
epilogue
Submarine lakes are a realm that feels mysterious and incredible.
Both their formation and ecosystems are areas that scientists have not yet fully understood, and there are still many unsolved mysteries waiting to be explored.
As science and technology continue to evolve, we may discover more about the wonders of undersea lakes and their importance to the Earth's ecosystem.
