5 Levels of Pressure Under the Sea
Netgenz - Science | About 71% of the Earth's surface is covered by water and most of it is the largest ocean or ocean. In the eyes of science, exploring the depths of the ocean is seen as more difficult than sending humans into space. Yes, one of the most harmful things to humans under the sea is the pressure that can damage our organs.
Nach, do you want to know what undersea suppression is like? No need to risk diving under the sea. You just have to watch this article to the end.
Here are 5 Levels of Pressure Under the Sea
1. Pressure in the epipelagic zone
Pressure in the epipelagic zone
Quoted by Oceana, the epipelagic zone is an underwater area at a depth of up to an optimal 200 meters. At a depth of 40 meters, humans can dive and our bodies are seen as still strong enough to reduce the existing pressure. However, above 40 meters., divers generally require special equipment because the pressure is already at the level of the limit of human strength.
Nach, at the deepest point in the epipelagic zone there is an emphasis at 20 atm (atmosphere). Should be understood if 1 atm is representative of 10 meters. deep ocean. It means, if this zone is 200 meters deep, then the pressure is at number 20 and surely this can destroy human organs. In general, the human lungs can only absorb the pressure of 3 to 4 atm without a respirator.
2. Pressure will increase in the mesopelagic zone
Pressure will increase in the mesopelagic zone
Under the epipelagic zone, there is an ocean area called mesopelagic or mesopelagic. A paper published at the University of South Florida says that the underwater pressure in this zone reaches 300-1,500 psi. When converted to atmospheric units, it is obtained from 20 to 100 atm.
For humans, this pressure is enormous and can quickly damage human organs, especially the lungs and heart. The depth itself is about at a span of 200 to 800 meters. For your information, the average submarine in the world is only able to explore the ocean at a depth of 250 to 500 meters.
3. Intense pressure in the bathypelagic depths
Intense pressure in the bathypelagic depths
Great emphasis is placed on the bathypelagic zone, an underwater area with an optimal depth of 4 thousand meters. According to the Weather website, this zone is named midnight because it is the darkest. What's the emphasis down there? The figure reaches 5,800 psi aka 394 atm.
This area is a deadly zone for many living things. However, sperm whales can dive deep into the bathypelagic zone to hunt and find food. The temperature here is around 4 degrees Celsius and one of the sources of light is obtained from the bioluminescence of the animals in this area.
4. 6,000 meters under the sea
6,000 meters under the sea
At a depth of 6 thousand meters, the pressure is also massive and not all organisms can live there. According to Britannica, the zone called the abyssal or deep sea has a pressure of 600 atm. Meanwhile, the temperature reaches 0 to 4 degrees Celsius.
The presence of oxygen in this zone depends on the minimum amount dissolved in the water. This lack of oxygen causes the life of organisms to concentrate on the deep seafloor. Generally, small animals at this depth can survive because of the evolutionary process since ancient times.
5. The greatest underwater pressure is in the hadal zone
The greatest underwater pressure is in the hadal zone
The hadal zone or hadalpelagic is the deepest area in the Earth's oceans. One of them mentioned by the hadal zone is the Mariana Trench as the deepest trench on Earth. Yep, this area has a depth of up to 11,000 meters. Sciencing site writes that the emphasis on this place is around 16,000 psi or 1,088 atm and this is a thousand times greater than the uppermost zone of the ocean.
However, because there is such a massive emphasis, several kinds of species can live there. Some organisms that can survive in the hadal zone are snailfish, amphipods, and cusk eels. The coldest temperatures and the deepest darkness made all the species in this area acclimate to eternal darkness. Apparently, the deeper the ocean zone, the greater the emphasis created.
