Oceanic Division according to the Quran

The Quran mention the sea in several verses, including its creation, its role in sustaining life, and its vastness. From a scientific perspective, the ocean can be divided into several zones based on depth and light penetration. These zones include the epipelagic zone (0-200 meters), the mesopelagic zone (200-1000 meters), the bathypelagic zone (1000-4000 meters), the abyssopelagic zone (4000-6000 meters), and the hadalpelagic zone (below 6000 meters). Each of these zones has distinct characteristics, such as temperature, pressure, and light levels, which determine the types of organisms that can survive there.

Also, based on salt density, the ocean can be divided into three main layers or zones: the surface layer, the intermediate layer, and the deep layer.

The surface layer, also known as the mixed layer, extends from the ocean's surface to a depth of about 100 to 200 meters. This layer is mixed by wind and currents, and its salinity is relatively uniform throughout. The intermediate layer, also known as the thermocline, extends from the bottom of the mixed layer to a depth of about 1000 meters. In this layer, the temperature decreases rapidly with depth, while the salinity increases, creating a sharp boundary or thermocline between the mixed layer and the deep layer. The deep layer, also known as the abyssal zone, extends from the bottom of the thermocline to the ocean floor. This layer is characterized by a constant, low temperature and high salinity. The density of the water increases with depth due to the high salt content, and it can also be influenced by factors such as pressure and temperature.

The Quran does mention the sea in several verses, including its creation, its role in sustaining life, and its vastness.

For example, in Surah Al-Rahman (55:19-20), it says: 

"He has let free the two seas, meeting together. Between them is a barrier, which none of them can transgress."

This verse refers to the meeting of the saltwater and freshwater and the separation between them, which is necessary for sustaining life.

Here is a mention of oceanic layers based on salt density in the Quran. It does mention the sea and its properties. 

In Surah Al-Furqan (25:53), it is said: 

"And it is He who has let free the two seas, one palatable and sweet, and the other salty and bitter, and He has set a barrier and a complete partition between them."

This verse refers to the separation between the saltwater and freshwater and how each has its own distinct properties.

While the Quran doesn't specifically mention the "Oceanic Division," it does refer to the sea and its properties, which may be of interest to those studying the ocean and its ecosystems.

Overall, while the term "Oceanic Division" may not have a specific scientific or Quranic definition, the Quran mentions the sea and its properties, and science has classified the ocean into various zones based on depth and light penetration.
