The Quran on Deep Seas and Internal Waves

The Quranic account of life in the deep 

seas , the darkness therein, and how it 

confirms modern scientific findings

 

God says in the Quran:" Or ( the situation of non-believers ) is like the darkness in a deep sea . It is covered by waves , above which are 
waves , above which are clouds . Darkness itself . If someone 
extends his hand, he you cannot see .... " (Quran 24:40) Seas

This verse mentions the darkness found in deep water, where if a man stretches out his hand , he cannot see . The darkness in deep seas is around a depth of 200 meters and below . At this depth , there is almost no light (see figure 1 ) . Below a depth of 1000 meters there is no light at all. [Oceans, Elder and Pernetta, p. 27] Humans are not able to dive more than forty meters without the aid of submarines or special equipment . Human beings cannot survive unaided in the dark part of the oceans , such as at a depth of 200 meters. Quran

This verse mentions the darkness found in deep water, where if a man stretches out his hand , he cannot see . The darkness in deep seas is around a depth of 200 meters and below . At this depth , there is almost no light (see figure 1) . Below a depth of 1000 meters there is no light at all. [1 ] Humans are not able to dive more than forty meters without the aid of submarines or special equipment . Human beings cannot survive unaided in the dark part of the oceans , such as at a depth of 200 meters.
 
Figure 1: Between 3 and 30 percent of the sunlight reflected on the surface of the sea. Then, almost all of the seven colors of the spectrum are absorbed one after another in the first 200 meters, except the blue light . (Oceans , brother and Pernetta , p. 27).
 
Scientists have recently discovered this darkness by equipment and submarines that have enabled them to dive into the depths of the oceans special .
We can also understand the following sentences in the previous verse , " ... in a deep sea . It is covered by waves , above which are waves , above which are clouds .... " the deep waters of the seas and oceans are covered by waves, and above these waves are other waves . It is clear that the second set of waves are the surface waves that we see , because the verse mentions that above the second waves there are clouds . But what about the first waves ? Scientists have recently discovered that there are internal waves which " occur on density interfaces between layers of different densities. " [Oceanography, Gross, p. 205] ( see Figure 2) .

Figure 2: The internal waves at the interface between the two layers of water of different densities . One is dense ( the bottom ) and the other one is less dense ( upper ) . ( . Oceanography , Gross, p 204. )

The internal waves cover the deep waters of seas and oceans because the deep waters have a higher density of water above them . Internal waves act like surface waves . They can also break as surface waves . Internal waves cannot be seen by the human eye but can be detected by studying temperature or salinity in a given location. [Oceanography, Gross, p. 205]
