• Deep dark sea waters

" Or (the unbelievers’ state) is like the darkness in a deep sea. It is covered by waves, above which are waves, above which are clouds. Darkness, one above another if a man streches out his hand, he can hardly see it! For any to whom God giveth not light, there is no light! "
<Qur'an-Al Noor 24:40>

The darkness in deep seas and oceans is found around a depth of 200 meters and below. At this depth, there is almost no light. Below a depth of 1000 meters there is no light at all. Human beings are not able to dive more than forty meters without the aid of submarines or special equipment.
Almost all of the seven colors of the light spectrum are absorbed one after another in the first 200 meters, except the blue light. (Source : Oceans, Elder and Pernetta)

Thanks to special equipment and submarines, scientists were able to dive into the depths of the oceans,and discover the darkness of the oceans. Some scientists have interpreted the "layer upon layer of darkness" to be the gradual separation of the light spectrum within the ocean, one color at a time until complete darkness is finally achieved. In other words, at one depth, the yellow bandwidth is suppressed and "yellow darkness" is achieved. At another depth, the green bandwidth is suppressed and "green darkness" is achieved, and so forth.

• Waves

Also the deep waters of 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? Actually, scientists have recently discovered that there are internal waves which “occur on density interfaces between layers of different densities”. The internal waves cover the deep waters of seas and oceans because the deep waters have a higher density than the waters above them. Internal waves act like surface waves. They can also break, just like surface waves. Internal waves cannot be seen by the human eye, but they can be detected by studying temperature or salinity changes at a given location.

• A partition of the waters

" It is He who has caused to mix freely the two great bodies of water, this one pleasant-tasting and sweet and this one salty and bitter, and He made between them a barrier and a forbidding ban."
<Qur'an-Furqan 25:53>

" He has let free the two bodies of flowing water meeting together.Between them is a barrier which they do not trangress."
<Qur'an-Al Rahman 55:19-20>

Modern science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity, and density. Although there are large waves, strong currents, and tides in these seas, they do not mix or transgress this barrier.

Occasionally, water becomes very heavy due to its high salinity. An example of this is the Mediterranean Sea. The water flowing outward through the Gibraltar Sill has greater salinity than the adjacent water of the Atlantic Ocean, and because it is heavier, it sinks. This Mediterranean flow can be tracked as a tongue of high salinity water most of the way across the Atlantic Ocean. This means that the incoming flow of sea water from the Mediterranean Sea does not admix or combine with the sea water of the Atlantic Ocean. The incoming flow does not loose its identity after traveling a short distance. Surprisingly, the flow from the Mediterranean Sea keeps on traveling "most of the way across the Atlantic Ocean". Since the area of the Atlantic Ocean is about 31,831,000 square miles, it is a very vast distance covered by this flow. The picture above shows that this high density water is like a protruding "tongue" surrounded by the low Density water.

There are many other scientific statements made in the Qur'an which were only discovered to be scientifically accurate only recently. They range over many fields of science including Anatomy, Chemistry, Astronomy, Geology, Hydrology, and many other disciplines which are only beginning to be addressed by scientists today.
