The Quran on Deep Seas and Internal Waves
|
God has said in the Quran:
|
 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. Darknesses, one
above
another. If a man stretches out his hand, he cannot see it.... 
(Quran, 24:40)
This verse mentions the darkness found in
deep seas and oceans, where if a man
stretches out his hand, he cannot see it. 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 (see figure 15). Below a depth of 1000 meters there is no
light at
all.1 Human beings are not
able to dive more than forty meters without the aid of submarines or
special
equipment. Human beings cannot survive unaided in the deep dark part of
the
oceans, such as at a depth of 200 meters.
| Figure 15: Between 3 and 30
percent
of the sunlight is reflected at the sea surface. Then almost all
of
the seven colors of the light spectrum are absorbed one after
another in
the first 200 meters, except the blue light. (Oceans, Elder
and
Pernetta, p. 27.)
|
Scientists have recently discovered this
darkness by means of special equipment
and submarines that have enabled them to dive into the depths of the
oceans.
We can also understand from the following
sentences in the previous verse,
“...in a deep sea. It is covered by waves, above which are waves, above
which are clouds....”, that 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?
Scientists have recently discovered that there are internal waves which
“occur on density interfaces between layers of different
densities.”2
(see figure 16).
| Figure 16: Internal waves at
interface between two layers owater of different densities. One
is
dense (the lowef r one), the other one is less dense (the upper
one). (Oceanography,
Gross, p. 204.)
|
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.3
