The Quran on Seas and Rivers
|
| [size=16]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.1 For
example, Mediterranean sea water is warm, saline, and less dense,
compared to
Atlantic ocean water. When Mediterranean sea water enters the Atlantic
over the
Gibraltar sill, it moves several hundred kilometers into the Atlantic at
a depth
of about 1000 meters with its own warm, saline, and less dense
characteristics.
The Mediterranean water stabilizes at this depth2
(see figure 13).

currents,
and tides in these seas, they do not mix or transgress this barrier.
The Holy Quran mentioned that there is a
barrier
between two seas that meet and that they do not transgress. God has
said:
 He has set free the two seas meeting
together. There is a barrier between them. They do not transgress. 
(Quran, 55:19-20)
But when the Quran speaks about the
divider
between fresh and salt water, it mentions the existence of “a forbidding
partition” with the barrier. God has said in the Quran:
He is the one who has set free the two
kinds of water, one sweet and palatable, and the other salty and
bitter. And He
has made between them a barrier and a forbidding partition.
(Quran, 25:53)
One may ask, why did the Quran mention the
partition when speaking about the divider between fresh and salt water,
but did
not mention it when speaking about the divider between the two seas?
Modern science has discovered that in
estuaries,
where fresh (sweet) and salt water meet, the situation is somewhat
different
from what is found in places where two seas meet. It has been
discovered that
what distinguishes fresh water from salt water in estuaries is a
“pycnocline
zone with a marked density discontinuity separating the two layers.”3
This partition (zone of separation) has a different salinity from
the fresh water and from the salt water4
(see
figure 14).

section
showing salinity (parts per thousand ‰) in an estuary. We can see
here the partition (zone of separation) between the fresh and the
salt
water. (Introductory Oceanography, Thurman, p. 301, with a

recently, using advanced equipment to measure temperature, salinity,
density,
oxygen dissolubility, etc. The human eye cannot see the difference
between the
two seas that meet, rather the two seas appear to us as one homogeneous
sea.
Likewise, the human eye cannot see the division of water in estuaries
into the
three kinds: fresh water, salt water, and the partition (zone of
separation).
