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.
below a depth of 1,000 meters there is no light at
all (Oceans Elder and Pernetta p.27).
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.
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." (Oceanography, Gross, p. 205).
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.
