Many years after the Valdivia expedition, Amanda observed something remarkable:
“In 1960, two men, Jacques Piccard and Don Walsh, were
setting off into the deep sea in a kind of capsule. Their
destination was the Mariana Trench.
I prefer to remain
at a depth of about 3,000-4,000 meters. I find a
lot to eat at that depth, and I generally feel best
there. But the two men dove even deeper in their
submarine, all the way down to the bottom
of the Mariana Trench — oh man, that’s
really deep!”
Expeditions such as this one have taught us
quite a bit about the deep sea. But most of it is
still cloaked in mystery.
WHAT IS THE DEEP SEA?
Over half of Earth’s surface is
covered with water. And most of
that is salty sea water.
The deep sea is what we call those
regions of the ocean that have a
depth of 200 meters or greater.
Most of the water in the world’s
oceans is in the deep sea.
The deep sea comprises several
layers. You can see that in the
illustration.
The deepest point measured so far is
in the Mariana Trench, at about
11,000 meters under the ocean
surface.
There are still presumed to be over
one million undiscovered animal
species in the deep sea.
