The Abyss: Deepest Part of the Oceans No Longer Hidden
News story originally written on June 2, 2009
A new robot called Nereus has dived deeper than any submarine before to the Mariana Trench, the deepest part of the ocean and where two of the Earth's tectonic plates intersect. The depth Nereus reached is the same distance as the height at which an airplane flies.
Nereus is connected to a ship that floats above by a very small cord, about the thickness of a human hair. Through that cord, the cameras on Nereus can send videos of the ocean floor to the scientists on the ship. The robot is controlled by people on the ship.
Before Nereus, submarines could only dive half the distance. Now, with Nereus, scientists are able to collect samples from places they could not before. The robot also put a sign in the ocean that was signed by all the people on the ship.
