Observe the deepest place in the ocean

Scientists identify the deepest place in the Pacific with a distance of 11,000 meters, and are not easy to study at such depths.

The robot submarine called Nereus (pictured) is entering the final preparation stage before diving into the seabed. If successful, this is the first time an automatic diving device has reached the deepest place in the world. Previously, there were 2 devices dive into this place but all were controlled by people.

Andy Bowen, one of the Nereus designers, said the device will study at depths of 1,000m, 4,000m, 8,000m and eventually 11,000m. The study will start from 23.5 - 6.6. The Challenger Deep - the deepest place in the world - belongs to the Marianas area, near the island of Guam, west of the Pacific Ocean. At a depth of 11,000m, the pressure increased to 1,100 times the surface of the ocean.

In January 1960, Jacques Piccard and Don Walsh made their first trip to record depth with a diving device called Trieste. During the 9-hour journey, the two men had 20 minutes at a depth of 10,916m.

35 years later, a Japanese remote-controlled diving device called Kaiko successfully made a dive down to 10,911m. Unlike Nereus, Kaiko connects with a ship on the sea to receive active energy and is under control.
