Trash found littering ocean floor in deepest-ever sub dive

Victor Vescovo set a new deep-diving record with this achievement. The explorer is part of the Five Deeps Expedition, which aims to reach the bottom of every ocean on the planet. "As for the plastic, the team found a man-made object at the bottom of the Mariana Trench that resembles a bag, but it is hard to confirm it".

Sea creatures swim around part of a submersible lander, illuminated by the light of the submarine DSV Limiting Factor on the floor of the Mariana Trench, in a still image from video released by the Discovery Channel. A total of four dives in eight days made it the first submersible to ever visit the bottom of the Challenger Deep a couple of times, capturing videos and conducting efficiency tests in the process.

The final challenge will be to reach the bottom of the Molloy Deep in the Arctic Ocean, which is now scheduled for August 2019.

The last visit to Challenger Deep also set a depth record at 35,787 feet.

Prior to Cameron's dive, the first-ever expedition to Challenger Deep was made by the U.S. Navy in 1960, reaching a depth of 10,912 meters.

As well as four new species that could offer clues about the origins of life on Earth, Vescovo observed a plastic bag and candy wrappers at the deepest point on the planet. Vescovo's recent dive broke the record for the deepest decent into the world's oceans, reaching a depth of 35,849 feet and beating the previous record by 36 feet.

The Tonga Trench was previously measured at 10,882 metres deep and is known as the second-deepest ocean trench in the world after the Marina Trench.

The Mariana trench is deep enough to completely submerge Mount Everest.

In the Java Trench, the deepest point of the Indian Ocean, researchers identified a gelatinous animal - thought to be a stalked ascidean, otherwise known as a sea squirt - which they said does not resemble anything seen before.

"It is nearly indescribable how excited all of us are about achieving what we just did", Vescovo told the BBC. "This submarine and its mother ship, along with its extraordinarily talented expedition team, took marine technology to an unprecedented new level by diving - rapidly and repeatedly - into the deepest, harshest area of the ocean".

For the fourth time, the Five Deeps Expedition has successfully dived to the bottom of one of the world's five oceans.

In the next step, the team said its scientists were going to perform tests on the creatures found to in order to have a clear picture about the percentage of plastics found in them.
