Plastic waste has been discovered on a record-breaking dive to the depths of the Pacific Ocean's Mariana Trench.

Victor Vescovo spent four hours exploring the bottom of the trench with the risk of his submersible imploding if anything were to go wrong.

On April 28, in the middle of the Pacific Ocean, Victor Vescovo climbed into the cramped cockpit of his personal $48 million submersible and descended beneath the waves deeper than any human being had been.

Vescovo made multiple trips through the trench.

The team claims to have discovered four new species of prawn-like crustaceans called amphipods, observed a creature called a spoon worm more than 22,000 feet down and a pink snailfish at more than 26,000 feet down, BBC reported.


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.

The team also reportedly found a plastic bag and several candy wrappers.

Mr Vescovo's latest dive is part of the "Five Deeps expedition", where he is attempting to explore the deepest parts of all five oceans. Its next stop will be the Horizon Deep in the South Pacific Ocean's Tonga Trench, which measures at just under 11,000 meters deep to stack in as the second-deepest ocean trench in the world. Movie director James Cameron made the descent in 2012 but failed to beat out the record.

His voyage, in a submersible named The Limiting Factor, is part of a landmark odyssey into the world's watery depths that's being filmed for Discovery Channel - dubbed the Five Deeps Expedition.

The dive to the ocean's deepest point turned up some surprises.

"And now in 2019, the Five Deeps Expedition's submersible Limiting Factor was the third", Walsh said, adding, "And I was there to see it". Atlantic Productions for Discovery Channel/Reeve Jolliffe/Handout via REUTERS.

Diving isn't Vescovo's only passion- he's also a climber.

The expedition's mission is to conduct detailed, sonar mapping missions at the five deepest spots in our oceans. There is also growing evidence that they are carbon sinks, playing a role in regulating the Earth's chemistry and climate.
