Mariana Trench submarine dive finds manmade rubbish at sea's deepest point

Explorer Reaches Bottom of the Mariana Trench Breaks Record for Deepest Dive Ever

Explorer Reaches Bottom of the Mariana Trench Breaks Record for Deepest Dive Ever

The creative director, Anthony Geffen, had this to say, "Our team had to pioneer new camera systems that could be mounted on the submersible, operate at up to 10,000 meters below sea level, and work with robotic landers with camera systems that would allow us to film Victor's submersible on the bottom of the ocean".

Vescovo, a private equity investor who climbed the world's highest peaks before taking on the world's deepest ocean depths, funded the diving expedition into the Mariana Trench himself, according to the BBC. He took the journey with Swiss oceanographer and engineer Jacques Piccard.

Making multiple trips almost 11 km to the ocean floor - one of them four hours in duration - Vescovo set a record for the deepest solo dive in history, his team said.

Victor Vescovo and his submarine "The Limiting Factor" are recovered after completing the deepest dive in history. Each dive takes a total of around 12 hours - about 3.5 hours to descend, 4 hours exploring, and another 3.5 hours to ascend back to the surface.

From behind the glass of a submersible created to withstand extreme pressures, he spent hours observing and documenting the quiet, dark alien world.

"Honestly, it feels like a very great privilege", Vescovo told For The Win Outdoors in an email. "I was surrounded by enormous pressure, but I was safely cocooned in my technological bubble".

"Going to the extremes I believe is a natural inclination of man", said Vescovo to CNN Travel. There have been innumerable cases of sea turtles, fish, seabirds, whales, ducks, tortoise dying after consuming plastic waste. At 26,247 feet (8,000 m), they observed Mariana snailfish and supergiant amphipods (Alicella species) - creatures about 20 times larger than typical amphipods.

Traveling 35,853 feet down, Vescovo and his team also discovered four new species that may help shed light on Earth's murky origins.

Here is a screengrab of the plastic that they found in the deepest trench of the ocean.

It was the voyage to break the record for the world's deepest ocean dive.

Following the expedition, the team now plans to conduct a study to find out if the sea creatures they had collected contain microplastics or not. More worrisome was that Vescovo reported coming across a plastic bag and candy wrappers.

But Vescovo and his team are not stopping now, with another dive of the Horizon Deep within the Tonga Trench in the South Pacific Ocean coming up next.

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