A Texas businessman and deep-sea explorer descended 35,853 feet into the depths of the Pacific Ocean to shatter the record for the world’s deepest dive—and he found plastic trash.
“We feel like we have just created, validated, and opened a powerful door to discover and visit any place, any time, in the ocean—which is 90 percent unexplored,” Vescovo said on April 28 after completing his dive down into Challenger Deep, the world’s deepest spot at the southern end of the Mariana Trench.
Vescovo’s solo dive was punctuated by 248 minutes spent on the bottom exploring the basin, which the expedition team said “is now the longest period of time ever spent on the bottom of the ocean by an individual.”
His double record-setting dive was part of a mission to explore the uncharted depths of the world’s oceans, collect scientific samples, and look for new species.
New Species and Plastic Waste
But aside from investigating exotic geological formations and finding “at least three new species of marine animal,” Vescovo also found examples of ever-pervasive human waste.Sir David Attenborough, a naturalist and wildlife campaigner, reacted to Vescovo’s unsavory find at the bottom of the Mariana Trench by calling plastic in the sea an “unfolding catastrophe” that we “ignore at our peril.”
Four Corners of the Earth
With his dives, Vescovo became the first person to have been to the summit of Mount Everest, been to the deepest recessPatrick Lahey, President of Triton Submarineses of the ocean, and skied to both the North and South poles.Vescovo dove in a submersible called the Limiting Factor, currently the world’s deepest-diving operational submarine.
“Our goal was to build a submersible capable of repeated dives to any depth with its pedigree and security assured by third-party accreditation,” said Patrick Lahey, President of Triton Submarines.
Lahey said the Limiting Factor “represents a quantum leap in the capabilities of a manned submersible and everyone at Triton is immensely proud to have had the privilege and opportunity to create such a remarkable craft, which was only possible by the unwavering support and vision of Victor Vescovo.”
Vescovo’s dive was one of five made by the team between April 28 and May 5, which included the deepest marine salvage operation ever attempted. On May 3, the Limiting Factor submersible freed and recovered a Five Deeps Expedition scientific lander that had got stuck at the bottom of Challenger Deep in a previous dive.
“It has been a monumental week for ocean exploration; we have broken world records and achieved a number of world firsts. Most importantly we have opened the door to the final frontier—the exploration of the hadal zone and the workings of the deepest parts of the world’s oceans,” said Rob McCallum of EYOS Expeditions, whose company is managing the expedition.
“This vehicle is effectively a reliable elevator that can transport us to any depth, in any ocean. During this expedition we have traversed over 110 vertical kilometers (68 miles) and proved the capabilities of a vehicle that will be a platform for science, film making, and exploration of Earth’s hidden recesses,” McCallum added.
Prior to Vescovo’s monumental dive, only two people had successfully made it to the bottom of Challenger Deep.
“Nearly six decades ago Jacques Piccard and I were the first persons to dive into Challenger Deep, the deepest place in the World Ocean,” said oceanographer Don Walsh, who descended into the Mariana Trench in the 1960s.
“Then in 2012, James Cameron made a solo dive there. 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.”
The expedition team notes in the press release that the next stop on the Five Deeps Expedition is the Horizon Deep in the South Pacific Ocean. It is located in the Tonga Trench, considered to be the second-deepest ocean trench in the world.
