Diver breaks record for deepest dive

Diver breaks record for deepest dive

Epic trip: The Mariana Trench dive is part of a series of dives known as the Five Deeps Expedition: an attempt to visit the deepest point in each of the world's five oceans. A total of four dives in eight days made it the first submersible to ever visit the bottom of the Challenger Deep a few times, capturing videos and conducting efficiency tests in the process.

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.

Mr Vescovo also saw angular metal or plastic objects, one with writing on it. The team also discovered brightly colored rocks on the sea floor, potentially formed by microbes, the BBC reports. And now in 2019, "The Five Deeps Expedition's submersible Limiting Factor was the third".

"I think nearly exactly 12 hours, [i.e.] four hours on the bottom, which I think is the longest anyone has ever been on the bottom of the Challenger Deep".

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".

"It is very important to us that we show some initial scientific discoveries, just to give a small sample of what we could do if the sub was in the hands of a professional research organization", he says. "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". Titanic director and frequent diver James Cameron set the previous record in 2012.


Victor Vescovo journeyed 35,853 feet to the bottom of the Challenger Deep as part of a mission to chart the world's deepest underwater places, CNN reported.

For the fourth time, the Five Deeps Expedition has successfully dived to the bottom of one of the world's five oceans. The 15-foot-long, 12-foot-high submersible features a 3.5-inch-thick titanium pressure hull that can accommodate two people, and dives can be conducted solo or as a pair.

Scientists plan to test the newly-discovered creatures to see if they contain microplastics.

Technology has changed quite a bit since the Challenger Deep was first explored in 1960 by oceanographers Don Walsh and Jacques Piccard in the submersible Triest.

In the May/June issue of Hydro International we'll publish an article about the Five Deeps Expedition.

The area in the ocean is known as Challenger Deep.
