- NEW: it felt like another planet, director James Cameron says
- NEW: At a microbial level, life is adapting, Cameron says
- NEW: the hydraulic system did not work, so samples could not be brought back, Cameron says
- He is the first person to dive solo to that spot, the deepest in any of the world’s oceans
(CNN) — Oscar-winning director James Cameron resurfaced Monday after plunging to the deepest known point in the world’s oceans in his one-man submersible.
His history-making solo venture to Challenger Deep, part of the Mariana Trench in the western Pacific Ocean, left him feeling “complete isolation from all of humanity,” he said.
“I felt like I literally in the space of one day have gone to another planet and come back.”
At more than 10,900 meters (about 35,800 feet), the Mariana Trench is deeper than Mount Everest is tall. it has had only two previous human visitors: U.S. Navy Lt. Don Walsh and the late Swiss explorer Jacques Piccard, who descended to that spot in 1960.

Cameron is the first to make the trek alone. And he did so hours before he was due in London for the premiere of the 3-D version of his 1997 blockbuster movie, “Titanic.”

The man who was also behind “Avatar” went down in a high-tech vessel, the Deepsea Challenger, which he and a group of scientists and engineers constructed in Australia over the past eight years.
The bottom was a “very soft, almost gelatinous, flat plane, almost featureless” and went as far as he could see, Cameron said, describing the “vast frontier down there.”
“It’s a completely alien world,” he said.
But he did not see the kind of large life forms that some might dream up, he said.
“We’d all love to think there are giant squid and sea monsters down there. We can’t rule it out, but my bet is there aren’t. what you’re going to find is these very, very interesting animals, the likes of which we’ve never seen before, that have adapted to this extreme environment.”

In a video feed afterward from a large ship, Cameron told reporters, “I had this idea that life would adapt, life would be able to adapt to the deepest place. But I don’t think we’re seeing that. At a microbial level, yes, life is adapting.”
He said he did not see fish at such depth. “The only free swimmers I saw were these little … shrimplike animals,” scavengers that devour potential food that falls, such as dead fish or whales.
It’s a cold, dark, “completely black world that’s devoid of sunlight” and warmth, he said.
Animals that far down are usually white with no pigment, he said. some have eyes to see bioluminescence, while others have no eyes.
The full trip took about seven hours, he said.
While the journey went well, one technical glitch caused a problem, he said. the hydraulics prevented him from using a manipulator arm to collect samples to bring back to the surface. Cameron said he’s confident it will be fixed for the next trip.
This trip is only the beginning, he said.
Horrific tsunamis originate in the depths of the ocean, he said, suggesting that a better understanding could ultimately help societies understand and prepare for such disasters.
And some believe life may have originated in what are now the oceans’ lowest points, he said. so the research could help answer some “fundamental questions.”
In an era in which anyone can use Google maps to zoom in on a satellite image of any part of the world, “the last frontier that really exists” on Earth is the deep ocean, Cameron said.
Cameron reached the point near Guam at 7:52 a.m. Monday (5:52 p.m. ET Sunday), said Ellen Stanley, a spokeswoman for the National Geographic Society, which is working with Cameron on the project.
Outfitted with special cameras and robotic arms, Deepsea Challenger is able to dive vertically at speeds of 500 to 700 feet per minute and can withstand immense pressure — up to 16,000 pounds per square inch.
The descent took 2 hours, 36 minutes.
“Just arrived at the ocean’s deepest pt,” he tweeted at the time. “Hitting bottom never felt so good.”
It wasn’t immediately clear how Cameron managed to update his Twitter feed from such depths. When astronauts sent tweets from space, they were e-mailed to mission control, where support staff posted them to the astronauts’ Twitter accounts. (But that changed in 2010, when the International Space Station received a special software upgrade that NASA called “the ultimate wireless connection.”)
It is estimated that more than 750,000 marine species have not been formally described in scientific literature over the centuries, triple the number of those that have been. the figures exclude microbes; a 2010 marine life census estimates there are up to 1 billion kinds of those.
At noon (10 p.m. ET Sunday), the sub broke through the surface after a quick 70-minute ascent.
Billionaire businessman and adventurer Richard Branson and Patrick Lahey, an experienced submarine pilot, had also sought to make the first solo trip to Challenger Deep.
The nonprofit X-Prize Foundation has announced it will award a $10 million prize to the first person to reach the bottom of the Mariana Trench. Cameron said he’s not interested in competing for this prize, or any other, because his mission is purely about scientific research.
“You know, there’s so much we don’t know,” Cameron recently told CNN. “I’m hopeful that we’ll be able to study the ocean before we destroy it.”

Hollywood icon James Cameron has made it to Earth’s deepest point and back.
The Canadian director of “Titanic,” “Avatar” and other films used a specially designed submarine to dive nearly 11 kilometres, completing his journey a little before 8 a.m. this morning Honolulu time, according to Stephanie Montgomery of the National Geographic Society.
He spent about three hours exploring and filming the Mariana Trench, about 320 kilometres southwest of the Pacific island of Guam before ascending to the surface.
“All systems OK,” were Cameron’s first words upon reaching the bottom, according to a statement. his arrival at a depth of 10,898 metres came early Sunday evening on the U.S. East Coast, after a descent that took more than two hours.
The scale of the trench is hard to grasp — it’s 120 times larger than the Grand Canyon and 1.6 kilometres deeper than Mount Everest is tall.
Cameron made the dive aboard his 12-ton, lime-green sub called “Deepsea Challenger.” He planned to collect samples for biologists and geologists to study.
“It’s really the first time that human eyes have had an opportunity to gaze upon what is a very alien landscape,” said Terry Garcia, the National Geographic Society’s executive V-P for mission programs, via phone from Pitlochry, Scotland.
The first and only time anyone dove to these depths was in 1960. Swiss engineer Jacques Piccard and U.S. navy Capt. Don Walsh took nearly five hours to reach the bottom and stayed just 20 minutes. They had little to report on what they saw, however, because their submarine kicked up so much sand from the ocean floor.
“He is going to be seeing something that none of us have ever seen before. He is going to be opening new worlds to scientists,” Garcia said.
One of the risks of a dive so deep is extreme water pressure. at 10.9 kilometres below the surface, the pressure is the equivalent of three SUVs sitting on your toe.
Cameron told the associated Press in an interview after a 8.2 kilometre-deep practice run near Papua new Guinea earlier this month that the pressure “is in the back of your mind.”
The submarine would implode in an instant if it leaked, he
said. But while he was a little apprehensive beforehand, he wasn’t scared or nervous while underwater.
“When you are actually on the dive you have to trust the engineering was done right,” he said.
The film director has been an oceanography enthusiast since childhood and has made 72 deep-sea submersible dives. Thirty-three of those dives have been to the wreckage of the Titanic, the subject of his 1997 hit film which is being released in a 3-D version next month.
