James Cameron's Deepsea Challenger Now at Ocean's Deepest Point

Cameron Dive First Attempt in Over 50 Years

The Videos Below are suppose to be 3 different one's. The first one, should be the same as the one above from YouTube. I added it, after noticing a problem. It was my favorite and I wanted to make sure and share it. They worked perfectly on my first Page Load. But, after watching them and Reloading the Page. They were showing all the same Video. Must be some weird Auto Changing Code, that they Provided. I'm leaving them as they are. Just in case they work for everyone else. If they don't. You can use the links in the Video Headings to get to the other Video's on their Pages...

As of 5:52 p.m. ET Sunday (7:52 a.m. Monday, local time), James Cameron has arrived at the Mariana Trench's Challenger Deep, members of the National Geographic expedition have confirmed.

His depth on arrival: 35,756 feet (10,898 meters)—a figure unattainable anywhere else in the ocean.
Reaching bottom, the National Geographic explorer and filmmaker typed out welcome words for the cheering support crew waiting at the surface: "All systems OK."
Folded into a sub cockpit as cramped as any Apollo capsule, the National Geographic explorer and filmmaker is now investigating a seascape more alien to humans than the moon. Cameron is only the third person to reach this Pacific Ocean valley southwest of Guam (map)—and the only one to do so solo.
Hovering in what he's called a vertical torpedo, Cameron is likely collecting data, specimens, and imagery unthinkable in 1960, when the only other explorers to reach Challenger Deep returned after seeing little more than the silt stirred up by their bathyscaphe.
After as long as six hours in the trench, Cameron—best known for creating fictional worlds on film (Avatar, Titanic, The Abyss)—is to jettison steel weights attached to the sub and shoot back to the surface. (See pictures of Cameron's sub.)
Meanwhile, the expedition's scientific support team awaits his return aboard the research ships Mermaid Sapphire and Barakuda, 7 miles (11 kilometers) up. (Video: how sound revealed that Challenger Deep is the deepest spot in the ocean.)
"We're now a band of brothers and sisters that have been through this for a while," marine biologist Doug Bartlett told National Geographic News from the ship before the dive.
"People have worked for months or years in a very intensive way to get to this point," said Bartlett, chief scientist for the DEEPSEA CHALLENGE program, a partnership with the National Geographic Society and Rolex. (The Society owns National Geographic News.)
"I think people are ready," added Bartlett, of the Scripps Institution of Oceanography in San Diego, California. "They want to get there, and they want to see this happen."

Rendezvous at Challenger Deep
Upon touchdown at Challenger Deep, Cameron's first target is a phone booth-like unmanned "lander" dropped into the trench hours before his dive.
Using sonar, "I'm going to attempt to rendezvous with that vehicle so I can observe animals that are attracted to the chemical signature of its bait," Cameron told National Geographic News before the dive.
He'll later follow a route designed to take him through as many environments as possible, surveying not only the sediment-covered seafloor but also cliffs of interest to expedition geologists.
"I'll be doing a bit of a longitudinal transect along the trench axis for a while, and then I'll turn 90 degrees and I'll go north and work myself up the wall," said Cameron, also a National Geographic Society explorer-in-residence. (Listen: James Cameron on becoming a National Geographic explorer.)
Though battery power and vast distances limit his contact with his science team to text messaging and sporadic voice communication, Cameron seemed confident in his mission Friday. "I'm pretty well briefed on what I'll see," he said.

Bullet to the Deep
To get to this point, Cameron and his crew have spent seven years reimagining what a submersible can be. The result is the 24-foot-tall (7-meter-tall) DEEPSEA CHALLENGER.

Engineered to sink upright and spinning, like a bullet fired straight into the Mariana Trench, the sub can descend about 500 feet (150 meters) a minute—"amazingly fast," in the words of Robert Stern, a marine geologist at the University of Texas at Dallas.
Pre-expedition estimates put the Challenger Deep descent at about 90 minutes. (Animation: Cameron's Mariana Trench dive compressed into one minute.)
By contrast, some current remotely operated vehicles, or ROVs, descend at about 40 meters (130 feet) a minute, added Stern, who isn't part of the expedition.
Andy Bowen, project manager and principal developer of the Nereus, an ROV that explored Challenger Deep in 2009, called the DEEPSEA CHALLENGER "an extremely elegant solution to the challenge of diving a human-occupied submersible to such extreme depths."
"It's been engineered to be very effective at getting from the surface to the seafloor in as quick a time as possible," said Bowen, of Woods Hole Oceanographic Institution, who also isn't part of the current expedition.
And that's just the idea, the DEEPSEA CHALLENGE team says: The faster Cameron gets there, the more time for science. (Read more about DEEPSEA CHALLENGE science.)
Pursuing speed and science in tandem makes the DEEPSEA CHALLENGER test dives—and even the Mariana Trench mission—perhaps as unorthodox as the sub itself.
Typically "you conduct a sea trial for a vehicle, you pronounce it fit for service, and then you develop a science program around it," Cameron said before heading to the trench. "We collapsed that together into one expedition, because [we were] fairly confident the vehicle would work—and it is."

The bathyscaphe can descend farther and faster into the ocean than its predecessor, the bathysphere. The bathysphere’s cabin was suspended from a cable and could not move with as much freedom as the self-propelled bathyscaphe. This makes the bathyscaphe an important innovation in oceanic exploration.

Swiss scientist Auguste Piccard designed the bathyscaphe, deriving the name from the Greek words bathys ("deep") and skaphos ("ship").

Piccard’s most successful bathyscaphe, the Trieste, was launched in 1953 and dived to 3,150 meters (10,300 feet). In 1958, the United States Navy purchased the Trieste and designed a new cabin that would enable it to reach the floor of ocean trenches. Equipped with this new cabin, the Trieste reached the deepest known point on Earth, the Challenger Deep in the Mariana Trench, on January 23, 1960. Located 10,915 meters (35,810 feet) below the ocean’s surface, the Challenger Deep is deeper than the height of Mount Everest!

An amazing feat of oceanic navigation, the Trieste expedition remains the only manned dive to ever reach the Challenger Deep. Two other unmanned vehicles reached the Challenger Deep in 1995 and 2009, more than 40 years after the Trieste’s descent. The Trieste is now housed at the U.S. Navy Museum in Washington, D.C.

The Bathyscaph (Trieste) Dive to the Bottom of the Sea, 1960.

Go there...

That is something I would love to do! But, there's no way I could go that long without stepping out to take a leak!:O Yes, I think that I would Spring a Leak, long before the Challenger ever would!;)
