The Mariana Trench
Deepest Part of the World
If you turned Mount Everest upside down, then went another mile deep, you'd be as deep as the Mariana Trench. It is not only the deepest part in the ocean, but the deepest part of the world! Until March 26th, 2012, when James Cameron made it to the deepest spot in the ocean, it had only been explored once by humans, more than 50 years before. In 1960 Jacques Piccard and Don Walsh went there in a fishing boat converted into a sea lab. The bathyscaphe, or "deep ship" (aka a free-diving self-propelled deep-sea submersible) was named Trieste. It was named after the city in which it was built, on the border between Italy and Yugoslavia.
While the voyage was a great success, Piccard and Walsh's journey was never repeated until recently. For more than half a century, they remained the only humans to venture into these deep and dark waters. The environment was too toxic to risk further exploration until safer and more sophisticated equipment could be created. Unmanned journeys since theirs managed to shed more "light" on this dark and deep mysterious space. Now with Cameron's Deepsea Challenger vessel, man has gone there again.
See more on Cameron's plunge to the Mariana Trench in the videos below. His dedication to the sea and exploration is quite admirable!

First to explore the Deep
The Ocean's deep was first mapped by the British Challenger expedition, led by Sir Wyville Thomson from 1872-1876. The Challenger circumnavigated the globe and became the basis for Modern oceanography. The team discovered hundreds of new species and mapped underwater mountain chains, which included the Mariana Trench.
The deepest part of the Mariana Trench, which is also the deepest part of the world, was named after this expedition: The Challenger Deep.
Mariana Trench - A Long way down!
The Mariana Trench is 6033.5 Fathoms deep
Sailors used to throw a line into the water, wait until it hit the bottom & pull it back up while measuring the length of the line from finger tip to finger tip. The arm span of an average sailor was 6 feet and called a fathom.

Includes footages of the Marianas Trench where deep mid-ocean ridges regularly erupt and spew hot water and poisonous gasses into the water while sea life inexplicably flourishes on the underwater chimneys.
Deep Blue is a compelling BBC documentary that introduces viewers to some of earth's most mysterious ocean creatures.
The Trieste - Walsh and Piccard ready to load
Just before her record dive to the bottom of the Marianas Trench, 23 January 1960. The dive, to a depth of 35,800 feet in the Challenger Deep, off Guam, was made with Lieutenant Don Walsh, USN, and Swiss scientist Jacques Piccard on board. Waves were about five to six feet high when the two men boarded Trieste from the rubber raft seen at left.

"We think that much of the water that goes down at the Mariana trench actually comes back out of the earth into the atmosphere as water vapor when the volcanos erupt hundreds of miles away,"

Beautiful Life in the Mariana Trench
For in dreams, we enter a world that is entirely our own. Let him swim in the deepest ocean or glide over the highest cloud.

News from around the web - Exploring the Mariana Trench
New expeditions, new forms of life found, all extraordinary ~
As more incredible teams race to be the next on the bottom, we'll follow their progress here. Could you go down that far in the ocean if given the chance? I don't think I could. I would love to be up top watching a live feed though! It would take someone with a lot more guts than me to do explore the unknown depths of the sea! Hats off to James Cameron!

Alamagan Island - Closest Land to the Mariana Trench
A Volcanic Highpoint in the underwater mountain range where the Mariana Trench lies, Alamagan Island is slowly moving closer to the trench, where two techtonic plates converge. Someday, the island may be swallowed up by the sea.
Could we be doing damage to these delicate parts of our planet by contributing to climate change? It is hard to tell. Let us try to preserve these places while we still can! Share your knowledge and spread caring about maintaining the fragile ecosystems of the ocean.
