The Mariana Trench is the deepest part of the ocean. So, if you were to drop something over board, how long would it take to reach the seabed? By Robert Matthews.
It's a geological feature so massive, so vast and so imposing that it makes Mount Everest look like a mole hill by comparison. Unlike Everest, though, it's nearly invisible and will be forever unseen by the unaided human eye. It's the Mariana Trench, an underwater gash in Earth's crust that's five times longer than the Grand Canyon and much, much deeper.
He spent four hours at the bottom. Vescovo, who is funding the mission himself, has already completed dives in the Indian, Atlantic, and Southern Oceans. It has a titanium hull that is 3.
At this pressure, the density of water is increased by 4. The trench is not the part of the seafloor closest to the center of the Earth. The islands are part of the island arc that is formed on an over-riding plate, called the Mariana Plate also named for the islandson the western side of the trench. The Mariana Trench is part of the Izu-Bonin-Mariana subduction system that forms the boundary between two tectonic plates.

New York: On the deepest dive ever made by a human inside a submarine, a Texas investor and explorer found something he could have found in the gutter of nearly any street in the world - rubbish. Victor Vescovo, a retired naval officer, said he made the unsettling discovery as he descended nearly 11 kilometres 10, metres to a point in the Pacific Ocean's Mariana Trench that is the deepest place on Earth. Victor Vescovo went to the deepest part of Earth, the bottom of the Mariana Trench.
Explorer and businessman Victor Vescovo descended 35, feet 10, meters into the Pacific Ocean, breaking the record for deepest dive ever. At the very bottom, he found colorful rocky structures, weird critters and the ever-pervasive mark of humankind — plastic. Until now, only two people have successfully made it to the bottom of Challenger Deep, the planet's deepest point at the southern end of the Mariana Trench.
Scientists have confirmed that plastic bags litter the very depths of the Earth's oceans inside the Mariana Trench. The findings highlight a polluted region of the ocean often ignored: the very bottom. Their findings have been published in Marine Policy.

CNN — An American undersea explorer has completed what is claimed to be the deepest manned sea dive ever recorded -- returning to the surface with the depressing news that there appears to be plastic trash down there. Victor Vescovo journeyed 10, meters 35, feet to the bottom of the Challenger Deepthe southern end of the Pacific Ocean's Mariana Trench, as part of a mission to chart the world's deepest underwater places. Making multiple trips nearly 11 kilometers, or seven miles, to the ocean floor -- one of them four hours in duration -- Vescovo set a record for the deepest solo dive in history, his team said.
