Bottom of the ocea

Facebook Twitter Email. 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 Deep , the 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. The previous record was held by "Titanic" director James Cameron in

It may seem crazy, but we know more about the surface of Mars than we do about the ground beneath our oceans. Yet beneath the sea is a whole underwater landscape with valleys, mountains and even volcanoes. As a rule, we are more inquisitive about things we often see but do not fully understand, than we are about things we rarely see at all. It is quite easy to forget that there is a world under our oceans, whereas the Moon shining brightly in the sky taunts us into wanting to find out more.

Essentially, no one is certain of the things that lie at the bottom of the sea. The oceans deepest darkest deep depths have proven more challenging to reach than traveling to the moon. In all of human history, 12 people have reached the moon, while only three have reached the bottom of the deepest part of the ocean: the Challenger Deep. The deepest point- located within the Marina Trench, reaches nearly 10, meters deep - beyond the depths which light can reach. The engineers questioned whether the dive would be possible for humans to survive, backed by the most sophisticated engineering of the time- nevermind discovering any life.
