And that part is the Challenger Deep.

那就是挑战者深渊。

This remote place is called the Challenger Deep.

这个偏远的地方被称为“挑战者深渊”。

Only a couple dozen have reached the seven mile depth of the Challenger Deep, so it's largely unexplored.

但只有几十个达到了7英里深的“挑战者深渊”，所以它在很大程度上还没有被探索过。

So we're talking about a pretty big scar overall and the Challenger Deep is near the southern end of it.

所以可以说是一个很大的伤疤，挑战者深渊就在它的南端。

A special edition, an in depth show because you really can't go anywhere more in depth than the Challenger Deep.

一期特辑，一个深度展示，因为你不可能真的去到比挑战者深渊更深的地方了。

Part of that is the Challenger Deep.

其中一部分是挑战者深渊。

Located in the Mariana Trench, Challenger Deep has been visited by just three people: two oceanographers in 1960 and filmmaker James Cameron in 2012.

挑战者深渊位于马里亚纳海沟，只有三个人参观过：两位海洋学家于 1960 年到过那里，还有导演詹姆斯·卡梅隆在 2012 年到过那里。

In 1960, the first  manned submarine dove to the Challenger Deep, the lowest point in the Mariana Trench.

1960 年，第一艘载人潜艇潜入马里亚纳海沟的最低点挑战者深渊。

The Challenger Deep in the Marianas Trench is the deepest point in the world that we're aware of so far, plunging nearly 11 kilometers beneath the waves.

马里亚纳海沟的挑战者深渊是我们迄今所知的世界上最深的地方，深入水下近 11 公里。

Even though thousands of people have reached the top of the world on Mt. Everest, fewer than 25 have reached the bottom of it in the Challenger Deep.

尽管成千上万的人在珠穆朗玛峰登上了世界之巅，但只有不到25人去到挑战者深渊，潜入了世界之底。

Finally, when we hit 10, 994 meters we have hit the bottom of the known ocean, called the Challenger Deep, right here on this map just about 300 kilometers southwest of Guam Island.

最后，到 10994 米的深处，就是目前已知的海洋最深处了，也叫挑战者深渊，就在地图上这里，在关岛西南方向约 300 千米的海域。

The only other people to plumb the Challenger Deep -as its name suggests, the most profound point in the ocean-were Jacques Piccard and Don Walsh, who did so in 1960, in a vessel called Trieste.

此外只有雅克·皮卡和唐纳德·沃尔什探索过挑战者深渊——正如其名，它是海洋的最深点——他俩于1960年驾驶里雅斯特号深海潜艇下潜至此处。

My expedition was inspired by the great Jacques Piccard and Don Walsh, who in 1960 were the first to reach the deepest point of our oceans, the Challenger Deep, at the bottom of the Mariana Trench.

雅克·皮卡德与当·沃尔什激励我踏上这条探索之路，他们于1960年下潜至马里亚纳海沟底部，成为抵达海洋最深处的先驱。

Also, the development of submersibles that can  survive such pressures are usually very expensive one-off creations, such as the Trieste that  first ventured to the Challenger Deep in 1951.

此外， 能够承受这种压力的潜水器的开发通常都是非常昂贵的一次性发明，例如 1951 年首次进入挑战者深渊的里雅斯特号。

This was in sharp contrast to a less publicised mission, to the paltry depth of 2.5km, where the pressure is a mere 250 times that of the atmosphere (the Challenger Deep's pressure is four times that).

这与一项不太为人所知的行动形成了鲜明对比，后者只下潜到区区2.5千米，承受了250个大气压（挑战者深渊那里的压强四倍于此）。

The Challenger Deep has been dived twice, once in 1960 and once in 2012 by James Cameron, and they went down and came back up and those were experimental craft.

Challenger Deep 潜水过两次， 一次是在 1960 年，一次是在 2012 年， 詹姆斯·卡梅隆 (James Cameron) 下潜了一次， 然后又浮上来， 这些都是实验性的工艺。

While modern submersibles may even be able of reaching the depths of Challenger Deep, none have tried since the famous expedition of the Trieste bathyscaphe- yet today, surprisingly enough its NASA that is interested in very deep-diving submersibles.

虽然现代潜水器甚至可能能够到达挑战者深渊的深处，但自从著名的的里雅斯特深海潜水探险以来，没有人尝试过。然而今天，令人惊讶的是，NASA对深潜潜水器开始感兴趣。

This process, known as subduction, leads to the formation of some of the deepest parts of the ocean, such as the Mariana Trench in the western Pacific, which contains the deepest point on Earth, the Challenger Deep.

这个过程被称为俯冲，导致一些海洋最深处的形成，例如西太平洋的马里亚纳海沟，其中包含地球最深点——挑战者深渊。
