Its surface, new measurements reveal, is as black as the blackest material known-the result of an abyssal arms race.

最新测量数据表明其表面和最黑暗的已知物质一样黑—这是海军备竞赛的结果。

From the atmosphere to the abyssal zone, we are polluted.

从大气层到海区， 我们都被污染了。

The abyssal zone technically are depths between 3,000 and 6,000 meters.

从技术上讲，海区的 3,000 至 6,000 米之。

The abyssal zones account for about 70 percent of the planet.

海区约占地球面积的 70%。

Sea cucumbers are found everywhere from shallow shores to abyssal trenches 6,000 meters below sea level.

从浅滩到海平面以下 6000 米的海海沟，海随处可见。

And not " the abyss" like they say on TV.The abyssal zone technically are depths between 3,000 and 6,000 meters.

而不是他们电视上所说的“渊”。从技术上讲，渊区的 3,000 到 6,000 米之。

The dark, high pressure abyssal reaches of the ocean produce probably the most alien  looking lifeforms out of any found on our world.

黑暗、高压的海区域可能孕育着地球上最外星生命形式。

So these animals are essentially gardening because if they didn't do that, these big, vast abyssal plains of the planet would become big, stagnant, horrible cesspits.

所以这些动物本质上是园艺，因为如果它们不这样做，地球上这些广阔无垠的海平原将变成巨大、停滞、 可怕的污水坑。

But the Mediterranean and  Caribbean Seas are really oceans, in the sense that they fall away to deep  abyssal plains where no light can reach.

但地中海和加勒比海实际上是海洋，因为它们延伸至光线无法到达的海平原。

Any oxygen found in regions where photosynthesis is impossible—such as the abyssal seafloor, a pitch-black realm up to 6,000 metres deep—was thought to be surface gas on the move.

光合作用无法进行的区域中发现的任何氧气——例如达6000米的黑暗海底——曾被认为是移动的表面气体。

This effect is most pronounced in  the tropics, while at the poles, the temperature of seawater is more or less the same from  the surface down into the abyssal depths.

这种效应热带地区最为明显，而两极， 从表面到海， 海水温大致相同。

The depth of the open ocean varies considerably  but the majority of it falls from the continental shelf down to depths of between 3,000 and 6000  meters, in what are known as abyssal plains.

公海的差异很大， 但大部分从大陆架延伸到 3,000 至 6,000 米的地区，即所谓的海平原。

Barron, who has invested millions of dollars in preliminary environmentalimpact assessments, describes the abyssal plain where the nodules are located as a " lifeless desert" where the impact of mining is likely to be minimal, if felt at all.

巴伦初步环境影响评估中投入了数百万美元，他将结核所的海平原描述为一个 “无生命的沙漠”，采矿的影响可能是极其微小的。

The first indications that this gas was being produced on the abyssal seafloor came in 2013, when researchers noticed that oxygen levels were higher near polymetallic nodules, lumpy agglomerations of metal and minerals found across the ocean floor.

2013年，研究人员注意到多金属结核附近的氧气水平较高，这些结核是分布海底的金属和矿物的块状聚集体， 这成为了该气体海底生产的首个迹象。

But these continents, in terms of a strict geological definition  actually extend outward some way into the sea, in the form of shallow continental shelves, before  suddenly dropping down into the abyssal plains of the deep oceans.

但按照严格的地质定义，这些大陆实际上以浅大陆架的形式向外延伸到海中，然后突然坠入海平原。
