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已知物质一样黑—是深海军备竞赛。

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

从大气层到深海区， 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，深海区深度在 3,000 至 6,000 米之间。

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

深海区约占地球面积 70%。

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

从浅滩到海平面下 6000 米深海海沟，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.

而不是他们在电视上所说“深渊”。从技术上讲，深渊区深度在 3,000 到 6,000 米之间。

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、高压深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.

所些动物本质上是在园艺，因为如它们不样做，地球上些广阔无垠深海平原将变成巨大、停滞、 可怕污水坑。

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深海平原。

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.

在光合作用无法进行区域中发现任何氧气——例如深达6000米黑暗深海底——曾被认为是移动表面气体。

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.

种效应在热带地区最为明显，而在两极， 从表面到深海， 海水温度大致相同。

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.

公海深度差异很大， 但大部分从大陆架延伸到 3,000 至 6,000 米深地区，即所谓深海平原。

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.

巴伦在初步环境影响评估中投入了数百万美元，他将核所在深海平原描述为一个 “无生命沙漠”，采矿影响可能是极其微小。

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，研究人员注意到在多金属核附近氧气水平较高，些核是分布在海底金属和矿物块状聚集体， 成为了该气体在深海底生产首个迹象。

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.

但按照严格地质定义，些大陆实际上浅大陆架形式向外延伸到海中，然后突然坠入深海平原。
