蓝色星球 第二季
南极洲 Antarctica.
地球上最寒冷 最艰苦 最偏僻的大陆 The coldest, the harshest and the most remote continent on Earth.
尚无人类曾潜入 No human being has ever descended
南极洲周边的深海 into the depths that surround it...
直到现在 ..Until now.
探索深海和探索太空一样极具挑战 The deep ocean is as challenging to explore as space.
我们对大海最深处的了解 We know more about the surface of Mars
比对火星表面的了解还要少 than we do about the deepest parts of our seas.
现在我们可以潜入未知区域 Now we can dive these uncharted depths
探寻深藏在海洋深处的奥秘 to discover what secrets lie beneath.
沿着一座冰山的水下峭壁下潜 Sinking down beside the submerged wall of an iceberg,
我们进入一个无情的世界 we enter an unforgiving world.
这是地球上温度最低的水域 These waters are the coldest on Earth.
随着深度增加 水压不断上升 As we descend into the deep, the pressure increases relentlessly.
水面上投射下来的光只会消失不见 And the light from above all but disappears.
然而 令人难以置信 Yet, incredibly...
这里还有生命 ..There is life here.
我们之前以为 We might have expected that,
极地的海平面以下 deep beneath the surface of the polar seas,
应该十分贫瘠 the waters would be truly barren.
但实际上这里的生命丰富得难以想象 But in fact we find life here in unimaginable abundance.
这种物种丰富度并不只限于南极洲水域 Nor is such great abundance confined to Antarctic waters.
洋流将它们带到了 Currents carry this richness
全世界每一片深海 into the depths of almost every ocean around the world.
令人惊叹的是 深海中的生物数量 Astonishingly, in the deep sea,
比地球上其他任何地方都要多 there is more life than anywhere else on Earth.
深海
阳光逐渐消逝 大海暗了下来 The sunlight fades and the seas darken.
在太平洋水下二百米 Here in the Pacific, 200 metres down,
是我们完全陌生的世界 we enter an alien world.
暮霭地带 The Twilight Zone -
永世幽暗的海洋层 a sea of eternal gloom.
这里有奇怪的生物 There are strange creatures here.
火体虫 A pyrosome.
两米长的胶体长管 A tube of jelly two metres long
把浅层来的客人远洋白鳍鲨 that dwarfs a visitor from above -
衬托得非常娇小 an oceanic whitetip shark.
只有少量的光能射到这里 Only a tiny amount of light filters down this far.
想在这里生存就必须充分利用每一丝光线 Survival here means making the most of every last glimmer.
剑鱼 A swordfish.
它的眼睛和网球一样大 Its eyes are as big as tennis balls,
让它能在这万年的幽暗中看清周围 to help it see in the perpetual dusk.
乌贼 A squid,
这种乌贼只生活在这里 but this is one that lives only here.
它的右眼永远向下看 Its right eye looks permanently downwards.
左眼却要大得多 习惯向上看 But its left eye is much bigger and trained upwards
探寻浅层海洋猎物的轮廓 to detect the silhouettes of prey swimming nearer the surface.
怪不得它的外号叫"斜眼乌贼" No wonder it's nicknamed "the cockeyed squid".
还有更奇怪的 And even stranger.
这是后肛鱼 This is barreleye...
它的头部透明 充满液体 ..A fish with a transparent head
眼可以透过头骨向上看 filled with jelly so that it can look up through its skull.
现在我们知道暮霭地带 We now know that the Twilight Zone
是海洋中高达百分之九十的鱼类的避难所 is a refuge for an incredible 90% of all fish in the ocean.
只有在夜晚 成群结队的灯笼鱼 Only at night do vast shoals of lanternfish
才会前往海面寻找浮游生物为食 migrate to the surface to feed on tiny plankton.
天亮了 灯笼鱼会再游回深海 By day, they retreat back down here.
美洲大赤鱿 Humboldt squid.
体长两米 重达五十公斤 Two metres long and 50 kilos in weight.
和大多数乌贼一样 它们是贪婪的捕猎者 Like most squid, they're voracious hunters.
这群大赤鱿有上千只 There are hundreds of them.
它们发现了一群灯笼鱼 They've found a shoal of lanternfish,
藏在南美洲沿岸八百米深的水下 hiding 800 metres down, off the coast of South America.
它们的触手有强有力的吸盘 Their tentacles are armed with powerful suckers
可以抓住猎物 with which they grab their prey.
等到灯笼鱼被吃完了 And when there are no more lanternfish to be found...
它们便开始自相残杀 ..They turn on each other.
这只大赤鱿的触手里抓着一只小的同类 This squid has caught a smaller one in its tentacles.
为了不让别人看到自己的收获 To hide its capture from the rest,
它喷出黑色墨汁施展障眼法 it releases a smokescreen of black ink.
可是紧接着一只更大的乌贼发起了挑战 But then an even bigger one challenges it...
偷走了它的猎物 ..And steals its catch.
暮霭地带是美洲大赤鱿最爱的狩猎场 The Twilight Zone is the humboldt squid's favoured hunting ground.
它们很少去更深的地方 They seldom go deeper
很少进入下面永世黑暗的世界 into the world of perpetual blackness below...
午夜地带 The Midnight Zone.
距离海面一千米的深处 阳光无法到达 Two thirds of a mile from the surface, beyond the reach the sun.
黑色的虚无一望无际 A giant black void,
比世界上所有其他类型的栖息地加起来还要大 larger than all the rest of the world's habitats combined.
这里还有生命 There's life here.
但是我们并不了解 But not as we know it.
这些外星人般的生物能发出令人眼花缭乱的光 Alien-like creatures produce dazzling displays of light.
几乎所有动物都需要吸引伴侣 对抗天敌 Nearly all animals need to attract mates and repel predators.
在这里 把光作为语言十分普遍 This language of light is so widespread here
很有可能是整个星球上 that these signals are probably the commonest form
最广泛的沟通方式 of communication on the entire planet.
然而我们对这些信号一无所知 And yet we still know little about them.
猎人们点亮自己 Hunters illuminate themselves,
以此来吸引好奇的猎物 and by doing so attract inquisitive prey.
高体金眼鲷 This is fangtooth.
同等体型的鱼类中 它的牙齿最大 It has the largest teeth for its size of any fish.
它的头和身体遍布着压力感受器 There are pressure sensors all over its head and body
能够感知到周围水中的所有动静 which can detect anything moving in the surrounding water.
高体金眼鲷是午夜地带中食量最大的鱼 It's the Midnight Zone's most voracious fish.
但是猎物用光来分散注意力 But prey use light as a distraction.
释放发光墨汁作为假诱饵 A decoy of luminous ink.
深海之下 黑暗之中 Down here, in this blackness,
生物们超越了正常的时间规则 creatures live beyond the normal rules of time.
管水母类近乎永生 Siphonophores are virtually eternal.
它们不断地自我克隆 They repeatedly clone themselves.
有的最终长得比蓝鲸还要长 Some eventually growing longer than a blue whale.
深海之下也会下雪 Down here it snows.
云一般的有机残骸连续不断 Continuous clouds of organic debris
自上而下缓缓飘落 drift slowly down from above.
这是食物 各种各样的滤食动物 This is food, and a whole variety
靠此生活 of filter feeders depend on it.
水母 Jellyfish...
还有柔软的各种海参 ..And delicate sea cucumbers.
百分之一被它们放过的海雪 The 1% of marine snow they miss
最后都沉降在海底上 eventually settles on the sea floor.
经过几百万年的积累形成的泥层 Over millions of years it forms a layer of mud
厚达一千米 up to a mile thick.
这个空旷的平原覆盖了半个地球表面 It's an empty plain that covers half the surface of our planet.
深海海床乍看似乎毫无生机 The deep sea bed may at first appear lifeless...
但它却是一种独特的泥居生物的家园 ..But it's home to a unique cast of mud-dwellers.
圆头单棘躄鱼 The sea toad.
圆头单棘躄鱼是一种拥有着巨大嘴巴的伏击捕食者 It is an ambush predator with an enormous mouth...
并且极有耐心 ..And infinite patience.
圆头单棘躄鱼在海底生活的时间太久 This fish has been living for so long here
使得它的鳍进化成了更有用的东西 that its fins have changed into something more useful.
脚 Feet.
脚让它能在海底滑行 They help it shuffle about on the sea floor.
加利福尼亚面蛸 The flapjack octopus.
它在泥层地表盘旋 It hovers just above the surface of the mud
仔细查看 寻找虫子 as it delicately sifts through it, searching for worms.
但一旦遇到危险它就会弹射出去 But it can jet away at the first sign of danger.
灰六鳃鲨跟大白鲨一样大 A sixgill shark as big as a great white.
这只也许一整年都没有进食了 It may not have eaten for an entire year.
它用最少的能量在整片泥地巡游 It patrols the mud plains using a minimum amount of energy.
海面上有一具巨大的 High above, the carcass of a huge
鲸鱼尸体正在慢慢腐烂 sperm whale is slowly decaying.
这具尸体将成为深海生物的终极大奖 This will be a bonanza for the creatures of the deep.
物 三十吨的食物 Food, 30 tonnes of it.
这具尸体终于沉到了海底 Finally, it settles on the ocean floor.
很快就有生物发现了它的存在 And its presence is soon detected.
灰六鳃鲨有异常敏锐的嗅觉 Sixgill sharks have an exceptionally acute sense of smell.
在鲸鱼尸体沉底的二十五分钟后 Just 25 minutes after the whale's carcass arrives,
一只灰六鳃鲨发现了它 A sixgill finds it.
每咬一口尸体都向周围喷洒出血液 Each bite releases blood into the current.
这里有食物的消息传的很快 The news that food is here spreads quickly.
又来了两头饥饿的灰六鳃鲨 Two more ravenous sixgills arrive.
十二小时内 Within 12 hours,
来了七只鲨鱼 there are seven enormous sharks
争抢着能撕到一口食物的机会 jostling with one another as they compete to tear off mouthfuls.
没有谁打算退让 No-one is prepared to back off.
24小时后鲸鱼的尸体已被吃掉了三分之一 24 hours later and a third of the carcass has gone.
先到的这只吃的很饱才离开 The first arrival has gorged until it's completely full.
这一顿饭也许够它支撑一整年 This single meal may be enough to sustain it for a whole year.
现在清理队来了 Now the clean-up team arrives.
蜘蛛蟹的后腿上带着珊瑚 Spider crabs carrying coral in their hind legs,
科学家推测是用来做装甲的 presumably as makeshift body armour.
普通黄道蟹也来了 There are rock crabs here, too.
它们也许跟 They probably detected
鲨鱼同时发现了尸体 the carcass almost as soon as the sharks,
但它们走不快 But they can't move as fast.
一个月后 三十多种食腐动物 A month on, and over 30 species of
清理掉了尸体上最后一点 scavenger are clearing away the last
可食用部分 edible fragments.
但现在这些食腐动物引来了吃它们的捕食者 But now the scavengers are attracting their own predators.
大西洋叉尾带鱼这种习惯直立游泳的鱼类 Scabbardfish, habitually swimming upright,
正在一只一只地吃掉它们 are picking them off one by one.
鲸鱼的部分牙齿 Some of the whale's teeth
在骨架开始分解的时候 have been dislodged as the skeleton starts to
脱落了 fall apart.
四个月之后 除了骨头什么都没剩下 Four months later, there is nothing left but a few bones.
但对某些生物来说 But even they are food,
这也是食物 For something.
食骨蠕虫 Zombie worms.
食骨蠕虫通过分泌酸在骨头上腐蚀出通道 They tunnel into the bones by injecting acid.
吸收存留在骨头中的微量脂肪 And so reach the tiny amounts of fat that still remain there.
这也许需要几十年 但最终 It may take decades, but eventually
最后仅剩的骨架也会倒塌 the last of the bones will crumble
而这具三十吨的尸体 and the whole 30-tonne carcass
将被循环利用 will have been recycled.
鲸落只是在海底荒漠中 A whale fall is a temporary oasis
出现的临时绿洲 in the desert of the sea floor.
但也有一直存在的绿洲 But there are permanent oases here, too.
露在泥层外面的石头 Rocks projecting above the mud
给深海珊瑚提供了栖息地 provide anchorage for deep-sea corals.
在近六千米的深处 As far down as 3.5 miles,
珊瑚的种类数量比 there are more species of coral in the deep
热带浅海珊瑚礁上还要多 than on shallow tropical reefs.
在没有阳光的情况下 Without sunlight,
这些珊瑚完全依赖于水流带来的食物 they rely solely on food drifting in the current.
一年只能长头发丝那么宽 And they grow just a hair's breadth a year.
但是有些珊瑚可以活四千年 But some of them can live for 4,000 years.
这些珊瑚礁和它们浅海的亲戚一样 They, like their shallow water relatives,
为其他生物提供栖息的场所 provide homes for all kinds of other creatures.
珊瑚中生长着世界上最美的海绵 Growing among the corals is one of the most beautiful of sponges.
阿氏偕老同穴[俗名维纳斯花篮] This is Venus' flower basket.
这些海绵里有房客 These sponges have lodgers.
虾 Shrimps.
珊瑚礁区有许多捕食者 There are plenty of predators on the reef,
所以这两只虾很幸运 so the shrimps are fortunate.
它俩还是小虾的时候 Both this male and female were swept into this sponge
就被扫进了这丛海绵里 when they were tiny larvae,
每日还有海绵吃剩下的 along with the minute particles of
食物颗粒供养 food on which the sponge feeds.
这对虾从找到彼此开始就一直住在这里 They found each other and have been here ever since.
现在它们都成年了 Now they're full-grown
而且雌虾还带着卵 and the female is carrying eggs.
卵孵化之后 Once hatched, the larvae
幼虾们就会游出海绵墙 will swim out through the sponge's walls.
但是成年虾不会离开 But the shrimps will never leave.
它们走不了 They can't.
它们太大了没办法从海绵墙里出去了 They are now far too big to go out the way they came in,
但住在这里无疑要比 and no doubt they will live longer here than they would
在珊瑚礁上游荡活得久些 if they were wandering about on the reef unprotected.
为什么生物中最简单的海绵 But how one of the simplest of all animals, a sponge,
能够建造出如此复杂的结构 is able to build such a complex structure,
为虾们提供巨大的福利 to the great benefit of the shrimps,
原因依旧是个谜 is a mystery...
未来也肯定会令人惊奇 And surely a marvel.
但如今 它们永恒的世界已崩解成废墟 But today their timeless world is being reduced to rubble.
当过度捕捞将表层的海洋洗劫一空后 As overfishing empties the surface waters of the seas,
拖网渔船开始对更深处的海洋进行捕捞 trawlers have started to ransack the deep.
如今已经在这里生长千年的 Now countless numbers of the reefs
不计其数的珊瑚礁 that have flourished here for millennia
已成为废墟 lie in ruins.
随着时间流逝 海底的有机物逐渐腐烂 Over time, organic matter on the sea floor slowly decays...
生成甲烷 ..producing methane.
在墨西哥湾 In the Gulf of Mexico
这些喷出物中含有一种咸度极高的液体 these eruptions also release a super-salty liquid.
浓盐水 Brine.
浓盐水比海水重五倍之多 Five times heavier than seawater,
它们汇聚后沉积在海底 it accumulates in great pools on the sea floor.
很难理解眼前的景象 It's difficult to make sense of the sight.
有一个十五米深的咸水湖 A lake of concentrated saltwater, 15 metres deep
坐落在海底 at the bottom of the sea.
更奇怪的是 在它的边缘 Around its margin, perhaps even more strangely,
存在着大量生物 there is a profusion of life.
寿命长达一世纪有余的巨蚌 Giant mussels, that can live and grow for a century or more,
紧密地排列着 pack tightly together,
使得周边觅食的小虾和蹲龙虾相形见绌 dwarfing the shrimps and squat lobsters that feed around them.
食腐类动物合鳃鳗 Cutthroat eels, scavengers,
也来到咸水湖旁 come to the shores of the brine lake
寻找食物 in search of something edible.
有些甚至涉险进入咸水湖 Some even venture into the brine.
在咸水湖中逗留太久 Spending too long in it
会使鳗鱼中毒休克 can send an eel into toxic shock.
唯一的希望就是从上方逃脱 Its only hope is to rise above it.
它成功逃脱了 It manages to escape.
其它动物可就没这么幸运了 Others are not so lucky.
浓盐水使它们的尸体长久不腐 The brine embalms their bodies...
数十年间死于咸水湖的动物 ..And the casualties of decades
沉积在湖边 accumulate around the margins.
然而海洋深处还有更加恶劣的环境 But parts of the deep are even more hostile.
有些地方 巨大的裂缝纵横海底 In places, gigantic cracks stretch for many miles
绵延数千米 across the ocean floor...
峡谷向地心深处延续 ..Canyons that plunge towards the centre of the Earth.
测量船的扫描装置 Scans from survey vessels
可以将壮阔的海底奇观 make it possible to graphically reconstruct
重建成图像 an image of this vast submarine landscape.
位于太平洋的马里亚纳海沟 The deepest of all, at almost seven miles,
它是海洋的最深处 最深达1.1万米 is the Mariana Trench in the Pacific Ocean.
即使是珠穆朗玛峰也能沉没于此 Even Mount Everest could disappear inside it.
在这些纵横相交错的海底沟壑中 Down here, in these deep ravines,
人们曾经一度以为没有任何生命能够存活于此 it was once thought that nothing whatever could possibly survive.
但即使在这里也有生命存在 But there is life even here...
一种海蛞蝓 ..A kind of sea slug.
俗称”海猪" A so-called "Sea pig".
它们和一些其他的简单生物 They, and other simple creatures, manage to survive
依靠少量漂流至此的食物生存 on the minuscule amount of food that drifts down here.
就像这些海星 Like this starfish,
它们可以承受相当于五十架巨型喷气式飞机 they can withstand pressure equivalent of 50 jumbo jets
叠在一起产生的压力 stacked on top of one another.
远程摄像探测器拍摄到的 A remote camera probe reveals
最奇特非凡的发现莫过于 the most extraordinary discovery of all...
空灵狮子鱼 ..The ethereal snailfish.
它们生活在八千米深处 At five miles down,
这是目前已知生活在最深处的鱼类 this is the deepest living fish so far discovered.
无法想象像鱼类这样复杂的生物 No-one imagined that an animal as complex as a fish
可以如此极端压力下生存 could exist in such extreme pressures.
从海洋最深处 From the greatest depths
到暮霭地带 to the uppermost limit of the Twilight Zone,
似乎深海之中没有任何 it seems that there is nowhere in the deep sea
生物无法生存的环境 where life of some kind can't survive.
而且我们现在认为深海很可能是 And we now think that the deep sea may well be
地球生命的发源地 where life on Earth began.
在这里 这个隐藏于地球中 Here, in a world hidden
地质特征最壮观的世界 within the greatest geological feature on Earth...
这条水下山脉 ..Running right down the middle of the world's oceans,
沿世界海洋的中心蔓延 横跨整个地球 an underwater mountain range, spanning the entire globe.
这就是大洋中脊 The Mid-Ocean Ridge.
在南太平洋 In the South Pacific,
海底四分五裂 the ocean floor is being torn apart.
地球上超过四分之三的火山活动 Over three quarters of the planet's volcanic activity
都发生在海洋深处 occurs in the deep...
而海底的火山活动几乎都发生在大洋中脊 ..Almost all of it along the Mid-Ocean Ridge.
但是这威力巨大的火山活动也能带来很多好处 But from this titanic violence come great riches.
气体和滚烫的海水从缝隙中喷涌而出 Gases and scalding water gush up through the crevices.
喷射物中的矿物质冷凝堆砌形成了狭缝 Minerals condensing from these jets build up great chimneys...
形成热液出口 hydrothermal vents.
这个三十多米高的热液出口 This one, 30 metres tall,
被命名为哥斯拉 has been named Godzilla.
令人惊叹的是 就我们所知 Astonishingly, we now know
热液出口的生物和热带雨林中的一样丰富 that they hold as much life as tropical rainforests.
在某些地方 一平方米内的 In places, half a million individual animals
种群数量甚至达到五十万 are crammed into a single square metre.
它们完全依赖细菌填饱肚子 They depend entirely for their food on bacteria.
而那些细菌则以溶解在热流中的化学物质为食 And they feed on chemicals dissolved in the searingly hot fluid.
蟹类把覆盖在壳上的细菌层当作食物 Crabs consume the bacterial mats that coat their shells.
还有些动物甚至 Others maintain bacterial cultures
在自己体内培养繁殖细菌 actually within their bodies.
虾的口器中就有这样的细菌群落 Shrimps carry such cultures in their mouthparts,
但这样的策略会给虾带来危险 but that is a strategy fraught with danger.
为了给这些微生物提供营养 To provide sustenance for these microbes
虾不得不冒着被活活煮熟的危险 the shrimps must dash into the hot vents...
冲进热液出口 ..And that risks being boiled alive.
在过去的十年中 In the last decade
人们发现的热液出口数量翻了一番 the number of hydrothermal vents discovered has doubled.
每个热液出口都有其特征和生物群落 Every one has its own unique character and community.
但坐落在大西洋中的这一出口或许最为重要 But perhaps the most important one of all is in the Atlantic.
它被命名为"失落之城" It has been named "The Lost City".
在这些六十米的高峰内 Within its 60-metre towers,
一些不同寻常的事情悄然发生 something truly extraordinary is taking place.
在极端的压力和温度中 碳氢化合物 Under extremes of pressure and temperature, hydrocarbons -
即构成所有生物基本成分的分子 the molecules that are the basic component of all living things -
可以自然形成 are being created spontaneously.
事实上 许多科学家现在相信 Indeed, many scientists now believe
四十亿年前 that life on Earth may have begun
地球上的生命也许就产生于 around a vent like this,
像这样的热液出口 four billion years ago.
现在我们知道木星和土星的卫星上 We now know that there are deep seas
也有深海存在 on the moons of Jupiter and Saturn.
如果生命能在这样极端的环境中生存 If life can exist under such extreme conditions down here,
在其他星球也同样有可能 then surely it could exist somewhere out there.
探秘蓝色星球
摄制组花了超过一千小时拍摄深海景观 The team spent more than 1,000 hours filming in the deep ocean,
使用的多是阿卢西亚号勘探船和同系列潜水艇 mostly from the research Vessel Alucia and her twin submersibles,
深海漫游者号和天底号 Deep Rover and Nadir.
其中野心最大的就是驶往南极洲 Their most ambitious mission was to Antarctica,
拍摄一千米以下的海底生物 hoping to film life two thirds of a mile down,
这是从未有人尝试过的举动 something never attempted before.
我们真的不知道下面会有什么 We honestly do not know what we're going to find down there.
奥尔拉·多尔蒂 制片人
我们要去的地方是一片未知之地 We're going to a place that has never been explored.
那里可能什么也没有 也可能有很多生物 There could be nothing, there could be a carpet of life,
也可能是别的情况 谁知道呢 there could be anything in between. Who knows?
这在技术上是一项重大挑战 It's a huge technical challenge.
那里的水温只有零下1.8摄氏度 The water temperature here can reach minus 1.8 Centigrade.
没人能确切地知道潜水艇在这样 No-one knows for sure how the subs will cope
极端的环境中会发生什么情况 with this extreme environment.
-好 我准备把水吸上来了 -好 - OK. Right, I'm going to soak it up. - OK.
首次潜水半小时后 Just half an hour into the very first dive,
潜水艇舱内地面上出现了一小滩水 a puddle is forming on the floor of the sub.
奥尔拉确认了这是海水 Orla confirms it's seawater.
收到 我正准备将这滩水吸干 Yeah, Roger. I'm just try to soak up this puddle of water,
看看会不会再进水 and then see if any more comes.
他们必须得找到裂缝 迅速补好 They must find the leak and repair it fast.
-你准备把我上面那个打开吗 -好 - Are you going to knock that over my...? - Yeah.
潜水艇漏水了 而你在450米深的海下 You're at 450 metres in a small bubble and water's coming in.
径直回到海面也需要半个小时 That's a half an hour straight shot back up to the surface.
你就会想 You're kind of thinking about,
"这样会进满水吗 "Are we going to fill up with water?
如果那样的话 根本无法逃生" And if we are, there's no way out!"
好 Yeah.
潜水艇驾驶员训练有素 能处理各种突发事件 The sub pilots are well drilled for emergencies.
-递过来 -好 - Just pass them over. - Yeah.
拉尔夫很快就找到了漏水处并修复完毕 Ralph quickly finds the flood and fixes it.
他把这件事处理的好像非常普通的状况 He made it all seem absolutely ordinary and normal and,
"交给我 别担心" "I've got this covered, don't you worry,"
不到二十分钟他就搞定了 and within 20 minutes, he did.
南极海峡的海水可能非常富庶 The waters of the Antarctic Sound are potentially rich
但也异常凶险 but also treacherous.
南极海峡还有个不祥的名称 "冰山巷" The Sound is ominously known as "Iceberg Alley".
我们得找个没有冰山 We've got to find a place
能让潜水艇安全上浮下潜的地方 where we can get the submarines down and up safely
詹姆斯·哈尼伯恩 执行制片人
不然冰山出现会撞到他们 hout any icebergs coming along and bowling them over.
我感觉这会有点像 I've got a feeling it's going to be
《太空侵略者》这款游戏 a bit like a game of Space Invaders.
一立方米的冰重达一吨 A metre cube of ice weighs a tonne.
我们要把冰山周边的棱角磨掉 但冰块很易碎 You start sort of grinding that around the sphere, it's delicate.
巴克·泰勒 潜水团队负责人
就像是一个大复活节彩蛋 It's like a big Faberge egg.
其中一次下潜 One dive brings them right
他们潜到了一座冰山的正下方 up to the underside face of an iceberg.
有的冰山和小型车一般大 There are icebergs up there that are the size of a small car,
有的有海德公园那么大 and then there are icebergs up there that are the size of Hyde Park.
非常巨大 Enormous.
这里的情况瞬息万变 Conditions here can change in an instant.
船长通过无线电和潜水艇联系 The captain radios down to the subs.
我之前担心冰山会砸到潜水艇上 现在遇到了
收到 Yeah, Roger that.
现在有两座大冰山 We've currently got a couple of big icebergs
在沿海峡下漂 coming down the channel,
看上去他们要相撞了 and it looks like they're on a collision course.
他们清楚地听见了两座冰山在他们上方相撞 The impact of two icebergs colliding overhead is clearly heard.
我听到了 I heard those.
由于冰山相撞 天气开始急剧变化 With icebergs colliding above and the weather turning fast,
摄制组迅速召回了潜水艇 the subs are quickly recalled.
他们的尝试再一次受到了阻挠 Once again their efforts are thwarted.
终于 两周后 时机来了 Finally, after two weeks, conditions are just right.
摄制组又一次尝试进行潜入冰山巷下 Once again the team attempt their 1,000-metre dive
一千米处 in Iceberg Alley.
开始下潜一小时后 他们终于接近了目标 An hour after leaving the surface they close in on their goal.
999米 999.
指挥中心 指挥中心 Control, control.
这里是天底号 This is Nadir
我们在水深一千米处 on bottom, depth - one-zero-zero-zero metres.
收到 水深一千米处 Roger. Depth - 1,000 metres.
-指挥中心通话完毕 -破纪录了 - Control out. - New record!
载人潜水艇首次下潜到南极洲水下一千米处 First manned sub dive to 1,000 metres in Antarctica!
在海洋底部 世界尽头 At the bottom of the ocean, at the end of the world,
他们发现这里的生物数量十分惊人 the amount of life they find is astonishing.
同样令人震惊的是 But they are equally astonished to find that,
距海面一千米以下的地方 two thirds of a mile from the surface,
冰山依旧是一大隐患 icebergs are still a danger.
冰山融化时石头会从冰山下落下 Rocks can drop from them as they melt,
有一块正砸在潜水艇前方 and one lands right in front of the sub.
我觉得潜水艇里的人 I don't think many people who are diving subs
不会想到自己会被巨石砸中 ever consider big lumps of rock landing on them.
这种危险并不常见 It's, it's not your normal risk.
如果这个砸到了潜水艇 If it had hit the sphere,
潜水艇表面很有可能留下划痕 there's a good chance it would have put a nice scratch down it.
而如果是重达十五 二十吨的东西砸到潜艇 If something of ten, 15, 20 tonnes had hit the sub,
潜艇就会被彻底砸毁 it would completely destroy it.
但在接下来的几次下潜中 But over the following dives
摄制组发现正是这些落下的石头 the team learns it's these very drop stones
令南极洲深海海床变得富饶 that enrich the Antarctic deep sea bed,
为生物提供了稳固的生长场所 creating firm anchor points for life to thrive.
这次经历也证明了想要好好观赏 Proof that the only way to fully appreciate
复杂多变的深海生物的唯一办法就是 the complexity and abundance of life in the deep
亲自去看一看 is to go there ourselves.
下期节目 我们将前往热闹非凡的珊瑚礁海域 Next time, we travel to bustling coral reefs.
在这里 动物们要全力以赴 Here, animals must go to extraordinary lengths
才能在这拥挤的国度中战胜对手 to get ahead of the competition in these crowded cities.
