组成一支五千只海豚的超级大军 in a super-pod, 5000 strong.
极大地增加了它们找到食物的机会 That maximises their chances of finding something to eat.
和其它生存于此的生物一样 Like all who live here,
它们必须竭尽全力 they must go to extraordinary lengths
才能在这片碧海蓝天之中存活下来 to make their home in the big blue.
碧海蓝天
荒芜的海洋中也会出现难得一见的生机盎然 There are rare moments when these empty seas can explode with life.
灯笼鱼 栖息在哥斯达黎加沿岸太平洋海域 Lanternfish, off the Pacific coast of Costa Rica.
它们仅比米诺鱼大一点点 They're scarcely bigger than minnows,
但是它们的数量弥补了在体型上的不足 but what they lack in size they make up for in numbers.
灯笼鱼是数量最多的鱼类之一 They are one of the most numerous fish anywhere.
它们通常只会在夜晚才会来到海面觅食浮游生物 Normally, they only come to the surface at night, to feed on plankton,
但是这群数量庞大的灯笼鱼在白天就已经聚集起来 but this immense shoal has risen during the day,
几乎可以肯定是为了产卵做准备 almost certainly in order to spawn.
对海豚们来说 这可能是饱餐一顿的好机会 For the dolphins, this would be a bonanza.
它们使用回声获得了鱼群的位置 They have located the shoal using their echo-sounding calls.
但是得尽早赶到才行 But they have to get to it quickly.
它们可不是这里唯一的捕食者 They are not the only hunters here.
黄鳍金枪鱼同样感知到了鱼群的位置 Yellowfin tuna have also detected the shoal.
在它们后边的是 And behind them,
有着两米翼展的蝠鲼 with their two-metre wingspans, mobula rays.
旗鱼 海洋中速度最快的鱼类之一 Now sailfish, one of the fastest fish in the sea,
现在也加入到了争夺中 have joined the chase.
灯笼鱼随时都可能回到深海 The lanternfish may return to the deep at any moment.
但现在海豚大军已经到了 But now the dolphins have got here.
它们在鱼群底部游走 将其赶到海面 They swim beneath the shoal, pinning it to the surface
迫使灯笼鱼更紧密地聚在一起 and forcing the lanternfish to pack more closely together.
现在海水都开始沸腾起来了 And now the sea begins to boil.
金枪鱼以超过60公里的时速冲向鱼群 The tuna charge into the shoal at over 40mph.
游得最慢的蝠鲼最后赶到 The slower-swimming rays arrive at last.
张着它们巨大的嘴 With their immense mouths agape,
每口吞掉的灯笼鱼数以百计 they scoop up the lanternfish by the hundred.
现在鱼群都已经散开了 The shoal has now been largely dispersed,
而旗鱼收拾掉了幸存的小鱼 and the sailfish pick off the survivors.
在短短的十五分钟里 In just 15 minutes,
剩下的只有碎纸屑一般的银色鳞片 all that's left is a silvery confetti of scales.
但在这里 这样的盛宴实属罕见 But here, such feasts are only too infrequent.
海豚表现出了极大的耐力 Whilst the dolphins perform great feats of endurance,
而其他生物为了在这海洋荒漠中寻找食物 others are driven to even greater extremes
更是将自己推向了极限 to find food in this ocean desert.
一头沉睡的庞然大物 A sleeping giant.
抹香鲸 A sperm whale.
这一家正为下次捕食养精蓄锐 This family is resting between bouts of feeding.
谁知道这地球上最大的脑袋里 Who knows what the owners
做的是什么梦呢 of the biggest brain in the planet dream about.
一头母鲸带着幼崽 One has a calf.
幼崽约两周大 It's about two weeks old
还在依赖着母亲的母乳 but still dependent on its mother's milk.
它饿了 It's hungry.
它用脉冲声与母亲沟通 It communicates with its mother using a pattern of clicks.
但是它母亲睡得太香了 But its mother slumbers on.
幼崽身上被胭脂鱼覆盖 The calf, covered in sucker fish,
幼崽太小 还无法自己摆脱掉它们 of which it can't yet rid itself,
只能耐心等待 has to be patient.
鲸鱼们睡醒精神抖擞 动身捕食 Sleep over and refreshed, the whales move on.
抹香鲸不会等着它们的猎物浮到海面 Sperm whales don't wait for their prey to rise to the surface.
而是直接潜到深处 寻找食物 They swim down into the depths to find it.
它们做几次深呼吸 They take a series of heavy breaths...
使血液氧气含量饱和 to saturate their blood with oxygen.
然后开始下潜 Then down they go.
全家出动一起下潜寻找鱿鱼 This entire family dives together in search of squid.
母亲会把自己的体能推向极限 A mother will push her body to the limits of her endurance,
但是它的幼崽已经很难跟上步伐了 and already it's hard for her calf to keep up with her.
幼崽尽可能地紧跟它的母亲 The calf sticks to its mother as closely as it can...
时不时触碰一下母亲 touching her frequently,
似乎这样才安心一些 as if for reassurance.
到达水下三百米时 But 300 metres down,
幼崽好像憋不住气了 it seems the calf can't hold its breath any longer.
在它们幼年的时候 幼崽们还法参与捕猎 In their early years, calves are forced to sit out the hunt.
成年的抹香鲸们则继续下潜 The adults continue their dive.
母鲸会变换它的声音 The mother changes her calls
变成一系列大而急促的脉冲声 into a series of louder and more rapid clicks.
她现在利用声纳来追捕鱿鱼 She's now using sonar to hunt down shoals of squid.
八百米时 一连串脉冲声过后 At 800 metres, a burst of clicks.
一片死寂 Then silence.
它抓到了猎物 She's made a catch.
捕猎者能进行长达一小时的下潜捕食 The hunters could be away for as much as an hour.
最终 母鲸从深海满载而归 Finally, the mother returns from the deep.
带着一肚子的鱿鱼 with a stomach full of squid.
漫长等待过后 饥饿的幼崽终于可以喝到母乳了 After a long wait, this hungry calf can take some milk.
母乳是哺乳动物制造的最有营养的东西之一 It's one of the richest produced by any mammal,
幼崽一天要喝上能装满一浴缸的母乳 and the calf guzzles a bathful of it a day.
幼崽可能要花上六年时间才能精通深海潜水的艺术 It may be six years before a calf masters the art of deep diving
做到自己捕猎觅食 and is able to find food for itself.
茫茫大洋的荒芜让捕食者的生活如此艰辛 The emptiness of the big blue is what makes life so hard for hunters.
但正是这种荒芜 But it's this emptiness
使得猎物们相对安全了一些 that makes it comparatively safe for prey.
一只幼龟 几天以前刚刚破壳 A baby turtle, hatched just days ago,
正在离开拥挤而充满危险的近海水域 is leaving the crowded, dangerous waters of the coast
向海洋中心进发 and heading for the open ocean.
我们直到近期才得以解开 Only recently have we begun to solve the mystery
幼龟们早年的行踪动向之迷 of where baby turtles disappear to in their early years.
一开始 它们以浮游生物充饥 To start with, they fill their little stomachs with plankton.
但很快它们就需要更能饱腹的食物 But soon they need something more substantial.
每片海域 在距海岸数百公里处 Hundreds of miles offshore, in every ocean,
都有年轻的离群者组成的群落 there are communities of young castaways.
任何漂浮物都能吸引它们的注意 So anything that floats attracts them.
比如一段浮木 A log.
它可能已经在海中漂浮很多年了 It may have been at sea for several years,
而且已经是一个小群落的中心了 and it has already become the centre of a small community.
年幼的河豚鱼们也为同样的目的而来 Young puffer fish are here for the same reason.
一段浮木正是这只幼龟一直找寻的 A floating log is just the kind of refuge
完美避难所 this young turtle has been looking for.
这里 附着其上的不仅有海草 还有藤壶 Here, there's not only seaweed on which to graze, but barnacles.
但保持隐蔽很重要 But it's important to stay under cover.
一只年轻的远洋丝鲨也在这里出没 A young ocean-going silky shark is here, too.
它正在学习了解什么好吃 It's learning what tastes good.
什么不好吃 And what doesn't.
我们现在知道了 We now know that many young turtles
很多幼龟会在这种地方生活很多年 stay in such places for several years,
直到成年 until adulthood.
尽管这意味着会面临来自大海巨浪的猛烈袭击 Even if it means facing the full force of the high seas.
太阳炙烤着深蓝的大洋 The sun beating down on the deep blue
使表面的海水升温继而蒸发 warms the surface waters so that they evaporate.
随着蒸汽不断上升 凝结成云 As the vapour rises, it condenses into clouds.
它们迅速形成巨大的塔状乌云 They rapidly build into gigantic, burgeoning towers,
并最终产生猛烈的暴风雨 which eventually generate violent storms,
横跨超过1600公里 some 1,000 miles across.
飓风横扫大海 Hurricane-force winds sweep across the open ocean,
掀起高达30米的巨浪 building waves that can rise to 30 metres tall.
很多过往船只在这里下沉消失 Out here, ships have been known to sink without trace.
每年有1.3亿集装箱漂洋过海运往各地 130 million containers are shipped across the oceans every year.
平均每天有4只沉入海中 And on average, four of them fall into the sea every day.
1992年 几只装载沐浴玩具的集装箱掉入大海 In 1992, a few were lost that contained a consignment of bath toys...
里面装有七千只像这样的塑料小鸭 including 7,000 plastic ducks like these.
它们在距阿拉斯加1600公里处展开了旅行 They started their travels 1,000 miles off Alaska.
一些横跨太平洋抵达了澳大利亚 Some drifted right across the Pacific Ocean and reached Australia.
一些被带往北方 Others were carried north
到达俄罗斯和阿拉斯加之间的海岸上 and landed on shores between Russia and Alaska.
甚至还有的漂流到了极北地区 They even found their way into the High Arctic.
其中一只小鸭 在海中漂流了15年 One duck, having been at sea for 15 years
跨越了三大洋 and crossing three oceans,
最终到达了苏格兰西海岸 eventually landed on the west coast of Scotland.
它们的旅行路线生动地描绘了洋流的网络是如何 Their travels vividly illustrate how a network of currents
将所有的海洋联系起来形成一个巨大的循环系统的 connects all our oceans into one gigantic circulatory system.
许多大洋深处的定居者们依靠这些洋流 Many of the inhabitants of the big blue rely on these currents
引领它们去往食物所在之处 to carry them to feeding grounds.
蓝鲨 The blue shark.
每年可以游超过8000公里 It travels over 5,000 miles a year,
借助洋流的力量 由宽阔的翅状鳍支撑着 riding on the currents, supported by its broad wing-shaped fins.
这一只可能已经两个月没有进食了 This one may not have eaten for two months.
但是洋流可以带来十公里外脂肪油的气息 But the currents can carry promising traces of fatty oils
并引领它到达下一餐的地点 from many miles away and will lead it to its next meal.
经过几天的跋涉 食物的味道愈加浓郁 After days of travel, the smell of food gets stronger.
一只最近被船撞死的鲸鱼 A dead whale, recently struck by a ship.
这是一次一饱口福的机会 This could be a real feast,
但是蓝鲨必须小心行事 but the blue shark must be cautious.
大白鲨 Great white sharks...
体重比蓝鲸的十倍 ten times heavier than a blue...
对鲸鱼的尸体非常感兴趣 are highly possessive around a whale carcass.
大白鲨渴望吃掉富含能量的鲸脂 Great whites are eager to feed on energy-rich whale blubber,
我们现在发现这是它们饮食的主要组成部分 which we now know forms a major part of their diet.
一旦大白鲨填饱了肚子 Once the great white has had its fill,
小型鲨鱼 像蓝鲨 smaller sharks, like the blue shark,
开始进食尸体的剩余部分 tackle what's left of the carcass.
随着鲸油的味道越传越广 As the oils from this dead whale spread more widely,
越来越多的蓝鲨出现了 more and more blue sharks appear.
几天之内 遗骸上的鲸脂就会被瓜分殆尽 Within days, the carcass will be stripped of its blubber.
随后无法再靠自身油脂保持浮力 Then, no longer kept buoyant by its oil,
鲸尸将沉入大海深处 it will sink into the depths below.
蓝鲨 因其补充了脂肪的储备 The blue, with its reserves of fat replenished,
又可在不进食的情况下存活两个月 can now survive for another two months without eating.
超过一半以上的海洋生物顺着洋流漂游 Over half of all animals in the open ocean drift in currents.
海洋遍布水母 Jellyfish cross entire oceans
任何缠上它们触须的生物都成为它们的食物 feeding on whatever happens to tangle with their tentacles.
有些直径可达一米 甚至两米 Some can grow to a metre, even two metres, across.
而当幸运来临 And when, by lucky chance,
遇到了一片富含浮游生物的水域 they encounter a patch of sea rich in plankton,
它们的数目会暴增 their numbers explode.
这个策略是如此成功 It's such a successful strategy
以至于水母成了地球上最常见的生命形式之一 that jellies are one of the most common life forms on the planet.
但是在众多水母中 有一样看似平淡无奇 But among the jellies, and looking somewhat like them,
却相当复杂且危险的生物 is a rather more complex and sinister creature.
葡萄牙军舰水母 The Portuguese man-o'-war.
它依靠一个鼓满气的 It floats with the help of a gas-filled bladder,
上有垂直薄膜的膀胱漂浮着 topped by a vertical membrane.
它用其作帆 With that serving as a sail,
在波浪中保持着平稳航线 it maintains a steady course through the waves.
它身下拖着的长线 Long threads trail behind it,
有的长达30米 some as much as 30 metres long,
每条都有数千个刺细胞 each is armed with many thousands of stinging cells.
而一条触手就可以杀死一条鱼 A single tentacle could kill a fish,
或极少数情况下 一个人 or in rare cases, a human.
但在其致命的触手间 But among its lethal tentacles
徘徊着一只咬食触手的军舰鱼 lurks a man-o'-war fish that feeds by nibbling them.
尽管这鱼对刺细胞有些抵抗力 Whilst this fish has some resistance to the stings,
它也必须极度小心 it must still be extremely careful.
其他大多数鱼就不这么幸运了 Most other fish are not so lucky.
一只触手抓住了这条鱼 并开始收线 A tentacle has caught this one and reels it in.
它已经被麻痹了 It's already paralysed.
专门生有肌肉的触手将受害者转移到 Specialised muscular tentacles transfer the victim to
其他消化猎物的触手中 用强性化学物质将其液化 others that digest the catch, liquefying it with powerful chemicals.
最终剩下的... Eventually, all that is left...
只是一具带鳞外壳 is a scaly husk.
这种贪吃的军舰水母 This voracious man-o'-war
一天内可能会捉到100多条小鱼 may collect over 100 small fish in a day.
大多数情况下 碧海看上去毫无特点 For the most part, the big blue seems featureless...
就是一个海风呼啸 不为陆地所阻挡的地方 a place where the winds blow, uninterrupted by land.
但其表层之下有延绵山脉 But beneath the surface there are long mountain ranges,
幽深海沟以及火山孤峰 deep trenches and isolated volcanic peaks
让它远比人眼所见的更为包罗万象 that make it far more varied than the human eye can see.
我们只是在细致探索 We are only just discovering in any detail
碧海的居民们如何利用它 how the inhabitants of the big blue exploit that.
一条正在进行特殊之旅的孤独鲸鲨 A lonely whale shark on a special journey.
它有一架小型飞机那么长 She is as long as a small aircraft
重20多吨 and she weighs over 20 tonnes.
像许多鲨鱼一样 Like many sharks,
它不产卵而是分娩活体幼崽 she does not lay eggs but gives birth to live young.
它鼓鼓囊囊的肚子里装着多达300只幼崽 She carries up to 300 of them in her swollen belly.
它可能是海中最大的鱼 She may be the biggest fish in the sea,
但我们至今仍未找到鲸鲨分娩的地方 but the place where whale sharks give birth has not yet been found.
但今天 我们可能离解开这一谜团更近了一步 Today, however, we may be a step closer to solving this mystery.
我们已经知道大量鲸鲨 We have known that great numbers of whale sharks,
会在一年中的特定时间 at certain times of the year,
出现在加拉帕戈斯岛附近 appear around the Galapagos Islands.
赤道附近的南美洲西海岸岛屿
它们在这里围绕着一个 Here they assemble around a tiny islet
从极深海水中突然冒起的小岛聚集起来 that rises abruptly from particularly deep water.
此岛名为达尔文岛 It's known as Darwin Island.
在这里 打着旋的洋流将养分从深海带上来 Here, swirling currents bring up nutrients from the deep,
海水营养非常丰富 so enriching these waters that
吸引了四面八方的鱼大量聚集 they attract great concentrations of fish from far and wide.
数千条锤头鲨也在此聚集 Thousands of hammerhead sharks also assemble here.
它们几乎全是雌性 They are nearly all female.
看起来也像是来这里繁衍生息的 They, too, it seems, have come here to breed.
鲸鲨受到了热烈的欢迎 The whale shark receives an extraordinary welcome.
体长3米的丝鲨 Silky sharks, themselves three metres long,
从鲸鲨粗糙的皮肤上弹擦而过 bounce against her rough skin...
这也许是为了蹭掉它们可能有的寄生虫 perhaps to scrape off any parasites they might have.
这些鲨鱼对任何新生幼崽而言都会是威胁 These sharks could be a danger to any newly born young.
所以也许是为了避开它们 So, perhaps to avoid them,
鲸鲨潜到 the whale shark dives...
约600米以下 down to around 600 metres.
然后它大概会在那里生出幼崽 And there she may release her young.
在这个 In these great depths,
离觅食于上方水域里的掠食者很远 away from the predators that hunt in the waters above,
并且有着充足的食物的深处 and with abundant food,
它的幼崽们才能长大 并最终分散到海洋各处 her babies could grow and eventually disperse.
从来没有人 No-one, it is true,
在这些鲜有人至的深渊中看见过幼鲸 has ever seen young ones in these little-visited depths.
但每年不出所料 数百条鲸鲨 But the fact that hundreds of expectant whale sharks
都会来这里的事实 come here every year,
就是铁证 证明这里某个地方 is strong evidence that somewhere here
坐落着海中最大鱼类的育婴室 lies the nursery of the biggest fish in the sea.
大约有3万座相当大的岛屿 There are almost 30,000 sizeable islands
散布于世界海洋中 scattered across the world's oceans.
其中之一就是南乔治亚岛 One of them is South Georgia,
对那些被迫去陆地上繁衍后代的海洋居民而言 an ideal place for those ocean dwellers
这是理想的去处 who are compelled to land in order to breed.
一只信天翁漫游着 The wandering albatross.
它可能会花长达一年的时间在海上不停地飞 It may spend as much as a year continuously at sea.
一边觅食 一边依靠着3.5米宽的翅膀滑翔 Searching for food, gliding on wings that are 3.5 metres across -
这是现存鸟类最大的翅膀 the biggest of any living bird.
所有一万六千只漫游者在南乔治亚岛筑巢 The entire world population of 16,000 wanderers nest on South Georgia
以及在南大洋其他六七个 and half a dozen or so of the other smaller islands
较小岛屿上筑巢 that lie in the Southern Ocean.
正值春季 这只鸟正返回 It's spring and this bird is returning
它一直住的巢穴 to the nest site it's always used.
它的终生伴侣早已在这了 Its lifelong partner is already here.
在南乔治亚岛 In South Georgia,
个别的鸟已经被终生研究 individual birds have been studied for their entire lives,
这些研究揭示了老鸟夫妇们在30岁后期 revealing that older pairs, in their late 30s,
会竭尽所能 will go to extraordinary lengths
让其幼雏赢在生命的起跑线上 to give their young the best possible start in life.
这只雏鸟已经几周大了 This chick is now several weeks old,
但仍然身披保暖的绒毛 but still has its warm, downy coat.
雏鸟需要父母经常反刍鱼和乌贼来喂养它 The chick will need a regular supply of regurgitated fish and squid.
由于开阔的海洋中食物缺乏 With food so scarce in the open ocean,
父母可能要搜索几千甚至上万平方公里的范围 both parents may have to scour thousands of square miles

年迈的父母在南极的寒冬中含辛茹苦 Ageing parents struggle on all through the Antarctic winter

大约130天后 After some 130 days,
小家伙身上的绒毛逐渐变成了羽毛 the youngster begins to replace its down with flight feathers.
终于在成鸟产卵的九个月之后 Finally, nine months after their egg was laid,
这只雏鸟准备好离开了 this chick is ready to leave.
在它们近年来抚育的幼鸟当中 Of all the chicks they've reared in recent years,
这样备受宠爱的幼鸟是将成为生存几率最大的一只 such a favoured chick will have the best chance of survival.
但也是将是它们抚育的最后一只 But it will also be their last.
年老的父母已经殚精竭力 Elderly parents never recover from their exertions.
它们很快就要离开这座岛屿 杳无踪影 They will soon leave this island, never to be seen again.
在无际的海洋中存活下来 Surviving in the open ocean
一直都是对动物们生理极限的挑战 has always tested animals to the limit...
然而今天它们又有了新的威胁 but today they face a new additional threat.
塑料 Plastic.
就在一百多年前 Just over 100 years ago,
我们发明了一种奇妙的材料 we invented a wonderful new material
可以被塑造成各种形状 that could be moulded into all kinds of shapes
我们千方百计地确保它耐磨损 and we took great trouble to ensure that it was hard-wearing,
抗腐蚀 甚至永不损毁 rot-proof and virtually indestructible.
如今 每一年 Now, every year,
我们都要把八百万吨塑料倾倒入海中 we dump around eight million tonnes of it into the sea.
这些塑料会缠住大量的海洋生物使其溺水身亡 Here, it entangles and drowns vast numbers of marine creatures.
然而塑料可能还会产生更为广泛深远的影响 But it may have even more widespread and far-reaching consequences.
一群短鳍巨头鲸 A pod of short-finned pilot whales.
它们以家庭为单位生活 They live together in what are, perhaps,
有着整个海洋中最为亲密的家庭关系 the most closely knit of families in the whole ocean.
今天 欧洲大西洋沿岸 和任何其他地方一样 Today, in the Atlantic waters off Europe, as elsewhere,
它们不得不和塑料一起生活在海洋中 they have to share the ocean with plastic.
一头母鲸抱着她新生的幼崽 A mother is holding her newborn young.
它已经死了 It's dead.
母鲸仍不肯撒手 She is reluctant to let it go
它衔着死去的幼崽已经好几天了 and has been carrying it around for many days.
塑料分解时 会与其他污染物混合 As plastic breaks down, it combines with these other pollutants
被大量海洋生物吃掉 that are consumed by vast numbers of marine creatures.
这些高级掠食者体内的 In top predators like these,
有毒化学物质可以累积到致命的程度 the toxic chemicals can build up to lethal levels...
它的幼崽有可能是喝了它有毒的乳汁 It's possible her calf may have been poisoned
而中毒死亡的 by her own contaminated milk.
巨头鲸具有发达的大脑 Pilot whales have big brains.
它们无疑会产生不同的情感 They can certainly experience emotions.
从成年鲸鱼的行为来看 Judging from the behaviour of the adults,
失去幼鲸让整个家庭感到悲痛 the loss of the infant has affected the entire family.
流进全球海洋的塑料如不加以遏制 Unless the flow of plastics into the world's oceans is reduced,
那么在未来的几百年内 marine life will be poisoned by them
海洋动物都会受其毒害 for many centuries to come.
生活在蔚蓝大海中的生物 The creatures that live in the big blue
和地球上的其他动物相比或许遥不可及 are perhaps more remote than any animals on the planet.
然而对于免遭人类行为所带来的影响来说 But not remote enough, it seems, to escape the effects
它们还不够遥不可及 of what we are doing to their world.
深入海洋
在浩瀚无垠的远洋中拍摄的最大的挑战是 The biggest challenge of filming in the vastness of the open ocean
找到你拍摄的对象 is to find your subject...
《蓝色星球》摄制组想要拍摄 and the Blue Planet team wanted to film
一个最为非同寻常的题材 one of the most elusive of them all,
极为罕见的"海水沸腾" the rarely witnessed "Boiling Sea".
此前 这种抢食的壮观场面一直颇具传奇色彩 Until now, this feeding frenzy has been the stuff of legends.
汤斯维尔 2014年10月
在澳大利亚东北海岸附近出现了几次可靠的目击后 After some promising sightings off the north-east coast of Australia,
摄制组前去一探究竟 the team heads out to investigate.
我们知道这是种现象 我们知道它存在 We know it's a phenomenon, we know it's out there,
奥尔拉·多尔蒂 制片人
科学家做过记录 the scientists have documented it,
渔民亲口告诉过我们 the fishermen have told us about it,
所以我们知道这是真的 so we know it's happening,
可是还没有哪个人疯狂到 but no-one has been crazy enough
想要去拍摄这个现象 除了我们 to attempt to go out there and actually film it - except for us.
摄制组在160公里外的太平洋水域展开搜寻 The team start their search 100 miles out in the Pacific Ocean.
这种现象之所以被称为"海水沸腾" The reason it's called a "Boiling Sea"
是因为金枪鱼在跃出水面追捕灯笼鱼时 is that the tuna are actually coming out of the water
艾德里安·弗林 海洋生物学家
会使海水翻滚着大量白色浪花 and attacking lanternfish and it creates a lot of white water.
为了拍摄"海水沸腾" To film the Boiling Seas,
摄制组必须首先找一大群诱饵鱼 the team must first find a large shoal of bait fish,
极有可能是夜间升到水面产卵的灯笼鱼 most likely to be lanternfish rising to the surface at night to spawn.
几天过去了 A few days out,
艾德里安认为他可能在声呐上发现了一大群鱼 Adrian thinks he may have spotted a giant shoal on the echo-sounder.
我们现在看到的是一层非常非常密集回声反馈 What we're seeing is a very, very dense layer
大约在水下200米处 at about 200 metres' water depth.
然后 我们探测到这个回声就意味着 And so, the fact that we've got this would suggest
我们找到了一片非常深而密集的鱼群 that we have a very deep and dense layer of fish.
在大海深处拍摄影片的最佳方式之一 One of the best ways to film at such depths in the open ocean
就是使用一台遥控潜水器 is to use an ROV - a remotely operated vehicle
上面载有光敏摄像机 carrying a light-sensitive camera.
但在远海中使用这种重型设备 But working with such heavy equipment in the high seas
是一种很危险的操作 is a risky operation.
设备通讯丢失
幸运的是 技术团队就在身边 Fortunately, a team of technicians is on hand,
24小时过后 他们准备重新下水 and 24 hours later, they're ready to relaunch.
艾德里安把它们投到一片鱼群上方 Adrian drops them on top of
希望那就是他们要找的灯笼鱼群 what he hopes is a large shoal of lanternfish.
好消息是 我们刚把潜水器放下去 Good news is, we've just put the ROV down,
到达了海下250米处 we're down at 250 metres,
这意味着我们已经快下到电缆的尽头了 which means we've gone to almost the end of the cable
没出什么意外 所以一切正常 and nothing's blown up so we're back in business.
但是那里几乎什么都没有 But there's almost nothing there,
只有一层厚厚的浮游生物 just a thick layer of plankton.
在接下来的三周里 Over the next three weeks,
他们没找到一只灯笼鱼 they don't find a single lanternfish.
这趟旅途完美地展示了 This trip is the perfect illustration
为什么我们对海洋知之甚少 of why we know so little about the ocean -
我们寻找一些东西 we came out looking for something,
我们千搜万寻 we've searched and searched and searched,
还是找不到 and we still haven't found it
即使用上任何一种你希望用到的工具 even with every single tool you could wish for.
事后发现 团队拍摄之时 As it turned out, the team had been filming
正赶上厄尔尼诺现象初期 at the very start of El Nino
一个无法预料的气候现象 an unpredictable climatic event
可使海水突然升温 when sea temperatures can suddenly rise
并扰乱鱼类的产卵行为 and disrupt the spawning behaviour of fish.
