大西洋：地球最狂野的海洋（2015）

would go out of their way to avoid.
仅有一种不同寻常的动物从加勒比海
But one remarkable animal swims
all the way from the Caribbean
游到加拿大南部 只为寻找它
to southern Canada in search of it.
在加拿大新斯科舍省附近海域
In the waters,
off the island of Nova Scotia
人们正在寻找这种神秘的海洋猎手
people are on the lookout for
these mysterious ocean predators.
动物学家迈克·詹姆斯和船夫布莱尔·弗里克
Zoologist, Mike James,
and boatman, Blair Fricker
已经致力于研究和保护这些动物长达十六年
have worked to study and protect
these animals for sixteen years.
但要研究它们 首先必须找到它们
But to study them,
they first have to find them.
我们在观察 在看
BLAIR:
We just start watching, just start looking.
有时天气好 能看见一只 之后就再也找不到了
Sometimes, we see one, on a nice day,
and never see him again.
不敢相信它会从你眼前溜走
And you can't believe
that he got away from you.
布莱尔和迈克正在寻找它们中的巨人
Blair and Mike are searching
for a giant of its kind.
但是巨人并不意味着容易找到
But just because it's giant,
doesn't make it easy to find
我刚刚看见它了 在两点钟方向
BLAIR:
I think I just saw him, two o'clock.
就在那里
Right there.
看到我指的地方了吗
-看到了 -就是它
See where I'm pointing?
- Yep. - Definitely him.
准备好你的网
BLAIR:
Yes, get your net ready.
它在那里做了一个漂亮的转身
MIKE:
Oh, she's taking a pretty good turn, there.
它去那里了
There she goes.
问题在于它们不会停下来
BLAIR:
The problem is they're not staying.
它们浮出水面只是为了呼吸 之后就继续寻找
They're just coming up for breath
and really tracking along
水母
a few jellies, eh?
都准备好了吗
MIKE:
All done?
你还能看见它吗
-没有 有一会儿没看见了
RADIO: Did you see anything more?
- MIKE: Nah, it's been a while.
它在那里 就在水下 我想它又要浮上来了
BLAIR: There he is, just under the surface.
Come up again, l think.
最终捕获成功 需要很多技巧和力量
Success at last, but this is an animal
that takes a lot of skill and strength
才能不伤害并捕获这种动物
to bring on board without doing it harm.
先让它的头进去
-等等 等等
BLAIR: We'll get her in headfirst.
- MIKE: Hang on, hang on.
棱皮龟
A leather backed turtle.
重达九百公斤 它们是世界上最大的海龟
At up to nine hundred kilograms in weight,
this is the largest sea turtle in the world.
迈克估算每年来到加拿大海域的海龟超过一千只
Mike estimates that over a thousand
turtles come to Canadian waters every year.
他标记过的海龟超过三百只 如果下次再捉到时就能进行辨认
He's tagged over three hundred,
so they can be identified if they're caught again.
它真的好大
MIKE:
Oh, she's really big.
每只海龟都会被测量
Every turtle gets measured.
148.2厘米
MIKE:
148.2
曾经测量过最长的海龟几乎是这只的两倍
The longest ever recorded
was nearly twice as long as this one.
脖子的周长有一米多
So that's a metre plus around the neck.
相比其他较小的海龟 棱皮海龟有决定性的优势
Leatherbacks have a crucial advantage
over other, smaller sea turtles.
不同于寻常的爬行动物 它们能够产生体热
Unusually for reptiles,
they can generate body heat
巨大的身躯能帮助它们维持体温
which their huge bulk helps them to retain.
这意味着它们能游出温暖的湾流之外
That means they can swim
beyond the warm Gulf Stream
潜入丰饶的北部海域
and deep into the bountiful northern seas.
而且迈克近期揭示了
And Mike has recently revealed
棱皮龟在昏暗的海洋里追逐着什么
what the leatherbacks
get up to in the murky depths.
他在一些龟的背部安放了订制的小型摄像机
He's fitted small cameras
to the backs of some of his turtles.
棱皮龟的视力极佳
Leatherbacks have excellent eyesight
有助于在绿色浮游生物遍布的海洋中追逐狮鬃水母
helping them track down the lion's manes
in the green plankton soup.
但水母几乎就是一团水
But Jellyfish are mostly water.
大型动物需要吃很多水母才能生存
A big animal needs to eat
a lot of them to survive
迈克还发现棱皮龟从早到晚都在进食
and Mike has discovered
that turtles feed from dawn to dusk
整个夏天 棱皮龟每天进食的水母重量
eating nearly three quarters of
their own body weight in jellyfish everyday
相当于自身重量的四分之三
all through the summer.
湾流创造了这片无比富饶的海域 使得这些巨型爬行动物
These giant reptiles thrive here
because of the incredibly fertile seas
在此茁壮成长
that the Gulf Stream has helped to create.
而且这片肥沃的海洋也养育了数量惊人的常见海洋生物
And that fertility also sustains huge numbers
of a more familiar sea creature.
新英格兰和加拿大东部海域有着极为丰富的鱼类资源
The waters off New England
and eastern Canada are incredibly rich in fish
但今天 这些玉筋鱼在错误的时间出现在了错误的地点
but today, these sand eels are in
the wrong place at the wrong time.
昏暗中 一股气泡开始包围鱼群
Out of the murk, a stream of bubbles
begins to surround the shawl.
惊慌失措的鱼群聚集得更加紧密
The panicking fish
gather even tighter together.
鱼群之下 一声比发动机还响亮的嘶鸣刺穿了海水
Beneath the shawl, a scream,
louder than a jet engine, pierces the water
驱赶着上方的鱼群
driving the fish upwards.
座头鲸的叫声
HUMPBACK WHALE CRIES
猎手围绕着鱼群螺旋上升 气泡也随之收紧
The net of bubbles draws tighter
as the predator rises around the fish in a spiral.
这是座头鲸
It's the humpbacks.
经过长达六个月的禁食 它们正在充分利用时机捕猎
After up to six months of fasting,
they're making the most of their chance to feed.
座头鲸的叫声
HUMPBACK WHALE CRlES
座头鲸是唯一一种能把其猎物困在气泡网中的动物
Humpbacks are the only animal
that traps its prey in a bubble net.
鲸鱼的嘴巴里是巨大的条状鲸须
The whales have a mouthful
of giant strips of baleen
材质类似于手指甲
a fingernail like material.
它们把海水和鱼一起大口吞下
They gulp in huge mouthfuls
of seawater and fish
之后迫使海水通过鲸须过滤出来 鱼则困在了嘴里
and force the water back out through
the baleen's sieve, trapping the fish inside.
放眼这一大♥片♥海面 上百头座头鲸正在狼吞虎咽
Across a huge stretch of the ocean,
hundreds of whales gather to gorge themselves.
这里食物极为充足
There is so much to eat here
以致于鲸鱼在夏天获取的脂肪
that the whales can put on
enough fat over the summer months
足以维持一整年的需求
to last them the whole year.
但并非所有从加勒比海出发的座头鲸
But not all of the humpbacks
that set off from the Caribbean
都会在北美洲海岸结束它们的迁徙
end their migration
off the North American coast.
有些鲸鱼会游得更远
Some swim much further
朝向大西洋更为偏远而富饶的海域
heading for even greater riches
on the far side of the Atlantic
那里也是湾流的目的地
where the Gulf Stream is also heading.
美国北部海岸 海风开始向东方吹去
Off the northern coast of America,
the winds begin to blow due east.
推动着湾流跨过大西洋 朝向欧洲
That pushes the Gulf Stream
across the Atlantic towards Europe.
离开美国时 湾流内的水温比其北部海水的温度要高出十摄氏度
As it leaves America, the Gulf Stream is up to
ten degrees warmer than the sea just to the north.
暖流加热着其上方的空气 也造成了气压差
The warm current warms the air above it,
which creates a difference in air pressure
产生了更猛烈的海风
leading to even stronger winds.
这也塑造了北大西洋臭名昭著 波涛汹涌的海域
This helps whip up the notorious
rough seas of the north Atlantic.
除了创造狂暴的天气 湾流也再一次哺育了生命
As well as creating turbulent weather,
the Gulf Stream, once again, drives life.
洋流卷起海底的养分
The flow of the current
churns nutrients up from the sea floor
为北大西洋带来营养 也为海鸟带来了盛宴
and enriches the north Atlantic,
creating a feast for seabirds.
鲣鸟飞行数百英里来此捕鱼
Gannets fly hundred of miles
in their fishing trips.
它们撞击海面的速度高达五十英里每小时
They hit the water at up to fifty miles an hour
为了追逐猎物 它们能下潜到二十米水深
and swim down as much as twenty metres
in pursuit of their prey.
这片富饶的海域能给你丰厚的回报
There are rich rewards to be had
in this fertile ocean
但若出现误判 大西洋的力量足以让你毁灭
but misjudge the conditions out here,
and the Atlantic's power can destroy you.
这条定律适用于所有生物和所有人
And that goes for everything and everyone.
