向深海出发（2008）

which you'd expect to see on most cetaceans, or certainly dolphins.
别的很多都有的 即使是海豚也有
We think they've evolved to not have them for one of two reasons.
我想这还有一两个原因的
When they're under the ice, it's much easier to swim along the ice
当他们在冰川传川底下的时候 很容易在冰川下面运动
without a dorsal fin sticking out.
不会受到背绪的干扰
The other reason is that if they can reduce the surface area
另外一个原因就是 要是他们浮到海面上来
that's out in the water that's not insulated,
不会被人发现
so that they stay warmer without having a whole area
所以他们可以生活在 很大的区域中
where there's blood flowing through that can cool.
只要有食物的地方就 有他们的身影
NARRATOR:This pod of belugas is all adults.
那些白鲸都是成年鲸
They don't turn completely white until they're at least seven years old.
他们要到7岁的时候才会变白
Around 40% of their body weight is blubber,
他们身体40%都是鲸脂油
one of the reasons they were attractive to the whalers.
这也是捕鲸者捕他们的原因
I've never seen belugas in the wild before.
我以前没有在野外看到过白鲸
That was brilliant. Beautiful, they were really...
太聪明了 -漂亮 他们真的…
That was brilliant, so I say mission accomplished.
太聪明了 所以我说任务完成了
The best thing was to see so many of them.
看到这么多真是太好了
Yeah. To see that they were so healthy.
是啊- 看到他们如此的健康
Dozens of them. Yeah.
很多呢
NARRATOR:While this pod might look healthy,
这些看起来都还很健康
the beluga whale could face a new threat.
白鲸遇到了新的威胁
A warming Arctic could speed up the retreat of the glaciers,
北极气温的升高会加快冰川的融化
damaging their feeding grounds.
会破坏他们的生活环境
PHILIPPE:As soon as that glacier recedes far enough that it's on land,
一旦陆地上的冰川融化了
it's not going to be the kind of habitat the belugas need.
那白鲸的生活就会受到威胁
NARRATOR:Increasingly, this is one of the most
慢慢地 这是…
challenging places on Earth to survive.
地球上生活最有挑战性的地方
The Arctic Ocean is extremely cold, not very nutrient rich,
北冰洋真的很冷也不是很富有
and for four months of the year it's in darkness.
一年有四个月都不见阳光
So there's a limit to the marine life that can exist here.
所以海洋生活是受到限制的
But are there corners of this ocean that can beat the odds?
但是这个海洋角落有 什么奇怪的地方吗？
Philippe wants to head south to the shallow waters of Isfjorden.
菲利普想继续南行 想去胁意思佐丹水域
Here, icy Arctic water mixes with water from the Gulf Stream,
在这儿北冰洋的水 跟来自墨西哥湾的水相混合
which began life thousands of miles south
墨西哥湾有生命 在南方数千公里的地方
in the tropical Gulf of Mexico.
就是在墨西哥湾
PHILIPPE:It's kind of a crossroads here.
这是一个交叉路口
This is really the entrance, the beginning of the Arctic habitat,
这是真正的入口 也是北极生物的起源地
and I'm very curious to see kind of what the whole thing looks like,
我小心的看着一切
the whole environment looks like.
整个环境看起来…
NARRATOR:At first, it's not promising.
起先 并没有什么希望
PHILIPPE:It's still pretty barren and white, almost like the surface.
就像表明上看到的那样 一片白色
NARRATOR:But the empty seascape does show how this fjord was created.
但是这让我们知道峡湾 是怎么形成的了
LUCY:You can see the scarring,
你可以看到断崖
where the glacier's sort of moved through the valley.
也就是冰川断裂的地方
NARRATOR:Deep gouges on the ocean floor reveal how millions of tons of ice
那儿有数吨♥重的冰川
scraped across it, scoring the rock
像川石一样分开了
and shaping the fjord.
看起来像峡湾
Then the bleak seascape is transformed.
然后就形成了这样的海湾
LUCY:Look at all this life.
看着这些生命
PHILIPPE:Yeah.
是啊
PHILIPPE:You know, this conception that the Arctic
你知道 这就是北极
is this empty, desolate place,
就是这个荒凉的地方
totally blown away by what we're seeing here.
我们被我们看到的一切震撼了
There's an explosion of life. There's reds and greens.
这是生命的大爆发 到处都花花绿绿
That's a soft coral, related to the kinds of corals that we've seen
那是软珊瑚跟我们 以前起看到的差不多
down in much warmer waters.
在那些温暖的海水里
But this is a soft coral, so it's purely a filter feeder,
但是这些是软的 所以这是滤食动物的粮食
a bright, brilliant pinkish red colour.
这是一种略带桃色的红色
I did not expect to see a soft coral this vibrant here in the Arctic.
我没有想到会看到软珊瑚
NARRATOR:Almost no warm water corals can survive through the winter darkness.
几乎没有珊瑚可以 度过北极的黑暗冬天
They rely on algae that live by photosynthesis and need the sun.
他们是需要光合作用的 他们需要阳光
But these soft corals have no algae.
但是这些软珊瑚没有色素
They just need a steady supply of nutrients.
他们只需要有营养就好
PHILIPPE:It really is like a soup down here.
看起来就想汤一样
This is basically the confluence of the North Atlantic Drift
这就是北冰洋的漂浮物
heading towards the Arctic waters and this is where the two meet,
我们继续向这北极行进 向这两水相遇的地方行进
so that's why it's so incredibly nutrient-rich.
这也是为什么这儿这么富有的原因
It's a very unique environment in many ways.
在很多方便这都是 很独一无二的环境
NARRATOR:The current doesn't just support the coral.
洋流是不支持珊瑚的
It also helps feed these anemones
也可以养育银莲花属植物
by bringing prey within reach of their tentacles.
通过他们的触须
There's even a kelp garden here,
这儿甚至还有花♥园♥
something usually associated with warmer water.
这都跟这温暖的海水有关系
PHILIPPE:If you look closely, I can't see one right now,
要是你仔细看的话 我现在就可以看到一个
but you'll also find Arctic kelp up here.
你还可以找到北极海草
It can photosynthesise, take energy from the sun
他可以进行光合作用 从太阳那儿吸收能量
for just one week a year.
每年有一个星期的时间
It stores up that energy, lasts it for 51 weeks a year.
他们会储存能量 可以用来维持51个星期
That's pretty incredible.
真的是难以想象
NARRATOR:Other types of kelp have begun to thrive here
其他类型的海草也有
in the last few years as the ice has receded,
随着冰川川的融化近年也出现了
allowing more sunlight to reach these shallows.
有更多的阳光照射这个地方
It demonstrates how life adapts to inhabit the most unlikely places.
这就让更多的生物 出现在了这个地方
It gives you another kind of dimension
这是另外一种因素
of just how rich the environment here,
为什么这儿的环境很富有
how much richer than even I thought it would have been.
比我想象得还要富有
When I first came here, I had no idea how much life there is.
当我第一次来这儿的 我都没有想过这儿会有生物
And that just confirms it. I mean, that...
但是当我们确认我是说 你知道…
That was really amazing.
真的令人惊奇
NARRATOR:The warm current flowing from the Gulf Stream
暖流从海湾流过来
also keeps much of the water around western Svalbard ice-free in summer.
也有很多都是 斯瓦尔巴特群岛[挪威]的冰川 融化后的海水
It's home to another Arctic species almost hunted to extinction.
还有一种北极生物频临灭绝
We're just going to look and see what we can see.
我们去看看我们会看到什么
Can you make any out?
你知道吗？
They're quite a way off at the moment, but I can see movement.
他们现在忙但是我现在可以来看
NARRATOR:They've spotted Atlantic walruses.
他们在看大西洋的海象
They were killed for their fat and tusks
他们杀了他为了他的脂肪和象牙
until there were only about 1 00 left here.
海象只有100多头
That was 60 years ago.
那是60年以前
The team wants to see how the walrus population is doing now.
探险队想看看海象现在有多少
Walruses only live in the Arctic region,
海象只生活在北极地区
so for marine biologist Tooni, it's a rare opportunity to get close to them.
所以托妮是很少有机会 遇见他们的
I've just been watching them all tumbling in the water.
我一直在海水中寻找他们
Sometimes the play looks quite frantic,
有时候看起来真的很奇怪
as they are literally rolling and falling over each other.
当他们彼此玩耍的时候
One of them lands on you, and that's it. Curtains.
你会偶尔看到一个
NARRATOR:They can weigh up to two tons, giving them immense power.
他们体重可达两吨♥
Look how far they can push themselves out of the water, though.
他们力量很大 你看他们可以跳多远
NARRATOR:Now that summer has cleared the ice here,
既然阳光把这儿的冰川融化了
the walruses have come to feed.
海象就有东西吃了
They like to feed in about 50 metres of water,
他们生活在海下50米的地方
and they're gatherers, not hunters, and they're after these clams,
他们是群居生活 他们在追逐这些河蚌
which are about that big.
有那么大
NARRATOR:The feeding season in the Arctic is short,
北极的捕食季节是很短暂的
so walruses are binge eaters.
所以海象这时就会大吃几顿
They can consume more than 50 kilograms of clams in just one day.
他们一天可以消化 超过50公斤的河蚌
Paul and Tooni move onto the land to get a closer look.
托妮和保罗到陆地上 去近距离的观看他们
They want to observe the walruses and determine the size of the colony.
他们想去看看这个群体
PAUL:Getting close.
近了
NARRATOR:Walruses are suspicious by nature and easily alarmed,
海象天生就很警觉
so Tooni and Paul approach downwind
所以托妮和保罗必须顺风前往
and crouch to avoid looking like predators.
要匍匐前进不要看 起来像食肉动物
PAUL:All right, there's one, look, on the rim.
好了 那儿有一个你看
Oh, yeah, he's coming up.
对 上来了
But he's not facing us, so let's keep going while he's busy.
但是没有面对我们 所以等他忙碌的时候我们再走近点
Something smells good now. They don't smell good.
什么东西闻起来真不错 他们闻起来不好
But this wind is perfect for us, though.
但是有了风 就好多了
I don't believe they can smell us, Tooni.
我想他们闻不到我们 托妮
We should, uh...
我们应该 恩…
Their Latin name translates as ''tooth-walking seahorse'',
他们的拉丁名字翻译过来 就是“用牙齿走路的海马”
which I just think is such a perfect literal translation.
我想这是一种不错的翻译
