向深海出发（2008）

It just means nothing's got a chance to evolve or adapt to warmer conditions.
这意味着什么都没有机会适应瞪化的环境
It's just complete... It's wave bye-bye.
完全说拜拜了
Devastation, devastation.
毁灭了
The water temperature along these shores
这些海岸的水温
has risen one and a half degrees in the last 50 years.
在过去50年里升高了15度
The impact on the giant kelp has been enormous.
给巨型海藻带来了巨大的冲击
A one and a half degree rise in water temperature in this region
这个海域的水温升高1.5度
has pretty much caused the decline of 95% of these kelp forests.
导致海藻森林缩水95％
It just seems like such a microscopic change,
看起来是细微的改变
but the point about the kelp ecosystems
但是海藻生态系统的毁灭表明
is that they're such a great example of how a tiny, tiny change
哪怕是一个小小的改变
in such an important parameter, such as temperature,
比如一个重要参数 水温的改变
can have a completely decimating effect.
可以带来完全消灭的效应
The loss of vast areas of Tasmania's kelp forests
塔斯马尼亚岛广大地区的海藻森林的损失
is also threatening the marine life that depends on them.
也威胁到了依赖它的海洋生命
The most vulnerable species are those which are so well adapted to the kelp
最大的受害者就是那些适应海藻环境的生物
they can survive nowhere else.
它们在其它地方是生存不了的
Philippe and Tooni are about to go in search
菲利普和托妮即将开始
of one of the most extraordinary.
研究其中一种最罕见的生物
We are here to dive in water
我们要潜水
which hopefully harbours a quite unique and mysterious animal.
但愿可以发现一种独特而神秘的动物
Yes, it's well camouflaged within their environment,
是的 它善于在环境中伪装
so it's going to be
所以这将会是
a bit of a hunt for a very, very inconspicuous animal,
寻找一种不显眼的生物
but apparently they're incredibly exquisite.
但是 它是那么的优雅
So, it's definitely worth doing.
所以这是值得的
Five, four, three, two, dive, dive, dive!
5 4 3 2 下潜
So, we're looking for something about 50 centimetres long
我们在寻找身长50厘米的动物
that looks exactly like a piece of seaweed.
它看起来就像是一块海藻
I'm having a good look right down underneath everything
我要好好在下边找一找
because the way that they protect themselves from predators
因为它只有在下边待着才能躲避食肉动物猎食
is to get right in amongst the kelp.
它就躲在海藻中间
Any luck, Philippe?
运气好吗 菲利普？
No, so far, I haven't found anything, Toon.
还没有 什么发现都没有
Of course, that's the idea for them anyway.
这就是它们想要的效果
Stay hidden and survive.
躲起来生存
They're doing a damn good job of it, if I do say so.
可以说它们很厉害啊
Apparently you've got to look for the eye movement, Philippe.
你得注意它们的眼部活动
You can just see the little eye movement amongst the kelp fronds.
你可以在海藻叶子里发现细小的眼部活动
These rare animals are so perfectly evolved
这些罕见的动物进化很好
to blend in with the seaweeds
可以融入海藻里
that spotting one is incredibly difficult.
想看到一只都很难
Just keep looking.
继续找
I got one, I found one! I found one, I found one!
我找到一只了咙到了
Oh, my God, it's beautiful!
天啊 真漂亮
Tooni, I've got a sea dragon over here. Come and look at this.
托妮 这里有一只海龙陈看啊
Found only in the kelp forests of South Australia and Tasmania,
它只有在澳洲南部的塔斯马尼亚岛的海藻森林里能找到
this is the weedy sea dragon.
这就是海龙
So brilliant!
太棒了
The blue and green and red!
又蓝又绿又红的
They're related to the sea horses,
它们是海马的近亲
but they're a slightly different species.
但是二者又有点区别
And how effortlessly they swim through this,
它们可以毫不费劲在海藻里游动
as we're getting tossed around like we're in a washing machine.
而我们就像是在洗衣机里搅拌一样
You see its fins all moving.
它的蟹在运动
It just looks as though nothing is actually propelling it at all.
它的蟹在运动
Very, very fine fin on its tail there.
尾巴上的蟹很厉害啊
You can see why it's such a perfect camouflage,
你可以看出它是多么善于伪装
and they've evolved just to look exactly like the kelp that they live in.
它进化得就像是它所生活的海藻一样
And it protects them from predators
这样就可以保护他们不受食肉动物的猎食
cause they're not particularly fast swimmers.
因为它本身不是游泳健将
It will not only use its camouflage for evading predators,
它们不仅利用伪装来躲避食肉动物的猎食
but also for sneaking up on its prey,
还可以利用来悄悄接近它的猎物
small little crustaceans and zooplankton.
也就是细小的甲壳类动物和浮游生物
Things in and amongst and around the kelp floating in the water column.
还有那些在随着海藻在水流里漂浮的东西
To help them catch prey,
为了捕捉猎物
sea dragons have eyes that can move independently.
海龙的双眼可以独♥立♥转动
While one eye looks forwards, the other can look backwards.
只看前方 一只看后方
This is a very rare sighting.
这是非常罕见的发现
Like their cousins, the sea horses,
和它们的近亲海马一样
weedy sea dragons are under threat.
海龙也处在威胁中
It's just so sad, isn't it?
太伤心了
With the decline of the Tasmanian kelp forests,
随着塔斯马尼亚岛的海藻森林的缩水
that actually means that the habitat for these beautiful creatures
这些美丽的生物的栖息地
is getting smaller and smaller.
越来越小
The thing is, with something so perfectly adapted
问题是 对这么适应
to one particular ecosystem,
某种特定的生态系统的生物来说
it's got nowhere else to go.
它无路可走
I think it's time to let her go on her way.
该让它走了
Wow, what a gift!
真是恩赐啊
For their next task,
他们下一个任务
the team is going in search of evidence of the most fundamental change
就是寻找南海所经历的最根本的改变的证据
the Southern Ocean has ever experienced, its creation.
那就是它的结晶
That evidence lies within some of the highest sea cliffs in the world.
那个证据存在于世界上最高的海崖之内
These towering columns of basalt rise 300 metres out of the ocean.
这些是海拔高达300米的玄武岩
They are riddled with a vast network of underwater caves,
它们充满了无数的水下种秘洞穴
carved out over millions of years by the Southern Ocean's pounding seas.
这些洞穴是经过南海几百万年的冲刷而成
Those same seas make diving here perilous.
这使得在这里潜水尤为危险
The problem is with this big sea rolling
问题在于大浪的翻卷
it's going to be booming up in those caves
海水涌入洞穴中
and I've been hung up in sea caves before,
我以前进过海洞
and you just can't be messing around in them.
千万不能在那里乱来
Hold it there, Pete!
停下 皮特
Rather than put the rest of the team at risk,
为了不让其他队员冒险
Paul decides to check them out first.
保罗决定首先查看海洞
Okay, Paul.
好 保罗
He's been diving for 40 years
他已经潜水40年
and has made over 6,000 dives.
次数多达6000次
Wow! There's a lot of water moving round here, boys.
这里真是暗湖汹涌啊
It's very, very hard to keep in position. Just look at that.
难以固定位置 看啊
Blimey! Hanging on to the weed.
哎呀 抓住海藻
The Southern Ocean has got me in some kind of mad,
南海让我陷入疯狂的境地
industrial wash cycle at the moment!
就好像洗衣机在翻滚一样
There's no way I can get in that cave right now.
现在无法进洞
The team has been thwarted by the power of the Southern Ocean.
探险队被南海的力量所阻挠
There's just no way. You get near it and it's just...
无法靠近 你离它很近 但…
Really got to try and work to come back here.
回来的时候很费劲
You know, watch the waves, watch the weather, dive it at night,
看好洞穴 看好天气 晚上潜水
dive it at 3:00 in the morning. Do whatever we can.
凌晨三点潜水尽力而为
We've got to come back and dive it.
我们得回来下潜
There's now an anxious wait for tomorrow's weather forecast.
现在我们都在焦虑地等待明天的天气预报
Tooni will be diving with Paul. They've both trained as cave divers.
托妮将和保罗一起潜水他们都训练过潜入洞穴
A five will develop to the southwest of Tasmania today.
今天 塔斯马尼亚岛西南会有五级风浪
A weak, cold front is passing to the south...
股弱冷筐湖正在穿过南部
The forecast is better
预报更好点
but Paul is still concerned about the dangers of this cave dive.
但是保罗还是担心潜入洞穴的危险
All I can think about is Tooni and me
我只能想到的就是托妮和我
getting shoved up into a narrow groove by the force of the Southern Ocean.
被南海的力量冲进狭窄的手套里
Explain to me what the potential issues are.
给我解释一下潜在的危险
What we're learning from the locals is that the surges come in
我们从当地人那里得知大浪冲进来
and then they call it... Every once in a while they get a king swell
他们管它叫爆湖
which is a great big one, and pushes... Then it can push us up
它可以把我们顶出水面
and what I'm worried about is being up in the foam
我担心的就是被顶到泡沫上
and I think we can get stuck and trapped on the surface in there.
我想我们会被困在水面上
Well then, don't go!
那就别去了
Well, I think time is so short that no matter what the conditions,
时间很短暂 不管发生什么情况
almost no matter what the conditions,
不管什么情况都好
you and me need to get in and have a sniff of them,
你和我都要摸进去看一下洞穴
cause if we can pull it off, it'll be blooming great.
如果我们能进去的话里边会是别有洞天
And even if we can't pull it off, we'll get an idea what it's all about.
就算我们进不去我们也能想出来里边是什么样的
