向深海出发（2008）

No, no. Nor I.
我也没有
To find out what's causing the sudden rise in temperature,
为了探究温度为什么会突然升高
they descend even further.
他们继续下潜
Oh, my goodness, it's purple. This is bizarre.
我的天哪 是紫色的 真是奇怪
That is psychedelically purple.
那是引起幻觉的紫色
It's like being in an outer space chemical soup.
就像是到了外太空的 化学物混杂的汤里一样
As a marine biologist,
作为一个海洋考古学家
Tooni recognises what the purple cloud must be.
托尼知道紫色意味着什么
We're right in the middle of a layer of purple sulphur bacteria.
我们到了紫色硫细菌中♥央♥
They contain a pigment which they use to trap sunlight,
它们有吸收阳光的色素
and that pigment is purple.
色素是紫色的
The bacteria absorb the sunlight's energy to photosynthesise,
它们吸收太阳光的能量 进行光合作用
but not all the energy is absorbed.
但是不是吸收所有的光能
And the reason it's warm is because, purple sulphur bacterium,
温度升高的原因 可能就是这些紫色的硫细菌
they're not particularly good for trapping that sunlight.
它们吸收光并不是很充分
So about 70% of the energy of the sun is just dissipated as heat.
有70%的能量都是浪费掉了的 以热的形式释放出来
Bacteria like these were one of the few life forms that could survive
这些细菌是很少在早期的大海中
in our early seas.
能存活的生物群
But when they photosynthesise,
但是当它们进行光合作用的时候
some produce a poisonous by-product, hydrogen sulphide.
有些可以释放副产品硫化氢
In high concentrations, that's as deadly as cyanide.
浓度很高的时候 它们和氰化物一样致命
Oh, God, I can smell it in my face mask.
天哪 我隔着面罩都闻到了
Oh, it really smells!
真的闻到了
None of their face is exposed to the water.
他们的脸没有接触到海水
What's happening is that their skin is actually absorbing the hydrogen sulphide
这样是因为他们的皮肤 吸收了硫化氢
and that's moving its way and circulating through their body
还随着血液循环到达鼻窦
into their sinuses, and that's how they're smelling it.
这就是为什么他们闻到的原因
To discover more about conditions in our early oceans,
为了探究更多有关早期海洋的情况
Paul and Tooni need to find out what's below this toxic layer.
托尼和保罗需要探明 有毒物质层下面是什么
It can't possibly get any worse.
情况已经相当不好了
Let's go down another half a metre or so.
我们再下去大概半米吧
Oh, man, it's absolutely pitch black.
哦 伙计 实在够黑
It's like somebody's just sucked all the light away.
好像什么东西一下把光全都吸收了
And the bacteria just above us have actually sucked all the light out,
我们上面的细菌群把光全部吸收了
so no sunlight energy reaches this layer.
所以没有光线到达下面
This is why the black hole appears so dark from the surface.
这就是为什么 从上面看有黑洞那么黑原因了
Then Lucy discovers something else.
露西也发现了点什么
The oxygen levels have gone from 7.8 at the surface, all the way down to .18.
氧含量从海面的7.8 一路下降到了0.18
Wow! I know that's...
哇 我知道 那是…
Paul, Tooni, surface. We're also noticing on the probes
保罗 托 我们一直盯着探测器
that the oxygen level has dropped considerably.
氧含量已经降了很多了
There's almost no oxygen in the water here.
那儿水里几乎没有氧气了
The layer of bacteria acts as a barrier, preventing the sunlight
那些细菌群好像 就是一个屏障阻止了光线
and oxygenated water above from getting down here.
和上面充满氧气的海水 下到这里来
These are the conditions they have been looking for.
这就是他们要寻找的情况
What Paul and I are swimming through,
我和保罗游过的地方
is what the oceans would have once been like, dark and gloomy,
就是早期海洋曾经的样子 又黑又暗
very, very little oxygen and just very lifeless by the looks of things.
没有氧气 也没有生命的迹象
With its high concentration of sulphur bacteria and no light or oxygen,
在浓密的细菌群下面没有光线 也没有氧气
this body of water is as close as we can now get to our ancient oceans.
这里已经是最像古代海洋的了
We are three and a half billion years back in time.
我们回到了3500万年前
The oceans formed when the Earth was about 200 million years old.
大海大概是在地球出现 两亿年后形成的
They were a series of hot oxygen-free pools
是一系列都是热的 不含氧的大池子
with very little life, dotted across the barren volcanic landscape.
鲜有生命 散布在荒凉的火山之间
They remained that way for over a billion years.
这样的情况持续了大概十亿年
I'm getting sort of weird sensations on my skin.
我的皮肤有种奇怪的感觉
It's really, really tingling.
真的有麻痒的感觉
After just 20 minutes, their bodies have started to react
20分钟后 他们的身体就有反应了
to this harsh environment.
这是因为恶劣的环境
It's having some weird effect on our skin.
我们的皮肤有了反应
I can almost feel my hair burning.
我感觉我的头发都在燃烧
I need to get this suit off, 'cause I am itching in here.

Dive safety supervisor Richard Bull has heard enough.
潜水安全监察员 理查德·布尔听不下去了
It's time to get them out.
是时候接他们上来了
Tooni, surface.
托尼 上来
There's too much that we don't know about down there.
下面还有很多我们不知道的事
We don't know how the gas affects them,
我们不知道那些气体 是怎么影响到他们的
we don't know how it affects the equipment.

有太多不确定
We're coming up.
我们上来了
How was it?

在你下去的过程中 是吗?
To the point of it being oddly, unhealthily warm.
下去之后 就奇怪的热 不舒服
Ooh, look at that!
哦 你看那
That's where the metal's been oxidised by the bacteria.
那就是细菌氧化金属的地方
This is a brass clip and this is a brass-bodied pressure gauge.
这是黄铜片 这是黄铜压力阀
I've just noticed they've both gone off.
我看到它们分解了
But it's no surprise to see some other manifestation
但是看到这些现象也没什么奇怪的
of that chemical reaction down there, 'cause it's pretty powerful.
因为那些化学反应在下面很强
That's how our oceans were, not these wonderful live masses
这就是大海从前的样子 不是现在覆盖地球表面70%
of water covering 70% of our surface.
的生机勃勃的水体
They were like that weird place. That's where we started.
就像那个奇怪的地方 我们生命就从那样条件下开始的
And so it's fantastic to be in a bit of water
有机会能进入到
that is exactly the same as our oceans were three and a half billion years ago.
跟3500万年前一样的大海真好
I mean, you know, top that.
我的意思是这再好不过了
