我们的海洋（2024）

From the West Pacific, they form a mountainous coastline
引导巨大的洋流向北环流
that guides the great current on a loop northwards,
每秒将超过5000吨♥的热带水体
carrying over 50 million tons of tropical water every second
运往日本列岛
towards the islands of Japan...
将目的地周围的水加热到27摄氏度
...where it warms the surrounding water to 80 degrees Fahrenheit.
刚好让世界上最北的热带珊瑚礁 得以生存
Just enough to sustain tropical coral reefs
further north than anywhere else on Earth.
一只年轻的宽腕乌贼
A young broad club cuttlefish...
正在寻觅爱情
is looking for romance.
因为今天标志着 一年一度的乌贼舞会的开始
Because today marks the start of the annual Cuttlefish Ball,
每年春天温水令它们发♥情♥时 舞会就会举♥行♥
held each spring when the warming water helps trigger their urge to find a mate.
乌贼有一种惊人的能力
Cuttlefish have the astonishing ability
能够通过皮肤传达感情
to communicate their feelings through their skin.
但这种超能力也可能是弱点
But this superpower can also be a weakness.
尤其是如果对初次约会有点紧张
Especially if you're a little anxious about your first date.
一只雌性乌贼 吸引了这只雄性乌贼的目光
One particular female has caught his eye.
深呼吸
Deep breath.
开始行动
Here goes.
当雄性乌贼靠近时
As he approaches,
它的大脑 直接与皮肤上的数以千计的像素连接
his brain connects directly with thousands of pixels in his skin,
就像在说
to say,
“你好 我很酷 很冷静 很放松”
"Hi. I'm cool, calm and relaxed."
正合她意
Just what she is looking for.
但是麻烦来了
But here comes trouble.
这些强硬的家伙明确表示出了攻击性
These tough guys are making their aggression clear.
它们的趾高气昂和斑马条纹 表明它们非常愤怒
Their swagger and zebra stripes mean they're angry...
而且不怕展示自己的力量
...and not afraid to throw their weight around.
小伙子遭到了排挤
The young male is cut out.
但它就像绿巨人一样 它们惹错对象了
But like Hulk, they shouldn't make him angry.
它们不会喜欢它生气时的样子
They won't like him when he's angry.
它立刻展示出自己强烈的斑马条纹
Instantly he displays his own intense zebra stripes.
它发脾气了
With his temper unleashed...
吓跑了一个对手
he scares off a rival.
然后它回到雌性乌贼身边
And he returns to the female.
但雌性乌贼对强硬不感兴趣
But she's not interested in a tough guy.
为了赢得芳心 雄性乌贼得保持冷静
To win her over, he'll need to keep his cool.
于是它惊人地展示出
So, in an incredible display,
自己分♥裂♥个性的能力
he appears to split his personality.
用放松的色调 向雌性展示出自己的冷静
With his relaxed tones, he shows the female he's calm,
同时向对手展示 象征男子汉气概的条纹
while showing his rivals his macho stripes.
通过愤怒管理 它的超能力终于转化为优势
At last, with a little anger management, his superpower has become an advantage.
表现出自己既强大又善解人意
Showing he's the strong yet sensitive type.
雌性终于被打动了
And finally, she's impressed.
在乌贼的世界 事态进展飞快
Things move fast in the cuttlefish world.
没多久 它们就开始建立家庭
And in no time, they're starting a family.
雌性将卵产在
She lays their eggs
能被洋流保温并充氧的地方
where they'll be kept warm and oxygenated by the current.
从这里开始 巨大的洋流也改变了性格
From here, the great current also transforms its character,
它经过 标志着火环带北部边界的活火山
becoming rich with minerals as it passes the active volcanoes
变得富含矿物质
that mark the northern boundary of the Ring of Fire.
因此当它 在三年后抵达阿♥拉♥斯加海域时
So that when it arrives off Alaska three years later...
揭开了一场年度盛宴的序幕
...it helps fuel an annual feast.
座头鲸
Humpbacks.
从夏威夷远道而来 期盼着这季节性的盛宴
They've traveled all the way from Hawai'i in anticipation of this seasonal bounty.
但捕鱼现状已不同于往日
But the fishing isn't what it used to be.
因为如今我们的船队通常先到
Because these days, our fishing fleets often get there first.
我们对鱼的偏好
Our appetite for fish means
意味着海洋掠食者必须与我们竞争
that marine predators must compete with us.
但这两个鬼祟的家伙有一个秘密地点
But these two shady characters have a secret spot.
还有一个计划
And a plan...
以智胜人类
to outsmart the humans.
从鲑鱼孵化场偷鱼
By stealing fish...
...from a salmon hatchery.
这些网中有1400万条小鲑鱼
These nets contain 14 million young salmon
即将被释放到野外 以帮助补充野生种群
that will soon be released to help repopulate the wild.
有不限♥量♥自助餐 又何必与捕鱼船队竞争?
Why go up against the fishing fleets when you've got an all-you-can-eat buffet?
但这个渔场固若金汤
But it's a fisheries Fort Knox.
当你身长15米时 就不可能偷偷越过安保
You can't sneak past security when you're 50 feet long.
不像有些小偷
Unlike some petty thieves.
这似乎是一项不可能完成的任务
It seems like an impossible mission.
但这对狡猾的搭档已在此处侦察多年
But this crafty duo have been scoping the joint for years.
它们有一个计划
And they've got a plan...
在孵化场放出小鲑鱼的那一刻出击
to strike the moment the hatchery releases the young salmon.
第一步 把握好时机
Step one, get your timing right
保持低调
and keep a low profile.
貌似没有危险
With the coast seemingly clear,
宝库解锁
the vault is unlocked.
锁链的声音就像晚餐的钟声
The sound of chains is like a dinner bell...
提醒鲸鱼猎物即将到来
alerting the whales that the prize is on the move.
第二步
在小鲑鱼出来之前 就闯入其中
Step two, break in before the young salmon get out.
劫掠开始
It's a smash-and-grab job...
但大多数鱼还是逃脱了 开始向海中散去
...but most of the fish break free and start scattering out to sea.
所以最后一步是吹出一张气泡网
So, the final step is to blow a net of bubbles...
其中隐藏着一种新的觅食技巧
...which conceals a new feeding trick...
用胸鳍将鱼群赶成一个更紧密的球
using their pectoral fins to herd the fish into an even tighter ball.
犯罪大♥师♥的完美抢劫大功告成
These criminal masterminds have pulled off the perfect heist...
但也有足够多的鲑鱼得以逃脱 增加了野生种群的数量
although enough salmon do escape to boost numbers in the wild.
说到底 人类也无能为力
In the end, there's nothing the humans can do...
无法阻止海洋中这些重达40吨♥的盗贼
...to stop the ocean's 40-ton thieves.
寒冷而肥沃的洋流 沿着海岸线向南流动
As it begins to follow the coastline south,
让北美洲火山密布的西海岸 变得富饶肥沃
the cold, fertile current enriches the volcanic west coast of North America...
滋养了巨大的海带森林
supporting forests of giant kelp,
其中有一些从海底长出高达55米
some towering 180 feet above the seabed...
这里的生命多样性令人赞叹
home to an astonishing variety of life.
每一层都有生物栖息
Every level is inhabited.
海狮在枝条间徜徉
Sea lions soar through the branches.
海獭在海带顶部休息
Sea otters rest in the canopy...
并在森林底部觅食
and feed on the forest floor,
这里是无脊椎动物生活的迷人世界
which shelters an enchanting world of invertebrates.
洋流的影响甚至改变海洋之外的生命
The current's influence even transforms life beyond the ocean.
它让延绵数千公里的沿海雨林 得以存活
It sustains thousands of miles of coastal rainforest,
包括地球上最高的树木
including the tallest trees on Earth.
它们只能在这里生长
They can only grow here, where the current chills the air,
洋流将这里的空气冷却
让它们沐浴在海雾之中 并带来柔和的雨水
bathing them in sea mist and delivering soft rain...
帮助整个海岸线保持凉爽
...helping keep this entire coastline cool.
洋流到达洛杉矶时
When the current reaches Los Angeles,
速度变慢
it slows,
在数个平静的夏日里
and on a few calm summer days,
表层温度刚好
the surface layer warms just enough...
为一场壮观的景象作好准备
to set the stage for a great spectacle.
这不可思议的光叫作“生物荧光”
This incredible light is called bioluminescence,
是数以十亿计的微小浮游生物 发出的光芒
the glow of billions of microscopic plankton.
每一个被扰动的浮游生物 都会发出微光
As each one is disturbed, it emits a glimmer.
这正是加州海狮在等待的时刻
And it's what these California sea lions have been waiting for.
当沙丁鱼群捕食浮游生物时
As shoals of sardines feed on the plankton,
它们会发光
they light up...
将自己置身于聚光灯下
turning the spotlight on themselves.
所有这些活动吸引了海豚来参加盛宴
All this activity draws dolphins to the feast.
大自然的烟花 创造出了如此多的光亮
连白天的掠食者也被吸引而来
The natural fireworks create so much light that even daytime predators are drawn in.
谁能想到呢?
Who'd have thought?
自然界最伟大的灯光秀之一
One of nature's greatest light shows,
居然隐藏在众目睽睽之下 就在洛杉矶闪亮的霓虹之外
hiding in plain sight,
just beyond the bright lights of LA.
随着巨大的洋流流向热带地区
As the great current flows toward the tropics,
部分分流进入一个沙漠海域
some diverts into a desert sea.
墨西哥的加利福尼亚湾
Mexico's Gulf of California.
通过不断补充其水源
By constantly replenishing its waters,
洋流帮助保持墨西哥湾的肥沃和凉爽
the current helps keep the Gulf fertile and cool.
这里被称为“世界的水族馆”
It's been called the world's aquarium...
因为极其丰富的鱼类多样性
for the sheer diversity of fish.
但并不是所有鱼 都满足于与群体一起生活
