You know, I had a real rough time in school with ADD, and I have a PhD. I earned a PhD, but ... tough to pay attention -- biology, geology, physics, chemistry -- really tough for me. Only one thing grabbed my attention, and it's that planet called Earth. But in this picture here, you'll see that Earth is mostly water. That's the Pacific. Seventy percent of Earth is covered with water. You can say, "Hey, I know Earth. I live here." You don't know Earth. You don't know this planet, because most of it's covered with that -- average depth, two miles. And when you go outside and look up at the Empire State Building, Chrysler Building, the average depth of the ocean is 15 of those on top of one another. We've explored about five percent of what's in that water. "Explored," meaning, for the first time, go peek and see what's there. So what I want to do today is show you some things about this planet, about the oceans. I want to take you from shallow water down to the deep water, and hopefully, like me, you'll see some things that get you hooked on exploring planet Earth. You know things like corals; you've seen plenty of corals, those of you who've been to the beach, snorkeling, know corals are an amazing place to go -- full of life, some big animals, small animals, some nice, some dangerous, sharks, whales, all that stuff. They need to be protected from humanity. They're great places. But what you probably don't know is in the very deep part of the ocean, we have volcanic eruptions. Most volcanoes on Earth are at the bottom of the sea -- more than 80 percent. And we actually have fire, fire deep inside the ocean, going on right now. All over the world -- in the Pacific, the Atlantic, the Indian Ocean. In this place, the ocean floor, the rocks actually turn to liquid. So you actually have waves on the ocean floor. You'd say nothing could live there, but when we look in detail, even there, in the deepest, darkest places on Earth, we find life, which tells us that life really wants to happen. So, pretty amazing stuff. Every time we go to the bottom of the sea, we explore with our submarines, with our robots, we see something that's usually surprising, sometimes it's startling and sometimes revolutionary. You see that puddle of water sitting there. And all around the water there's a little cliff, there's a little white sandy beach. We'll get closer, you'll see the beach a little bit better, some of the waves in that water, down there. The thing that's special about this water is that it's at the bottom of the Gulf of Mexico. So you're sitting inside a submarine, looking out the window at a little pond of water beneath the sea. We see ponds, we see lakes, we see rivers -- in fact, right here is a river at the bottom of the ocean going from the lower left to the upper right. Water is actually flowing through there. This totally blew our minds. How can you have this at the bottom? You're in the ocean looking at more water. And there's animals that only live in that water. So, the bottom of the ocean -- I love this map, because it shows in the middle of the ocean, there's a mountain range. It's the greatest mountain range on Earth, called the mid-ocean ridge -- 50,000 miles long, and we've hardly had a peek at it. Hardly had a peek at it. We find valleys, many thousands of valleys, larger, wider, deeper than the Grand Canyon. We find, as I said, underwater lakes, rivers, waterfalls. The largest waterfall on the planet is actually under the ocean, up near Iceland. All that stuff is in that five percent that we've explored. So the deal about the ocean is that to explore it, you've got to have technology. Not only technology, but it's not just Dave Gallo or one person exploring, it's a team of people. You've got to have the talent, the team. You've got to have the technology. In this case, it's our ship, Atlantis, and the submarine, Alvin. Inside that submarine -- this is an Alvin launch -- there's three people. They're being wheeled out onto deck. There's 47 other people, the teamwork on that ship, making sure that these people are okay. Everybody in that submarine is thinking one thing right now: Should I have gone to the bathroom one more time? Because you're in there for 10 hours -- 10 hours in that little sphere. Three of you together and nobody is going to be around you. You go into the water and once you hit the water, it's amazing. There's a lovely color blue that penetrates right inside you. You don't hear the surface ship anymore, you hear that pinging of a sonar. If you've got an iPhone you've got sonar on there -- it's that same pinging that goes down to the bottom and comes back up. Divers check out the sub to make sure the outside is okay, and then they say "Go," and down you go to the bottom of the ocean and it's an amazing trip. So for two and a half hours, you sink down to the bottom. And two hours of it is totally pitch black. We thought that nothing could live inside that world at the bottom of the ocean. And when we look, we find some amazing things. All the way down -- we call it the mid-water -- from the top of the ocean down to the bottom, we find life. Whenever we stop and look, we find life. I'm going to show you some jellies. They're absolutely some of the coolest creatures on Earth. Look at that thing, just flailing his arms around. That's like a little lobster. That one is like all these animals with their mouths hooked together, the colonial animals. Some animals are tiny, some can be longer than this stage. Just amazing animals. And you can't collect them with a net -- we have to go with our cameras and take a look at them. So every time we go, new species of life. The ocean is full of life. And yet the deepest part of the ocean -- when we go to that mountain range, we find hot springs. Now we were sure -- because this is poisonous water, because it's so deep it would crush the Titanic the same way you crush an empty cup in your hand -- we were sure there would be no life there at all. Instead, we find more life and diversity and density than in the tropical rainforest. So, in one instance, in one peek out the window of the sub, we discover something that revolutionizes the way we think about life on Earth; and that is, you don't always have to have sunlight to get life going. There's big animals down there too, some that look familiar. That guy's called Dumbo. I love him. Dumbo's great. This guy -- oh man, I wish I had more footage of this. We're trying to get an expedition together to go look at this and maybe in a year we'll have that. Go online and look. Vampyroteuthis infernalis. The vampire squid. Incredibly cool. In the darkness of the deep sea, he's got glowing tentacles, so if I'm coming at you like him, I put my arms out in the darkness so all you see are little glowing things over here. Meanwhile, I'm coming at you. When he wants to escape, he's got these glowing pods on his butt that look like eyes. Glowing eyes on his butt. How cool is that? Just an amazing animal. (Laughter) "Vampire" squid, because when it gets protective, it pulls this black cape over its whole body, and curls up into a ball. Outrageous animal. This ship, "The Ship of Dreams" -- a hundred years ago this coming April, this ship was supposed to show up in New York. It's the Titanic. I co-led an expedition out there last year. We are learning so much about that ship. The Titanic is an interesting place for biology, because animals are moving in to live on the Titanic. Microbes are actually eating the hull of the Titanic. That's where Jack was king of the world there on the bow of the Titanic. So we're doing real good. And what's exciting to me is that we're making a virtual Titanic, so you can sit there at home with your joystick and your headset on, and you can actually explore the Titanic for yourself. That's what we want to do, make these virtual worlds, so it's not Dave Gallo or someone else exploring the world; it's you. You explore it for yourself. So here's the bottom line: The oceans are unexplored and I can't begin to tell you how important that is, because they're important to us. Seven billion people live on this planet and all of us are impacted by the sea, because the oceans control the air you breathe, the water you drink, the food you eat. All those are controlled in some way by the ocean, and this is a thing that we haven't even explored -- five percent. The thing I want to leave you with is, in that five percent, I showed you some cool stuff. There's a lot more cool stuff -- every dive we go on in the ocean, we find something new about the sea. So what's in that other 95 percent? Did we get the exciting stuff or is there more out there? And I'm here to tell you that the ocean is full of surprises. There's a quote I love by Marcel Proust: "The true voyage of exploration is not so much in seeking new landscapes," which we do, "but in having new eyes." And so I hope today, by showing you some of this, it's given you some new eyes about this planet, and for the first time, I want you to think about it differently. Thank you very much. Thank you.

你知道嗎,因為我是過動兒,求學過程真是受盡苦頭 但我還是拿到了博士學位 雖然我拿到博士,但是要我專心讀那些 生物、地質、物理、化學 -- 還真的很難 只有一件事抓住了我的注意力 就是這個叫做地球的行星 但是在這張照片裡你看到的 地球大部份是水 -- 那是太平洋 地球的百分之七十都被水覆蓋。你可以宣稱 「嘿!我知道地球啊!我就住在這裡。」 但你真的不了解地球 你不了解這個星球,因為它大部分都被那個蓋住了 -- 平均深度是二哩 你到外面抬頭看看 像帝國大廈,克萊斯勒大樓這樣的建築物 海洋的平均深度是15座這樣的 建築物加起來這麼深 我們已經探索水裡大約百分之五的東西 「探索」的意思也不過就是初步地看看那裡到底有什麼 所以我今天要做的是,我想讓你們看看 一些關於這個星球,關於海洋的東西 我想要帶著你從淺水到深海 希望你能像我一樣,看見一些東西 讓你迷上探索地球 你們都知道珊瑚吧,你們都看過很多的珊瑚 那些去過海邊浮潛的人 都知道珊瑚區是很了不起的地方 那裡充滿了生命,有大的動物,小的動物,有些很安全 有些很危險,鯊魚、鯨魚那些東西 應該把牠們列為保護區,不讓人靠近 這些是很棒的地方,但是你可能不知道 在深海,在非常深的海洋底下 我們有火山爆發 地球絕大部分的火山都在海底 超過百分之八十 -- 那裡真的有火 在海洋深處現在就有火在燃燒 在全世界,在太平洋、大西洋和印度洋 在這個地方,海底的石頭變成液狀 所以海底其實是有波浪 你可能會認為生物不能在那裡存活,但是當我們細看 即使在那裡,即使在地球最深最暗的地方,我們仍然發現生命 這告訴我們,地球的生命力真的很強 所以,真是挺神奇的 每次我們去海底 我們都乘坐潛水艇探險,並使用機器人 通常我們都會看見一些出乎意料的東西 有時候很嚇人,有時候很顛覆傳統思維 你看看那個水坑 有個小懸崖環繞著水坑 還有個小白沙灘 我們靠近點看,你可以更清楚地看見那個海灘 水裡有波浪,就在下面 這灘水的特別之處在於 這裡是在墨西哥灣底 所以你其實是坐在潛水艇裡往窗外看著 這個在海洋深處的小池塘 你知道嗎?我們不但看過池塘,還看過湖泊,看過河流 事實上就在這裡,這裡就是一條海底的河流 從左下方流到右上方 真的有水流經那裡 這完全出乎意料之外:海底怎麼會有這個? 你在海洋中看著更多的「水」 還有那些只能存活在那種水裡的動物 所以在海底 -- 我很愛這張地圖,因為它畫出在海洋中間有一座山脈 那座山脈是地球上最大的山脈 叫做中洋脊 -- 綿延五萬哩長,而我們從未好好看過它 從未好好看過它 我們發現了山谷,成千上萬的山谷 比大峽谷還長、還寬、還深 我們還發現我之前說過的海底湖泊、河流及瀑布 全球最大的瀑布 其實是坐落在靠近冰島的海洋底下 這些東西就是那已探索的百分之五 那麼關於海洋的 探索關鍵在於你必須要有科技配合 光有科技還不夠,光靠我大衛蓋羅 或類似的單人探險也不夠。這需要一個團隊 你一定要有人才。你一定要有一個團隊 你也得要有科技配合,這裡我指的是我們的船亞特蘭提斯號 及這個潛水艇阿爾文號 那麼在這個潛水艇裡面 -- 這是阿爾文號下水情況 -- 有一個三人團隊。他們正被推到甲板上 另外還有一個47人的團隊在船上工作 確保這三人團隊一切安好 在潛水艇上的每一個人現在都在想同一件事: 我應該再上一次廁所嗎? 因為你要在那裡面待十小時 -- 十小時都在那個小空間裡 只有這三人在一起,沒有別人在你身邊了 你進到海裡,你一但碰到水,那真是不可思議 這漂亮的藍色沈浸入你的身體 你再也聽不到海面上的船聲音 你只聽見聲納的脈衝信號 如果你有一只iPhone,你也會產生這種聲納 -- 與那個往下打到海底再反射回來的脈衝信號是一樣的 潛水員會檢查潛水艇四周以確保安全 然後他們會說「下水」 下水後你會一路潛到海底,這過程令人嘆為觀止 所以你以兩個半小時的時間潛沈到海底 其中有兩個小時是漆黑的 我們都以為沒有東西可以在 海底世界存活 但當我們去看的時候,我們發現很奇妙的東西 一路向下潛 -- 我們稱從海面到海底間的水 為「中層水」 -- 我們都發現生物存在 無論我們停在哪,都會發現生物 我要給大家看看一些水母的畫面,因為 牠們真的是世界上最酷的生物之一 看看那隻在揮舞牠的觸器 那真像一隻小龍蝦 那隻很像有好幾隻動物用嘴接在一起 牠們是群居的動物 有些動物很小,有些則比這個講台還長 真是令人讚嘆的動物,而且你還不能用網子捕捉牠們 我們還得帶著攝影機親自去那裡觀察 所以每次我們去都會發現新品種生物 海洋裡充滿了生物 然而最深的海洋 -- 當我們去那個洋脊時還發現了溫泉 我們一度很確信那裡沒有生物,因為那水有毒 也因為它是那麼深,水壓足以把鐵達尼號壓垮 就像你可以把手中的空杯子壓扁一樣 我們真的以為那裡不會有生物了 但是我們卻發現了比熱帶雨林還多的生物 其多樣性及密度也比熱帶雨林高 那麼舉個實例,有一次我們往潛水艇窗外一看 我們發現了一個會徹底改變 我們對地球生命的想法的東西,就是 你並不一定要陽光才能讓生物存活 海底還有一些大型的動物 -- 有些看起來還很眼熟 這玩意叫小飛象,我很愛牠。小飛象棒極了 這傢伙,噢,我真希望我能拍到更多的影像 我們很想搞個探險,一起去看看這個東西 希望能在一年內出發 上網去看吧 Vampyroteuthisinfornalis (幽靈蛸拉丁文學名),一般叫吸血鬼烏賊 酷極了 在最深最暗的海裡,牠有著發光的觸器 所以我如果像牠一樣靠近你,在黑暗中我把我的手臂伸出 你只會看到這些小小的發光點圍繞你 但同時我已經靠近你了 如果牠要逃跑,牠就把這些發光的吸盤 放在屁股上,看起來就像眼睛 屁股上長着發光的眼睛,很酷吧? 真是非常非常奇妙的動物(笑聲) 吸血鬼烏賊,當牠覺得危險時 就把背鰭覆蓋自己的身體 捲起來成球狀。不可思議的動物。 這艘船,這艘「夢幻之船」 -- 在一百年前的 四月這艘船應該抵達紐約 就是鐵達尼號。去年我與人一起領了探險隊去哪裡 我們從這艘船上學到了好多東西 鐵達尼號對生物學而言是個很有趣的地方 因為動物搬到鐵達尼號去住了 微生物正在腐蝕鐵達尼號的船體 這裡就是傑克說自己是世界之王時的鐵達尼號船頭 所以,我們進展良好,而讓我興奮之處是 有一天我們會作出虛擬的鐵達尼號,你可以坐在家中 搖著搖桿,帶著耳機 親自實際地探索鐵達尼號 這就是我們想做的 -- 作出虛擬的世界,所以探險世界不再是我大衛蓋羅 或其他人的工作,而是你自己去做 你自己去探險 那麼以下是我的結論 海洋還是「蠻荒之地」 我無法告訴你這有多重要 因為海洋對我們真的很重要 有七十億人口住在地球 所有的人都被海洋影響著,因為海洋 控制著你呼吸的空氣,你喝的水 以及你吃的食物 海洋對這些事都有某種程度的影響 而我們對海洋的探勘真的是少之又少 -- 僅僅百分之五 我想要留給你們的事情 就在我展示的這些很酷的「百分之五」中 每次我們去海裡潛水,我們都會發現更多 更酷的東西,我們對海洋都有新的發現 所以在其他的百分之九十五裡有甚麼? 我們是已經找到了所有令人興奮的東西,還是還有更多? 我要在這裡告訴大家,海洋充滿了驚喜 我很愛一句馬歇爾·普魯士的名言: 「真正的探險航行不在發現新大陸」 在這方面,我們的確有發現「新大陸」 「而在於擁有新的眼界。」 所以今天我希望藉由這些展示 能讓你們以新的眼光來看地球 並且我要你們能首次以不同的角度來思考它 謝謝。謝謝。 (掌聲)
