  • Hi, I'm Carl Azuz.

    嗨,我是 Carl Azuz。

  • Thalassophile is a word you don't hear very often.

    Thalassophile (愛海成癡) 是一個不常聽到的詞。

  • If you know what it means and, especially, if you happen to be one, you're gonna love this special edition of our show.


  • Simply put, a thalassophile is someone who loves the sea, and the deep blue is where we're headed today, specifically the deepest known part of the ocean.


  • Start in the pacific.


  • If you can find the northern Mariana Islands on the eastern part of the Philippine Sea, you're only about 330 miles northeast of the Mariana Trench.

    在菲律賓海的東部找到北馬里亞納群島後,馬里亞納海溝便位於該處西南方向 330 英里的位置。

  • It's located 7 miles beneath the ocean's surface.

    它位於海面下 7 英里處。

  • It's what "National Geographic" describes as "a scar in the earth's crust".


  • This trench extends for more than 1,500 miles and it's 43 miles wide on average, so this is a pretty big gouge on the ocean floor.

    這條海溝延伸了 1500 多英里,平均寬度為 43 英里,在海底留下了相當大的一個切口。

  • And if you go to the southern end of it, you'll find its deepest point.


  • This remote place is called the Challenger Deep.


  • It takes patience to get there, even after you sail right over it.


  • The submersibles that can withstand the pressure take hours to dive this deep.


  • And even though thousands of people have climbed to the top of Mount Everest, which is 5-and-a-half miles higher than sea level, only a couple dozen have reached the 7-mile depth of the Challenger deep, so it's largely unexplored.

    儘管有成千上萬的人爬上了比海平面高 5.5 英里的珠穆朗瑪峰頂,但只有幾十個人到達了挑戰者號深淵的 7 英里深度,所以它基本上沒有被探索過。

  • But we know someone who has been there: His name is Rob McCallum, he's from New Zealand.

    但我們知道有誰到達過:那就是來自紐西蘭的 Rob McCallum。

  • Last April, he and Australian Tim Macdonald became the first people from their countries to dive this record depth.

    去年 4 月,他和澳大利亞人 Tim Macdonald 成為了各自國家第一到達這個破紀錄深度的人。

  • They were kind enough to provide us with the video you're about to see, and I had the opportunity to interview Mr. McCallum about the experience not long after he hit rock bottom and then resurfaced in the Spring of 2021.

    他們人很好地向我們提供了你等一下即將看到的影片,而且我之前有幸能在 McCallum 先生於 2021 年春天潛入谷底深處並重新上浮不久後採訪他。

  • So, hold your breath, and let's dive in.


  • It's the last, uh... unexplored frontier on Earth.


  • Um... we know very little about this... this region, what we call the Hadal Zone, which is that area of the ocean below 6,000 meters or 20,000 feet.

    我們對這一地區知之甚少。我們把這個在 6 千公尺 (2 萬英呎) 以下的海洋地區稱為超深淵帶。

  • You can't just get there in a normal submarine; what sort of vehicle does it take to withstand the pressures there?


  • That's a very interesting question, because pressure is, uh, entirely relative.


  • When a spacecraft goes up into space, uh, they're only experiencing a... a pressure change of one atmosphere between the inside of the, uh, spacecraft and the outside.


  • We are dealing with a pressure diffedifferential of around 1,100 atmospheres.

    而我們要處理的是大約 1100 個大氣壓力的壓力差。

  • So, we dive in a titanium sphere, which is able to withstand 100,000 tons of pressure.

    因此我們使用一個能夠承受 10 萬噸壓力的鈦合金球體中潛水。

  • Just on the hatch, uh, through which we get into the submarine, just the hatch alone, has 2,200 tons, or around 5 fully-laden Boeing 747s, pushing down on it.

    光是我們走進潛水艇時經過的艙門,光是那個艙門上面就承受了 2200 公噸的壓力,相當於 5 架滿載乘客的波音 747 客機。

  • That's... that's incredible, I mean, somebody can't go out and... and buy that; how does one acquire a vehicle like that?


  • This vehicle was made for this specific purpose.


  • It was designed and built by Triton Submarines in Florida, specifically to be able to voyage down through 7-and-a-half miles of, um, water column to get to the bottom.

    它由佛羅里達州的 Triton 潛水艇公司專門設計和建造,能夠通過 7.5 英里深的水體向下航行,直達海底。

  • And that's why it's got kind of an interesting shape.


  • It looks like a pillow that's on its side.


  • And that's so that it can drop down through the water column very, very quickly.


  • You said very quickly; how long does it take to get to that depth?


  • It takes around 4-and-a-half hours to get to the deepest point of the world's ocean.

    到達全世界海洋的最深處大約需要 4.5 小時。

  • We go down through the water at about 6 feet per second.

    我們以每秒約 6 英尺的速度下潛。

  • And coming back?


  • Uh, we release ballast weight on the bottom to, uh, to just spring us off the bottom and head for the surface, and so it's about a 3-and-a-half-hour ride home.

    我們會把放掉壓艙物來讓我們彈回海面,所以回程大概是 3.5 個小時左右。

  • What are you seeing when you get to the ocean floor in the deepest part of it?


  • This is the most fantastic part of, uh, what we're doing; it's true exploration.


  • You know, we never know what we're going to see.


  • Uh, every dive has yielded something fascinating, often, something new to science.


  • Uh, we are seeing, uh, creatures for the first time; we are discovering entire landscapes which were previously unknown.


  • That's still a full day just in travel time.


  • So, how much time does that give you on the ocean's floor?


  • We tried to, uh, stay down for 3-5 hours on the bottom.

    我們盡量試著在海底停留 3 到 5 個小時。

  • You know, it's a big investment of time and energy; it takes the entire team to get this vehicle prepared and get it down.


  • And, so, we tried to use every minute possible on the bottom.


  • Our submersible has three view ports, one for each of the occupants, but also one central one that allows us to see down to the sea floor.


  • But we're also surrounded by, uh, very high definition cameras that are all linked to a screen in front of us and we can look in any direction, uh, outside.


  • And that's important because we don't really know where we're going; we're almost always the very first humans that have ever been there.


  • And, so, although we have a three-dimensional map that we've made the day before, we need a very, um, good view outside to see what's coming.


  • You know, for humans, we don't really fear what we can't, uh, sense.


  • And, so, when you're in an airliner and you're looking out, you don't naturally think of the wind going past at 500 miles per hour and it's minus 50 out there and there's not enough air to breathe.

    因此當你坐在一架客機上看著外面時,你不會自然地想到外面的風速超過每小時 500 英里,溫度是零下 50 度,而且沒有足夠的空氣可供你呼吸。

  • You just... I can see a town or I can see a truck.

    你只會... 覺得「哇下面有個城鎮耶!」,或是「下面有輛卡車!」。

  • And the same in the sub; there's no sensation of movement, there's no sensation of sound, um, you can't hear or feel anything from outside.


  • It's just a very peaceful, relaxing cruise, uh, into the unknown.


  • I think that we know so little about, uh, the ocean that we barely understand what questions to ask, let alone, um, have the ability to... to understand the answers.


  • My role and the role of... of the team that I work with is to simply open the door.


  • This is the first vehicle in all of human history that has the ability to reach the deep ocean, uh, in any ocean at any depth at any time.


  • It's... it's... it's... a... akin to the Wright Brothers with the first flying machine.


  • This is just the first baby steps.


  • I know the technology might be a way away from creating a sort of ocean exploration station that can withstand depths like that.


  • But we have reported onthere... there is more funding and investment in underwater exploration stations.


  • I mean, how important would you feel those would be as contrasted with, let's say, the International Space Station?


  • Both are important, don't get me wrong; I'm... I'm not taking a shot at space travel


  • But, you know, space is a vast void, a vacuum, uh, that so far has proved to be lifeless.


  • The ocean is nothing like that.


  • The ocean is full of life, you know, right from the surface all the way down to the very, very bottom.


  • I think, before we leave home and start exploring the heavens, we should at least, uh, explore our own backyard more thoroughly.


  • I think that many of the answers to our collective future are going to be found in the ocean, and some of those in the deep ocean.


  • The answers to how we're going to handle all the carbon in the atmosphere.


  • The answers to, uh, the dynamics of our ocean and how we can arrest, uh, the decline of the ocean.


  • But also the things that we might discover in terms of, um, valuable compounds for medicines and that sort of thing.


  • So, why do you think there's so much interest in space exploration when we could be exploring what we have right here?


  • I think it's as simple as when we gaze up at the heavens, we arewe have a sense of wonder, uh, what's out there, you know, what can we find?


  • We always look skyward because we're terrestrial mammals; we... we... we look up to the heavens.


  • When we look into the water, we don't really see that much.


  • We see an opaque uh, plainplane... uh, platform that we can pull fish out of, maybe go for a swim in, but we don't actually go too far down.


  • You know, my dive was about 36,000 feet; most humans never get below about 300 feet.

    你知道,我的潛水深度約為 3 萬 6 千英尺,而大多數人類從未潛入到 300 英尺以下。

  • So there's a long way to go yet.


  • 10-second trivia: What is the most abundant fish in the world?


  • Herring, Bristlemouth, Minnow, or Sunfish.


  • Scientists believe the most numerous fish in the world are Bristlemouths, or light fishes.


  • That's our catch of the day; it is surely fun to take a deep dive into such a "marine-teresting" topic.


  • There are "oceans" of possibilities, sights to see, facts in the "swim" beneath the surface, "schools" of thought...


  • I mean, what better way to get a "gyro-education" than to "immerse" yourself in a "current" event?


  • Today's shout-out goes out to Grenada High School located in Grenada, Mississippi.


  • There is one place we look for the schools we mention; it's our YouTube channel at

    我們會在我們 YouTube 頻道尋求打招呼的學校,網址是。

  • So, please subscribe and leave your comments on our most recent show right there.


  • That's all for our show today, I'm Carl Azuz.

    我們今天的節目就到此告一段落,我是 Carl Azuz。

Hi, I'm Carl Azuz.
