结构时间轴展开收起

HA4_gVHBUXc 0:02–1:03 — Deep below the warm tropical waters of the Pacific Ocean, there is a dark and almost frozen world.
HA4_gVHBUXc 1:09–2:17 — Much of what we know about this secretive place comes from rare specimens that have been brought up by remote probes, or are occasionally caught by deep-sea fishing.
HA4_gVHBUXc 2:25–3:47 — They had already taken hundreds of soundings, a back-breaking job in all weathers, from blistering tropical heat, to frozen polar waters.
HA4_gVHBUXc 3:53–5:13 — This sounds far-fetched to us today, but in those days, such fears were very real. Eventually the weight hit the bottom, more than eight kilometres down.
HA4_gVHBUXc 5:20–6:38 — And if you wish you could bury your data that far down so no one could use it online, but you don’t have a submersible to get down there, don’t worry - we’ve got the next best thin…
HA4_gVHBUXc 6:42–8:03 — An astonishing ninety per cent of all earthquakes are caused by movements of this 40,000 kilometre fracture, where rock faces, many kilometres deep into the Earth, grind together a…
PaErPyEnDvk 0:01–1:08 — We've visited all the remote islands, conquered the Arctic, and penetrated the deepest jungles. But there is still one place to explore.
PaErPyEnDvk 1:15–2:20 — The seafloor at this depth is akin to the Amazon rainforest, and is often covered with coral reefs, algae, and other sea plants that are home to a plethora of sea animals.
PaErPyEnDvk 2:24–3:24 — At that depth, the pressure is like having 200 cars stacked on top of you. Yet we've only completed 3% of our journey.
PaErPyEnDvk 3:29–4:33 — They can be up to 50 metres in length, but are only as wide as a broomstick.

字幕可核对事实展开收起

字幕依据：Much of what we know about this secretive place comes from rare specimens that have been brought up by remote probes, or are occasionally caught by deep-sea fishing. Strange creatures that have adapted to living in conditions that we still don’t fully understand are sometimes washed up on our shores. HA4_gVHBUXc@1:09
字幕依据：This sounds far-fetched to us today, but in those days, such fears were very real. Eventually the weight hit the bottom, more than eight kilometres down. What they had found is now known as the Mariana Trench, and if they had been just a little further to the West, they would have found the deepest hole in the surface of our planet. HA4_gVHBUXc@3:53
字幕依据：And if you wish you could bury your data that far down so no one could use it online, but you don’t have a submersible to get down there, don’t worry - we’ve got the next best thing. All of your information being so readily available is down to data brokers; companies that collect and sell your personal info like autographs hunters outside a pop star’s hotel. HA4_gVHBUXc@5:20
字幕依据：The seafloor at this depth is akin to the Amazon rainforest, and is often covered with coral reefs, algae, and other sea plants that are home to a plethora of sea animals. So far, we've focused most of our attention on this comparatively pleasant environment, where we fish, swim, pollute, and do science. PaErPyEnDvk@1:15
字幕依据：Or the frilled shark, with its impressive set of 300 teeth, which are curved backwards to hook their victims in their mouths. Below the 3800 mark, as deep as the grave of the Titanic, we are now at abyssal depths. Preserving every last bit of energy is crucial for survival. PaErPyEnDvk@5:47
字幕依据：At just a few sites around the world, the ocean’s final underworld plummets deeper still through great rifts etched by tectonic processes. These are the Trenches, or the Hadalpelagic. When it comes to unlocking their secrets, each of these zones pose a greater challenge than the last. VlcI2Vu5uV4@2:56
字幕依据：ROV SuBastian, a robot owned and operated by the nonprofit Schmidt Ocean Institute. And, depth rated to 4 and a half kilometres, its range covers the entirety of the Midnight Zone. Controlled from the surface via a tether, SuBastian shines a light on the deep, and reveals a glimpse at the veiled expanse beneath the ocean surface. VlcI2Vu5uV4@4:07
字幕依据：Primary production is made possible near the surface by the rays of sunlight that filter through the waves. Microscopic plant-like animals, called phytoplankton, take on the role of producers, converting water and carbon dioxide into oxygen and glucose via photosynthesis. VlcI2Vu5uV4@6:23
