1 00:00:07,540 --> 00:00:08,841 [Victor] No manned submersible 2 00:00:08,875 --> 00:00:10,142 has ever been down 3 00:00:10,176 --> 00:00:11,844 to the bottom of the Arctic Ocean. 4 00:00:11,878 --> 00:00:14,480 I'm going backwards down a canyon 5 00:00:14,514 --> 00:00:15,914 in a submarine in the Arctic Ocean. 6 00:00:15,949 --> 00:00:17,449 It's easily the most complex terrain 7 00:00:17,484 --> 00:00:19,318 I've ever navigated in. 8 00:00:19,352 --> 00:00:21,453 [Heather] Oh, it's something big, dead ahead! 9 00:00:21,488 --> 00:00:23,389 [Victor] What is it? 10 00:00:23,423 --> 00:00:25,724 This is pack ice 11 00:00:25,759 --> 00:00:28,060 and this can kill ships. 12 00:00:29,929 --> 00:00:32,965 [Rob] The wind chill is minus eight. 13 00:00:32,999 --> 00:00:34,633 If you fall in, 14 00:00:34,667 --> 00:00:36,335 you have two minutes left. 15 00:00:40,240 --> 00:00:42,574 [dramatic music playing] 16 00:00:42,609 --> 00:00:44,343 [Demetri] Humankind has explored 17 00:00:44,377 --> 00:00:45,911 every continent on earth. 18 00:00:47,313 --> 00:00:50,115 We've climbed its tallest mountains... 19 00:00:51,518 --> 00:00:54,753 and even journeyed into space. 20 00:00:54,788 --> 00:00:56,288 [man] Thank you, Mr. President. 21 00:00:56,322 --> 00:00:58,724 [Demetri] But there's a vast swathe of our own planet 22 00:00:58,758 --> 00:01:00,793 that has remained a mystery. 23 00:01:01,895 --> 00:01:05,531 [dramatic music playing] 24 00:01:05,565 --> 00:01:07,699 [Demetri] The deep ocean. 25 00:01:07,734 --> 00:01:10,335 Stretching down over 35,000 feet 26 00:01:10,370 --> 00:01:12,371 into crushing pressures, 27 00:01:12,405 --> 00:01:15,207 it's been near impossible to reach. 28 00:01:15,241 --> 00:01:16,809 Until now. 29 00:01:18,244 --> 00:01:20,112 New engineering breakthroughs 30 00:01:20,146 --> 00:01:22,481 are driving an audacious global mission 31 00:01:22,515 --> 00:01:25,918 to dive the deepest points of all the five oceans, 32 00:01:25,985 --> 00:01:28,854 for the first time in history. 33 00:01:28,888 --> 00:01:31,523 These pioneers will push technology 34 00:01:31,558 --> 00:01:32,491 to the limit. 35 00:01:32,525 --> 00:01:33,425 What the hell was that? 36 00:01:33,460 --> 00:01:35,594 We have leaking hatch. 37 00:01:35,628 --> 00:01:37,663 [Demetri] ...to open up this final frontier, 38 00:01:37,697 --> 00:01:39,398 as never before. 39 00:01:39,432 --> 00:01:41,467 [Cassie] Trying to like mentally put yourself 40 00:01:41,501 --> 00:01:43,635 at the bottom is just mind-blowing. 41 00:01:43,670 --> 00:01:45,704 [Demetri] Mapping hidden landscapes, 42 00:01:45,738 --> 00:01:47,773 discovering unknown life forms. 43 00:01:47,807 --> 00:01:49,741 [Alan] What on earth is that? 44 00:01:49,776 --> 00:01:53,011 [Demetri] And unlocking the secrets of how life 45 00:01:53,046 --> 00:01:54,580 in the extreme deep ocean 46 00:01:54,614 --> 00:01:57,015 affects our entire planet. 47 00:02:08,561 --> 00:02:11,063 [dramatic music playing] 48 00:02:11,097 --> 00:02:12,197 [man] Yeah, go ahead. 49 00:02:12,232 --> 00:02:14,099 [Demetri] Explorer Victor Vescovo 50 00:02:14,134 --> 00:02:16,635 is self-funding a multi-million-dollar 51 00:02:16,669 --> 00:02:18,303 daredevil mission to explore 52 00:02:18,338 --> 00:02:20,772 the extremes of the deep. 53 00:02:20,807 --> 00:02:23,742 [Victor] 70% of this planet is covered in the ocean. 54 00:02:23,776 --> 00:02:26,478 Most of the biomass of the world 55 00:02:26,513 --> 00:02:28,347 is not in the Amazonian rainforest 56 00:02:28,381 --> 00:02:29,648 or the jungles of Africa. 57 00:02:29,682 --> 00:02:31,583 Most of the species on this planet 58 00:02:31,618 --> 00:02:33,318 are in the ocean, and yet, 59 00:02:33,353 --> 00:02:34,720 we still really don't understand 60 00:02:34,754 --> 00:02:36,021 how the ocean works. 61 00:02:38,358 --> 00:02:40,926 [Demetri] On his pioneering global quest to dive 62 00:02:40,960 --> 00:02:43,729 to the deepest points of all of the five oceans, 63 00:02:43,763 --> 00:02:45,864 Victor has conquered the Atlantic. 64 00:02:45,899 --> 00:02:47,399 [cheers and applause] 65 00:02:47,433 --> 00:02:49,334 [Demetri] The Southern Ocean, 66 00:02:49,369 --> 00:02:51,837 the Indian Ocean, 67 00:02:51,871 --> 00:02:54,606 and the Pacific. 68 00:02:54,641 --> 00:02:57,676 [dramatic music playing] 69 00:02:57,710 --> 00:02:59,945 [Demetri] But the success of the entire mission 70 00:02:59,979 --> 00:03:02,414 now hangs in the balance. 71 00:03:02,448 --> 00:03:04,216 You've got to do all five. 72 00:03:04,250 --> 00:03:06,084 It's just like climbing a mountain, 73 00:03:06,119 --> 00:03:07,886 you can't go all the way up 74 00:03:07,921 --> 00:03:09,221 except for the last hundred feet 75 00:03:09,255 --> 00:03:10,889 and say you've climbed it. 76 00:03:10,924 --> 00:03:13,292 [Demetri] Victor will fail unless he can conquer 77 00:03:13,326 --> 00:03:15,894 the coldest of them all, 78 00:03:15,929 --> 00:03:17,396 the Arctic. 79 00:03:18,765 --> 00:03:20,132 This treacherous ocean 80 00:03:20,166 --> 00:03:23,135 envelopes the top of our planet. 81 00:03:23,169 --> 00:03:27,406 In winter, around 80% of it is covered in ice. 82 00:03:27,440 --> 00:03:28,774 [Rob] From here it's only 83 00:03:28,808 --> 00:03:30,909 a few hundred miles to the North Pole. 84 00:03:30,944 --> 00:03:33,178 So, we are about as far north as you can get 85 00:03:33,213 --> 00:03:34,880 and still be afloat. 86 00:03:36,316 --> 00:03:38,250 [Victor] There's going to be a lot of anxiety 87 00:03:38,284 --> 00:03:40,319 because a lot of things can go wrong 88 00:03:40,353 --> 00:03:42,854 because of the harsh conditions up here. 89 00:03:42,889 --> 00:03:45,257 [Demetri] Temperatures here can fall 90 00:03:45,291 --> 00:03:48,493 to as low as minus 58 degrees Fahrenheit, 91 00:03:48,528 --> 00:03:51,863 and have claimed the lives of many past explorers. 92 00:03:55,268 --> 00:03:58,604 [Victor] This is pack ice, this can kill ships. 93 00:03:59,706 --> 00:04:02,708 The ice up here, it's moving and it grows 94 00:04:02,742 --> 00:04:03,942 and it shrinks, 95 00:04:03,977 --> 00:04:05,444 so it's an unpredictable beast. 96 00:04:05,478 --> 00:04:06,979 If we wait too long, 97 00:04:07,013 --> 00:04:08,180 it can actually move south 98 00:04:08,214 --> 00:04:10,182 and can cover the drop zone. 99 00:04:12,252 --> 00:04:14,987 [Demetri] The team's target is 170 miles 100 00:04:15,021 --> 00:04:17,422 from the Norwegian island of Svalbard. 101 00:04:17,457 --> 00:04:19,658 It's a depression in the Arctic sea bed 102 00:04:19,692 --> 00:04:22,060 more than 18,000 feet down. 103 00:04:22,128 --> 00:04:23,395 The Molloy Deep, 104 00:04:23,429 --> 00:04:25,664 also known as the Molloy Hole. 105 00:04:28,735 --> 00:04:30,969 [Victor] No manned submersible has ever been down 106 00:04:31,004 --> 00:04:32,904 to the bottom of the Arctic Ocean. 107 00:04:36,042 --> 00:04:37,342 So, I will be the first person 108 00:04:37,377 --> 00:04:39,011 to actually see the Molloy Deep. 109 00:04:40,113 --> 00:04:42,447 Which is always exciting, to be the first. 110 00:04:43,983 --> 00:04:47,319 [Demetri] The Arctic is not the world's deepest ocean, 111 00:04:47,353 --> 00:04:50,055 but amazingly, the slightly squashed shape 112 00:04:50,089 --> 00:04:52,557 of our planet means that if Victor succeeds 113 00:04:52,592 --> 00:04:54,493 in diving to the Molloy Deep, 114 00:04:54,527 --> 00:04:56,828 he will be closer to the center of the earth 115 00:04:56,863 --> 00:04:59,197 than anyone has ever gone before. 116 00:05:02,035 --> 00:05:04,169 To succeed, Victor has commissioned 117 00:05:04,203 --> 00:05:06,738 a ground-breaking prototype submersible. 118 00:05:07,907 --> 00:05:09,474 [Kelvin] That's good there, perfect. 119 00:05:09,509 --> 00:05:10,709 [Rob] The world has never seen 120 00:05:10,743 --> 00:05:12,210 a vehicle like this before. 121 00:05:12,245 --> 00:05:14,746 So this is the first-time that humankind 122 00:05:14,781 --> 00:05:17,582 have had a vehicle that can go to any ocean, 123 00:05:17,617 --> 00:05:19,217 any depth, at any time. 124 00:05:19,252 --> 00:05:21,586 This is like a spacecraft. 125 00:05:24,991 --> 00:05:26,792 [Demetri] The team faced extreme cold 126 00:05:26,826 --> 00:05:28,660 in the Southern Ocean. 127 00:05:30,630 --> 00:05:32,798 But the Arctic Ocean is even colder, 128 00:05:32,832 --> 00:05:34,199 and will push the submersible 129 00:05:34,233 --> 00:05:35,878 even closer to its limits. 130 00:05:35,902 --> 00:05:38,870 Its batteries are particularly vulnerable. 131 00:05:38,905 --> 00:05:42,207 The water temperature I think is around minus one Celsius. 132 00:05:42,241 --> 00:05:45,410 We've got six lithium batteries on board. 133 00:05:45,445 --> 00:05:47,346 You know, in the back of your mind, you're thinking 134 00:05:47,380 --> 00:05:48,647 are they going to handle this? 135 00:05:48,681 --> 00:05:51,817 If we lose one, no big deal, we'll keep going. 136 00:05:51,851 --> 00:05:54,186 You know, we start losing two and three... 137 00:05:57,523 --> 00:05:59,191 [Demetri] The team have finally reached 138 00:05:59,225 --> 00:06:01,026 the Molloy Deep. 139 00:06:01,060 --> 00:06:02,928 There can be just a few weeks a year 140 00:06:02,962 --> 00:06:05,731 when the site is clear enough of ice to dive. 141 00:06:05,765 --> 00:06:07,099 They will need to make the most 142 00:06:07,133 --> 00:06:09,735 of the Arctic summer's 24-hour daylight 143 00:06:09,769 --> 00:06:12,537 as they begin scanning for the ocean's deepest point. 144 00:06:12,572 --> 00:06:14,373 [Heather] We use a piece of equipment called 145 00:06:14,407 --> 00:06:15,774 a 'multibeam echosounder' 146 00:06:15,808 --> 00:06:18,410 we use sound which we send from the ship 147 00:06:18,444 --> 00:06:20,846 down to the seabed, it bounces back up 148 00:06:20,913 --> 00:06:24,449 and that will give us a 3D model of the seabed. 149 00:06:24,484 --> 00:06:26,251 The other four are good, going for five. 150 00:06:26,285 --> 00:06:28,787 [Demetri] To survive, the sub will need to withstand 151 00:06:28,821 --> 00:06:30,889 pressures the equivalent of being crushed 152 00:06:30,923 --> 00:06:33,458 by the weight of a cruise ship. 153 00:06:33,493 --> 00:06:37,295 But how will the sub cope with the arctic extremes? 154 00:06:37,330 --> 00:06:41,166 The team have decided to launch an exploratory dive. 155 00:06:41,200 --> 00:06:44,770 The sonar has detected a promising landing zone 156 00:06:44,804 --> 00:06:46,738 at around half the depth of the ocean, 157 00:06:46,773 --> 00:06:50,675 still a crushing 6,500 feet deep. 158 00:06:50,710 --> 00:06:52,244 It's on the slopes of a giant 159 00:06:52,278 --> 00:06:54,880 underwater mountain, or 'seamount'. 160 00:06:56,816 --> 00:06:59,050 It was formed from near-molten rock 161 00:06:59,085 --> 00:07:00,952 forced up from under the seabed 162 00:07:00,987 --> 00:07:03,155 around three million years ago. 163 00:07:07,226 --> 00:07:09,661 Biologist Alan Jamieson is hoping that 164 00:07:09,695 --> 00:07:11,830 this pioneering dive might also add 165 00:07:11,864 --> 00:07:13,532 to the expedition's growing list 166 00:07:13,566 --> 00:07:16,501 of newly-discovered deep-sea species. 167 00:07:16,536 --> 00:07:17,869 The Molloy Seamount is the size 168 00:07:17,904 --> 00:07:19,237 of a pretty big mountain. 169 00:07:19,272 --> 00:07:20,739 There's a constant rain 170 00:07:20,773 --> 00:07:22,407 of organic matter coming down. 171 00:07:22,442 --> 00:07:23,842 We're looking at habitats 172 00:07:23,876 --> 00:07:25,977 which we think will be covered in life. 173 00:07:26,012 --> 00:07:28,713 [Demetri] Alan decides to launch lander probes 174 00:07:28,748 --> 00:07:30,549 onto the seamount. 175 00:07:30,583 --> 00:07:33,051 Baited cameras and traps will help in his search 176 00:07:33,085 --> 00:07:35,387 for new species adapted to survive 177 00:07:35,421 --> 00:07:37,289 in the Arctic deep. 178 00:07:37,323 --> 00:07:39,090 [Alan] Okay, Heather, pull it! 179 00:07:40,793 --> 00:07:42,994 [Demetri] With the lander probes descending, 180 00:07:43,029 --> 00:07:44,930 it's time to launch the

weather holding for now, 385 00:17:16,402 --> 00:17:20,004 the sonar team have detected a strange signal 386 00:17:20,039 --> 00:17:21,773 which could point to an unusual 387 00:17:21,807 --> 00:17:24,475 geological feature on the seamount. 388 00:17:24,510 --> 00:17:26,110 It could be something. 389 00:17:26,145 --> 00:17:27,945 [Heather] So the data that we're looking at 390 00:17:27,980 --> 00:17:29,347 from the sonar, 391 00:17:29,381 --> 00:17:32,050 it does a sort of show a diffuse cloud, 392 00:17:32,084 --> 00:17:34,252 something erupting on the seabed down there, 393 00:17:34,286 --> 00:17:35,553 a vent system. 394 00:17:37,589 --> 00:17:40,191 [Demetri] Finding the vents could give geologists 395 00:17:40,225 --> 00:17:43,127 new insight into how the Arctic Ocean's seabed 396 00:17:43,162 --> 00:17:44,962 is being formed. 397 00:17:44,997 --> 00:17:48,566 It'd be such a huge find to find it. 398 00:17:48,600 --> 00:17:51,702 [Demetri] It's an opportunity they can't afford to miss. 399 00:17:51,737 --> 00:17:53,805 Really unusual vent features 400 00:17:53,839 --> 00:17:55,907 have never been documented in this area 401 00:17:55,941 --> 00:17:58,176 but all indications are that we should be able 402 00:17:58,210 --> 00:17:59,777 to find them and that would be a first. 403 00:18:01,413 --> 00:18:04,248 [Demetri] The sub could now face a new threat. 404 00:18:04,283 --> 00:18:06,918 The Arctic may be the world's coldest ocean, 405 00:18:06,952 --> 00:18:08,719 but the water coming out of the vents 406 00:18:08,754 --> 00:18:11,322 might be dangerously hot. 407 00:18:11,356 --> 00:18:13,257 [Heather] We're probably looking at temperatures 408 00:18:13,292 --> 00:18:16,027 of the erupting fluids of about 90 degrees. 409 00:18:16,061 --> 00:18:17,962 Even at 90 degrees C 410 00:18:17,996 --> 00:18:19,230 is problematic. 411 00:18:19,264 --> 00:18:20,965 [tense music playing] 412 00:18:30,342 --> 00:18:32,376 [Demetri] On the hunt for undersea vents, 413 00:18:32,411 --> 00:18:35,780 the sub could be exposed to dangerously hot water. 414 00:18:35,814 --> 00:18:38,349 The team knows that the sub's spherical cockpit 415 00:18:38,383 --> 00:18:41,619 has potential weak points that could be vulnerable. 416 00:18:41,653 --> 00:18:43,387 [Patrick] I understand that these hydrothermal vents 417 00:18:43,422 --> 00:18:45,223 are about 90 degrees Celsius, 418 00:18:45,257 --> 00:18:47,725 so the acrylic viewports would be the thing 419 00:18:47,759 --> 00:18:49,794 that you'd be most concerned about. 420 00:18:49,828 --> 00:18:51,729 The design of the vehicle is based 421 00:18:51,763 --> 00:18:53,965 around water temperatures 422 00:18:53,999 --> 00:18:56,200 not being more than 10 Celsius 423 00:18:56,235 --> 00:18:57,702 at that sort of depth. 424 00:18:57,736 --> 00:18:59,737 [Demetri] If the acrylic viewports are melted 425 00:18:59,771 --> 00:19:02,573 by the hot vents, the super-high-pressure water 426 00:19:02,608 --> 00:19:04,942 will enter the sub 427 00:19:04,977 --> 00:19:07,745 and fill it in a milli-second. 428 00:19:07,779 --> 00:19:09,147 To avoid dropping the sub 429 00:19:09,181 --> 00:19:11,082 directly onto potentially damaging 430 00:19:11,116 --> 00:19:13,184 hot water vents, 431 00:19:13,218 --> 00:19:14,952 the team select a landing zone 432 00:19:14,987 --> 00:19:17,788 a safe distance away. 433 00:19:17,823 --> 00:19:19,190 Victor will then need to navigate 434 00:19:19,224 --> 00:19:20,925 across the precipitous slopes 435 00:19:20,959 --> 00:19:23,494 of the seamount to his target. 436 00:19:26,965 --> 00:19:28,666 Okay, here we go, let's do this! 437 00:19:28,700 --> 00:19:30,001 [Demetri] Heather is joining Victor 438

00:19:37,808 [Demetri] She will become the first woman 442 00:19:37,843 --> 00:19:39,143 to descend to the Arctic deeps. 443 00:19:39,178 --> 00:19:40,478 [Kelvin] How's everything looking there? 444
