Really careful. 95 00:05:26.393 --> 00:05:30.430 So the hazards are, you know, we are going deep, 96 00:05:30.497 --> 00:05:33.567 and the fact that we're diving around a human-made object, 97 00:05:33.634 --> 00:05:38.805 we're around a wreck structure with potentially strong current. 98 00:05:40.407 --> 00:05:44.178 This wreck has been down there for 107 years, 99 00:05:44.244 --> 00:05:47.080 so, uh, it's inherently unstable, 100 00:05:47.147 --> 00:05:49.550 and she lies across the current, 101 00:05:49.616 --> 00:05:52.786 uh, which is running up to two knots at a time. 102 00:05:52.853 --> 00:05:57.224 Diving around a wreck presents a unique set of risks and concerns. 103 00:05:57.791 --> 00:06:00.394 The primary one being entanglement, you know, 104 00:06:00.460 --> 00:06:03.897 a wreck can have things like ropes and obstructions 105 00:06:03.964 --> 00:06:07.534 and things of that nature that present a hazard to the craft. 106 00:06:07.601 --> 00:06:12.606 The idea is to go here, and then we'll come up here and pretty much, I mean, 107 00:06:12.673 --> 00:06:15.976 everyone has told me not to get too close and to be extremely careful, 108 00:06:16.043 --> 00:06:17.811 because there are still wires. 109 00:06:18.378 --> 00:06:20.614 The success of the first dive is vital. 110 00:06:20.681 --> 00:06:23.817 It will allow the team to plot additional dives. 111 00:06:23.884 --> 00:06:26.920 Failure, and the expedition could end abruptly. 112 00:06:28.155 --> 00:06:29.756 Cool. If no one's got any questions, 113 00:06:29.823 --> 00:06:36.396 then our next gig is 6:45 up on the foredeck, uh, tomorrow morning. 114 00:06:40.601 --> 00:06:43.971 Preparation is over. Tomorrow, the team will attempt 115 00:06:44.037 --> 00:06:47.140 to dive to the most famous ship in history. 116 00:06:56.450 --> 00:07:01.388 Weather conditions now are worse than they were on the forecast yesterday. 117 00:07:04.625 --> 00:07:08.095 The first dive is due to be launching in less than an hour. 118 00:07:11.532 --> 00:07:13.700 But conditions aren't looking good. 119 00:07:14.635 --> 00:07:17.004 The crew's having to secure equipment. 120 00:07:17.638 --> 00:07:20.440 So, the biggest waves you can see coming through now are probably four, 121 00:07:20.507 --> 00:07:23.911 four and a half meters, which is pretty much double 122 00:07:23.977 --> 00:07:27.581 the maximum limit for the... To operate the sub. 123 00:07:38.592 --> 00:07:39.760 So, you called it. 124 00:07:39.860 --> 00:07:42.696 It's not a nice decision to make, and no one wants to make it, 125 00:07:42.763 --> 00:07:45.899 - but it's the one that needs to be made. - Yeah, I agree. 126 00:07:45.966 --> 00:07:47.467 And the people downstairs know? 127 00:07:51.104 --> 00:07:53.207 The first launch is aborted. 128 00:07:53.473 --> 00:07:58.212 If the bad weather doesn't pass soon, the entire mission will be in jeopardy. 129 00:07:58.278 --> 00:08:00.714 Let's go down and announce it to everybody. 130 00:08:09.022 --> 00:08:12.559 - Okay, good to go. - Good to go. 131 00:08:12.626 --> 00:08:15.829 Next morning, there's a break in the weather. 132 00:08:15.896 --> 00:08:17.197 Setting five minutes. 133 00:08:17.831 --> 00:08:19.366 Five minutes, okey-doke. 134 00:08:27.107 --> 00:08:28.375 The dive is on. 135 00:08:29.309 --> 00:08:31.245 We're going to the Titanic. 136 00:08:32.913 --> 00:08:33.914 Weather's not bad. 137 00:08:34.281 --> 00:08:37.093 It was rougher last night, I thought it was gonna be rough this morning, 138 00:08:37.117 --> 00:08:38.385 but it's laid down a bit, 139 00:08:38.452 --> 00:08:40.320 so I'm comfortable with this, 140 00:08:40.387 --> 00:08:43.056 we can launch in this. Let's send this bad boy to the bottom. 141 00:08:44.758 --> 00:08:49.196 This will be the first ever solo dive to Titanic. 142 00:08:49.263 --> 00:08:51.031 - Two minutes. - Two minutes. 143 00:09:01.008 --> 00:09:04.077 Good luck, Victor.

Absolutely. 467 00:32:32.486 --> 00:32:37.291 In those rare instances where we can provide identification 468 00:32:37.357 --> 00:32:43.263 of a piece to a descendant of someone who perished, 469 00:32:43.330 --> 00:32:45.799 I think it's very much appreciated. 470 00:32:46.667 --> 00:32:49.870 We all like to remember those, like, fairy tales of him, 471 00:32:49.937 --> 00:32:51.805 uh, dressed in his best, as he said, 472 00:32:51.872 --> 00:32:55.475 sipping brandy and just going down heroically, 473 00:32:55.542 --> 00:32:59.479 I guess, but, yeah, what I'm seeing here, 474 00:32:59.546 --> 00:33:01.715 like the crushed metal and everything, 475 00:33:01.782 --> 00:33:04.084 is just showing me a very different reality. 476 00:33:12.159 --> 00:33:15.062 Finding Guggenheim's state rooms allows the team 477 00:33:15.128 --> 00:33:18.932 to add another crucial part to their photogrammetry model. 478 00:33:21.068 --> 00:33:23.904 And then we're coming up now to the top. 479 00:33:23.971 --> 00:33:26.240 Okay, there's the overhang from A deck. 480 00:33:26.306 --> 00:33:28.542 Additional data from the most recent dive 481 00:33:28.609 --> 00:33:30.577 has now been added to the model. 482 00:33:30.644 --> 00:33:33.680 It's allowing Parks to understand other areas of Titanic 483 00:33:33.747 --> 00:33:35.215 in far more detail... 484 00:33:35.282 --> 00:33:38.652 It took us a while to recognize this. 485 00:33:39.019 --> 00:33:42.322 Including the cabin of Captain Edward John Smith, 486 00:33:42.890 --> 00:33:45.792 who famously went down with his ship. 487 00:33:47.227 --> 00:33:50.631 When Titanic was rediscovered in 1985, 488 00:33:50.697 --> 00:33:55.903 the contents of Captain Smith's bathroom were revealed to be largely intact, 489 00:33:55.969 --> 00:33:58.138 including his private bathtub. 490 00:33:59.773 --> 00:34:04.244 It's a tiny, but very tangible, detail of the lives of individuals 491 00:34:04.311 --> 00:34:06.880 who lived and worked aboard the ship. 492 00:34:07.814 --> 00:34:10.083 So Parks wants to see how it's faring. 493 00:34:11.185 --> 00:34:16.023 This entire overhead has now collapsed since we last saw it. 494 00:34:16.089 --> 00:34:22.062 Only a small sliver of the captain's bath tub remains. 495 00:34:22.129 --> 00:34:29.036 This collapse was exactly the kind of, uh, failure that we were expecting to find, 496 00:34:29.102 --> 00:34:31.772 and I expect this kind of collapse 497 00:34:31.839 --> 00:34:36.310 is gonna continue in various areas around the wreck in the years to come. 498 00:34:38.378 --> 00:34:41.748 The captain's quarters have lost their battle with decay. 499 00:34:45.986 --> 00:34:47.087 You can see... 500 00:34:47.154 --> 00:34:50.224 Next, Parks turns his attention to another area of the ship 501 00:34:50.290 --> 00:34:53.460 that's of great interest, the Marconi room. 502 00:34:55.128 --> 00:34:57.431 As the biggest and best ship of her day, 503 00:34:57.497 --> 00:35:00.634 Titanic contained state-of-the-art technology, 504 00:35:00.701 --> 00:35:04.638 including the famous Marconi radio transmitter. 505 00:35:04.705 --> 00:35:08.208 The set aboard Titanic was among the first of its kind ever built. 506 00:35:11.512 --> 00:35:14.515 It was housed in the Marconi room, located on the boat deck 507 00:35:14.581 --> 00:35:16.817 between the first and second funnels. 508 00:35:18.785 --> 00:35:20.087 The transmitter was used 509 00:35:20.153 --> 00:35:24.224 to receive warnings of icebergs and send distress messages, 510 00:35:24.291 --> 00:35:28.629 something ships hadn't been able to do until the end of the 19th century. 511 00:35:28.695 --> 00:35:32.466 My biggest fear is my favorite part of the wreck, 512 00:35:32.533 --> 00:35:34.468 the Marconi wireless telegraph room, 513 00:35:34.535 --> 00:35:39.339 is gone and any hope of recovering that transmitting apparatus and restoring it 514 00:35:40.474 --> 00:35:44.411 is no longer... Is no longer a possibility. 515 00:35:48.081 --> 00:35:51.218 On a previous expedition, Parks saw the Marconi room 516 00:35:51.285 --> 00:35:53.520 and its contents were in good condition. 517 00:35:53.587 --> 00:35:56.056 Now, he wants to view its current state in detail, 518 00:35:56.123 --> 00:35:59.993 as he couldn't see it clearly during his dive with Victor. 519 00:36:02.196 --> 00:36:05.265 I wanna go in here. I wanna see what that is, I wanna get in here. 520 00:36:05.332 --> 00:36:08.402 I can actually see rusticles hanging down inside, 521 00:36:08.468 --> 00:36:10.804 so that indicates there's a whole space in here. 522 00:36:12.673 --> 00:36:15.742 Parks is hoping the photogrammetry will allow him 523 00:36:15.809 --> 00:36:18.078 to see the Marconi room in far greater detail. 524 00:36:19.513 --> 00:36:22.749 The area that I'm interested in is right in this area right here. 525 00:36:22.816 --> 00:36:25.219 - Now, your data set falls off here... - Yeah. 526 00:36:25.285 --> 00:36:30.090 But, um, these holes right here are of special concern to me 527 00:36:30.157 --> 00:36:32.860 because this looks like the beginning of... 528 00:36:32.926 --> 00:36:35.996 - Now, now, pull out a little bit. - Sure. 529 00:36:36.063 --> 00:36:38.999 The three-dimensional photogrammetry is revealing 530 00:36:39.066 --> 00:36:42.302 a new depression in the roof of the Marconi room. 531 00:36:42.402 --> 00:36:43.737 It's gonna continue to fall, 532 00:36:43.804 --> 00:36:45.964 and there's gonna be... And next time we come out here, 533 00:36:46.006 --> 00:36:48.208 there's gonna be a new hole next to that one. 534 00:36:49.142 --> 00:36:53.080 We are definitely in a race against time here. 535 00:37:00.888 --> 00:37:03.790 An investigation into the condition of Titanic 536 00:37:03.857 --> 00:37:06.260 is revealing a mixed picture. 537 00:37:06.693 --> 00:37:09.563 Some of the wreck's features have deteriorated... 538 00:37:09.696 --> 00:37:12.599 - I see a glimpse of the tub. - Yeah. 539 00:37:12.666 --> 00:37:14.968 I can barely see it, and, yeah, it's devastated. 540 00:37:15.569 --> 00:37:17.638 Whilst others have barely changed. 541 00:37:17.738 --> 00:37:22.409 Overall, the wreck seems to be holding up surprisingly well. 542 00:37:22.476 --> 00:37:27.514 There are some areas of concern, advanced deterioration, 543 00:37:27.714 --> 00:37:31.251 and, uh, we're going to be assessing those going forward, 544 00:37:31.318 --> 00:37:34.121 uh, to try and get better predictions on how much longer 545 00:37:34.188 --> 00:37:35.722 the wreck will be with us. 546 00:37:39.092 --> 00:37:41.762 We wanted to take this moment to remember those 547 00:37:41.828 --> 00:37:45.465 that have, uh, perished the night that Titanic sank. 548 00:37:45.532 --> 00:37:48.702 As the expedition enters its final stages, 549 00:37:48.769 --> 00:37:51.772 the team is honoring Titanic's victims. 550 00:37:51.839 --> 00:37:54.508 And, um, we'll take a moment's silence. 551 00:38:11.358 --> 00:38:15.229 With the ceremony complete, the team preparesfor their next dive. 552 00:38:15.295 --> 00:38:17.631 It's a good opportunity to think 553 00:38:17.698 --> 00:38:20.501 about the site itself and to start planning the dive. 554 00:38:20.567 --> 00:38:25.839 I wanted to go beyond the dive, uh, to talk about a science program 555 00:38:25.906 --> 00:38:28.008 about the permanent conditions. 556 00:38:28.642 --> 00:38:33.113 The dive will help the team understand andpredict Titanic's future. 557 00:38:34.014 --> 00:38:36.650 They've taken a number of different types of metal, 558 00:38:36.750 --> 00:38:41.989 and then they've subjected them to different kinds of, uh, activity. 559 00:38:42.055 --> 00:38:44.858 Some of them have been subject to torsion, 560 00:38:44.958 --> 00:38:48.028 uh, some of them have been heat-treated with a welder, 561 00:38:48.095 --> 00:38:49.229 some have been riveted. 562 00:38:49.396 --> 00:38:52.065 Some... So, they're trying to replicate 563 00:38:52.132 --> 00:38:55.135 all the different kinds of metal that you might find on a ship 564 00:38:55.202 --> 00:38:57.204 and then subjecting it to the sort of forces 565 00:38:57.271 --> 00:38:59.306 that a ship in distress might suffer. 566 00:39:01.542 --> 00:39:04.845 The team wants to place the data platformnext to the wreck. 567 00:39:06.046 --> 00:39:09.616 It's a non-invasive but scientific way to record decline. 568 00:39:11.018 --> 00:39:14.755 The platform is made of steel, just like Titanic. 569 00:39:14.821 --> 00:39:17.858 The bacteria will start populating that steel source, 570 00:39:17.925 --> 00:39:21.895 so then we can bring that up after X number of years, 571 00:39:21.995 --> 00:39:23.830 it's considered a long-term experiment, 572 00:39:24.331 --> 00:39:27.868 and analyze it to, again, correlate that 573 00:39:27.935 --> 00:39:30.370 back to the deterioration rate of the wreck. 574 00:39:34.274 --> 00:39:37.477 You can see the very obvious manipulator arm, that's very powerful, 575 00:39:37.544 --> 00:39:40.848 but it can function all the way down to full ocean depth. 576 00:39:42.416 --> 00:39:44.451 The sub's manipulator arm will be used 577 00:39:44.518 --> 00:39:46.820 to place the steel platform on the sea floor, 578 00:39:47.521 --> 00:39:49.990 but doing this, 3 miles down, in the dark 579 00:39:50.090 --> 00:39:53.126 and with strong currents, won't be easy. 580 00:39:53.193 --> 00:39:55.229 It'll be a challenge, there's no doubt about it, 581 00:39:55.295 --> 00:39:57.497 but, um, I'm up for the challenge. 582 00:39:57.564 --> 00:40:00.133 - Good luck, guys. - Thanks, Victor. 583 00:40:03.003 --> 00:40:05.806 Kelvin is going to be operating the manipulator arm. 584 00:40:08.375 --> 00:40:10.811 And for this dive, Patrickis piloting the sub. 585 00:40:13.814 --> 00:40:16.450 - You got her? - Yep. Bring this bad boy down. 586 00:40:20.320 --> 00:40:23.056 The sub will be supported by a remotely controlled lander 587 00:40:23.156 --> 00:40:26.460 that will safely transport the data platform to thesea floor. 588 00:40:26.894 --> 00:40:29.263 You've got three swimmers below, 589 00:40:29.329 --> 00:40:31.064 you can start to pump and dive. 590 00:40:31.431 --> 00:40:33.867 Roger that. Turning pumps on now. Okay? 591 00:40:33.934 --> 00:40:35.402 - Yep. - Okay. 592 00:40:46.446 --> 00:40:50.150 Having arrived at the wreck, the team preparesto release the platform. 593 00:41:00.494 --> 00:41:04.531 But, at this depth, just the simplest of actions isfraught with difficulty. 594 00:41:10.070 --> 00:41:11.171 Looking good. 595 00:41:14.408 --> 00:41:18.245 The next task is to drop the platformin a safe place, 596 00:41:18.312 --> 00:41:22.015 as close to the wreck as possible sorusticles can latch on. 597 00:41:23.483 --> 00:41:25.419 Yeah, so bring it down to the ground here. 598 00:41:26.486 --> 00:41:27.721 Is that close enough? 599 00:41:29.456 --> 00:41:30.591 Looks pretty close. 600 00:41:31.859 --> 00:41:33.460 Here, let me get the arm going again. 601 00:41:43.103 --> 00:41:44.471 Yeah, yeah. Yep. 602 00:41:44.638 --> 00:41:47.407 How about that? 603 00:41:51.512 --> 00:41:54.248 When the platform is retrievedin years to come, 604 00:41:54.314 --> 00:41:57.150 on a new expedition, the rusticles captured 605 00:41:57.217 --> 00:41:59.753 will be vital in predicting Titanic's future. 606 00:42:05.425 --> 00:42:10.197 The team's mission is complete, and the first manned dives to Titanic 607 00:42:10.264 --> 00:42:13.467 in nearly 15 years have come to an end. 608 00:42:16.837 --> 00:42:18.906 Thanks very much, Frank, for getting us back. 609 00:42:24.244 --> 00:42:27.281 The expedition has led to the creation of the most accurate 610 00:42:27.347 --> 00:42:30.083 photogrammetry model of the wreck ever built. 611 00:42:42.496 --> 00:42:45.766 Titanic as no one has seen her before. 612 00:42:50.871 --> 00:42:55.142 And now she's beginning a new life as anartificial reef. 613 00:42:56.310 --> 00:42:59.847 Home to an abundant and diverse array ofmarine creatures. 614 00:43:01.415 --> 00:43:04.084 Honestly, there's more life on Titanic now 615 00:43:04.151 --> 00:43:07.020 than there was when she was floating on the surface. 616 00:43:09.423 --> 00:43:13.193 But, in time, as Titanic's decline continues, 617 00:43:13.260 --> 00:43:15.062 she will becomeunrecognizable. 618 00:43:15.729 --> 00:43:18.599 There's lots of varying opinions on Titanic. 619 00:43:18.665 --> 00:43:21.368 Is there any way thatwe can preserve it? 620 00:43:21.435 --> 00:43:27.107 But, I sometimes feel that people miss the point of the recycling aspect. 621 00:43:27.174 --> 00:43:31.311 This is a natural process. It was built through iron ore, 622 00:43:31.378 --> 00:43:34.882 uh, and the earth is reclaiming that iron ore from Titanic. 623 00:43:36.450 --> 00:43:39.319 It's a shipwreck that's returning to nature, 624 00:43:39.386 --> 00:43:43.757 but that doesn't mean that we're done exploring Titanic yet. 625 00:43:43.824 --> 00:43:46.927 This deterioration has now opened up new possibilities 626 00:43:46.994 --> 00:43:48.395 to learn more about the wreck. 627 00:43:51.498 --> 00:43:56.170 We went down there to look, to document, and to assess. 628 00:43:56.236 --> 00:44:00.274 The results of this expedition wildly exceeded our expectations.
