00:00:08,241 --> 00:00:12,078 ...a war time battle against an unlikely foe... 5 00:00:12,178 --> 00:00:16,750 The Navy was crippled by this strange bacon frying sound. 6 00:00:18,585 --> 00:00:20,887

is Orlando's most unusual attraction-- 15 00:00:49,282 --> 00:00:53,253 Skeletons Museum of Osteology. 16 00:00:55,522 --> 00:00:57,524 Dedicated to the study of bones, 17 00:00:57,624 --> 00:01:00,794 this collection of more than 500 real animal skeletons 18 00:01:00,894 --> 00:01:04,597 includes a two-toed sloth from South America, 19 00:01:04,698 --> 00:01:07,934 a Sumatran white rhinoceros, 20 00:01:08,034 --> 00:01:11,171 and the world's largest rodent, the capybara. 21 00:01:11,271 --> 00:01:14,574 But among these exotic creatures 22 00:01:14,674 --> 00:01:17,377 that walked on land is one specimen 23 00:01:17,477 --> 00:01:20,213 that plumbed the ocean's depths. 24 00:01:20,313 --> 00:01:22,649 The artifact is about 11 feet tall. 25 00:01:22,749 --> 00:01:26,252 It is off-white color made of calcified bone. 26 00:01:26,353 --> 00:01:29,122 It is smooth to the touch. 27 00:01:29,222 --> 00:01:33,827 This extraordinary skull recalls a mythical creature 28 00:01:33,927 --> 00:01:37,163 that tormented sailors on the high seas. 29 00:01:37,263 --> 00:01:39,399 This is a story about a sea captain, 30 00:01:39,499 --> 00:01:41,401 a legendary monster, 31 00:01:41,501 --> 00:01:43,770 and the debate left in its wake. 32 00:01:48,641 --> 00:01:51,611 August 6, 1848, 33 00:01:51,711 --> 00:01:54,080 in the South Atlantic. 34 00:01:54,180 --> 00:01:57,417 Captain Peter McQuhae is the commander of the HMS Daedalus . 35 00:01:57,517 --> 00:02:00,153 McQuhae was a sea captain that had 36 00:02:00,253 --> 00:02:03,456 an impeccable reputation-- he ran a very tight ship, 37 00:02:03,556 --> 00:02:06,026 and he was a no-nonsense type of guy. 38 00:02:08,695 --> 00:02:11,297 McQuhae's ship is en route from the East Indies 39 00:02:11,398 --> 00:02:13,533 to its home port in England. 40 00:02:13,633 --> 00:02:16,503 Three hundred miles off the southern coast of Africa, 41 00:02:16,603 --> 00:02:19,172 the captain is alerted to something off 42 00:02:19,272 --> 00:02:21,541 the vessel's starboard side. 43 00:02:23,677 --> 00:02:25,812 There in the water is a massive creature 44 00:02:25,912 --> 00:02:28,148 unlike anything he has ever seen. 45 00:02:28,248 --> 00:02:30,417 The leviathan 46 00:02:30,517 --> 00:02:32,519 is more than 60 feet long, 47 00:02:32,619 --> 00:02:36,022 has a slender, serpentine body, and is dark brown in color, 48 00:02:36,122 --> 00:02:39,225 but the most frightening characteristic of all 49 00:02:39,325 --> 00:02:42,295 is the creature's massive head, 50 00:02:42,395 --> 00:02:46,032 which protrudes from the water with its jaws agape. 51 00:02:46,132 --> 00:02:48,868 Captain McQuhae had seen everything... 52 00:02:48,968 --> 00:02:52,038 but he hadn't seen this. 53 00:02:52,138 --> 00:02:55,642 For centuries, sailors have told stories 54 00:02:55,742 --> 00:02:59,245 of monstrous creatures that lurk in the depths of the ocean. 55 00:02:59,346 --> 00:03:02,215 Some have even been said 56 00:03:02,315 --> 00:03:05,752 to sink entire ships and devour their crews. 57 00:03:05,852 --> 00:03:08,588 Like many others, Captain McQuhae has always 58 00:03:08,688 --> 00:03:12,192 assumed such tales to be little more than myths, 59 00:03:12,292 --> 00:03:16,096 but now, with just such a monster alongside his ship, 60 00:03:16,196 --> 00:03:18,798 the legends seem all too real. 61 00:03:18,898 --> 00:03:21,267 He had heard about these stories, 62 00:03:21,368 --> 00:03:23,703 but he had never run into a creature like this before. 63 00:03:23,803 --> 00:03:27,407 Then, as suddenly as it appeared, 64 00:03:27,507 --> 00:03:30,410 the creature vanishes beneath the waves. 65 00:03:30,510 --> 00:03:33,913 When the Daedalus docks in England, 66 00:03:34,014 --> 00:03:36,549 the captain and crew share the story 67 00:03:36,649 --> 00:03:38,985 of their bizarre encounter. 68 00:03:39,085 --> 00:03:42,856 And soon, all of London buzzes with speculation. 69 00:03:42,956 --> 00:03:45,892 The news was an absolute sensation. 70 00:03:45,992 --> 00:03:49,929 The creature becomes known as the Daedalus Sea Serpent. 71 00:03:50,030 --> 00:03:52,866 But as public fascination grows, 72 00:03:52,966 --> 00:03:55,935 some doubt the veracity of McQuhae's tale. 73 00:03:58,738 --> 00:04:01,141 A fellow ship captain claims the beast was nothing more 74 00:04:01,241 --> 00:04:03,977 than an enormous clump of seaweed. 75 00:04:04,077 --> 00:04:06,946 but McQuhae insists that what he saw 76 00:04:07,047 --> 00:04:09,449 was no tangle of plants. 77 00:04:09,549 --> 00:04:12,152 A seaweed didn't have a defined body, 78 00:04:12,252 --> 00:04:14,554 a head, and eyes. 79 00:04:14,654 --> 00:04:17,957 An English biologist suggests that what the men saw 80 00:04:18,058 --> 00:04:20,827 was just a particularly large elephant seal, 81 00:04:20,927 --> 00:04:23,997 a creature which has been known to reach 15 feet in length, 82 00:04:24,097 --> 00:04:27,400 but McQuhae swears that what he and his men witnessed 83 00:04:27,500 --> 00:04:30,570 was much larger than a big seal. 84 00:04:30,670 --> 00:04:33,640 He knew by the sheer size of the sea creature 85 00:04:33,740 --> 00:04:36,476 that there's no way it could have been an elephant seal. 86 00:04:39,346 --> 00:04:41,281 As the story spreads, 87 00:04:41,381 --> 00:04:43,416 artists and illustrators create their own 88 00:04:43,516 --> 00:04:46,553 terrifying depictions of the monstrous serpent, 89 00:04:46,653 --> 00:04:49,389 and McQuhae goes to his grave insisting 90 00:04:49,489 --> 00:04:52,759 that he and his crew had indeed encountered a sea monster. 91 00:04:52,859 --> 00:04:56,830 It remains one of the strangest mysteries of the high seas, 92 00:04:56,930 --> 00:05:00,900 but more than 160 years after the sighting, 93 00:05:01,001 --> 00:05:03,903 new information emerges that may finally 94 00:05:04,004 --> 00:05:05,939 shed light on the case. 95 00:05:06,039 --> 00:05:07,974 A distant connection was about to change 96 00:05:08,074 --> 00:05:10,276 everything we knew about this monster. 97 00:05:12,479 --> 00:05:14,514 It's 2015 in Chicago. 98 00:05:14,614 --> 00:05:17,917 Evolutionary biologist, Dr. Gary J.

00:12:41,828 have been rendered useless 245 00:12:41,928 --> 00:12:45,565 by the popping sounds produced by tiny pistol shrimp 246 00:12:45,665 --> 00:12:48,234 all clapping their claws in unison. 247 00:12:48,335 --> 00:12:52,005 The result is that the Navy can't detect enemy subs, 248 00:12:52,105 --> 00:12:55,275 leaving American sailors vulnerable to attack. 249 00:12:55,375 --> 00:13:01,081 So is the U.S. Navy about to be defeated by shrimp? 250 00:13:01,181 --> 00:13:04,217 Tasked with solving the prawny problem 251 00:13:04,317 --> 00:13:07,454 is marine biologist Dr. Martin Johnson. 252 00:13:07,554 --> 00:13:09,756 Johnson knows the Navy can't kill off 253 00:13:09,856 --> 00:13:11,691 these colonies of shrimp, 254 00:13:11,791 --> 00:13:15,362 but the Navy could use the situation

00:13:22,902 So if the shrimp affected the U.S. sonar equipment, 258 00:13:23,003 --> 00:13:25,305 it was definitely gonna affect the enemy's. 259 00:13:25,405 --> 00:13:27,173 WILDMAN: Johnson reasons 260 00:13:27,273 --> 00:13:31,277 that if U.S. subs hide near colonies of pistol shrimp, 261 00:13:31,378 --> 00:13:33,747 the Japanese will never be able to detect them 262 00:13:33,847 --> 00:13:35,482 through the noise. 263 00:13:35,582 --> 00:13:37,384 MALLOY: Dr. Johnson recommended 264 00:13:37,484 --> 00:13:39,386 they use the shrimp as camouflage 265 00:13:39,486 --> 00:13:41,121 against the Japanese sonar. 266 00:13:41,221 --> 00:13:44,290 The Navy thought Johnson's idea was absolutely brilliant. 267 00:13:48,995 --> 00:13:50,096 WILDMAN: With Johnson's help, 268 00:13:50,196 --> 00:13:53,133 the Navy distributes maps of pistol shrimp colonies 269 00:13:53,233 --> 00:13:55,702 to submarines throughout the Pacific. 270 00:13:55,802 --> 00:13:59,272 These maps provide a network of acoustic hiding places 271 00:13:59,372 --> 00:14:02,475 all along Japanese supply routes. 272 00:14:05,311 --> 00:14:09,082 By camouflaging their fleet in these underwater havens, 273 00:14:09,182 --> 00:14:12,786 the U.S. Navy gains a decisive advantage in the war. 274 00:14:12,886 --> 00:14:16,423 MALLOY: With all the technology that the U.S. had in World War II, 275 00:14:16,523

among these extraordinary creatures of the deep 297 00:15:34,868 --> 00:15:38,872 is a tiny specimen with the strangest story to tell. 298 00:15:38,972 --> 00:15:41,975 The artifact is about 7 and 1/2 inches long, 299 00:15:42,075 --> 00:15:44,611 and it weighs about 1/4 of a pound. 300 00:15:44,711 --> 00:15:46,446 It is brownish-yellow. 301 00:15:46,546 --> 00:15:48,948 It was preserved in a glass jar 302 00:15:49,049 --> 00:15:52,052 with a white plastic lid. 303 00:15:52,152 --> 00:15:55,922 This organism played a starring role 304 00:15:56,022 --> 00:15:58,725 in an underwater enigma that bamboozled 305 00:15:58,825 --> 00:16:00,994 the world of science. 306 00:16:01,094 --> 00:16:03,930 This is a story of passion, discovery, 307 00:16:04,030 --> 00:16:06,733 and unexplored mysteries of the deep ocean. 308 00:16:11,338 --> 00:16:14,708 Japan, 2012. 309 00:16:14,808 --> 00:16:18,411 Yoji Okata is an avid scuba diver 310 00:16:18,511 --> 00:16:21,247 and successful underwater photographer. 311 00:16:21,348 --> 00:16:24,517 Yoji was an adventurous person with a passion 312 00:16:24,617 --> 00:16:26,920 for the natural world. 313 00:16:28,955 --> 00:16:30,357 One day in September, 314 00:16:30,457 --> 00:16:32,759 Yoji is diving off the southern coast of Japan 315 00:16:32,859 --> 00:16:37,030 when he sees something unusual on the seabed. 316 00:16:40,166 --> 00:16:41,901 Etched into the sand below him 317 00:16:42,002 --> 00:16:44,237 is an intricate design. 318 00:16:44,337 --> 00:16:47,674 Yoji observed a strange, circular pattern 319 00:16:47,774 --> 00:16:51,644 about six feet wide with sort of sand ridges and hills 320 00:16:51,745 --> 00:16:53,980 throughout the circle. 321 00:16:54,080 --> 00:16:56,750 In his years of underwater photography, 322 00:16:56,850 --> 00:16:59,819 Yoji had never seen anything like this. 323 00:17:02,155 --> 00:17:04,357 The pattern seems too perfect to have 324 00:17:04,457 --> 00:17:07,327 any natural explanation. 325 00:17:07,427 --> 00:17:09,863 He was determined to try and figure out 326 00:17:09,963 --> 00:17:13,233 what actually was the cause of these underwater circles. 327 00:17:17,070 --> 00:17:18,438 Later, when he examines his photos, 328 00:17:18,538 --> 00:17:21,841 Yoji discovers that he is not the first 329 00:17:21,941 --> 00:17:24,978 to come across these complex underwater designs. 330 00:17:25,078 --> 00:17:29,015 These undersea circles were first documented by divers 331 00:17:29,115 --> 00:17:32,118 in the Pacific Ocean in 1995, 332 00:17:32,218 --> 00:17:35,622 but since then, their origin has remained a mystery. 333 00:17:35,722 --> 00:17:40,026 Some speculate that they're made by ocean currents 334 00:17:40,126 --> 00:17:42,829 forming patterns in the seabed. 335 00:17:42,929 --> 00:17:46,533 But this made no sense to anyone that understood physics of water. 336 00:17:46,633 --> 00:17:50,870 Sand ripples ought to occur in a typical linear fashion. 337 00:17:50,970 --> 00:17:53,606 This was a circle. 338 00:17:55,909 --> 00:17:58,111 Others believe the designs are merely a hoax 339 00:17:58,211 --> 00:18:00,847 created by mischievous divers, 340 00:18:00,947 --> 00:18:03,750 but this hypothesis doesn't hold water, either, 341 00:18:03,850 --> 00:18:06,786 as the circles have been found across a wide swath 342 00:18:06,886 --> 00:18:09,289 of the Pacific Ocean. 343 00:18:09,389 --> 00:18:11,758 No single diver or group of divers could possibly 344 00:18:11,858 --> 00:18:14,094 have made all of these strange formations 345 00:18:14,194 --> 00:18:17,530 on the bottom of the ocean in all of these different places. 346 00:18:20,033 --> 00:18:22,769 With no obvious explanation at hand, 347 00:18:22,869 --> 00:18:25,905 some note that these strange patterns on the seabed 348 00:18:26,006 --> 00:18:29,009 bear a striking resemblance to another bizarre, 349 00:18:29,109 --> 00:18:31,344 land-based phenomenon-- 350 00:18:31,444 --> 00:18:33,980 crop circles. 351 00:18:34,080 --> 00:18:36,416 In the 1970s and '80s, 352 00:18:36,516 --> 00:18:40,220 large, unexplained circular patterns began appearing 353 00:18:40,320 --> 00:18:43,023 in corn fields in the United States and Europe, 354 00:18:43,123 --> 00:18:45,825 leading many to suggest that the crop circles 355 00:18:45,925 --> 00:18:48,628 were the work of extraterrestrials. 356 00:18:48,728 --> 00:18:50,964 And if that theory is correct, 357 00:18:51,064 --> 00:18:54,000 then perhaps who, or whatever, made the crop circles 358 00:18:54,100 --> 00:18:57,837 also created these intricate patterns on the ocean floor. 359 00:19:01,207 --> 00:19:03,743 But none of these theories satisfy Yoji. 360 00:19:03,843 --> 00:19:06,646 Yoji did not feel that any of those explanations 361 00:19:06,746 --> 00:19:10,450 were rational, but he wanted to know 362 00:19:10,550 --> 00:19:13,920 what was causing these unusual, crop-like 363 00:19:14,020 --> 00:19:16,756 circular formations in the sand. 364 00:19:16,856 --> 00:19:18,858 So what's really behind 365 00:19:18,958 --> 00:19:21,594 these curious deep sea creations? 366 00:19:27,934 --> 00:19:30,003 Underwater photographer, Yoji Okata, 367 00:19:30,103 --> 00:19:32,906 has discovered something unusual while diving 368 00:19:33,006 --> 00:19:36,443 off the coast of Japan-- large, intricate patterns 369 00:19:36,543 --> 00:19:38,611 etched into the sand on the ocean floor. 370 00:19:38,712 --> 00:19:41,181 So what or who is responsible 371 00:19:41,281 --> 00:19:43,216 for these deep sea designs? 372 00:19:46,419 --> 00:19:48,688 To crack the enigma, Yoji Okata 373 00:19:48,788 --> 00:19:51,424 returns to the deep, along with an investigative 374 00:19:51,524 --> 00:19:53,193 team of divers. 375 00:19:55,462 --> 00:19:57,464 After days of searching, they find 376 00:19:57,564 --> 00:20:00,166 another ornate circular design. 377 00:20:00,266 --> 00:20:03,169 It's then that the divers see something moving 378 00:20:03,269 --> 00:20:05,405 in the middle of the circle-- 379 00:20:07,907 --> 00:20:10,410 a tiny fish. 380 00:20:10,510 --> 00:20:14,114 The divers observe the small pufferfish flapping 381 00:20:14,214 --> 00:20:17,050 its fins frantically as it swam back and forth. 382 00:20:17,150 --> 00:20:19,686 The team watches 383 00:20:19,786 --> 00:20:22,655 as the fish uses its fins to create 384 00:20:22,756 --> 00:20:25,625 a circular pattern on the ocean floor. 385 00:20:25,725 --> 00:20:28,728 It didn't take long for the divers to recognize 386 00:20:28,828 --> 00:20:31,364 that the artist of these strange sand formations 387 00:20:31,464 --> 00:20:33,833 was, in fact, a small pufferfish. 388 00:20:33,933 --> 00:20:36,970 The creature is identified as a member of 389 00:20:37,070 --> 00:20:40,674 a newly discovered species called the white spotted pufferfish. 390 00:20:44,377 --> 00:20:46,279 But the question remains-- 391 00:20:46,379 --> 00:20:48,515 why do they make these intricate patterns? 392 00:20:48,615 --> 00:20:51,184 After careful observation, 393 00:20:51,284 --> 00:20:53,720 scientists conclude that the work is done 394 00:20:53,820 --> 00:20:57,757 by the male of the species as an elaborate courtship ritual. 395 00:21:00,193 --> 00:21:02,495 The sand formations attracted females, 396 00:21:02,595 --> 00:21:04,597 who swam down the grooves, 397 00:21:04,698 --> 00:21:07,567 where the male was waiting-- the females deposited 398 00:21:07,667 --> 00:21:09,903 their eggs, and the male fertilized them, 399 00:21:10,003 --> 00:21:12,539 and then the male protected those eggs until they hatched. 400 00:21:15,909 --> 00:21:18,278 Yoji Okata and his team are the first to witness 401 00:21:18,378 --> 00:21:20,880 one of the most unusual mating rituals 402 00:21:20,980 --> 00:21:23,016 in the natural world. 403 00:21:23,116 --> 00:21:25,752 Yoji was elated that he finally had discovered 404 00:21:25,852 --> 00:21:29,356 the culprit, the artist, of these strange sand formations. 405 00:21:32,926 --> 00:21:35,895 Today, this pufferfish, like the one responsible 406 00:21:35,995 --> 00:21:39,299 for making these underwater creations, is on display 407 00:21:39,399 --> 00:21:42,002 at the Scripps Institution of Oceanography 408 00:21:42,102 --> 00:21:44,371 in San Diego, California. 409 00:21:44,471 --> 00:21:46,906 It recalls a remarkable quest 410 00:21:47,007 --> 00:21:50,744 to reveal the puzzling patterns of ocean life. 411 00:21:54,948 --> 00:21:57,650 Wooden Polynesian effigies, 412 00:21:57,751 --> 00:22:01,121 hand-carved Native American masks... 413 00:22:01,221 --> 00:22:05,525 and the 10,000 year old bones of the Mastodon. 414 00:22:05,625 --> 00:22:09,229 These and other wonders of the Pacific northwest 415 00:22:09,329 --> 00:22:11,231 are on display at the Burke Museum 416 00:22:11,331 --> 00:22:12,799 of Natural History and Culture 417 00:22:12,899 --> 00:22:14,467 in Seattle, Washington 418 00:22:18,638 --> 00:22:20,940 But amidst these earthly relics is one item 419 00:22:21,041 --> 00:22:24,144 that has no place on dry land. 420 00:22:24,244 --> 00:22:27,614 MASLENIKOV: It is about 6 inches long, about 3 1/2 inches wide. 421 00:22:27,714 --> 00:22:30,316 There is a rod coming out of the forehead 422 00:22:30,417 --> 00:22:34,421 with this glowing object at the end of it. 423 00:22:34,521 --> 00:22:37,290 And it has some very large teeth. 424 00:22:40,160 --> 00:22:42,829 WILDMAN: These frightening creatures once roamed unseen 425 00:22:42,929 --> 00:22:45,765 in the darkest depths of the ocean 426 00:22:45,865 --> 00:22:47,801 until they were brought into the light 427 00:22:47,901 --> 00:22:51,738 by one of the most incredible and dangerous expeditions 428 00:22:51,838 --> 00:22:54,441 the world has ever witnessed. 429 00:22:54,541 --> 00:22:56,976 This story tells us about the amazing impossibilities 430 00:22:57,077 --> 00:22:58,978 when we explore the unknown. 431 00:23:02,148 --> 00:23:05,485 WILDMAN: 1925 -- Bermuda. 432 00:23:05,585 --> 00:23:08,388 48-year-old explorer William Beebe is 433 00:23:08,488 --> 00:23:12,158 one of the world's most highly respected biologists. 434 00:23:12,258 --> 00:23:14,160 Throughout his career, he has discovered 435 00:23:14,260 --> 00:23:18,131 countless rare and exotic bird species. 436 00:23:18,231 --> 00:23:19,966 But now the scientist is planning 437 00:23:20,066 --> 00:23:22,635 his greatest adventure yet. 438 00:23:22,736 --> 00:23:24,971 He wants to unlock the secrets held 439 00:23:25,071 --> 00:23:28,475 in the darkest depths of the earth's oceans. 440 00:23:28,575 --> 00:23:31,578 The ocean is this vast, undiscovered frontier. 441 00:23:31,678 --> 00:23:33,480 And for Beebe, here was the chance 442 00:23:33,580 --> 00:23:38,251 to really make his mark in a whole new way. 443 00:23:38,351 --> 00:23:41,421 WILDMAN: But that's easier said than done. 444 00:23:41,521 --> 00:23:45,191 The most advanced diving suits of the day 445 00:23:45,291 --> 00:23:48,228 can only reach a depth of 500 feet. 446 00:23:48,328 --> 00:23:51,197 Anything below that, and the diver inside 447 00:23:51,297 --> 00:23:53,299 would be crushed by the pressure of the water. 448 00:23:53,400 --> 00:23:56,302 But Beebe is undeterred. 449 00:23:56,403 --> 00:23:58,672 MASLENIKOV: He wanted to get deeper and deeper. 450 00:23:58,772 --> 00:24:00,306 So Beebe decides that the only way 451 00:24:00,407 --> 00:24:03,410 he's going to get down there is if he builds a vessel. 452 00:24:03,510 --> 00:24:04,978 WILDMAN: So Beebe teams up 453 00:24:05,078 --> 00:24:08,048 with an engineer named Otis Barton. 454 00:24:08,148 --> 00:24:10,950 Barton is this young engineering student. 455 00:24:11,051 --> 00:24:14,454 For him, it was all about going down as deep as they could. 456 00:24:14,554 --> 00:24:16,489 WILDMAN: Together, they come up with a simple 457 00:24:16,589 --> 00:24:18,992 yet brilliant design. 458 00:24:19,092 --> 00:24:20,894 MASLENIKOV: They knew that it had to be a sphere 459 00:24:20,994 --> 00:24:25,732 because a sphere will distribute the pressure evenly. 460 00:24:25,832 --> 00:24:27,834 WILDMAN: For years, the men worked tirelessly 461 00:24:27,934 --> 00:24:30,904 to build their vessel. 462 00:24:31,004 --> 00:24:34,808 In 1930, it's finally ready. 463 00:24:34,908 --> 00:24:38,445 The craft is made of more than two tons of cast steel 464 00:24:38,545 --> 00:24:41,114 and features two solid-quartz windows, 465 00:24:41,214 --> 00:24:46,419 oxygen tanks, and a spotlight to illuminate the murky water. 466 00:24:46,519 --> 00:24:50,223 It's been carefully welded together so it won't leak. 467 00:24:50,323 --> 00:24:54,461 And it's only opening is a 400-pound door. 468 00:24:54,561 --> 00:24:56,429 If all goes well, it should be able 469 00:24:56,529 --> 00:25:00,433 to withstand depths of up to 4,000 feet. 470 00:25:00,533 --> 00:25:03,003 Beebe and Barton name it the bathysphere, 471 00:25:03,103 --> 00:25:05,071 Greek for "deep sphere." 472 00:25:05,171 --> 00:25:07,073 It was surprisingly small. 473 00:25:07,173 --> 00:25:09,676 It was only 4 1/2 feet across. 474 00:25:13,079 --> 00:25:16,349 WILDMAN: On June 6, 10 miles off the coast of Bermuda, 475 00:25:16,449 --> 00:25:20,320 Beebe and Barton squeeze into the bathysphere. 476 00:25:20,420 --> 00:25:22,589 The vessel is lowered into the ocean 477 00:25:22,689 --> 00:25:26,559 via a cable attached to a barge. 478 00:25:26,659 --> 00:25:29,262 A telephone line keeps them in constant communication 479 00:25:29,362 --> 00:25:31,131 with the ship's crew. 480 00:25:33,333 --> 00:25:36,036 They were so excited and so scared. 481 00:25:36,136 --> 00:25:39,673 They were alone in this steel sphere 482 00:25:39,773 --> 00:25:43,209 lowered where no one had ever been. 483 00:25:43,309 --> 00:25:44,778 WILDMAN: Inside the bathysphere, 484 00:25:44,878 --> 00:25:47,847 Beebe and Barton begin their descent. 485 00:25:47,947 --> 00:25:53,053 To their relief, the design appears to be working perfectly. 486 00:25:53,153 --> 00:25:55,522 But when they reach 300 feet, 487 00:25:55,622 --> 00:25:59,092 something goes terribly wrong. 488 00:25:59,192 --> 00:26:01,828 The door suddenly starts to leak. 489 00:26:04,230 --> 00:26:07,901 Trapped inside this sphere, the men could drown. 490 00:26:08,001 --> 00:26:11,705 If this situation is not solved, they will die. 491 00:26:16,743 --> 00:26:19,713 It's 1930 off the coast of Bermuda. 492 00:26:19,813 --> 00:26:22,916 Explorers William Beebe and Otis Barton are attempting 493 00:26:23,016 --> 00:26:25,352 an unprecedented journey beneath the sea 494 00:26:25,452 --> 00:26:27,354 in a new type of submersible. 495 00:26:27,454 --> 00:26:30,523 But when they reach the depth of 300 feet, 496 00:26:30,623 --> 00:26:32,258 disaster strikes. 497 00:26:32,359 --> 00:26:35,362 Water is suddenly seeping into the craft. 498 00:26:35,462 --> 00:26:38,865 So, can they survive this deadly breach? 499 00:26:41,668 --> 00:26:43,870 As the water pours in from the door, 500 00:26:43,970 --> 00:26:47,407 Beebe proposes an unbelievable solution. 501 00:26:47,507 --> 00:26:50,377 Beebe decides that, rather than go back up to surface 502 00:26:50,477 --> 00:26:55,682 and try and solve the problem, they should go down and fast. 503 00:26:55,782 --> 00:26:57,484 He believes that at a greater depth, 504 00:26:57,584 --> 00:26:59,919 the increased water pressure will actually 505 00:27:00,020 --> 00:27:03,890 push the door tight enough to stop the leak. 506 00:27:03,990 --> 00:27:07,894 It's a bit counterintuitive. You'd think you need to go up. 507 00:27:07,994 --> 00:27:10,897 But if you go down, the pressure will actually 508 00:27:10,997 --> 00:27:13,733 then compress where that problem is 509 00:27:13,833 --> 00:27:17,303 and seal the crack for you. 510 00:27:17,404 --> 00:27:20,106 WILDMAN: Beebe and Barton wait with baited breath 511 00:27:20,206 --> 00:27:23,443 as they descend deeper into the ocean. 512 00:27:23,543 --> 00:27:27,814 To their relief, the leak stops. 513 00:27:27,914 --> 00:27:29,349 With the crisis averted, 514 00:27:29,449 --> 00:27:33,453 Beebe and Barton are able to reach a record depth. 515 00:27:33,553 --> 00:27:35,522 MASLENIKOV: They made it down to 800 feet. 516 00:27:35,622 --> 00:27:37,257 And that was the deepest 517 00:27:37,357 --> 00:27:40,894 that any human had ever been alive. 518 00:27:40,994 --> 00:27:44,130 WILDMAN: The explorers spend an hour below the surface 519 00:27:44,230 --> 00:27:46,800 before being pulled safely back up to the ship. 520 00:27:49,969 --> 00:27:53,206 Over the next several years, Beebe and Barton complete 521 00:27:53,306 --> 00:27:56,676 a series of deeper and deeper dives. 522 00:27:56,776 --> 00:27:59,145 They eventually reach the staggering depth 523 00:27:59,245 --> 00:28:02,282 of 3,028 feet. 524 00:28:02,382 --> 00:28:05,118 Far beneath the surface, Beebe is able to observe 525 00:28:05,218 --> 00:28:08,621 deep-sea creatures in their natural environment, 526 00:28:08,722 --> 00:28:11,358 including the extraordinary anglerfish. 527 00:28:11,458 --> 00:28:15,862 He was so excited when he looked out that window 528 00:28:15,962 --> 00:28:18,732 and, for the first time, saw the anglerfish. 529 00:28:23,236 --> 00:28:25,805 WILDMAN: Today, this anglerfish remains preserved 530 00:28:25,905 --> 00:28:29,009 at the Burke Museum of Natural History in Seattle. 531 00:28:29,109 --> 00:28:32,078 It recalls a historic journey beneath the sea 532 00:28:32,178 --> 00:28:36,182 and the two daring men who exposed a brand-new world. 533 00:28:40,387 --> 00:28:42,355 New Bedford, Massachusetts. 534 00:28:42,455 --> 00:28:44,958 In 1841, author Herman Melville 535 00:28:45,058 --> 00:28:47,227 sailed from this port city on the expedition 536 00:28:47,327 --> 00:28:49,629 that inspired his great American novel, 537 00:28:49,729 --> 00:28:51,398 Moby-Dick . 538 00:28:51,498 --> 00:28:54,034 Today, the area's nautical history is showcased 539 00:28:54,134 --> 00:28:56,302 at the New Bedford Whaling Museum. 540 00:29:00,974 --> 00:29:03,109 Here, visitors can view scrimshaw carvings 541 00:29:03,209 --> 00:29:05,412 from the 18th century, 542 00:29:05,512 --> 00:29:08,214 the skeleton of a baby blue whale, 543 00:29:08,314 --> 00:29:10,216 and the world's largest model whaling ship. 544 00:29:12,719 --> 00:29:14,754 But one item here looks like it belongs 545 00:29:14,854 --> 00:29:18,958 not in a maritime museum but in a science fiction movie. 546 00:29:19,059 --> 00:29:21,428 It's a metallic cylinder. 547 00:29:21,528 --> 00:29:23,797 It's very thin. 548 00:29:23,897 --> 00:29:26,266 It's about two and a half feet high, 549 00:29:26,366 --> 00:29:28,535 and it almost looks like a big bullet. 550 00:29:31,137 --> 00:29:34,207 This strange instrument recalls a wondrous tale 551 00:29:34,307 --> 00:29:37,644 of adventure, exploration, and creatures from the deep. 552 00:29:37,744 --> 00:29:41,348 This is a story of the incredible possibilities 553 00:29:41,448 --> 00:29:43,350 beneath the Earth's oceans. 554 00:29:47,520 --> 00:29:50,323 1997, Newport, Oregon. 555 00:29:50,423 --> 00:29:53,259 Dr. Christopher Fox is a veteran researcher 556 00:29:53,360 --> 00:29:56,329 for the National Oceanic and Atmospheric Administration, 557 00:29:56,429 --> 00:29:58,431 or NOAA. 558 00:29:58,531 --> 00:30:01,801 Their role is to monitor and do scientific study 559 00:30:01,901 --> 00:30:04,604 of the oceans and atmosphere. 560 00:30:04,704 --> 00:30:07,640 One of NOAA's most powerful tools 561 00:30:07,741 --> 00:30:10,810 is a scientific instrument called the hydrophone. 562 00:30:10,910 --> 00:30:14,514 The listening device, like this one in the collection 563 00:30:14,614 --> 00:30:16,816 of the New Bedford Whaling Museum, 564 00:30:16,916 --> 00:30:19,686 is a microphone designed for recording or monitoring 565 00:30:19,786 --> 00:30:21,921 sound underwater. 566 00:30:22,022 --> 00:30:24,224 Most of the time, Fox and his fellow scientists 567 00:30:24,324 --> 00:30:26,960 pick up sounds of sea life or ships. 568 00:30:27,060 --> 00:30:29,863 But one day, 569 00:30:29,963 --> 00:30:32,132 they hear something louder and stranger 570 00:30:32,232 --> 00:30:34,334 than anything they've heard before. 571 00:30:38,071 --> 00:30:40,040 They couldn't figure out what these sounds were. 572 00:30:40,140 --> 00:30:42,042 It had not previously been recorded. 573 00:30:42,142 --> 00:30:44,310 It actually sounded like a "bloop!" 574 00:30:47,914 --> 00:30:51,818 Fittingly, the scientists nickname the unusual sound 575 00:30:51,918 --> 00:30:54,888 the Bloop, and according to their data, 576 00:30:54,988 --> 00:30:58,458 it appears to originate from over 3,000 miles away. 577 00:30:58,558 --> 00:31:01,161 Fox is astonished. 578 00:31:01,261 --> 00:31:03,963 For a sound to travel such a distance, 579 00:31:04,064 --> 00:31:06,933 its source must be deafeningly loud. 580 00:31:07,033 --> 00:31:09,869 When you find something so abnormal, 581 00:31:09,969 --> 00:31:13,239 it really gave people a lot of pause of what that 582 00:31:13,340 --> 00:31:15,408 could actually be. 583 00:31:15,508 --> 00:31:18,645 The short, seemingly random sound pattern 584 00:31:18,745 --> 00:31:22,582 bears no similarities to the long, steady hum of submarines 585 00:31:22,682 --> 00:31:25,251 or other man-made machines, 586 00:31:25,352 --> 00:31:28,088 and it doesn't match the pattern that would be expected 587 00:31:28,188 --> 00:31:30,423 from an underwater earthquake, volcano, 588 00:31:30,523 --> 00:31:33,059 or other geological phenomena. 589 00:31:33,159 --> 00:31:35,762 It was unknown where the sound was coming from. 590 00:31:38,665 --> 00:31:41,434 With these simple explanations ruled out, 591 00:31:41,534 --> 00:31:45,105 a more remote, even outlandish possibility, emerges-- 592 00:31:45,205 --> 00:31:47,741 that the sound could be emanating 593 00:31:47,841 --> 00:31:50,443 from some kind of unknown sea creature. 594 00:31:52,679 --> 00:31:54,848 We know more about the surface of Mars and the moon 595 00:31:54,948 --> 00:31:57,217 than we know about the floors of the sea. 596 00:31:57,317 --> 00:32:00,253 There is life down there, and we don't necessarily 597 00:32:00,353 --> 00:32:03,056 know what it is. 598 00:32:03,156 --> 00:32:05,925 But for a marine animal to make a noise 599 00:32:06,026 --> 00:32:09,596 as powerful as the Bloop, it would have to be gargantuan in size. 600 00:32:09,696 --> 00:32:11,798 A blue whale, 601 00:32:11,898 --> 00:32:14,234 the largest known living creature on the planet, 602 00:32:14,334 --> 00:32:17,771 emits a call that's more deafening than a jet plane. 603 00:32:17,871 --> 00:32:21,274 And based on his calculations, 604 00:32:21,374 --> 00:32:25,211 Fox estimates that the Bloop is three times as loud. 605 00:32:25,311 --> 00:32:27,614 If we were to consider that this monster's 606 00:32:27,714 --> 00:32:30,083 about three times the size of a blue whale, 607 00:32:30,183 --> 00:32:33,620 it probably would've been the length of about eight to nine school buses. 608 00:32:33,720 --> 00:32:36,990 So is this thunderous sound really coming 609 00:32:37,090 --> 00:32:39,359 from a giant, undiscovered sea creature? 610 00:32:45,565 --> 00:32:47,467 It's 1997. 611 00:32:47,567 --> 00:32:50,103 Dr. Christopher Fox and a team of researchers 612 00:32:50,203 --> 00:32:53,440 have recorded an underwater sound in the Pacific Ocean. 613 00:32:53,540 --> 00:32:56,142 They've named it the Bloop. 614 00:32:56,242 --> 00:32:59,913 The sound is one of the loudest and most powerful ever recorded, 615 00:33:00,013 --> 00:33:02,816 leading some to suspect the source may be 616 00:33:02,916 --> 00:33:05,885 a giant marine creature that's never been seen before. 617 00:33:05,985 --> 00:33:09,789 So is there some massive, mysterious beast 618 00:33:09,889 --> 00:33:12,659 lurking in the deep? 619 00:33:12,759 --> 00:33:17,664 Fox and his fellow researchers continue to monitor the Bloop for weeks, 620 00:33:17,764 --> 00:33:21,568 but they cannot determine what is making the thunderous sound. 621 00:33:21,668 --> 00:33:24,571 Then, suddenly, 622 00:33:24,671 --> 00:33:27,040 it stops. 623 00:33:27,140 --> 00:33:29,476 And now that it's gone, it seems that finding the source 624 00:33:29,576 --> 00:33:32,312 of the strange sound will be impossible. 625 00:33:32,412 --> 00:33:36,316 No one hears the Bloop for years. 626 00:33:39,185 --> 00:33:41,187 Then, in 2008, 627 00:33:41,287 --> 00:33:44,657 scientists in the Antarctic are monitoring acoustic activity 628 00:33:44,758 --> 00:33:48,461 when they pick up the same unusually powerful sound, 629 00:33:48,561 --> 00:33:51,398 and this time, whatever is making it 630 00:33:51,498 --> 00:33:54,200 appears to be close by. 631 00:33:54,300 --> 00:33:57,170 This phenomenon happened again, and it happened to be recorded 632 00:33:57,270 --> 00:33:59,739 closer to their source. 633 00:33:59,839 --> 00:34:02,409 The researchers methodically search the region, 634 00:34:02,509 --> 00:34:05,712 yet they find no trace of a large marine creature. 635 00:34:05,812 --> 00:34:09,449 But they do notice an interesting natural phenomenon 636 00:34:09,549 --> 00:34:13,119 that might solve the mystery once and for all. 637 00:34:13,219 --> 00:34:17,123 They witness large glaciers moving and breaking apart, 638 00:34:17,223 --> 00:34:20,627 a geologic process known as cavving. 639 00:34:20,727 --> 00:34:22,462 So the glaciers were moving, 640 00:34:22,562 --> 00:34:24,597 and these have unique sounds. 641 00:34:24,698 --> 00:34:27,467 It was loud, and it wasn't terribly long, 642 00:34:27,567 --> 00:34:29,736 and it wasn't rhythmic. 643 00:34:29,836 --> 00:34:32,172 The noise created by the friction between 644 00:34:32,272 --> 00:34:34,708 the enormous slabs of ice is identical 645 00:34:34,808 --> 00:34:38,078 to the one first picked up by Fox and his team at NOAA. 646 00:34:41,047 --> 00:34:43,483 It had a similar signature, similar frequency, 647 00:34:43,583 --> 00:34:45,819 and similar volume to what they had heard 648 00:34:45,919 --> 00:34:48,788 in the '90s, so this actually was a sound 649 00:34:48,888 --> 00:34:50,790 made by ice breaking apart 650 00:34:50,890 --> 00:34:53,360 and not by an underwater sea creature. 651 00:34:56,129 --> 00:34:59,032 Scientists believe that glacial cavving 652 00:34:59,132 --> 00:35:01,801 is the most likely source of the Bloop. 653 00:35:01,901 --> 00:35:04,738 Still, many continue to wonder what unknown, 654 00:35:04,838 --> 00:35:07,607 magnificent creatures lurk in the deep. 655 00:35:07,707 --> 00:35:10,110 There's so much left to explore, 656 00:35:10,210 --> 00:35:13,313 and we don't really know what else we're gonna find. 657 00:35:16,850 --> 00:35:20,120 Today, this hydrophone, used to detect underwater sounds, 658 00:35:20,220 --> 00:35:22,989 is on display at the New Bedford Whaling Museum 659 00:35:23,089 --> 00:35:24,758 in Massachusetts. 660 00:35:24,858 --> 00:35:26,893 It recalls the maritime mystery 661 00:35:26,993 --> 00:35:29,329 and the Bloop heard round the world. 662 00:35:32,899 --> 00:35:35,969 An 85 pound sturgeon from the Gulf of Mexico... 663 00:35:36,069 --> 00:35:39,172 A massive devil ray with a 4 foot wing span. 664 00:35:39,272 --> 00:35:42,075 and an alligator gar, 665
