WEBVTT - From the Vault: The Great Wave

0:00:05.720 --> 0:00:07.840
<v Speaker 1>Hey, Welcome to Stuff to Blow your Mind. My name

0:00:07.880 --> 0:00:11.120
<v Speaker 1>is Robert Lamb and I'm Joe McCormick, and it's Saturday.

0:00:11.200 --> 0:00:13.680
<v Speaker 1>Time to dive into the vault. This time we're doing

0:00:13.720 --> 0:00:17.840
<v Speaker 1>an episode that originally aired on May nineteen. This one

0:00:17.920 --> 0:00:21.360
<v Speaker 1>was called The Great Wave. It was about giant waves,

0:00:21.520 --> 0:00:24.880
<v Speaker 1>rogue waves. I remember this episode being very interesting, especially

0:00:25.560 --> 0:00:28.520
<v Speaker 1>because in preparing for it, it was when I, uh,

0:00:28.840 --> 0:00:33.280
<v Speaker 1>I learned about the the incredible survival by sea voyage

0:00:33.320 --> 0:00:37.680
<v Speaker 1>of was it the Shackleton Expedition? Yes, I believe so. Yeah.

0:00:37.720 --> 0:00:41.320
<v Speaker 1>So this one, this one is filled with aquatic peril

0:00:41.760 --> 0:00:43.879
<v Speaker 1>and uh and I seem to recall there's a fair

0:00:43.920 --> 0:00:49.040
<v Speaker 1>amount of sort of looking at at historical accounts and

0:00:49.040 --> 0:00:51.360
<v Speaker 1>people weighing in on exactly what kind of wave we

0:00:51.360 --> 0:00:57.240
<v Speaker 1>were talking about. Here, Welcome to Stuff to Blow your Mind.

0:00:57.280 --> 0:01:06.319
<v Speaker 1>A production of I Heart Radios has to work. Hey, you,

0:01:06.360 --> 0:01:08.240
<v Speaker 1>Welcome to Stuff to Blow your Mind. My name is

0:01:08.319 --> 0:01:10.520
<v Speaker 1>Robert Lamb and I'm Joe McCormick, and I'm want to

0:01:10.600 --> 0:01:12.880
<v Speaker 1>kick off this episode by talking about a piece of art.

0:01:13.520 --> 0:01:15.760
<v Speaker 1>And it's a piece of art that I imagine a

0:01:15.760 --> 0:01:18.120
<v Speaker 1>lot of you have seen and if you haven't seen it.

0:01:18.160 --> 0:01:20.520
<v Speaker 1>You can, and you're not driving a vehicle or anything

0:01:20.600 --> 0:01:22.319
<v Speaker 1>right now, you can easily look it up and you

0:01:22.319 --> 0:01:25.800
<v Speaker 1>can certainly find it for the landing page for this episode.

0:01:25.800 --> 0:01:28.399
<v Speaker 1>It's stuff to Blow your Mind dot com. It is

0:01:28.760 --> 0:01:31.440
<v Speaker 1>a Japanese print. It is a title the Great Wave

0:01:31.880 --> 0:01:36.319
<v Speaker 1>off Kanagawa, and it's a nineteenth century Edo period would

0:01:36.360 --> 0:01:41.679
<v Speaker 1>block print by Katsushika Hokusai, and it depicts a great

0:01:41.840 --> 0:01:47.080
<v Speaker 1>wave endangering ships off the coast of Kanagawa. And it

0:01:47.160 --> 0:01:50.120
<v Speaker 1>was once thought to depict a tsunami, but now most

0:01:50.840 --> 0:01:55.400
<v Speaker 1>commentators think that it actually depicts a rogue wave. UM. Now,

0:01:55.480 --> 0:01:58.600
<v Speaker 1>the the artist here, he explored this subject matter many

0:01:58.680 --> 0:02:01.320
<v Speaker 1>times in his career, so if you look at other

0:02:01.320 --> 0:02:04.040
<v Speaker 1>images he created, there are plenty of other waves, but

0:02:04.120 --> 0:02:07.120
<v Speaker 1>this particular print is considered the peak the culmination of

0:02:07.200 --> 0:02:10.240
<v Speaker 1>sixty years in the arts. UM And since it's a

0:02:10.280 --> 0:02:12.800
<v Speaker 1>woodblock print and not a painting, you can actually find

0:02:12.800 --> 0:02:16.240
<v Speaker 1>it in numerous museums around the world, thus increasing the

0:02:16.240 --> 0:02:19.000
<v Speaker 1>odds that you have seen this image, if not online

0:02:19.000 --> 0:02:22.160
<v Speaker 1>and perhaps in purpose in person. But I think one

0:02:22.200 --> 0:02:25.080
<v Speaker 1>of the great things about it is that it captures

0:02:25.560 --> 0:02:29.200
<v Speaker 1>a sense of the majesty of a great wave. The

0:02:29.280 --> 0:02:31.880
<v Speaker 1>idea that it's it's there's like a topography of the

0:02:31.919 --> 0:02:36.280
<v Speaker 1>ocean visible, the ocean surface visible in this picture. That

0:02:36.280 --> 0:02:39.840
<v Speaker 1>that reminds us that a wave can be a mountain. Well, yeah,

0:02:39.880 --> 0:02:42.560
<v Speaker 1>and the wave in the in the woodblock even what

0:02:42.600 --> 0:02:44.440
<v Speaker 1>do you call it a print or a painting when

0:02:44.520 --> 0:02:48.040
<v Speaker 1>it's the painting whatever it is on this image, Uh,

0:02:48.320 --> 0:02:51.600
<v Speaker 1>the wave resembles the mountain in the background, and the

0:02:51.760 --> 0:02:54.600
<v Speaker 1>mountain and the backgrounds has sort of a blue gray,

0:02:55.240 --> 0:02:57.720
<v Speaker 1>uh slope, and then the white peak of course covered

0:02:57.760 --> 0:02:59.920
<v Speaker 1>in snow. The waves are much like that with these

0:03:00.080 --> 0:03:02.800
<v Speaker 1>uh the white surging foam at the top. But in

0:03:02.880 --> 0:03:06.800
<v Speaker 1>the painting, the foam as these like hooks that almost

0:03:06.840 --> 0:03:09.920
<v Speaker 1>looked like eagles talents reaching out of the top of

0:03:09.960 --> 0:03:12.760
<v Speaker 1>this wall of water. And there's there's a way that

0:03:13.040 --> 0:03:15.360
<v Speaker 1>I at least often look to this painting without even

0:03:15.400 --> 0:03:18.560
<v Speaker 1>realizing they were supposed to be boats represented at the bottom. Yeah,

0:03:18.600 --> 0:03:20.840
<v Speaker 1>it's kind of easy to miss the boats. They're they're

0:03:21.440 --> 0:03:24.120
<v Speaker 1>swallowed up by what's going on all around. It's a

0:03:24.120 --> 0:03:27.000
<v Speaker 1>beautiful piece of art. And I don't know why, but

0:03:27.080 --> 0:03:29.560
<v Speaker 1>I've always when I've looked at it before thought of

0:03:29.560 --> 0:03:33.040
<v Speaker 1>it as somehow calming or like a picture of sort

0:03:33.040 --> 0:03:36.520
<v Speaker 1>of like serene nature, which is hilarious because it's depicting

0:03:36.520 --> 0:03:39.960
<v Speaker 1>a scene of utter chaos and destruction and terror, right,

0:03:40.000 --> 0:03:42.640
<v Speaker 1>I mean it's spoken like a true landsman, right when

0:03:42.680 --> 0:03:45.480
<v Speaker 1>clearly like this is a product of of an island

0:03:45.520 --> 0:03:49.160
<v Speaker 1>culture that it was very you know, very aware of

0:03:49.200 --> 0:03:53.000
<v Speaker 1>the dangers posed by the by the ocean. And uh yeah,

0:03:53.280 --> 0:03:56.200
<v Speaker 1>because I probably am in the same same boat. Uh No.

0:03:56.320 --> 0:03:58.680
<v Speaker 1>Pun intended with you is that when I've seen the

0:03:58.680 --> 0:04:01.160
<v Speaker 1>image in the past, it was just I was like, ah, yeah,

0:04:01.400 --> 0:04:06.080
<v Speaker 1>serene nature. But no, this is a cresting mountain of

0:04:06.360 --> 0:04:11.440
<v Speaker 1>oceanic destruction, or at least potential destruction in terms of

0:04:11.680 --> 0:04:16.080
<v Speaker 1>human activities on or near the ocean the mountain that flows.

0:04:16.120 --> 0:04:19.000
<v Speaker 1>So speaking of the dangers of the ocean, I mean,

0:04:19.520 --> 0:04:21.479
<v Speaker 1>there are many of them, and we know what many

0:04:21.520 --> 0:04:25.440
<v Speaker 1>of them are. But we often discuss ancient beastiaries and

0:04:25.640 --> 0:04:28.640
<v Speaker 1>records of monsters and strange creatures from the ancient world,

0:04:28.720 --> 0:04:31.279
<v Speaker 1>and of course some of the best ones, even through

0:04:31.320 --> 0:04:34.440
<v Speaker 1>like the medieval period, are of sea monsters. So you've

0:04:34.440 --> 0:04:37.520
<v Speaker 1>got these stories about lizards that kill with the gaze

0:04:37.600 --> 0:04:41.360
<v Speaker 1>or giant sea monsters that suck entire ships into their mouths,

0:04:41.400 --> 0:04:43.600
<v Speaker 1>And they can be funny to read about now, especially

0:04:43.600 --> 0:04:46.440
<v Speaker 1>with the certainty that ancient writers had when they talked

0:04:46.480 --> 0:04:49.400
<v Speaker 1>about these subjects. But one point I've made before and

0:04:49.440 --> 0:04:51.359
<v Speaker 1>that I want to echo again is I think it

0:04:51.520 --> 0:04:55.960
<v Speaker 1>was not at all stupid or irrational for ancient people's

0:04:56.040 --> 0:04:58.240
<v Speaker 1>to believe in sea monsters. I think it was a

0:04:58.360 --> 0:05:01.359
<v Speaker 1>perfectly reasonable and rap channel thing for them to assume.

0:05:01.640 --> 0:05:03.760
<v Speaker 1>And there are a few reasons for this. We've touched

0:05:03.760 --> 0:05:05.640
<v Speaker 1>on some of them on the show before. Number one,

0:05:05.680 --> 0:05:08.159
<v Speaker 1>there actually are sea monsters in a way. We just

0:05:08.240 --> 0:05:10.640
<v Speaker 1>call them by different names now, like you know the

0:05:10.680 --> 0:05:14.160
<v Speaker 1>sperm whale, blue whale, giant squid, the sunfish, the lion's

0:05:14.240 --> 0:05:19.080
<v Speaker 1>main jellyfish. These are all giant, magnificent, all inspiring creatures.

0:05:19.240 --> 0:05:21.919
<v Speaker 1>But what's changed is that we've fit them into a

0:05:21.960 --> 0:05:25.279
<v Speaker 1>standard evolutionary taxonomy. We think of them as animals that

0:05:25.400 --> 0:05:28.680
<v Speaker 1>have common origins with the other animals. But when ancient

0:05:28.720 --> 0:05:31.880
<v Speaker 1>sailors told stories of these giant beasts out in the ocean, meany,

0:05:31.920 --> 0:05:34.880
<v Speaker 1>we're probably telling the truth to the best of their ability.

0:05:35.000 --> 0:05:38.480
<v Speaker 1>They saw something huge and strange and terrifying, and they're

0:05:38.480 --> 0:05:41.520
<v Speaker 1>trying to remember and describe what it was. And then

0:05:41.520 --> 0:05:43.200
<v Speaker 1>on top of that, you're dealing with it with just

0:05:43.279 --> 0:05:47.520
<v Speaker 1>a culture and a legacy um of of danger upon

0:05:48.000 --> 0:05:50.520
<v Speaker 1>the sea and beneath the sea. Yes, so there were

0:05:50.560 --> 0:05:53.480
<v Speaker 1>those two things come together. I mean, here there'll be monsters,

0:05:53.600 --> 0:05:57.320
<v Speaker 1>right exactly. And because the sea, you know, a life

0:05:57.360 --> 0:05:59.800
<v Speaker 1>at sea has long I think, been associated with the

0:06:00.040 --> 0:06:03.400
<v Speaker 1>kind of with a kind of daring and bravado. Right.

0:06:04.160 --> 0:06:06.479
<v Speaker 1>But also I think there's another reason it was sort

0:06:06.520 --> 0:06:09.680
<v Speaker 1>of rational to believe in giant krakens that could pull

0:06:09.760 --> 0:06:13.000
<v Speaker 1>ships down to their doom. And it's that Poseidon is

0:06:13.040 --> 0:06:15.400
<v Speaker 1>one of the cruelest and most fickle of the gods.

0:06:15.440 --> 0:06:18.040
<v Speaker 1>That that's not an accident that the Greek myths are

0:06:18.080 --> 0:06:20.880
<v Speaker 1>like that it is not at all uncommon for ships

0:06:20.920 --> 0:06:24.040
<v Speaker 1>to set sail on the high seas and then just vanish,

0:06:24.279 --> 0:06:27.640
<v Speaker 1>leaving behind no trace. At all. Other times you might

0:06:27.720 --> 0:06:31.120
<v Speaker 1>find a giant, sturdy ship wrecked with no apparent cause,

0:06:31.480 --> 0:06:35.080
<v Speaker 1>like it's masked and rigging, smashed bits, with giant holes

0:06:35.080 --> 0:06:37.920
<v Speaker 1>blown in its solid hull. And when when you see

0:06:38.040 --> 0:06:40.360
<v Speaker 1>rex like this, uh, In fact, some of the Rex

0:06:40.400 --> 0:06:43.320
<v Speaker 1>I was looking at in preparation for this episode. It

0:06:43.400 --> 0:06:45.680
<v Speaker 1>calls to mind, uh, I was thinking about that poem

0:06:45.680 --> 0:06:48.120
<v Speaker 1>we've talked about on the show before, Alfred Lord Tennyson's

0:06:48.320 --> 0:06:51.400
<v Speaker 1>The Kraken, where you know, there's this beast battening upon

0:06:51.560 --> 0:06:54.440
<v Speaker 1>huge sea worms in his sleep until the latter fire

0:06:54.480 --> 0:06:57.000
<v Speaker 1>shall heat the deep and he comes up to the surface.

0:06:57.040 --> 0:06:59.280
<v Speaker 1>And of course in the poem he dies. But what's

0:06:59.320 --> 0:07:01.560
<v Speaker 1>more likely, say, he's actually gonna like punch a hole

0:07:01.640 --> 0:07:04.360
<v Speaker 1>right in the middle of your ship. Now, obviously there

0:07:04.400 --> 0:07:07.440
<v Speaker 1>are many ways for ships to wreck and sync causing

0:07:07.440 --> 0:07:10.040
<v Speaker 1>them to vanish without a trace. They can hit rocks,

0:07:10.120 --> 0:07:13.360
<v Speaker 1>they can hit hidden reefs, they can capsize and take

0:07:13.360 --> 0:07:16.720
<v Speaker 1>on water. But there is one particular phenomenon that sailors

0:07:16.720 --> 0:07:21.800
<v Speaker 1>have long been telling these dark, majestically terrifying stories about,

0:07:22.280 --> 0:07:26.080
<v Speaker 1>and it's something that could explain many sudden disappearances of

0:07:26.120 --> 0:07:29.520
<v Speaker 1>seagoing vessels if it was anything more than a fantasy.

0:07:29.720 --> 0:07:32.840
<v Speaker 1>And it's what you mentioned about the woodblock painting earlier.

0:07:32.920 --> 0:07:36.560
<v Speaker 1>The monster wave, the rogue wave also known as a

0:07:36.680 --> 0:07:39.560
<v Speaker 1>freak wave, which I like because it sounds like either

0:07:39.600 --> 0:07:43.040
<v Speaker 1>a musical subgenre or some sort of like misfit style

0:07:43.120 --> 0:07:46.520
<v Speaker 1>punk band, you know, freak wave. It's a genre that

0:07:46.560 --> 0:07:49.680
<v Speaker 1>mixes punk music with carnival music and circus music. No,

0:07:49.880 --> 0:07:52.040
<v Speaker 1>I you know, I say that, but I bet that's

0:07:52.080 --> 0:07:55.640
<v Speaker 1>actually a genre somewhere. Probably at this point all sub

0:07:55.680 --> 0:07:59.080
<v Speaker 1>genres exist. But so, yeah, the the idea of a

0:07:59.160 --> 0:08:01.160
<v Speaker 1>rogue wave or a monster waves, so we're not just

0:08:01.240 --> 0:08:06.040
<v Speaker 1>talking about rough seas in general, but a single gigantic wave,

0:08:06.440 --> 0:08:10.080
<v Speaker 1>an unbelievably high a wall of water that appears as

0:08:10.120 --> 0:08:13.080
<v Speaker 1>if out of nowhere and crashes over your ship like

0:08:13.120 --> 0:08:16.120
<v Speaker 1>a hammer of the sea gods, and so sailors have

0:08:16.240 --> 0:08:18.720
<v Speaker 1>talked about this, and we want to ask today, could

0:08:18.800 --> 0:08:21.520
<v Speaker 1>these tales be true? Do we now know whether they're true?

0:08:21.560 --> 0:08:24.760
<v Speaker 1>And could they explain many of histories vanished ships and

0:08:25.200 --> 0:08:28.400
<v Speaker 1>hulls broken like toys. Now at this point, I do

0:08:28.440 --> 0:08:31.760
<v Speaker 1>want to mention that in our research, I think we'd

0:08:31.760 --> 0:08:35.400
<v Speaker 1>hope to maybe throw in more like a giant wave myths,

0:08:35.880 --> 0:08:39.680
<v Speaker 1>more accounts from say, ancient histories of of giant waves

0:08:39.679 --> 0:08:43.720
<v Speaker 1>as opposed to organic sea monsters. And I'm not saying

0:08:43.760 --> 0:08:46.120
<v Speaker 1>they don't exist. They may very well exist. But I

0:08:46.200 --> 0:08:49.280
<v Speaker 1>had trouble finding them, and we're discussing why that might be.

0:08:49.520 --> 0:08:51.959
<v Speaker 1>I mean, we could go back to what you said earlier,

0:08:52.000 --> 0:08:54.920
<v Speaker 1>how a ship disappears at sea, perhaps caused by a

0:08:54.920 --> 0:08:57.679
<v Speaker 1>giant wave, and the story is about a sea monster,

0:08:57.800 --> 0:09:00.719
<v Speaker 1>or it becomes about an organic sea monster. Yes. Uh.

0:09:00.760 --> 0:09:03.920
<v Speaker 1>And one point of parallel here is that obviously even

0:09:03.920 --> 0:09:06.880
<v Speaker 1>the ancient people's knew about the idea that the ship

0:09:06.920 --> 0:09:09.600
<v Speaker 1>could encounter, say, bad weather while I was out at sea,

0:09:09.640 --> 0:09:11.920
<v Speaker 1>and be wrecked and and all that. So it's not

0:09:11.960 --> 0:09:14.199
<v Speaker 1>like there was no other way for ships to sink.

0:09:14.400 --> 0:09:16.520
<v Speaker 1>But the way in which a rogue wave as a

0:09:16.600 --> 0:09:19.920
<v Speaker 1>concept resembles a sea monster is is that it's unexpected,

0:09:20.040 --> 0:09:22.000
<v Speaker 1>you know that, that it reaches up out of the deep,

0:09:22.040 --> 0:09:24.360
<v Speaker 1>that it's much higher than all the other waves in

0:09:24.400 --> 0:09:26.600
<v Speaker 1>the in the ocean, and it just takes you completely

0:09:26.600 --> 0:09:29.160
<v Speaker 1>by surprise. And that's key here. It's not a situation

0:09:29.160 --> 0:09:31.160
<v Speaker 1>of like, oh, suddenly all the waves were enormous. No,

0:09:31.360 --> 0:09:35.760
<v Speaker 1>suddenly one wave stands vastly um above all the others,

0:09:35.840 --> 0:09:39.199
<v Speaker 1>much like the mountain of a wave in the print

0:09:39.280 --> 0:09:41.160
<v Speaker 1>we were discussing at the top of the episode. Now,

0:09:41.200 --> 0:09:44.400
<v Speaker 1>obviously lots of ships in history of encountered rough seas,

0:09:44.440 --> 0:09:47.839
<v Speaker 1>like certain regions of the ocean and certain weather patterns

0:09:47.880 --> 0:09:51.200
<v Speaker 1>can generate lots of chop and high waves. But ships

0:09:51.200 --> 0:09:54.280
<v Speaker 1>are usually made to withstand bad weather. That's part of

0:09:54.320 --> 0:09:56.520
<v Speaker 1>what ship design is for. You know, you say, okay,

0:09:56.640 --> 0:09:58.800
<v Speaker 1>might encounter this kind of weather, so we need to

0:09:58.840 --> 0:10:01.920
<v Speaker 1>make it this amounts strong to withstand it. Right, Like,

0:10:01.960 --> 0:10:04.480
<v Speaker 1>if you know you're going around the cape, you're gonna

0:10:04.559 --> 0:10:09.240
<v Speaker 1>you're gonna build and sail vessels designed for for rough seas. Yeah,

0:10:09.280 --> 0:10:11.720
<v Speaker 1>and these wave patterns have long been understood to be

0:10:11.760 --> 0:10:15.160
<v Speaker 1>predictable within certain parameters. You make a ship strong and

0:10:15.200 --> 0:10:18.280
<v Speaker 1>she'll hold. But what we're talking about with these monster

0:10:18.320 --> 0:10:21.240
<v Speaker 1>waves stories is a wave that suddenly appears without warning

0:10:21.440 --> 0:10:24.280
<v Speaker 1>and is at least twice as high as all the

0:10:24.320 --> 0:10:27.040
<v Speaker 1>other waves in the sea. And of course, when you're

0:10:27.040 --> 0:10:29.439
<v Speaker 1>talking about a wave of water that's twice as high

0:10:29.480 --> 0:10:31.960
<v Speaker 1>as the other waves around it, uh, it's something where

0:10:32.040 --> 0:10:34.360
<v Speaker 1>you know, the power and destructiveness of it doesn't just

0:10:34.440 --> 0:10:37.920
<v Speaker 1>scale linearly. You know, it becomes a new kind of

0:10:37.960 --> 0:10:40.680
<v Speaker 1>phenomenon you're dealing with. Now, I want to be I

0:10:40.679 --> 0:10:44.000
<v Speaker 1>want to be clear here that we're talking about true

0:10:44.120 --> 0:10:47.920
<v Speaker 1>rogue waves or monster waves, freak waves, etcetera. Here, Uh,

0:10:47.960 --> 0:10:50.920
<v Speaker 1>that do seem to come out of nowhere. And they're

0:10:50.960 --> 0:10:54.599
<v Speaker 1>not to be confused with giant waves generated by seismic activity,

0:10:54.800 --> 0:10:59.600
<v Speaker 1>right like underwater volcanic eruptions, earthquakes, or cascades like riding,

0:11:00.000 --> 0:11:01.720
<v Speaker 1>though those can be incredible and I mean, just for

0:11:01.760 --> 0:11:05.240
<v Speaker 1>an example, um, I was reading about the earthquake generated

0:11:05.280 --> 0:11:10.360
<v Speaker 1>tsunami in Alaska's LaToya Bay, which, according to Discover magazine,

0:11:10.840 --> 0:11:14.400
<v Speaker 1>was a four hundred feet taller than the Empire State Building. Yeah,

0:11:14.440 --> 0:11:17.240
<v Speaker 1>they're they're people have done like illustrations of this online.

0:11:17.320 --> 0:11:20.520
<v Speaker 1>You can find where it's It's just staggering like it

0:11:20.520 --> 0:11:22.600
<v Speaker 1>it created this. I think it was supposed to be

0:11:22.600 --> 0:11:26.120
<v Speaker 1>like seventeen hundred feet roughly. Yeah. According to the University

0:11:26.120 --> 0:11:30.680
<v Speaker 1>of Alaska Fairbanks quote, the earthquake shook loose millions of

0:11:30.720 --> 0:11:33.319
<v Speaker 1>cubic yards of dirt and rocks from a forty degree

0:11:33.400 --> 0:11:36.280
<v Speaker 1>slope in the northeast corner of the bay. The rock

0:11:36.400 --> 0:11:39.240
<v Speaker 1>mass displaced a large body of water, causing both of

0:11:39.280 --> 0:11:43.000
<v Speaker 1>the splash wave that rose to one thousand, seven hundred

0:11:43.080 --> 0:11:46.040
<v Speaker 1>forty feet and a gravity wave that was one fifty

0:11:46.040 --> 0:11:48.319
<v Speaker 1>feet high. At the head of the bay. The waves

0:11:48.320 --> 0:11:51.320
<v Speaker 1>sheared and stripped the bark from thousands of trees, some

0:11:51.440 --> 0:11:54.280
<v Speaker 1>of them four ft in diameter, just clear cut the

0:11:54.400 --> 0:11:56.880
<v Speaker 1>land next to the bay. Yeah, and this occurred in

0:11:57.120 --> 0:12:01.200
<v Speaker 1>night again, but they seem seemingly something like it occurred

0:12:01.280 --> 0:12:04.680
<v Speaker 1>at the same area in thirty six and also in

0:12:04.840 --> 0:12:07.440
<v Speaker 1>the eighteen fifties and eighteen seventy four as well. So

0:12:07.480 --> 0:12:10.800
<v Speaker 1>that's just a taste of the destructive possibilities of seismically

0:12:10.840 --> 0:12:14.360
<v Speaker 1>generated waves in shallow coastal areas. Yeah, and of course

0:12:14.720 --> 0:12:17.760
<v Speaker 1>so we've got tsunamis as well. Tsunamis happen when something

0:12:17.840 --> 0:12:20.600
<v Speaker 1>happens out in the ocean. Uh, there's like an earthquake,

0:12:20.840 --> 0:12:23.360
<v Speaker 1>you know, shift in the sea floor and eruptions something

0:12:23.400 --> 0:12:25.560
<v Speaker 1>like that, and then there's a pressure wave that goes

0:12:25.640 --> 0:12:28.960
<v Speaker 1>throughout the water column towards the shore. As it nears

0:12:28.960 --> 0:12:31.319
<v Speaker 1>the shore. Of course, as it enters the shallow waters,

0:12:31.360 --> 0:12:33.839
<v Speaker 1>that's when it becomes really destructive because that mass of

0:12:33.920 --> 0:12:36.559
<v Speaker 1>pressure it rises up out of the water and it

0:12:36.640 --> 0:12:39.360
<v Speaker 1>you know, keeps coming and flooding against the shore, taking

0:12:39.520 --> 0:12:42.480
<v Speaker 1>whatever is on the shore along with it. Yeah. No, No, obviously,

0:12:42.600 --> 0:12:46.120
<v Speaker 1>atmospheric conditions are complicated, as we've discussed on the show before,

0:12:46.120 --> 0:12:51.520
<v Speaker 1>the complex systems, a lot of forces conversion together, it

0:12:51.520 --> 0:12:55.360
<v Speaker 1>becomes very difficult to predict atmospheric conditions and weather conditions

0:12:55.840 --> 0:12:58.320
<v Speaker 1>increasingly far in the future. And of course we have

0:12:58.360 --> 0:13:02.240
<v Speaker 1>a very similar situation with the movement of the fluids

0:13:02.240 --> 0:13:06.240
<v Speaker 1>in the ocean. But uh, but but with these cases,

0:13:06.240 --> 0:13:08.080
<v Speaker 1>they make a lot more sense to us, right, the tsunami,

0:13:08.080 --> 0:13:12.240
<v Speaker 1>the earthquake generated tsunami, because we can we can easily say, well,

0:13:12.280 --> 0:13:14.120
<v Speaker 1>this is the thing, this is the great event that

0:13:14.200 --> 0:13:18.000
<v Speaker 1>caused the great wave. And the idea of a wave

0:13:18.160 --> 0:13:22.720
<v Speaker 1>just coming out seemingly out of nowhere the sources as

0:13:23.040 --> 0:13:25.439
<v Speaker 1>is seeming a little more elusive, like it seems to

0:13:25.480 --> 0:13:30.280
<v Speaker 1>be emerging from the complex interplay of different storm patterns

0:13:30.320 --> 0:13:32.640
<v Speaker 1>and occurrents. Yeah, you might be just out in a

0:13:32.720 --> 0:13:35.920
<v Speaker 1>storm with waves that are pretty regular, certain height, coming

0:13:35.920 --> 0:13:37.959
<v Speaker 1>and going and going and going and going, and then

0:13:38.040 --> 0:13:42.319
<v Speaker 1>there's one suddenly the mountain arrives, or so the stories

0:13:42.360 --> 0:13:44.920
<v Speaker 1>tell us. Right, So the question is wind sailors tell

0:13:44.960 --> 0:13:47.640
<v Speaker 1>these stories? Are they true? And so I thought maybe

0:13:47.679 --> 0:13:50.040
<v Speaker 1>we should look at a couple of first hand accounts.

0:13:50.320 --> 0:13:53.199
<v Speaker 1>You ready, Robert, let's do it. Who's our first adventure? Well,

0:13:53.200 --> 0:13:56.120
<v Speaker 1>I thought we should turn to one first hand account

0:13:56.160 --> 0:14:00.240
<v Speaker 1>from the Antarctic explorer Ernest Shackleton, which came for the

0:14:00.280 --> 0:14:03.800
<v Speaker 1>famous voyage of the James Cared. Now, this voyage was

0:14:03.960 --> 0:14:08.360
<v Speaker 1>one part of the overall survival journey after the failure

0:14:08.520 --> 0:14:12.160
<v Speaker 1>of Shackleton's Antarctic expedition in a ship called the Endurance

0:14:12.240 --> 0:14:15.840
<v Speaker 1>that started in nineteen fourteen. And this is an absolutely

0:14:15.880 --> 0:14:19.120
<v Speaker 1>astounding survival story that is worth looking up if you've

0:14:19.120 --> 0:14:20.880
<v Speaker 1>never read it. And this is this is only one

0:14:20.960 --> 0:14:23.840
<v Speaker 1>part of the story, um, but the short version of

0:14:23.840 --> 0:14:27.200
<v Speaker 1>the context here was a nineteen fourteen Shackleton and crew

0:14:27.240 --> 0:14:30.200
<v Speaker 1>set out for Antarctica in this ship, the Endurance. But

0:14:30.280 --> 0:14:33.240
<v Speaker 1>the ship became trapped in ice in the wet El Sea,

0:14:33.480 --> 0:14:36.160
<v Speaker 1>and the ship eventually sank. And of course this was

0:14:36.320 --> 0:14:40.040
<v Speaker 1>nineteen fourteen or fifteen. You're in Antarctica that you know,

0:14:40.240 --> 0:14:42.960
<v Speaker 1>your ship sinking is sort of a death sentence. Yeah,

0:14:43.000 --> 0:14:46.560
<v Speaker 1>I mean even today, it's very bad news. So the

0:14:46.640 --> 0:14:49.280
<v Speaker 1>crew made their way, you know, they're out there stranded,

0:14:49.440 --> 0:14:52.040
<v Speaker 1>and the crew made their way to an uninhabited island

0:14:52.120 --> 0:14:55.200
<v Speaker 1>known as Elephant Island. From after where the ship sank,

0:14:55.520 --> 0:14:58.920
<v Speaker 1>and Shackleton reasoned that their only hope of survival was

0:14:58.960 --> 0:15:02.520
<v Speaker 1>seeking help and enforcement from the island of South Georgia,

0:15:02.600 --> 0:15:04.840
<v Speaker 1>where he knew that there was a whaling station. So

0:15:04.880 --> 0:15:06.320
<v Speaker 1>if they got to where the people were at the

0:15:06.320 --> 0:15:09.080
<v Speaker 1>whaling station there, they could, you know, come back for

0:15:09.160 --> 0:15:12.400
<v Speaker 1>rescue with the bigger ship. But South Georgia was about

0:15:12.480 --> 0:15:17.440
<v Speaker 1>eight hundred miles or hundred kilometers away over terrible seas.

0:15:17.480 --> 0:15:19.840
<v Speaker 1>You know the seas around Antarctica are you know, there's

0:15:19.880 --> 0:15:23.200
<v Speaker 1>they're icy, there's rough, bad weather. It's not a place

0:15:23.240 --> 0:15:26.360
<v Speaker 1>to be sailing in an unreinforced vessel. And the only

0:15:26.440 --> 0:15:29.240
<v Speaker 1>viable vessel they had for making the voyage because remember

0:15:29.240 --> 0:15:31.680
<v Speaker 1>their ships, saying that the best thing they had to

0:15:31.760 --> 0:15:34.200
<v Speaker 1>use was a twenty two foot or about six and

0:15:34.200 --> 0:15:38.320
<v Speaker 1>a half meter lifeboat called the James Care. So Shackleton

0:15:38.480 --> 0:15:40.440
<v Speaker 1>and a few others that they left the rest of

0:15:40.440 --> 0:15:43.840
<v Speaker 1>the crew sheltered at Elephant Island, and they set out

0:15:43.840 --> 0:15:47.040
<v Speaker 1>on this brutal journey to get a rescue party, during

0:15:47.080 --> 0:15:50.080
<v Speaker 1>which they encountered ice and bad weather. The story is

0:15:50.160 --> 0:15:53.720
<v Speaker 1>harrowing and amazing. They talked about how you know ice

0:15:53.720 --> 0:15:56.040
<v Speaker 1>would keep building up on the boat because it's freezing,

0:15:56.320 --> 0:15:59.240
<v Speaker 1>and they'd be soaked by all these horrible waves that

0:15:59.280 --> 0:16:01.840
<v Speaker 1>are pounding on Them's freezing weather, and they'd have to

0:16:01.920 --> 0:16:04.840
<v Speaker 1>keep constantly chipping the ice off of the boat because

0:16:04.840 --> 0:16:06.880
<v Speaker 1>the ice would weigh the boat down and start to

0:16:06.920 --> 0:16:09.560
<v Speaker 1>make it sink um. And you know, this is a

0:16:09.680 --> 0:16:13.000
<v Speaker 1>this is like a multi week journey. And at one point,

0:16:13.080 --> 0:16:16.480
<v Speaker 1>while Shackleton was at the tiller of the boat, uh so,

0:16:16.520 --> 0:16:18.400
<v Speaker 1>there had been very bad weather, of course, and then

0:16:18.440 --> 0:16:21.120
<v Speaker 1>he's at the tiller one time and he thinks he

0:16:21.240 --> 0:16:24.760
<v Speaker 1>sees the clouds breaking and a clear sky up ahead.

0:16:24.880 --> 0:16:27.920
<v Speaker 1>And then I want to quote from Shackleton's own account, quote,

0:16:28.320 --> 0:16:30.880
<v Speaker 1>I called to the other men that the sky was clearing.

0:16:31.200 --> 0:16:33.720
<v Speaker 1>And then a moment later I realized that what I

0:16:33.760 --> 0:16:36.440
<v Speaker 1>had seen was not a rift in the clouds, but

0:16:36.520 --> 0:16:40.560
<v Speaker 1>the white crest of an enormous wave. During twenty six

0:16:40.640 --> 0:16:43.600
<v Speaker 1>years experience of the ocean, in all its moods, I

0:16:43.640 --> 0:16:46.680
<v Speaker 1>had not encountered a wave of so gigantic. It was

0:16:46.720 --> 0:16:49.920
<v Speaker 1>a mighty upheaval of the ocean, a thing quite apart

0:16:50.000 --> 0:16:52.240
<v Speaker 1>from the big, white capped seas that had been our

0:16:52.320 --> 0:16:55.800
<v Speaker 1>tireless enemies. For many days, I shouted, for God's sake,

0:16:55.840 --> 0:16:58.920
<v Speaker 1>hold on, it's got us. Then came a moment of

0:16:58.920 --> 0:17:02.960
<v Speaker 1>suspense that seemed drawn out into hours. White surge the

0:17:03.040 --> 0:17:05.959
<v Speaker 1>foam of the breaking sea around us. We felt our

0:17:06.000 --> 0:17:09.600
<v Speaker 1>boat lifted and flung forward like a cork and breaking surf.

0:17:09.960 --> 0:17:12.919
<v Speaker 1>We were in a seething chaos of tortured water, but

0:17:13.080 --> 0:17:16.200
<v Speaker 1>somehow the boat lived through it, half full of water,

0:17:16.520 --> 0:17:19.439
<v Speaker 1>sagging to the dead weight and shuddering under the blow.

0:17:19.960 --> 0:17:22.720
<v Speaker 1>We bailed with the energy of men fighting for life,

0:17:22.960 --> 0:17:25.960
<v Speaker 1>flinging the water over the sides, with every receptacle that

0:17:26.040 --> 0:17:29.080
<v Speaker 1>came to our hands, and after ten minutes of uncertainty,

0:17:29.320 --> 0:17:32.639
<v Speaker 1>we felt the boat renew her life beneath us. So

0:17:32.720 --> 0:17:35.840
<v Speaker 1>the fact that this giant wave did not sink or

0:17:35.880 --> 0:17:39.240
<v Speaker 1>just completely smash their tiny boat to pieces is one

0:17:39.280 --> 0:17:43.080
<v Speaker 1>of the many bizarre miracles of this unbelievable journey. Uh.

0:17:43.160 --> 0:17:45.359
<v Speaker 1>You know, you always have to wonder, like how things

0:17:45.400 --> 0:17:48.800
<v Speaker 1>like that happened, But apparently it did according to Shackleton's telling,

0:17:49.160 --> 0:17:52.000
<v Speaker 1>and the crew actually did manage to reach South Georgia.

0:17:52.000 --> 0:17:55.000
<v Speaker 1>According to an account by Gary Pearson, though after they

0:17:55.040 --> 0:17:58.119
<v Speaker 1>got ashore, in South Georgia. Quote at two am on

0:17:58.160 --> 0:18:01.879
<v Speaker 1>the first night ashore, Shackleton Oak, everyone shouting, look out boys,

0:18:01.920 --> 0:18:04.720
<v Speaker 1>hold on, it's going to break on us. It was

0:18:04.760 --> 0:18:09.160
<v Speaker 1>a nightmare. Shackleton thought that the black snow crested cliff

0:18:09.280 --> 0:18:13.399
<v Speaker 1>above them was a giant wave. Yeah. That that is

0:18:13.400 --> 0:18:15.520
<v Speaker 1>an impressive telling. And but yet at the same time,

0:18:15.720 --> 0:18:18.320
<v Speaker 1>you can easily go either way on it. Right, you

0:18:18.320 --> 0:18:21.040
<v Speaker 1>can say, well, all right, Shackleton is a trustworthy source

0:18:21.080 --> 0:18:23.480
<v Speaker 1>of information and this is what he saw. But then

0:18:23.480 --> 0:18:25.520
<v Speaker 1>on the other hand, we have to say he was

0:18:26.359 --> 0:18:29.119
<v Speaker 1>in an extreme situation. I mean, we've spoken before in

0:18:29.160 --> 0:18:33.280
<v Speaker 1>the show about how extreme conditionings can lead to seemingly

0:18:33.359 --> 0:18:36.399
<v Speaker 1>paranormal encounters. You know, if you've been awake for a

0:18:36.440 --> 0:18:39.239
<v Speaker 1>long time, if you're fighting for your survival, etcetera. And

0:18:39.280 --> 0:18:42.320
<v Speaker 1>all of those elements are are here. Yeah, and there

0:18:42.359 --> 0:18:44.560
<v Speaker 1>are problems with the plausibility of the story. I mean,

0:18:44.560 --> 0:18:47.240
<v Speaker 1>how did this wave not sink and kill them? Yeah,

0:18:47.320 --> 0:18:50.560
<v Speaker 1>So whatever happened obviously made an impression. Like this consummate

0:18:50.640 --> 0:18:54.359
<v Speaker 1>survivor had nightmares not of sea monsters in the deep,

0:18:54.440 --> 0:18:57.439
<v Speaker 1>but of a lone killer wave rolling up out of

0:18:57.480 --> 0:19:00.840
<v Speaker 1>the ocean as high as a mountain side. Uh. And

0:19:01.040 --> 0:19:03.479
<v Speaker 1>so one thing about giant waves like this is that

0:19:03.520 --> 0:19:07.120
<v Speaker 1>if they exist, we shouldn't have necessarily expected to hear

0:19:07.160 --> 0:19:10.360
<v Speaker 1>eyewitness accounts of them all that often in history because

0:19:10.760 --> 0:19:12.760
<v Speaker 1>of a couple of things. Number one, of course, if

0:19:12.760 --> 0:19:14.760
<v Speaker 1>they do exist, for a long time people thought them

0:19:14.800 --> 0:19:17.440
<v Speaker 1>to be very rare. But on top of that, if

0:19:17.520 --> 0:19:20.480
<v Speaker 1>sailors in the wooden ships of olden days encountered a

0:19:20.480 --> 0:19:23.320
<v Speaker 1>wave like this, uh, there was not a good chance

0:19:23.359 --> 0:19:26.080
<v Speaker 1>of them living to tell about it. Right. The goliath

0:19:26.160 --> 0:19:30.200
<v Speaker 1>wave would just arise, suddenly, kill everyone, sink the ship,

0:19:30.320 --> 0:19:32.520
<v Speaker 1>and then melt back into the sea without a trace.

0:19:32.560 --> 0:19:35.360
<v Speaker 1>How would you how would you even know it had happened. Yeah,

0:19:35.400 --> 0:19:37.760
<v Speaker 1>it would be like asking for eyewitness accounts of the

0:19:37.760 --> 0:19:41.560
<v Speaker 1>Grim Reaper. Yeah, because if if, if the reapers showing up,

0:19:41.600 --> 0:19:44.919
<v Speaker 1>But then it's probably doing its job. Yeah. But the

0:19:45.040 --> 0:19:47.639
<v Speaker 1>of course, Uh, Shackleton's story is not the only one.

0:19:47.680 --> 0:19:49.880
<v Speaker 1>There actually were a lot of stories like this. Many

0:19:50.000 --> 0:19:54.280
<v Speaker 1>mariners told these tales of a giant killer wave. In

0:19:54.320 --> 0:19:57.400
<v Speaker 1>the book Oceanography in the Days of Sale by Ian

0:19:57.480 --> 0:19:59.920
<v Speaker 1>Jones and Joyce Jones, the author is right about the

0:20:00.040 --> 0:20:04.520
<v Speaker 1>French naval explorer and scientists Dumont d'Urville and his his

0:20:04.640 --> 0:20:08.080
<v Speaker 1>disputes with the French scientists Francois Arago about the upper

0:20:08.119 --> 0:20:11.480
<v Speaker 1>limits of wave height quote when the astrolabe and that

0:20:11.560 --> 0:20:15.600
<v Speaker 1>was Derville ship. When the astrolabe in eighteen twenty six

0:20:15.640 --> 0:20:18.119
<v Speaker 1>was making its way across the southern stretches of the

0:20:18.160 --> 0:20:21.679
<v Speaker 1>Indian Ocean, it encountered a gale with mountainous seas in

0:20:21.680 --> 0:20:25.719
<v Speaker 1>which a man was lost overboard. Dumont d'Urville, in his narrative,

0:20:25.760 --> 0:20:28.320
<v Speaker 1>expressed the opinion that the waves reached a height of

0:20:28.640 --> 0:20:31.560
<v Speaker 1>at least eighty to a hundred feet in an era

0:20:31.640 --> 0:20:34.639
<v Speaker 1>when opinions were being expressed that no wave would exceed

0:20:34.760 --> 0:20:39.000
<v Speaker 1>thirty feet. Dumont d'urville's estimations were received, it seemed, with

0:20:39.160 --> 0:20:44.200
<v Speaker 1>some skepticism and France, while Arago rejected and even ridiculed

0:20:44.280 --> 0:20:48.159
<v Speaker 1>Derville's claim. Basically, you know this is just a semen's fancy. Uh.

0:20:48.480 --> 0:20:51.760
<v Speaker 1>He referred in writing to the quote truly prodigious waves

0:20:51.800 --> 0:20:55.560
<v Speaker 1>with which the lively imagination of certain navigators delights in

0:20:55.680 --> 0:20:58.840
<v Speaker 1>covering the seas. That sounded like a burn. That was

0:20:58.880 --> 0:21:00.399
<v Speaker 1>a bit of a burn. I think Yeah, I think

0:21:00.440 --> 0:21:02.879
<v Speaker 1>he was being a bit dismissive here, but maybe we

0:21:02.880 --> 0:21:04.719
<v Speaker 1>should take a break and then we come back. We

0:21:04.760 --> 0:21:08.240
<v Speaker 1>can talk about some physical evidence that actually points to

0:21:08.280 --> 0:21:13.880
<v Speaker 1>the existence of waves like this. Thank alright, we're back.

0:21:13.920 --> 0:21:19.600
<v Speaker 1>We've we've discussed accounts anecdotal evidence of giant waves, of

0:21:19.720 --> 0:21:23.159
<v Speaker 1>freak waves, of rogue waves. But now we're going to

0:21:23.240 --> 0:21:26.320
<v Speaker 1>get into what the science has to say. What what

0:21:26.480 --> 0:21:30.600
<v Speaker 1>kind of proof is there, if any, to substantiate these claims, Right,

0:21:30.720 --> 0:21:32.960
<v Speaker 1>you'd want some kind of physical evidence other than just

0:21:33.000 --> 0:21:35.760
<v Speaker 1>people saying they saw a giant wave, because people say

0:21:35.800 --> 0:21:38.560
<v Speaker 1>they saw all sorts of things. But uh, you know, ultimately,

0:21:39.240 --> 0:21:40.760
<v Speaker 1>this is why we have science. This is why we

0:21:40.800 --> 0:21:44.040
<v Speaker 1>have a recording equipment. This is so we can actually

0:21:44.119 --> 0:21:48.080
<v Speaker 1>validate that that waves of this nature exists. Yeah, and

0:21:48.080 --> 0:21:50.640
<v Speaker 1>so we talked about the French scientists France while Rago

0:21:51.680 --> 0:21:55.399
<v Speaker 1>being severely doubting that waves like this existed. And from

0:21:55.440 --> 0:21:57.560
<v Speaker 1>a scientific point of view, there had long been reason

0:21:57.680 --> 0:22:00.960
<v Speaker 1>to doubt these accounts of gigantic monster or waves. Not

0:22:01.080 --> 0:22:03.520
<v Speaker 1>that it was impossible for a giant wave to exist,

0:22:03.640 --> 0:22:06.680
<v Speaker 1>but that monstrous waves of the kind reported by mariners,

0:22:06.760 --> 0:22:08.440
<v Speaker 1>you know, the kind that would cause some of the

0:22:08.520 --> 0:22:12.120
<v Speaker 1>damage attributed to them. They were thought to only come

0:22:12.160 --> 0:22:14.600
<v Speaker 1>about on the scale of maybe once in hundreds or

0:22:14.600 --> 0:22:17.160
<v Speaker 1>thousands of years. You know, it's like the thousand year

0:22:17.200 --> 0:22:20.199
<v Speaker 1>storm kind of thing. So like every thousand years a

0:22:20.240 --> 0:22:22.560
<v Speaker 1>wave like this might occur, but then then just might

0:22:22.600 --> 0:22:24.840
<v Speaker 1>not be people around to see it. Yeah, exactly. So

0:22:24.920 --> 0:22:26.919
<v Speaker 1>you know, you've got this question where Shackleton and all

0:22:26.960 --> 0:22:30.960
<v Speaker 1>these others exaggerating, hallucinating misremembering was this the was the

0:22:30.960 --> 0:22:34.680
<v Speaker 1>mountain that flows like a mermaid or something. So I mean,

0:22:34.720 --> 0:22:36.960
<v Speaker 1>on one hand, you have that argument, right that maybe

0:22:36.960 --> 0:22:39.560
<v Speaker 1>they're just not occurring enough for anyone to ever see them.

0:22:39.800 --> 0:22:42.520
<v Speaker 1>So it doesn't seem right that we have numerous accounts

0:22:42.960 --> 0:22:45.840
<v Speaker 1>um where where people say they witnessed them. But of

0:22:45.880 --> 0:22:47.320
<v Speaker 1>course we also have to consider that, you know the

0:22:47.359 --> 0:22:49.800
<v Speaker 1>fact that ships and seamen again have always gone missing

0:22:49.880 --> 0:22:52.680
<v Speaker 1>like this. You look to the uh, the sheer number

0:22:52.680 --> 0:22:57.119
<v Speaker 1>of shipwrecks, you look to accounts of human activities on

0:22:57.480 --> 0:23:01.160
<v Speaker 1>the sea. Ships have always sunctions, have always encountered bad

0:23:01.200 --> 0:23:05.800
<v Speaker 1>weather or various other uh, you know, things that would

0:23:05.880 --> 0:23:08.960
<v Speaker 1>cause them to perish. Yeah, and another thing we should

0:23:09.000 --> 0:23:12.199
<v Speaker 1>think about is that ships sink and disappear at a

0:23:12.359 --> 0:23:15.560
<v Speaker 1>rate that would absolutely set our hair on fire if

0:23:15.600 --> 0:23:18.320
<v Speaker 1>it was like airplanes or something. You know, if there's

0:23:18.359 --> 0:23:21.640
<v Speaker 1>like one major airline crash, people freak out, but ships

0:23:21.680 --> 0:23:25.119
<v Speaker 1>go missing or sink all the time. Yeah, I was

0:23:25.160 --> 0:23:28.000
<v Speaker 1>looking around for some stats on this and today and again,

0:23:28.040 --> 0:23:31.120
<v Speaker 1>as humans command the sea more than ever before, more

0:23:31.160 --> 0:23:33.000
<v Speaker 1>ships are on the sea than than at any point

0:23:33.280 --> 0:23:36.520
<v Speaker 1>in human history, and we're looking at a loss of

0:23:36.560 --> 0:23:39.720
<v Speaker 1>something like a hundred large vessels every year. Yeah, it's

0:23:39.720 --> 0:23:42.080
<v Speaker 1>about an average. Yeah, Yeah, I've seen it all since.

0:23:42.080 --> 0:23:44.680
<v Speaker 1>The stat also thrown out there that it basically amounts

0:23:44.680 --> 0:23:48.200
<v Speaker 1>to two vessels per week, and that's just large vessels.

0:23:48.280 --> 0:23:50.560
<v Speaker 1>When you add in smaller vessels, it's even more. Yeah.

0:23:50.600 --> 0:23:51.840
<v Speaker 1>And now, and of course, some of these are gonna

0:23:51.840 --> 0:23:54.239
<v Speaker 1>be clear cases right where they say, oh, you know

0:23:54.320 --> 0:23:57.560
<v Speaker 1>this was the ships sunk because you know, it ran

0:23:57.600 --> 0:24:00.320
<v Speaker 1>aground here, some sort of a collision here, etcetera. But

0:24:00.359 --> 0:24:02.680
<v Speaker 1>in other cases it could inevitably remain a mystery. Is

0:24:02.720 --> 0:24:05.080
<v Speaker 1>just you know, a case by case scenario. So we

0:24:05.119 --> 0:24:08.239
<v Speaker 1>have to ask these cases of the mysterious cases, uh,

0:24:08.320 --> 0:24:10.399
<v Speaker 1>the very sort of case that may have led to

0:24:10.720 --> 0:24:14.639
<v Speaker 1>various nautical superstitions like the Bermuda triangle. Uh and then

0:24:14.720 --> 0:24:18.800
<v Speaker 1>an olden times sea monsters. Could these be due to

0:24:19.080 --> 0:24:22.040
<v Speaker 1>some manner of rogue wave? Yeah, exactly. And so to

0:24:22.080 --> 0:24:25.080
<v Speaker 1>answer that question, I think one good thing, just one

0:24:25.119 --> 0:24:27.920
<v Speaker 1>good place to start, and where people did look for

0:24:27.960 --> 0:24:31.840
<v Speaker 1>a long time was for physical evidence of damage caused

0:24:31.840 --> 0:24:34.960
<v Speaker 1>by rogue waves. Yeah and uh. And for the longest

0:24:35.000 --> 0:24:38.200
<v Speaker 1>we simply didn't have any solid evidence and we didn't

0:24:38.200 --> 0:24:40.679
<v Speaker 1>have any evidence of them, a solid evidence of them occurring.

0:24:40.720 --> 0:24:43.800
<v Speaker 1>We didn't have footage or anything. Uh. So all we

0:24:43.920 --> 0:24:46.919
<v Speaker 1>still had were just those, um those various bits of

0:24:46.920 --> 0:24:51.399
<v Speaker 1>anecdotal and from anecdotal evidence and then experts weighing in

0:24:51.480 --> 0:24:54.160
<v Speaker 1>on what seemed possible and likely. But of course, if

0:24:54.160 --> 0:24:57.080
<v Speaker 1>waves like this were occurring, they should in some ways

0:24:57.200 --> 0:24:59.639
<v Speaker 1>cause damage that we should be able to see and

0:24:59.680 --> 0:25:04.080
<v Speaker 1>detect act because, I mean, what water is amazingly powerful. People,

0:25:04.560 --> 0:25:07.280
<v Speaker 1>we do not have good intuitions about the physical power

0:25:07.320 --> 0:25:10.320
<v Speaker 1>of moving water. Uh. This may come from our experience,

0:25:10.359 --> 0:25:13.879
<v Speaker 1>like swimming for pleasure or splashing in a bathtub. You know,

0:25:13.920 --> 0:25:17.800
<v Speaker 1>we're moving water just glides gently and gracefully around the body,

0:25:17.880 --> 0:25:20.840
<v Speaker 1>causing no harm at all. But our intuitions about water

0:25:20.960 --> 0:25:25.800
<v Speaker 1>really fail when we encounter large masses of fast moving fluids.

0:25:25.840 --> 0:25:28.320
<v Speaker 1>Like the way people behave in flash floods is a

0:25:28.320 --> 0:25:30.680
<v Speaker 1>great example of this. You will a lot of times

0:25:30.680 --> 0:25:34.080
<v Speaker 1>see people who appear to think they can just wade

0:25:34.200 --> 0:25:38.359
<v Speaker 1>through knee high moving floodwaters, only to discover tragically that

0:25:38.400 --> 0:25:40.960
<v Speaker 1>it just washes you away instantly, or in any case

0:25:41.080 --> 0:25:43.680
<v Speaker 1>they think they can drive through. Oh yeah, and and

0:25:43.720 --> 0:25:46.720
<v Speaker 1>it's tragic, but it it's It reflects the fact that

0:25:46.760 --> 0:25:50.119
<v Speaker 1>our intuitions about the power of moving water are not good.

0:25:50.160 --> 0:25:53.480
<v Speaker 1>We underestimate it. Likewise with giant waves. You know, we

0:25:53.800 --> 0:25:55.679
<v Speaker 1>may be used to playing in the surf on a

0:25:55.720 --> 0:25:58.560
<v Speaker 1>beach vacation or something where the waves are harmless. They're fun,

0:25:58.640 --> 0:26:01.720
<v Speaker 1>you can glide with pleasure or over each peak and trough.

0:26:01.840 --> 0:26:05.440
<v Speaker 1>But sufficiently huge walls of moving water that are moving

0:26:05.720 --> 0:26:08.199
<v Speaker 1>fast can act more or less like huge walls of

0:26:08.240 --> 0:26:12.120
<v Speaker 1>concrete smashing right into you at speed, just like tsunamis

0:26:12.160 --> 0:26:14.720
<v Speaker 1>can you know, tear down solid buildings and trees. A

0:26:14.760 --> 0:26:17.360
<v Speaker 1>giant wave of crashing into a ship or a structure

0:26:17.440 --> 0:26:21.080
<v Speaker 1>can cause devastating physical damage. It hits, it moves, it

0:26:21.160 --> 0:26:24.320
<v Speaker 1>twists the structure. I mean it, it's like a hand

0:26:24.359 --> 0:26:27.760
<v Speaker 1>of a god indeed, and besides a heavy hitter. Yeah.

0:26:27.840 --> 0:26:30.119
<v Speaker 1>So if you ask, was there ever physical damage that

0:26:30.160 --> 0:26:33.760
<v Speaker 1>would indicate the existence of seemingly impossible rogue waves, like

0:26:34.440 --> 0:26:37.760
<v Speaker 1>before we had direct records of one, I think the

0:26:37.760 --> 0:26:40.080
<v Speaker 1>answer is yes, there were. There were some very chilling

0:26:40.119 --> 0:26:44.000
<v Speaker 1>and mysterious clues left in the wreckage of battered ships

0:26:44.080 --> 0:26:47.080
<v Speaker 1>and structures in or near the water. Uh. There there

0:26:47.080 --> 0:26:50.960
<v Speaker 1>are stories going way back to like waves crashing against

0:26:51.119 --> 0:26:54.320
<v Speaker 1>lighthouses that that are so far up off the water

0:26:54.720 --> 0:26:57.680
<v Speaker 1>it seems impossible that like a wave could have damaged them.

0:26:57.680 --> 0:27:00.520
<v Speaker 1>You know, lighthouses more than a hundred feet up off

0:27:00.560 --> 0:27:04.639
<v Speaker 1>the normal waterline, with windows smashed out and stuff like that,

0:27:04.680 --> 0:27:08.160
<v Speaker 1>and you'd be like, how did that happen? In N two,

0:27:09.000 --> 0:27:13.080
<v Speaker 1>the mobile offshore drilling platform, the Ocean Ranger, was apparently

0:27:13.160 --> 0:27:16.080
<v Speaker 1>damaged by a giant wave off the coast of Canada.

0:27:16.160 --> 0:27:19.840
<v Speaker 1>Its sustained damage to its ballast control room, which only

0:27:19.880 --> 0:27:22.160
<v Speaker 1>could have happened if there was an extremely high wave,

0:27:22.240 --> 0:27:24.320
<v Speaker 1>and this led to a chain reaction of events that

0:27:24.720 --> 0:27:27.840
<v Speaker 1>caused the platform to sink and tragically all eighty four

0:27:27.880 --> 0:27:30.800
<v Speaker 1>crew members died. Everyone aboard died when this thing sank.

0:27:31.200 --> 0:27:33.240
<v Speaker 1>But there were also there there have been stories all

0:27:33.240 --> 0:27:36.560
<v Speaker 1>throughout the twentieth century of like ocean liners about you know,

0:27:36.640 --> 0:27:41.440
<v Speaker 1>passenger vessels and cargo vessels and naval vessels that would

0:27:41.480 --> 0:27:44.040
<v Speaker 1>report being suddenly hit by a giant wave that the

0:27:44.200 --> 0:27:46.360
<v Speaker 1>just ricked havoc upon the ship. You know, it would

0:27:46.440 --> 0:27:49.199
<v Speaker 1>damage the bridge, it would rip off the mast and rigging.

0:27:49.240 --> 0:27:52.480
<v Speaker 1>Sometimes it would rip away lifeboats that were like you know,

0:27:52.560 --> 0:27:55.960
<v Speaker 1>had steel bolts holding them in place. Things that wouldn't

0:27:55.960 --> 0:27:58.639
<v Speaker 1>make sense if it was just rocking in normal bad weather.

0:27:59.040 --> 0:28:02.280
<v Speaker 1>But even with all this physical evidence of of structures

0:28:02.320 --> 0:28:06.040
<v Speaker 1>and ships being hit by these powerful events, it will

0:28:06.119 --> 0:28:09.080
<v Speaker 1>still be hard to meassure and confirm the existence of

0:28:09.119 --> 0:28:12.720
<v Speaker 1>these giant rogue waves firsthand, because number one, you can't

0:28:12.760 --> 0:28:15.280
<v Speaker 1>predict in advance when one will appear, Like there are

0:28:15.280 --> 0:28:19.119
<v Speaker 1>obviously better places and times to look for them, but

0:28:19.240 --> 0:28:21.520
<v Speaker 1>you can't know when one's going to happen or where.

0:28:21.960 --> 0:28:24.840
<v Speaker 1>And then if when one does show up, you suddenly

0:28:24.880 --> 0:28:28.119
<v Speaker 1>have a number of priorities, yeah, exactly ahead of perhaps

0:28:28.119 --> 0:28:30.639
<v Speaker 1>recording it. And that being said, we are increasingly in

0:28:31.200 --> 0:28:34.200
<v Speaker 1>an age of just ubiquitous recording equipment. So who knows

0:28:34.280 --> 0:28:36.960
<v Speaker 1>what the very near future will bring. Yeah, and so

0:28:37.040 --> 0:28:39.640
<v Speaker 1>when one does appear that there's generally not time to

0:28:39.720 --> 0:28:41.800
<v Speaker 1>react and track and observe it, like you're saying, it's

0:28:41.840 --> 0:28:44.720
<v Speaker 1>just there, and then within a few seconds you will

0:28:44.840 --> 0:28:47.800
<v Speaker 1>very possibly be dead. So the key here really is

0:28:47.880 --> 0:28:51.680
<v Speaker 1>to to not, of course, not just depend on eyewitness accounts,

0:28:51.680 --> 0:28:53.760
<v Speaker 1>which we already had, and of course there's an inherent

0:28:53.800 --> 0:28:56.600
<v Speaker 1>problem there, uh, and we can't go looking for them,

0:28:57.080 --> 0:29:00.360
<v Speaker 1>uh per se because their difficulties there. What you need

0:29:00.720 --> 0:29:05.800
<v Speaker 1>are essentially machine recordings, passive detections, some sort of detection

0:29:05.880 --> 0:29:09.200
<v Speaker 1>system that that will say, it will tell you like

0:29:09.280 --> 0:29:12.040
<v Speaker 1>what what sort of wave activity is occurring near a

0:29:12.040 --> 0:29:16.080
<v Speaker 1>given vessel or a near a given offshore platform and

0:29:16.120 --> 0:29:18.800
<v Speaker 1>one that is lucky or unlucky enough to catch one

0:29:18.880 --> 0:29:21.480
<v Speaker 1>in the act. And so the history of rogue wave

0:29:21.480 --> 0:29:25.360
<v Speaker 1>of science I think really changed in nine right, because

0:29:25.360 --> 0:29:28.440
<v Speaker 1>that's when we finally did get this this sort of evidence.

0:29:28.760 --> 0:29:33.600
<v Speaker 1>So it was January one in the North Sea, uh,

0:29:33.720 --> 0:29:39.000
<v Speaker 1>the North Sea platform drop Ner, which is a gas platform.

0:29:39.080 --> 0:29:41.640
<v Speaker 1>This is built in nineteen eighty four and it consists

0:29:41.640 --> 0:29:44.560
<v Speaker 1>of seven risers and even today it's an important complex

0:29:44.560 --> 0:29:47.560
<v Speaker 1>in the Norwegian oil industry. So this would be situated

0:29:47.600 --> 0:29:51.480
<v Speaker 1>like in the North Sea between Norway and Scotland. Basically, yeah,

0:29:51.520 --> 0:29:53.400
<v Speaker 1>so what's your you know, this is like these are

0:29:53.480 --> 0:29:57.840
<v Speaker 1>rough seas. Yeah, But on this particular day, equipment aboard

0:29:57.880 --> 0:30:03.240
<v Speaker 1>the platform, namely a downward look laser recorded a monster

0:30:03.360 --> 0:30:07.000
<v Speaker 1>of a wave, so significant wave height in the area.

0:30:07.600 --> 0:30:09.760
<v Speaker 1>This is just like the average sort of wave height

0:30:09.880 --> 0:30:13.200
<v Speaker 1>that was occurring was already twelve meters or thirty nine

0:30:13.240 --> 0:30:17.240
<v Speaker 1>point thirty seven feet. Okay, so everything was already like really,

0:30:17.280 --> 0:30:19.920
<v Speaker 1>that's that sounds horrible. I would not I wouldn't want

0:30:19.920 --> 0:30:21.440
<v Speaker 1>to be anywhere near that. You know, you don't want

0:30:21.440 --> 0:30:25.080
<v Speaker 1>to take your James Carrot out on that, right. But then,

0:30:25.320 --> 0:30:28.120
<v Speaker 1>according to the data, a wave rolled in that was

0:30:28.200 --> 0:30:32.080
<v Speaker 1>twenty five point six meters high or a three point

0:30:32.160 --> 0:30:36.680
<v Speaker 1>nine feet Now, as is often the case, you you

0:30:36.760 --> 0:30:39.360
<v Speaker 1>might just hear a number and it might not mean

0:30:39.400 --> 0:30:42.000
<v Speaker 1>anything to you, but do your best to stop for

0:30:42.040 --> 0:30:44.960
<v Speaker 1>a second here and picture it. Yeah, we're talking a

0:30:45.160 --> 0:30:49.520
<v Speaker 1>seven story building of a wave and uh, and it's

0:30:49.560 --> 0:30:52.960
<v Speaker 1>coming at the platform and indeed the platform sustained Uh,

0:30:53.160 --> 0:30:57.000
<v Speaker 1>minor damage, luckily, but that damage was enough to to

0:30:57.360 --> 0:30:59.680
<v Speaker 1>verify the reality of the wave. So, in other words,

0:30:59.680 --> 0:31:02.800
<v Speaker 1>showing that this wasn't just a recording anomaly where you know,

0:31:02.840 --> 0:31:06.800
<v Speaker 1>the laser went wonky or something a seagull flew undwritten

0:31:07.400 --> 0:31:10.239
<v Speaker 1>or whatever would cause it to to to produce some

0:31:10.320 --> 0:31:12.760
<v Speaker 1>sort of an anomaly. Uh No, we also have the

0:31:12.760 --> 0:31:15.760
<v Speaker 1>physical damage to the structure to back up what happened. Yeah,

0:31:15.800 --> 0:31:18.760
<v Speaker 1>so they've got the they've got the accurate scientific reading

0:31:18.880 --> 0:31:22.320
<v Speaker 1>from this instrument, and they've got corroborating evidence. So it

0:31:22.400 --> 0:31:24.920
<v Speaker 1>wasn't just a freak measurement. It was in fact a

0:31:24.960 --> 0:31:29.920
<v Speaker 1>freak wave, a rogue wave. And so in the first

0:31:30.000 --> 0:31:32.920
<v Speaker 1>day of the new year, we entered an era in

0:31:32.920 --> 0:31:36.120
<v Speaker 1>which the rogue wave was no longer purely a myth.

0:31:36.360 --> 0:31:39.640
<v Speaker 1>It was a reality. And from there we enter the

0:31:39.680 --> 0:31:43.479
<v Speaker 1>decades of figuring out, well, what's the frequency, what's the cause,

0:31:44.040 --> 0:31:47.320
<v Speaker 1>and ultimately what is the risk. Yeah, now, so you

0:31:47.400 --> 0:31:49.880
<v Speaker 1>might ask the question, Okay, we've just been talking about

0:31:49.920 --> 0:31:52.840
<v Speaker 1>big waves, what is a rogue wave? Technically I think

0:31:52.880 --> 0:31:55.320
<v Speaker 1>I alluded to this earlier, but a rogue wave is

0:31:55.360 --> 0:31:58.520
<v Speaker 1>defined in relative terms, right, So it's a wave that's

0:31:58.760 --> 0:32:02.600
<v Speaker 1>greater than twice the size of all the other waves

0:32:02.640 --> 0:32:05.480
<v Speaker 1>in the same area at the same time. Uh. And yes,

0:32:05.520 --> 0:32:08.560
<v Speaker 1>a rogue waves do occur even in the context of

0:32:08.760 --> 0:32:12.160
<v Speaker 1>very powerful regular wave patterns. So even in places where

0:32:12.160 --> 0:32:14.800
<v Speaker 1>the waves are unusually high and choppy, you can get

0:32:14.800 --> 0:32:17.080
<v Speaker 1>these things that stand out that are more than twice

0:32:17.120 --> 0:32:20.160
<v Speaker 1>as tall as the other waves around them. Because again

0:32:20.200 --> 0:32:23.440
<v Speaker 1>this North Sea example, like, those were some pretty tall waves.

0:32:23.680 --> 0:32:25.640
<v Speaker 1>I mean, what are we talking earlier about, um in

0:32:26.000 --> 0:32:29.280
<v Speaker 1>about earlier experts thinking that like thirty feet was more

0:32:29.320 --> 0:32:32.200
<v Speaker 1>or less the limited. Yeah, that that was long believed

0:32:32.200 --> 0:32:34.480
<v Speaker 1>to be about where waves capped off at least in

0:32:34.520 --> 0:32:36.880
<v Speaker 1>the kind of conditions you'd expect every year. Right, and

0:32:36.920 --> 0:32:39.520
<v Speaker 1>so the the just the ambient wave height in the

0:32:39.600 --> 0:32:42.800
<v Speaker 1>in the area was already uh, in excess of that. Now,

0:32:42.840 --> 0:32:45.959
<v Speaker 1>I guess maybe we should talk about how rogue waves

0:32:46.040 --> 0:32:49.920
<v Speaker 1>exactly cause damage to ships, right, because there there are

0:32:50.000 --> 0:32:53.240
<v Speaker 1>multiple waves that being hit by this flowing mountain, this

0:32:53.360 --> 0:32:56.680
<v Speaker 1>giant wall of water can sink you and destroy you.

0:32:57.720 --> 0:33:00.440
<v Speaker 1>Of course, any time a ship is hit by a wave,

0:33:00.520 --> 0:33:03.760
<v Speaker 1>it's physical structure can just be directly damaged by like

0:33:03.840 --> 0:33:06.800
<v Speaker 1>the force of the impact and this is this is

0:33:06.880 --> 0:33:10.680
<v Speaker 1>especially relevant to the superstructure of a ship's superstructure is

0:33:10.720 --> 0:33:13.400
<v Speaker 1>what you call all that stuff that's sticking up off

0:33:13.480 --> 0:33:16.000
<v Speaker 1>the top of the hull, like the mast, the rigging,

0:33:16.120 --> 0:33:19.880
<v Speaker 1>the bridge, the lifeboats. It can all be smashed two

0:33:19.920 --> 0:33:23.080
<v Speaker 1>bits or ripped apart. And of course a lake's worth

0:33:23.080 --> 0:33:25.000
<v Speaker 1>of water is going to wash over the top of

0:33:25.000 --> 0:33:27.080
<v Speaker 1>the vessel. And if there's a wave for the vessel

0:33:27.120 --> 0:33:30.040
<v Speaker 1>to take this water on, it very well can do that.

0:33:30.400 --> 0:33:32.479
<v Speaker 1>So that's your first problem. And I think that's an

0:33:32.480 --> 0:33:34.760
<v Speaker 1>easy one to miss because again, like you said, we

0:33:34.760 --> 0:33:37.080
<v Speaker 1>we just we often don't think about just the sheer

0:33:37.480 --> 0:33:39.640
<v Speaker 1>punch of that water, especially when it is like a

0:33:40.800 --> 0:33:44.360
<v Speaker 1>fist the size of of of lake's worth of water. Yeah. Well,

0:33:44.680 --> 0:33:47.040
<v Speaker 1>just imagine you are standing in the bridge of the

0:33:47.080 --> 0:33:49.600
<v Speaker 1>ship and this wall of water comes across you. So

0:33:49.640 --> 0:33:52.720
<v Speaker 1>it washes over the hull, it washes over the deck,

0:33:53.080 --> 0:33:55.600
<v Speaker 1>and it smashes into the bridge. And what what very

0:33:55.600 --> 0:33:57.560
<v Speaker 1>well could happen there is if you know, if the

0:33:57.560 --> 0:33:59.920
<v Speaker 1>bridge is not in some significant way destroyed, it may

0:34:00.040 --> 0:34:02.320
<v Speaker 1>well smashed through all the windows and throw all that

0:34:02.480 --> 0:34:05.920
<v Speaker 1>glass at you and wash into the bridge. But so

0:34:06.040 --> 0:34:08.359
<v Speaker 1>if it hits a ship laterally, like hits a ship

0:34:08.360 --> 0:34:10.960
<v Speaker 1>on the side, the ship can be capsized to buy

0:34:10.960 --> 0:34:13.919
<v Speaker 1>a rogue wave, flipped over on its side or upside down,

0:34:13.960 --> 0:34:15.920
<v Speaker 1>which of course can lead to foundering. You don't want

0:34:15.920 --> 0:34:18.800
<v Speaker 1>your ship sideways, um if it gets If a ship

0:34:18.840 --> 0:34:22.200
<v Speaker 1>gets hit head on by a rogue wave, this can

0:34:22.239 --> 0:34:25.120
<v Speaker 1>also harm. It caused major problems. It can lead to

0:34:25.239 --> 0:34:28.120
<v Speaker 1>the bow or the stern or the ship being lifted

0:34:28.200 --> 0:34:30.399
<v Speaker 1>in an angle up out of the water. And if

0:34:30.400 --> 0:34:33.760
<v Speaker 1>it's a large ship, this can be really dangerous because Robert,

0:34:33.760 --> 0:34:36.200
<v Speaker 1>you remember that scene in Titanic, you know where the

0:34:36.200 --> 0:34:40.280
<v Speaker 1>ship starts sinking from the bow in and the stern

0:34:40.360 --> 0:34:42.840
<v Speaker 1>of the boat is lifted up at an angle in

0:34:42.880 --> 0:34:47.160
<v Speaker 1>the air. Shipholes are extremely heavy and they're not designed

0:34:47.560 --> 0:34:51.400
<v Speaker 1>to withstand sheer stresses on the hull of that immensity,

0:34:51.480 --> 0:34:54.400
<v Speaker 1>Like the structure can't support half of the way to

0:34:54.440 --> 0:34:57.400
<v Speaker 1>the ship hanging up in the air. So the Titanic,

0:34:57.440 --> 0:35:00.400
<v Speaker 1>of course kind of cracked like a celery stalk. I

0:35:00.480 --> 0:35:03.640
<v Speaker 1>think I was reading that. The main theory now is

0:35:03.680 --> 0:35:05.640
<v Speaker 1>that the crack started at the bottom at a week

0:35:05.719 --> 0:35:08.080
<v Speaker 1>point along the base of the ship, and then it

0:35:08.160 --> 0:35:10.520
<v Speaker 1>just cracked off, and then the bow sank, and then

0:35:10.560 --> 0:35:12.879
<v Speaker 1>the stern bobbed for a bit and then sank as well.

0:35:13.400 --> 0:35:16.840
<v Speaker 1>But of course giant waves can cause other large ships

0:35:16.880 --> 0:35:19.480
<v Speaker 1>to do the same. So if the wave washes over you,

0:35:19.480 --> 0:35:21.680
<v Speaker 1>you can end up with one end of the ship

0:35:21.800 --> 0:35:24.359
<v Speaker 1>sort of lifted poking up out of the water as

0:35:24.400 --> 0:35:27.880
<v Speaker 1>it comes out of this wave motion, and that stress

0:35:27.920 --> 0:35:31.279
<v Speaker 1>can crack or or otherwise significantly damaged the hull, which

0:35:31.280 --> 0:35:33.520
<v Speaker 1>of course again can make you sink. So there there

0:35:33.560 --> 0:35:36.080
<v Speaker 1>are a lot of ways that a giant wave can

0:35:36.120 --> 0:35:38.040
<v Speaker 1>mess you up. You just don't want them at all.

0:35:38.360 --> 0:35:40.120
<v Speaker 1>All Right, we're gonna take one more break. When we

0:35:40.200 --> 0:35:42.480
<v Speaker 1>come back, we're gonna discuss some of the causes for

0:35:42.600 --> 0:35:46.880
<v Speaker 1>rogue waves and also a very recent paper that explored

0:35:47.239 --> 0:35:49.560
<v Speaker 1>the question just how often are these occurring and how

0:35:49.600 --> 0:35:54.359
<v Speaker 1>powerful are they? All Right, we're back. So we're looking

0:35:54.400 --> 0:35:57.480
<v Speaker 1>at the question first of what causes rogue waves, and

0:35:57.520 --> 0:35:59.799
<v Speaker 1>this is not a fully settled question. I think that

0:35:59.840 --> 0:36:03.840
<v Speaker 1>there are some, uh some competing and not necessarily mutually

0:36:03.880 --> 0:36:07.680
<v Speaker 1>exclusive hypotheses here, right, So first let's go back to

0:36:07.719 --> 0:36:10.279
<v Speaker 1>the dropping or wave for a moment. According to the

0:36:10.320 --> 0:36:17.040
<v Speaker 1>European Center for Medium range weather forecasts, high resolution retrospective forecasts, forecasts,

0:36:17.080 --> 0:36:22.680
<v Speaker 1>I mean's going backwards in time retrocasts. UM. Quote suggests

0:36:22.680 --> 0:36:27.040
<v Speaker 1>that waves driven by a southward moving polar low interacted

0:36:27.160 --> 0:36:30.840
<v Speaker 1>with a substantial local wind generated wave system to produce

0:36:30.880 --> 0:36:34.960
<v Speaker 1>the conditions conducive to the observed large rogue wave. And

0:36:35.000 --> 0:36:38.640
<v Speaker 1>that's from work by Bitlow at all. Okay, so that's

0:36:38.680 --> 0:36:43.080
<v Speaker 1>saying that there are there were conflicting wave patterns that

0:36:43.080 --> 0:36:45.840
<v Speaker 1>that came together in a way that they think created

0:36:45.920 --> 0:36:48.319
<v Speaker 1>this massive wave. It was something about the way that

0:36:48.360 --> 0:36:52.439
<v Speaker 1>these two different patterns interacted when they when they crashed together. Right.

0:36:52.480 --> 0:36:56.520
<v Speaker 1>And you know, again storm systems, weather and the movement

0:36:56.560 --> 0:36:58.480
<v Speaker 1>to the ocean. These are complex systems that are often

0:36:58.480 --> 0:37:02.279
<v Speaker 1>difficult force to understand. I think we can all understand

0:37:02.360 --> 0:37:05.920
<v Speaker 1>the power of convergence, you know, when you have have

0:37:06.600 --> 0:37:09.520
<v Speaker 1>I mean, we see this is something that's understandable about whether, right,

0:37:09.640 --> 0:37:12.120
<v Speaker 1>we have two fronts coming together. Um, you know, we

0:37:12.160 --> 0:37:15.080
<v Speaker 1>realize that can be bad news. Um and uh, and

0:37:15.120 --> 0:37:18.560
<v Speaker 1>so it's seemingly we've had a similar situation here. Um,

0:37:19.160 --> 0:37:23.560
<v Speaker 1>there's two energetic systems coming together and it creates conditions

0:37:23.560 --> 0:37:26.480
<v Speaker 1>that are optimal for this extra large wave to rise

0:37:26.520 --> 0:37:28.080
<v Speaker 1>up out of the sea. And I'll talk more about

0:37:28.120 --> 0:37:31.239
<v Speaker 1>stuff like that in just a minute. They also point

0:37:31.280 --> 0:37:35.920
<v Speaker 1>to the work of cavalry at all from and they

0:37:35.920 --> 0:37:38.120
<v Speaker 1>point out that also that we shouldn't think of rogue

0:37:38.120 --> 0:37:42.960
<v Speaker 1>waves as ultrawere altra rare once a generation occurrences. Rather quote,

0:37:43.080 --> 0:37:45.600
<v Speaker 1>such waves are a regular part of large storms and

0:37:45.680 --> 0:37:48.640
<v Speaker 1>coming across them is just a matter of probability, depending

0:37:48.680 --> 0:37:51.920
<v Speaker 1>on the spatial and temporal scales considered. So the dropping

0:37:51.920 --> 0:37:55.040
<v Speaker 1>a wave was probably a result of these two crossing

0:37:55.120 --> 0:37:59.120
<v Speaker 1>low frequency wave systems, and it's it's, it's and it

0:37:59.200 --> 0:38:02.319
<v Speaker 1>may be more calm than we initially thought, especially with

0:38:02.400 --> 0:38:06.000
<v Speaker 1>fast moving storms. Yeah, so what exactly is like the

0:38:06.000 --> 0:38:09.600
<v Speaker 1>physical mechanism that causes them in these situations, Well, that's

0:38:09.640 --> 0:38:12.160
<v Speaker 1>still being investigated. But there do appear to be several

0:38:12.239 --> 0:38:15.200
<v Speaker 1>potential causes and explanations. Like I said, I think these

0:38:15.239 --> 0:38:18.640
<v Speaker 1>are not mutually exclusive, like some might explain some rogue

0:38:18.640 --> 0:38:21.960
<v Speaker 1>waves and others might explain others. According to the n

0:38:22.000 --> 0:38:24.160
<v Speaker 1>o A, A picks out a couple of main ones

0:38:24.239 --> 0:38:28.040
<v Speaker 1>that it identifies as as the primary candidates. One is

0:38:28.160 --> 0:38:32.000
<v Speaker 1>wave interference. So when you study the propagation of waves,

0:38:32.000 --> 0:38:33.880
<v Speaker 1>and this is not just waves in water. This is

0:38:33.920 --> 0:38:38.120
<v Speaker 1>waves of all kinds like electromagnetic radiation waves, sound waves,

0:38:38.160 --> 0:38:41.600
<v Speaker 1>waves through matter like like you see in water. When

0:38:41.640 --> 0:38:44.320
<v Speaker 1>you see these uh, when you look at the propagation

0:38:44.360 --> 0:38:45.960
<v Speaker 1>of these types of waves, you begin to see that

0:38:46.040 --> 0:38:49.280
<v Speaker 1>when patterns of waves come into contact with one another,

0:38:49.520 --> 0:38:54.200
<v Speaker 1>they create an interference pattern. And this means that waves can,

0:38:54.280 --> 0:38:57.000
<v Speaker 1>for example, sort of cancel each other out. This is

0:38:57.280 --> 0:39:01.080
<v Speaker 1>also known as destructive interference. You might have seen a

0:39:01.120 --> 0:39:03.640
<v Speaker 1>demonstration of this with like speakers. If you take like

0:39:03.719 --> 0:39:07.440
<v Speaker 1>sound speakers and you place them at just the perfect

0:39:07.680 --> 0:39:11.400
<v Speaker 1>distance apart away from you, the sound waves can actually

0:39:11.480 --> 0:39:14.040
<v Speaker 1>cancel each other out, and suddenly you're not hearing the

0:39:14.080 --> 0:39:17.480
<v Speaker 1>sound they're making anymore. But if you turn off one

0:39:17.520 --> 0:39:20.280
<v Speaker 1>of the speakers, then you can hear it again because

0:39:20.320 --> 0:39:24.120
<v Speaker 1>they're not canceling each other out anymore. So that's destructive interference.

0:39:24.120 --> 0:39:27.520
<v Speaker 1>When the peaks and the troughs are um are alternating

0:39:27.719 --> 0:39:30.479
<v Speaker 1>canceling each other out. But peaks and troughs can also

0:39:30.680 --> 0:39:34.080
<v Speaker 1>line up to multiply one another into giant waves, and

0:39:34.120 --> 0:39:39.000
<v Speaker 1>this is known as constructive interference. Ironically, it's the constructive

0:39:39.040 --> 0:39:42.440
<v Speaker 1>interference that is destructive to our stuff, our ships, and

0:39:42.440 --> 0:39:45.560
<v Speaker 1>our structures. Uh. So that's one thing, just the normal

0:39:45.680 --> 0:39:50.200
<v Speaker 1>kinds of wave wave interference patterns. Another thing sounds like

0:39:50.239 --> 0:39:52.920
<v Speaker 1>it taps into the explanation we were just discussing, and

0:39:53.000 --> 0:39:56.840
<v Speaker 1>that's the interaction of water currents with wave patterns created

0:39:56.880 --> 0:40:00.520
<v Speaker 1>by storms. Essentially, when the current is flowing one way

0:40:00.960 --> 0:40:04.919
<v Speaker 1>and storm winds are pushing surface waves the opposite way,

0:40:05.000 --> 0:40:08.840
<v Speaker 1>this can cause an interaction that shortens the frequency of waves,

0:40:09.080 --> 0:40:11.960
<v Speaker 1>and this sometimes leads to waves joining together and forming

0:40:12.000 --> 0:40:16.319
<v Speaker 1>these gigantic rogue waves. But there's one other major proposed

0:40:16.360 --> 0:40:20.319
<v Speaker 1>mechanism or proposed explanation I was reading about two. Uh,

0:40:20.320 --> 0:40:23.880
<v Speaker 1>and this is a hypothesis that deals with nonlinear effects.

0:40:23.920 --> 0:40:26.680
<v Speaker 1>So the details of this are far over my head,

0:40:26.680 --> 0:40:30.080
<v Speaker 1>but I'll do my best. Basically, some research shows that

0:40:30.120 --> 0:40:34.160
<v Speaker 1>you can actually predict the formation of rogue waves if

0:40:34.200 --> 0:40:37.799
<v Speaker 1>you model ocean waves with reference to to a nonlinear

0:40:37.960 --> 0:40:41.200
<v Speaker 1>version of the Shreddinger equation, which of course we normally

0:40:41.200 --> 0:40:43.600
<v Speaker 1>would use to model the behavior of objects at the

0:40:43.640 --> 0:40:47.400
<v Speaker 1>quantum scale, such as individual atoms. But the the interesting

0:40:47.520 --> 0:40:51.080
<v Speaker 1>thing about matter about objects at the quantum scale, like

0:40:51.160 --> 0:40:54.600
<v Speaker 1>atoms or electrons or photons. Is that in many ways

0:40:54.640 --> 0:40:57.520
<v Speaker 1>they seem to behave like waves. You know, that's one

0:40:57.520 --> 0:41:00.279
<v Speaker 1>of the great paradoxes of quantum mechanics, is well, how

0:41:00.280 --> 0:41:04.160
<v Speaker 1>can a particle behave like a wave pattern? But the

0:41:04.239 --> 0:41:07.640
<v Speaker 1>shredding your equation and it's highly predictive. It tells us yes,

0:41:07.680 --> 0:41:10.120
<v Speaker 1>they do in fact behave like a wave pattern, and

0:41:10.160 --> 0:41:12.360
<v Speaker 1>you need to model them like a wave pattern or

0:41:12.400 --> 0:41:15.000
<v Speaker 1>you can't predict what they're gonna do. So the shredding

0:41:15.000 --> 0:41:17.719
<v Speaker 1>your equation is is useful at modeling and predicting these

0:41:18.080 --> 0:41:22.320
<v Speaker 1>behavior of these wave patterns. But but also apparently the

0:41:22.640 --> 0:41:25.560
<v Speaker 1>non linear version of it is relevant to predicting the

0:41:25.600 --> 0:41:28.640
<v Speaker 1>behavior of waves at large scale, like waves in the ocean.

0:41:29.080 --> 0:41:32.160
<v Speaker 1>And the mathematical functions underlying this explanation, Like I said,

0:41:32.160 --> 0:41:34.200
<v Speaker 1>they're way over my head. But essentially it's a model

0:41:34.239 --> 0:41:38.160
<v Speaker 1>that shows how normal interacting wave patterns, just you know,

0:41:38.280 --> 0:41:41.399
<v Speaker 1>standard waves going back and forth in the ocean can

0:41:41.520 --> 0:41:46.319
<v Speaker 1>sometimes become unstable and result in one wave, one wave

0:41:46.440 --> 0:41:51.200
<v Speaker 1>peak leaching or sucking energy from the surrounding wave peaks,

0:41:51.239 --> 0:41:55.239
<v Speaker 1>reducing the surrounding waves, and this one wave becoming huge

0:41:55.320 --> 0:41:58.960
<v Speaker 1>in the process, so that that's another proposed explanation. So

0:41:59.000 --> 0:42:02.240
<v Speaker 1>where are we earlier or in our understanding of rogue waves.

0:42:02.280 --> 0:42:05.319
<v Speaker 1>That's probably the next logical question to get to, because

0:42:05.360 --> 0:42:07.799
<v Speaker 1>if we've discussed already, it's like we we've we we

0:42:07.840 --> 0:42:10.439
<v Speaker 1>haven't known for sure they exist for too terribly long,

0:42:11.080 --> 0:42:15.960
<v Speaker 1>and we're still we're still competing or multiple scenarios that

0:42:16.000 --> 0:42:19.719
<v Speaker 1>may explain how they're occurring. Well, I looked to a

0:42:19.800 --> 0:42:23.680
<v Speaker 1>two thousand nineteen research paper from the University of Southampton

0:42:23.680 --> 0:42:26.200
<v Speaker 1>in the UK, and basically what they did is they

0:42:26.200 --> 0:42:29.040
<v Speaker 1>looked at that they decided to take. Instead of like

0:42:29.080 --> 0:42:32.880
<v Speaker 1>a global look at the data, they tried to isolate it. Uh.

0:42:32.960 --> 0:42:36.839
<v Speaker 1>They looked to fifteen different buoys on the US West

0:42:36.840 --> 0:42:40.280
<v Speaker 1>then cboard, and they looked at a twenty year window,

0:42:40.440 --> 0:42:43.560
<v Speaker 1>So we're looking at ninety four through as being the

0:42:43.640 --> 0:42:46.600
<v Speaker 1>window of data that they were looking at isolated to

0:42:46.680 --> 0:42:51.440
<v Speaker 1>this this region. And uh, this study revealed the following. So,

0:42:51.520 --> 0:42:54.120
<v Speaker 1>first of all, rogue waves vary greatly depending on the

0:42:54.200 --> 0:42:56.960
<v Speaker 1>area of sea and the time period focused on the

0:42:57.040 --> 0:42:59.080
<v Speaker 1>first part of that I think makes sense because we

0:42:59.200 --> 0:43:01.520
<v Speaker 1>discussed it just needs to be twice as big as

0:43:01.600 --> 0:43:04.160
<v Speaker 1>the as the waves in the area. And also this

0:43:04.320 --> 0:43:07.560
<v Speaker 1>is very key. Across to the two decade windows studied,

0:43:07.920 --> 0:43:11.800
<v Speaker 1>instances of rogue waves fell slightly, while the size of

0:43:11.880 --> 0:43:15.920
<v Speaker 1>the individual waves increased. Okay, so there's less of them,

0:43:16.000 --> 0:43:18.279
<v Speaker 1>but they're more powerful when you do get them right.

0:43:18.520 --> 0:43:21.680
<v Speaker 1>Kind of a good news, bad day situation, right. Uh.

0:43:21.760 --> 0:43:23.680
<v Speaker 1>They also found found that you know, rogue waves are

0:43:23.719 --> 0:43:27.320
<v Speaker 1>more prevalent, prevalent and uh and severe in winter months,

0:43:28.000 --> 0:43:33.200
<v Speaker 1>and they're they're happening with increasing frequency within calmer background seas.

0:43:33.400 --> 0:43:37.080
<v Speaker 1>Oh that's interesting. Now we know from previous just first

0:43:37.080 --> 0:43:40.400
<v Speaker 1>of all, from anecdotes, you know, common sailor's knowledge, but

0:43:40.520 --> 0:43:43.080
<v Speaker 1>also I think from more recent research that there are

0:43:43.560 --> 0:43:46.960
<v Speaker 1>rogue wave hot spots in the world where there's particularly

0:43:47.400 --> 0:43:51.480
<v Speaker 1>dangerous sorts of interaction between ocean currents and weather. I know,

0:43:51.600 --> 0:43:53.719
<v Speaker 1>for example, one place that's believed to be a rogue

0:43:53.760 --> 0:43:56.840
<v Speaker 1>wave of hot spot is like the southern Cape of Africa.

0:43:57.239 --> 0:43:59.040
<v Speaker 1>You know, if you're you're going around the Cape of

0:43:59.080 --> 0:44:02.600
<v Speaker 1>Good Hope, it's long been understood as treacherous waters. Yeah,

0:44:03.040 --> 0:44:05.160
<v Speaker 1>but you know, it long believed to be a place

0:44:05.239 --> 0:44:08.040
<v Speaker 1>of bad weather, but also apparently a place of rogue waves,

0:44:08.680 --> 0:44:13.240
<v Speaker 1>So everyone's probably wondering, well, how often are these things occurring? Again,

0:44:13.480 --> 0:44:15.680
<v Speaker 1>there was once this idea that these were once in

0:44:15.719 --> 0:44:18.239
<v Speaker 1>a lifetime events that it was it was like seeing

0:44:18.280 --> 0:44:21.279
<v Speaker 1>a unicorn on the high seas. But it looks like

0:44:21.560 --> 0:44:24.720
<v Speaker 1>now we're talking many times per day in the global

0:44:24.800 --> 0:44:27.520
<v Speaker 1>ocean um and then you know, that's a ship. That's

0:44:27.520 --> 0:44:29.759
<v Speaker 1>a concern for ships at sea, not only you know,

0:44:29.840 --> 0:44:33.000
<v Speaker 1>the global shipping industry, but other vessels as well. H

0:44:33.040 --> 0:44:36.640
<v Speaker 1>A two thousand four study identified more than ten giant

0:44:36.760 --> 0:44:40.480
<v Speaker 1>waves above the twenty five meter or eighty two footmark

0:44:40.920 --> 0:44:46.920
<v Speaker 1>uh during a near three week window. Yeah, it's one

0:44:46.920 --> 0:44:49.120
<v Speaker 1>of those things that makes you thankful that the ocean

0:44:49.280 --> 0:44:51.279
<v Speaker 1>is big and we're not on most of it most

0:44:51.320 --> 0:44:53.359
<v Speaker 1>of the time. But there's a lot of us out

0:44:53.440 --> 0:44:55.040
<v Speaker 1>there and a lot of our stuff out there at

0:44:55.040 --> 0:44:57.839
<v Speaker 1>any given time. Also, again, yeah we're there. There's more

0:44:57.920 --> 0:45:01.040
<v Speaker 1>human activity on the oceans than every or before. Uh.

0:45:01.480 --> 0:45:03.160
<v Speaker 1>Just to give everyone a taste of just that the

0:45:03.200 --> 0:45:06.120
<v Speaker 1>shipping industry alone, because because the shipping industry is huge,

0:45:06.600 --> 0:45:09.080
<v Speaker 1>it's easy to take for granted, but it is how uh,

0:45:09.400 --> 0:45:11.319
<v Speaker 1>most of the goods make their way around the world.

0:45:11.360 --> 0:45:15.520
<v Speaker 1>They're not traveling by airplane, they're traveling via ships. Uh.

0:45:15.640 --> 0:45:17.880
<v Speaker 1>Quin I found some good stats on this from the

0:45:17.920 --> 0:45:21.560
<v Speaker 1>International Chamber of Shipping. So, first of all, the international

0:45:21.600 --> 0:45:24.719
<v Speaker 1>shipping industry is responsible for the carriage of around nine

0:45:25.400 --> 0:45:29.160
<v Speaker 1>of world trade, and a given ship shipping vessel, we're

0:45:29.200 --> 0:45:32.120
<v Speaker 1>talking of a two hundred million dollar investment. Like that's

0:45:32.160 --> 0:45:33.960
<v Speaker 1>the when when you see these ships that are laden

0:45:34.080 --> 0:45:37.239
<v Speaker 1>with shipping containers, Uh, that's a two hundred million dollar vessel.

0:45:37.239 --> 0:45:40.760
<v Speaker 1>You're probably looking at the operation of merchant ships generates

0:45:40.920 --> 0:45:44.239
<v Speaker 1>an estimated annual income of over half a trillion US

0:45:44.320 --> 0:45:48.239
<v Speaker 1>dollars and freight rates. They're over fifty thousand merchant ships

0:45:48.320 --> 0:45:52.040
<v Speaker 1>trading internationally, transporting every kind of cargo. And the world

0:45:52.160 --> 0:45:55.840
<v Speaker 1>fleet and shipping is it's in over a hundred and

0:45:55.880 --> 0:45:59.360
<v Speaker 1>fifty nations and manned by over a million seafares of

0:45:59.440 --> 0:46:04.319
<v Speaker 1>virtually every nationality. So it's it's immense and there's more

0:46:04.360 --> 0:46:06.600
<v Speaker 1>of it than ever before. And then we have these

0:46:06.640 --> 0:46:10.399
<v Speaker 1>waves out there. Yeah, and so the idea that these

0:46:10.719 --> 0:46:14.280
<v Speaker 1>waves could be increasing in intensity or becoming more dangerous,

0:46:15.160 --> 0:46:18.000
<v Speaker 1>that's pretty scary because it doesn't just mean like it's

0:46:18.040 --> 0:46:20.439
<v Speaker 1>scarier for people who physically go out on the water.

0:46:20.520 --> 0:46:23.200
<v Speaker 1>Of course, it certainly is, but it also represents a

0:46:23.360 --> 0:46:27.120
<v Speaker 1>threat to UH, to the world economy, you know, the

0:46:27.200 --> 0:46:31.160
<v Speaker 1>economics of goods moving back and forth. Um. And then

0:46:31.400 --> 0:46:33.960
<v Speaker 1>just some more data from this particular paper, the University

0:46:33.960 --> 0:46:37.520
<v Speaker 1>of Southampton paper UH, just considering the u s West Coast,

0:46:37.600 --> 0:46:39.880
<v Speaker 1>which was the focus of his study. They say that

0:46:40.000 --> 0:46:44.840
<v Speaker 1>here you have of total US containerized trade and that

0:46:45.000 --> 0:46:48.200
<v Speaker 1>this is the largest u AS gateway for container vessels. UH.

0:46:48.280 --> 0:46:50.759
<v Speaker 1>And even when ships are not sunk or capsized by

0:46:51.080 --> 0:46:54.040
<v Speaker 1>a wave like this, there's still the risk of rogue

0:46:54.080 --> 0:46:57.920
<v Speaker 1>wave induced collisions. So you know, that's another thing to consider.

0:46:57.920 --> 0:47:01.200
<v Speaker 1>If you have two boats that are near each other, uh,

0:47:01.520 --> 0:47:03.720
<v Speaker 1>and you have an enormous wave of disrupting the waters,

0:47:03.760 --> 0:47:06.680
<v Speaker 1>then there's a possibility that things could slam together, which

0:47:06.719 --> 0:47:09.400
<v Speaker 1>they're certainly not designed to do. Then, on top of that,

0:47:09.520 --> 0:47:11.439
<v Speaker 1>this is a region where there's just a high volume

0:47:11.480 --> 0:47:17.520
<v Speaker 1>of tanker, bolt carrier, roll on, roll off, passenger fishing ships, um.

0:47:18.000 --> 0:47:20.280
<v Speaker 1>You know, all focused around the ports in the region.

0:47:20.640 --> 0:47:21.840
<v Speaker 1>And then of course you have a fair amount of

0:47:21.880 --> 0:47:25.160
<v Speaker 1>activity just to service offshore structures in the oil and

0:47:25.200 --> 0:47:28.680
<v Speaker 1>gas industry. Coming back to in our examples with oil platforms.

0:47:28.760 --> 0:47:32.000
<v Speaker 1>Earlier rogue waves have also swept people out to sea

0:47:32.080 --> 0:47:36.719
<v Speaker 1>in California and Oregon and uh And then one other point,

0:47:36.800 --> 0:47:41.520
<v Speaker 1>the researchers indicated the global climate change isn't necessarily a

0:47:41.640 --> 0:47:44.440
<v Speaker 1>factor in all of this. Part of this is that

0:47:44.560 --> 0:47:47.719
<v Speaker 1>there's just a great deal of oscillation with with with

0:47:47.840 --> 0:47:50.200
<v Speaker 1>the size of these waves, and we're dealing with such

0:47:50.239 --> 0:47:52.960
<v Speaker 1>a complex system and we have only two decades of

0:47:53.080 --> 0:47:55.840
<v Speaker 1>rogue wave data to deal with here. But at the

0:47:55.880 --> 0:47:58.439
<v Speaker 1>same time, they don't seem to be ruling it out.

0:47:59.040 --> 0:48:02.399
<v Speaker 1>I mean cause of increasing energy, right, if the sea

0:48:02.480 --> 0:48:04.680
<v Speaker 1>levels arising in the oceans are getting warmer and you're

0:48:04.680 --> 0:48:08.279
<v Speaker 1>getting more intense weather patterns. Yeah, So basically they're not

0:48:08.360 --> 0:48:10.920
<v Speaker 1>saying it's not the cause. You're just saying we were

0:48:11.000 --> 0:48:13.960
<v Speaker 1>not presenting that with this data. Ultimately, they again only

0:48:14.080 --> 0:48:16.320
<v Speaker 1>two decades worth of data to go on here. I

0:48:16.520 --> 0:48:19.279
<v Speaker 1>was reading an interview from back in two thousand and

0:48:19.320 --> 0:48:21.879
<v Speaker 1>ten with the author Susan Casey, who wrote a book

0:48:21.880 --> 0:48:24.000
<v Speaker 1>that I read a few years ago and I absolutely loved.

0:48:24.040 --> 0:48:26.319
<v Speaker 1>It's sort of a half memoir, half science book about

0:48:26.320 --> 0:48:29.719
<v Speaker 1>the Fara Lawn Islands off the off sort of around

0:48:29.760 --> 0:48:33.280
<v Speaker 1>where San Francisco is um and and about great white sharks,

0:48:33.320 --> 0:48:35.080
<v Speaker 1>and that that book was called The Devil's Teeth. But

0:48:35.239 --> 0:48:38.160
<v Speaker 1>this interview was about another book she wrote, apparently a

0:48:38.200 --> 0:48:40.920
<v Speaker 1>book about giant waves called The Wave of published in

0:48:41.000 --> 0:48:43.920
<v Speaker 1>two thousand ten, And in the interview she talks about

0:48:43.920 --> 0:48:48.279
<v Speaker 1>how companies that right insurance policies for maritime voyages are

0:48:48.360 --> 0:48:51.280
<v Speaker 1>concerned about increasing risk, and part of this risk seems

0:48:51.320 --> 0:48:55.000
<v Speaker 1>to be concerned about rogue waves. She says, quote Lloyd's

0:48:55.040 --> 0:48:59.000
<v Speaker 1>of London. Of course, you know, big maritime insurer Lloyd's

0:48:59.000 --> 0:49:02.000
<v Speaker 1>of London. Is that really quite concerned about cruise ships?

0:49:02.400 --> 0:49:03.960
<v Speaker 1>One of the guys said to me, this is a

0:49:04.040 --> 0:49:07.000
<v Speaker 1>high concentration of risk. You've got five thousand people on

0:49:07.120 --> 0:49:09.480
<v Speaker 1>boats that are getting bigger and bigger, and they're going

0:49:09.560 --> 0:49:13.319
<v Speaker 1>into gnarly or and gnarly or places. They're all over Antarctica. Now.

0:49:13.440 --> 0:49:16.799
<v Speaker 1>For example, recently one of the hardier cruise ships got

0:49:16.880 --> 0:49:19.360
<v Speaker 1>hit by a hundred foot rogue wave and all of

0:49:19.440 --> 0:49:22.600
<v Speaker 1>its navigation equipment got knocked out and the windows got broken.

0:49:22.960 --> 0:49:25.879
<v Speaker 1>During another recent cruise in Antarctica, all all the people

0:49:26.000 --> 0:49:28.320
<v Speaker 1>ended up in the water, which isn't a good situation.

0:49:28.719 --> 0:49:30.960
<v Speaker 1>By the grace of God, there was another boat nearby.

0:49:31.400 --> 0:49:33.719
<v Speaker 1>Now we're talking about big picture risk here. I just

0:49:33.800 --> 0:49:37.000
<v Speaker 1>want to stress that we're not true more in this episode.

0:49:37.000 --> 0:49:39.080
<v Speaker 1>We're not attempting to scare you out of your next

0:49:39.760 --> 0:49:42.960
<v Speaker 1>oceanic voyage, cruise or anything of that nature. Though I

0:49:43.000 --> 0:49:44.480
<v Speaker 1>think if that were our goal, we could do a

0:49:44.560 --> 0:49:48.360
<v Speaker 1>very good job of it. But well, no, that is

0:49:48.440 --> 0:49:50.719
<v Speaker 1>not our goal. I mean, but yeah, there are obviously

0:49:51.400 --> 0:49:55.920
<v Speaker 1>um going to be huge risks to ocean ocean voyages

0:49:56.000 --> 0:49:58.040
<v Speaker 1>of all kinds, and one of the biggest impacts that

0:49:58.080 --> 0:50:00.600
<v Speaker 1>would be there would obviously be trade. I do think

0:50:00.640 --> 0:50:06.960
<v Speaker 1>it's interesting that there are still, uh such mysterious, unresolved

0:50:07.080 --> 0:50:10.720
<v Speaker 1>questions about the behavior of waves of waves in the ocean.

0:50:10.760 --> 0:50:12.839
<v Speaker 1>I mean, this seems like something that people have been

0:50:12.880 --> 0:50:15.279
<v Speaker 1>aware of for a very long time, been studying for

0:50:15.360 --> 0:50:17.279
<v Speaker 1>a very long time. But it's one of those kind

0:50:17.320 --> 0:50:20.760
<v Speaker 1>of chaotic and complex things that maybe we don't often

0:50:20.840 --> 0:50:24.359
<v Speaker 1>stop to to appreciate the mystery and majesty of what's

0:50:24.360 --> 0:50:27.320
<v Speaker 1>easy to just watch wave activity in the ocean, you know,

0:50:27.400 --> 0:50:29.600
<v Speaker 1>said on the beach or on the deck of a

0:50:29.640 --> 0:50:32.399
<v Speaker 1>ship and watch the waves, and it's calming, and it's

0:50:32.760 --> 0:50:35.080
<v Speaker 1>it's rhythmic. There seems to be a I mean, there

0:50:35.200 --> 0:50:37.080
<v Speaker 1>is an order to it, but it seems to there

0:50:37.080 --> 0:50:39.759
<v Speaker 1>seems to be an order that we can grasp, that

0:50:40.000 --> 0:50:42.920
<v Speaker 1>we can that we can understand from a human perspective.

0:50:43.239 --> 0:50:46.520
<v Speaker 1>And of course, really it's it's ultimately more the domain

0:50:46.800 --> 0:50:52.239
<v Speaker 1>of of increasingly complex um computer simulation programs, if not

0:50:52.560 --> 0:50:56.000
<v Speaker 1>the machinations of some sort of vengeful sea God. Well,

0:50:56.080 --> 0:50:58.000
<v Speaker 1>I think one of the reasons we're so tempted to

0:50:59.120 --> 0:51:01.840
<v Speaker 1>wish to think of the waves as regular as because

0:51:02.160 --> 0:51:04.719
<v Speaker 1>we can listen to them is because it's auditory. Because

0:51:04.760 --> 0:51:08.600
<v Speaker 1>it's auditory information instead of just being visual information. It

0:51:08.680 --> 0:51:11.720
<v Speaker 1>assumes a kind of background rhythm whenever we're by the ocean,

0:51:11.880 --> 0:51:14.080
<v Speaker 1>or we hear something recorded by the ocean, or we're

0:51:14.160 --> 0:51:16.920
<v Speaker 1>on the ocean. Uh, you know, the the wave activity

0:51:17.040 --> 0:51:22.480
<v Speaker 1>becomes the steady, reliable percussion of our lives. And then

0:51:22.560 --> 0:51:25.240
<v Speaker 1>the idea that one of these waves could suddenly reach

0:51:25.320 --> 0:51:27.720
<v Speaker 1>out and be not like the others, be this angry

0:51:27.800 --> 0:51:30.640
<v Speaker 1>hand of God feels like a violation of what nature

0:51:30.680 --> 0:51:33.719
<v Speaker 1>has asked us to expect. Yeah, the white noise app

0:51:33.800 --> 0:51:35.960
<v Speaker 1>that I used to sleep every night. Never gives me

0:51:36.000 --> 0:51:41.080
<v Speaker 1>a rogue way. This is always just consistent calming oceanic activity.

0:51:41.120 --> 0:51:43.120
<v Speaker 1>You know what if it just suddenly screamed your name?

0:51:44.560 --> 0:51:46.359
<v Speaker 1>All right, well there you have it. You know, as

0:51:46.480 --> 0:51:49.359
<v Speaker 1>as we've mentioned before, you know, we were both landsmen here,

0:51:49.920 --> 0:51:51.840
<v Speaker 1>so we would love to hear from the sea folk

0:51:51.920 --> 0:51:54.680
<v Speaker 1>out there. Uh. If you have any anything to add

0:51:54.760 --> 0:51:58.359
<v Speaker 1>on this, have you encountered uh sizeable waves or even

0:51:58.600 --> 0:52:01.759
<v Speaker 1>if you have, you witnessed or seeing the handiwork of

0:52:01.840 --> 0:52:04.400
<v Speaker 1>something that could be classified as a rogue wave, we
