Indian Ocean - Earth Day Theme

Tanner 0:01

It's almost like Atlantis off of India.

Sups 0:04

Yeah.

Andi 0:06

when you confront how large a tuna is. Yeah. Because it is way bigger than you're thinking. Mm-hmm. however big you think it is, it's bigger.

Tanner 0:16

kind of sounds unbelievable. I've never heard of anything like this.

Andi 0:19

Yeah. And when I was like hearing them again, I'm like, oh, it is just so simple. it's really feels like one of those, like where's the

Tanner 0:27

live?

Andi 0:28

hello and welcome to this episode of the I Should Have Known podcast, the trivia podcast that can't be trusted. Each week, our Quizmaster presents you with four big facts on a topic, but one of those facts is a lie. We are celebrating the earth for the month of April because Earth Day is in this month, So, to kick off our earth themed month, we have Quizmaster soups. Hello. And he's going to be presenting us with four facts on the Indian Ocean. But you need to be careful because one of his facts is a lie. So join me, Andy, and our other host Tanner in figuring out which one it is.

Sups 1:03

Alright. Before we get started, low hanging fruit of the. which is the smallest ocean in the world.

Andi 1:10

Oh, see,

Tanner 1:11

Hmm.

Andi 1:11

There's only one ocean. You guys like it's arbitrary where you break up oceans. Yeah. So like in the US we don't consider like the ocean running Antarctica to be a separate ocean. it all depends on where you're from. Mm-hmm. but I'm guessing Arctic is the answer.

Tanner 1:24

be Arctic Ocean.

Sups 1:25

It indeed is the Arctic Ocean. The largest, of course, is Pacific Pacific

Tanner 1:30

Mm-hmm. Mm-hmm.

Sups 1:31

Indian Ocean, on the other hand, is the third largest.

Andi 1:35

Yes.

Sups 1:35

Alright, let's get going. Fact number one, there's a continent below the Indian Ocean called Maio.

Tanner 1:44

What? Under the water?

Sups 1:46

So deep at the bottom of the Indian Ocean, a research team Found pieces of an ancient continent In 2017, it was called Mauritius because it was found just below the island nation of Mauritius. So the piece of the crust was left over from the breakup of Gana land, which was the super continent that existed more than 200. years ago. Mm-hmm. So initially they thought that this was actually a part of, Mauritius. but when they started analyzing the rocks, they found out that in Mauritius, there is no rock older than 9 million years.

Tanner 2:24

Okay,

Sups 2:24

And they found like this mineral called zicon. Which was about 3 billion years old. So that's how they came to the conclusion that if Mauritius, about 9 million years old. Mm-hmm. So then this mineral, which is way older, so this was part of this continent.

Andi 2:41

Okay. So it's from somewhere else

Tanner 2:42

Like around the time of Goana land, pangia this exactly. Idea. Okay. It's almost like Atlantis off of India.

Sups 2:49

Yeah.

Andi 2:50

So like this comes up a lot where you talk about continental. crust is a specific kind of crust. Right. And not all of it is above sea level. Yeah. Like we know that. So it wouldn't be that surprising if there is like you know, a big chunk of continental crust that is just not above the level now.

Tanner 3:07

Right. There's so much of the sea floor that we never even think about and see.

Andi 3:11

and like the sea levels change and stuff. So like, that's not so bizarre.

Tanner 3:17

That makes, lot of sense. And I mean, I don't know of anything else over there. You know, it's not like no, that can't be. There's something else

Andi 3:23

there. Yeah. Like the mid-Atlantic Ridge, you

Tanner 3:24

you mean? Right,

Andi 3:25

Right. I guess there aren't any hotspots. Like that's kind of weird, you know? Cause that's the only other way you can have an island. like they're part of the continental crust, like New Zealand, or they're formed by hotspots like Hawaii.

Tanner 3:37

Exactly.

Andi 3:38

I don't know. Up to hear

Tanner 3:39

more. Yeah. Yeah.

Sups 3:40

Fact number two. The United Kingdom gave the United States an island for free in the Indian Ocean to set up a military base.

Tanner 3:49

Hmm. This sounds sketchy right off the bat because you said for free.

Andi 3:53

Also, the whole idea about like, Britain is like here half an island that's like thousands and thousands of, miles away from actual

Tanner 4:02

Britain. Right. They're like, this is ours.

Andi 4:04

This sounds very believable.

Sups 4:06

Mm-hmm. let me give you some details then. So in 1965, UK purchased the Chagos archipelago for about 3 million pounds from Mauritius to create what is known today as the. British Indian Ocean Territory. This archipelago included an island called Diego Garcia. these are like bunch of uninhabited islands So the UK gave Diego Garcia to us to set up a military base until 2036. Now, United States did not pay anything to England rather. Gave them a 14 million discount to acquire the Polaris missiles made by Lockheed. These missiles were nuclear armed ballistic missiles

Tanner 4:51

I

Andi 4:52

Everything about this, everything about this is like par for the course for the countries involved.

Tanner 4:58

it's so British, so American

Andi 5:01

So I love that we buy islands with missiles,

Tanner 5:03

Yeah. that's so problematic.

Andi 5:06

Yeah. I do know this from our tropical Islands episode that Mauritius was, uninhabited. There are no indigenous people. Mm-hmm. So like, I believe like these islands, did not have any people on them. Right. then what the Europeans did was then, Especially the British. This is Mauritius. They brought slaves and they're like great free land for slaves And then of course, like. You know, in the 20th century, they're like, you guys get off of these islands. What are you doing here? These are our islands, It's not like we forcibly brought your ancestors here, So, yeah, I mean, a big thumbs up for America and for Britain. Yeah. Um, you know, like it's really feels like one of those, like where's the

Tanner 5:45

live? Yeah. It's, I mean, maybe it fits our ideas. continues the narrative of American militaristic. Do

Andi 5:52

you really think actually America paid millions of dollars to the descendants of these enslaved people and donated money to a UN fund not exist and that no. Like there's no way, like this story is anything other than exactly how soups described it, except maybe worse, honestly.

Sups 6:15

Okay.

Andi 6:15

So cool.

Sups 6:16

All right. Let's do fact number three.

Tanner 6:19

right.

Sups 6:20

Indian Ocean accounts were about 70% of the world's commercially landed tuna.

Tanner 6:27

Tuna.

Andi 6:28

Wow.

Tanner 6:30

I did not know that there was that much fishing done there. I know that it's really important for like shipping. Mm-hmm. right? Because trade. Drews. Yeah. Yeah, totally.

Sups 6:39

So tuna, of course, is one of the most commercially viable fish. Indian Ocean has the largest proportion of tuna market in the. The primary reason for this, because the water temperature in the ocean is between 17 to 30 cent grids, about 61 to 87 Fahrenheit, which apparently is the ideal temperature for tuna. yeah. And so globally, the tuna industry is valued at about 42 billion.

Andi 7:08

Wow.

Sups 7:08

Yeah. fish. Yeah. Indonesia is the top exporter. And Japan the top import.

Andi 7:15

Yeah, I was, just gonna talk about Japan I'm pretty skeptical of this fact because just look at the map, look at the oceans, why wouldn't the biggest ocean be like the biggest proportion? Right? And then if I think about like, what I know about tuna, which this is admittedly not very much, but like Japan is major. consumer of tuna, but also they definitely catch tuna. Mm-hmm. off their own shores. Yeah. Right. Like every morning and then you go to the fish market and it's terrifying when you confront how large a tuna is. Yeah. Because it is way bigger than you're thinking. Mm-hmm. however big you think it is, it's bigger.

Tanner 7:53

Yeah.

Andi 7:53

So that's kind of suspicious. Right. But I mean, it's still of. If it's 70% Indian, that leaves 30%

Sups 8:00

Yeah, So the biggest trade flow happens in the direction of Indonesia to United States, followed by Malta to Japan.

Tanner 8:10

What?

Andi 8:11

Malta. Mm-hmm.

Tanner 8:12

Malta. sends tuna to Japan.

Andi 8:14

tuna. That's weird.

Tanner 8:16

It's interesting that it has to do with the temperature because then it would kind of make sense that the Pacific wouldn't have so much, cuz Japan's pretty far north.

Andi 8:23

Yeah. I mean, the only place that I have seen actual tuna. Cold, they were pretty far north. not the Indian

Sups 8:30

being, Yeah. Yeah. I mean, tunas available in

Andi 8:33

all right. Yeah. Yeah. Tuna is pretty ubiquitous.

Tanner 8:36

But you would set up fishing where they like to live the most. Yeah. So if they like the warm, then I guess Indian would make

Sups 8:43

yeah, Which is why, I mean this is like the biggest export going out of Indonesia.

Andi 8:47

That makes sense. Yeah. Okay. It like makes sense, but it's also very unbelievable. Yeah. When you start throwing numbers in, it seems

Tanner 8:55

suspicious. Yeah. but I don't know anything about the fishing industry in

Andi 8:59

right. Yeah, yeah. Yeah. That's, that's a

Tanner 9:01

in the dark. Yeah. But actually wouldn't peg Indonesia as the biggest fishery in Indian. at all? You know, I think of it more as like the Pacific, but maybe I'm just bad at geography.

Andi 9:13

Yeah. I mean, Indonesia is kind of a weird country cuz it's a bunch of islands. Yeah. it is kind of between oceans because again, there is only one ocean There's no line where it's like, this is no longer the Pacific, this is now the Indian Ocean. Like

Tanner 9:29

this doesn't

Andi 9:30

yeah, I guess it's not so weird to think of Indonesia as Pacific, but it also is definitely Indian. So

Tanner 9:37

Hmm.

Sups 9:37

Okay.

Andi 9:38

All right, one more.

Sups 9:39

Fact number four. the deadliest Tsunami ever recorded in human history. was in 2004 In the Indian Ocean.

Tanner 9:47

Hmm. Okay.

Sups 9:49

according to the Indian Ocean Tsunami Information Center, Managed by unesco. The second deadliest Tsunami in the Indian Ocean was in 1983. it was caused because of an explosion of the krak volcano in Indonesia.

Andi 10:05

right. Cro Towa

Sups 10:07

It triggered waves as high as 37 meters and killed. 37,000 people. Yep. This tsunami actually led to the creation of the volcanic island anatta, which is still active. The deadliest tsunami, which we all know of, is known as the Boxing Day tsunami, which happened in 2004. It was caused because of an earthquake measuring about 9.4 in Richter scale. The epicenter was Bandi as in Indonesia. and. waves could be felt as far as Somalia, which is like 4,500 kilometers away. The earthquake triggered a bunch of tsunamis. 230,000. people died more than million homes and, you know destroyed, I mean, like economies, countries are still recovering from, that.

Tanner 10:59

I've heard that. That one was so bad because of the nature of tsunamis. Right? You can't see them coming. You can't predict them. So even if. recorded the earthquake. You don't know where the tsunami's gonna hit or how strong it's gonna be or when. Mm-hmm. and you can't notify everyone. And then like they can go higher. Yeah. Get to higher land and then just pray that their house doesn't wash

Andi 11:18

walk away.

Tanner 11:18

But,

Andi 11:19

and I think a lot of, especially Western people don't realize how many people live in this region. Oh yeah. Like, It's like the tuna, however many you think it is. It's way more than that. Than that. Like we're talking hundreds of millions of people. Right. and on islands we're like, at a certain point you can't go any higher. Yeah. Like some entire islands were like washed over. So like Yeah. I remember that one. It was

Tanner 11:43

Yeah.

Sups 11:44

And this tsunami is actually, it was one of the first, what is known as a tele tsunami. So because this tsunami led to another tsunami, and that's why it made it so bad, because it was just one after another. Right?

Andi 11:57

yeah, they just kept bouncing off Islands

Tanner 11:59

Yeah. I remember reading about some of the survival tactics for tsunamis when I was doing the other Ocean episodes. Not much you can do. No, that's why the death count is so high, because it's like, well just run away. Just go to higher ground if you can.

Sups 12:12

I mean, and this was like, Badly affected, like India, Indonesia, Australia, remember watching videos where people were in the resorts. Right. Because there's a lot of resorts and like tourism there where people are just laying in the beach and they can see something coming. But by the time they come, even if they go to their hotel room, the whole

Tanner 12:30

Yeah. down. Yeah. Right. So, and it's especially bad because sometimes the water goes out, like it looks like the tide's going out. Yeah. And the ocean's just disappearing. Yeah. Which draws people in. Mm-hmm. and then it comes

Sups 12:42

back and yeah. Yeah.

Tanner 12:44

That's terrible.

Sups 12:45

yeah.

Tanner 12:45

But do you think there were more

Andi 12:47

Yeah, that is interesting

Tanner 12:49

Mm-hmm.

Andi 12:50

I mean, tsunamis aren't super common,

Tanner 12:52

right?

Andi 12:53

Yeah. I really don't know. I, it feels like it would have to be something where it's like, you should have known about this one. So it's like, okay. The one that we were alive for, right? Yes. And then Crocodo, that makes sense. Mm-hmm. Literally like the largest explosion ever on planet earth that we know of. The loudest thing ever. Yeah. Ever recorded. So then it's like, is there something else that we should be thinking of? I don't know.

Tanner 13:17

Right.

Andi 13:17

but then it is a bit, it's a bit weird. I'm a little thrown off by just the very fact of like, well, were there a bunch more before that. Like, I really don't know, so Sure. But it's suspicious because, yeah. Really all you need is one more.

Tanner 13:31

Yeah.

Andi 13:32

and it's like, I should have known about this one more. though.

Tanner 13:35

Hmm.

Andi 13:36

I have no idea So one of those facts was a lie somehow, and we are going to have to figure it out, but we're gonna need soups to please repeat the four of them before we make our guests on which one is a

Sups 13:48

Absolutely. So here are the four facts on Indian Ocean. Fact number one, there's a continent below the Indian Ocean called Mauria. Fact number two, UK gave us an island for free in the Indian Ocean to set up a military base. Fact number three, Indian Ocean accounts for about 70% of the world's commercially landed tuna. And fact number four, the deadliest Tsunami ever recorded was in 2004 in the Indian Ocean.

Andi 14:29

One of those is a lie.

Tanner 14:31

Mm-hmm.

Andi 14:32

Oh boy.

Tanner 14:33

Wow. This is tough. I'm thinking the first one kind of sounds unbelievable. I've never heard of anything like this.

Andi 14:40

Yeah. And when I was like hearing them again, I'm like, oh, it is just so simple. Yeah. So then it's like, well maybe that's. Issue. It's just simply like, no. Yeah. Or it's not called that

Tanner 14:50

Right. whatever. Yeah. I can easily see how that one would be a lie.

Andi 14:54

Yeah. I think I'm looking at the last two maybe. Honestly, I really, really don't know.

Tanner 15:00

Yeah. So you're thinking the

Andi 15:02

this is very hard

Tanner 15:03

Or the tsunamis,

Andi 15:04

maybe the fishing

Tanner 15:05

Mm-hmm.

Andi 15:06

70% seems high. There's a lot of ocean, A lot of fish, right. I'm not an expert on the fishing industry. Right. It's just that like what little context I do have is all other places. Right. Which doesn't necessarily mean that. It's not still true. Yeah. That's very bad reasoning. Right. But that's just all I have to go on. And then the last one seems suspicious for some reason. Mm-hmm. seems like Why this? You know, I don't know.

Tanner 15:34

And if if it's the tuna one, then. does that check out? Is the Indian Ocean the prime, you know, temperature? Is there no better place in the Atlantic Ocean? I don't know. There's a lot of places where that could be a lie.

Andi 15:47

I just think like the Pacific, just simply because it's the biggest, yeah. Biggest ocean. Most fish,

Tanner 15:52

Yeah.

Andi 15:53

you know, like that's a good reason. That's all I got. Like 70 seems really high for the third largest ocean as we talked about at the top of the show. Yeah. So. That seems suspicious, but I really, I don't know. maybe I'll just pick it though.

Tanner 16:07

I'm gonna go with number one cause I've never heard of this

Andi 16:10

interesting.

Tanner 16:11

can see how you can make it a lie.

Andi 16:13

Yeah. Just Atlantis. Yep. fake. Atlantis. You just made up Atlantis. Yeah, I could see that too.

Sups 16:19

All right. Okay. So we've got fact number one and fact number three. So There is indeed an island that was found in 2017 called Mauricia. So yeah, so that fact is true. Yes. Yeah. So fact number three. Absolutely. For the correct reason. It's actually the Pacific Ocean. Indian Ocean is the second, Oh. Um, So the Pacific Ocean is the source of about 70% of commercially landed tuna. The Western and central specific is home to the world's largest tuna fishery, IDing about 57% of the total catch in 2014.

Tanner 16:57

Yeah, Whoa. Yeah.

Sups 16:59

and Indonesia is indeed the biggest exporter, primarily because it's got Pacific Ocean in the

Andi 17:04

the north, Well, yeah. Yeah. So that's kind of what we were saying too, where it's like, well, it's both Indian and Pacific. Yes. So which one is The stats contributing to you that's tricky.

Sups 17:13

Yeah. And this got nothing to do with the temperature. It's actually

Tanner 17:16

actually colder, so oh

Andi 17:18

yeah, I thought,

Sups 17:19

I thought that's, you know, perfect. tempera. It does. tempera. It does. Yeah.

Tanner 17:23

And

Sups 17:23

also there's not much marine life in the Indian ocean. Okay.

Tanner 17:27

Oh

Andi 17:28

Oh, interesting. Huh?

Tanner 17:29

That's why you don't hear so much about Fishing, there. Yeah.

Sups 17:32

Okay.

Tanner 17:32

So I'm not just Crazy.

Sups 17:34

no,

Andi 17:34

no, it's, you're right. the corrections. Yes. I feel much better cuz that was really hard. And then like when your one reasoning is like, okay, well just bigger ocean morph fish. And then you're like, oh, oh that is right. Okay. I really do feel like I should have known that one. That one feels like, yes. Good. But that's really interesting. And those are the cool facts I think of like Indian oceans a bit underappreciated. Yeah. So that's interesting. I should have known

Tanner 18:00

should have known,

Sups 18:01

I should have.

Andi 18:02

Thanks for listening to this episode of the I Should Have Known podcast. We will be celebrating Mother Earth for the rest of the month, and if we could ask one quick thing of you if you can leave us a review wherever you listen to podcasts. it really helps get more exposure for the show and as always,

Tanner 18:21

I should have known. I should have known. I should have known. We all should have known.
