Summary

TLDRThe video script explores the intriguing phenomenon of 'phantom islands'—places that were marked on maps and believed to be real, but never actually existed. It delves into the history of such islands, like Sandy Island, which appeared on maps until 2012 despite being non-existent. The script humorously discusses various reasons for these map errors, including navigational mistakes, optical illusions like Fata Morganas, the influence of myths, and cartographers' laziness. It also highlights how even in the age of satellites, such errors persisted due to outdated map data. The video concludes by acknowledging the challenges faced by historical explorers and the enduring allure of discovery, despite the modern belief that the world has been fully mapped.

Takeaways

  • 🗺️ The concept of 'phantom islands' refers to islands that were marked on maps and believed to be real, but never actually existed.
  • 🌊 One reason for phantom islands was navigational error, where sailors often got lost at sea and thought they found land where there was none.
  • 🌟 Another cause was optical illusions, such as Fata Morganas, which could make distant objects like sea ice appear as islands due to light distortion.
  • 🏞️ Sometimes, real land was mistaken for an island, like the 'Island of California' which was based on a popular novel and later found to be part of the North American mainland.
  • 📚 Historically, mapmakers sometimes copied errors from earlier maps due to laziness or lack of updated information.
  • 🧭 The existence of Sandy Island, a phantom island, was questioned as early as the 1900s but continued to appear on maps until 2012 due to outdated map data used by Google.
  • 🔍 Google Maps' satellite view was not created by stitching together photos but by digitizing old maps, which led to the inclusion of non-existent islands like Sandy Island.
  • 🚢 Explorers like Captain Cook were incentivized to claim new land, which could explain why some phantom islands were added to maps even in doubt.
  • 🤷‍♂️ Despite the advancement of technology, errors like the inclusion of phantom islands in digital maps can still occur, highlighting the human element in map-making.
  • ✅ The removal of phantom islands from maps by the mid-20th century greatly reduced航海上的风险 (navigational risks) for sailors.
  • 🌐 Even with modern technology, there are still parts of the world that remain mysterious, suggesting that the spirit of exploration is still relevant.

Q & A

  • What is the term used to describe an island that is marked on maps but never actually existed?

    -The term used is 'phantom island'.

  • Who discovered the island known as Sandy Island in 1774?

    -Sandy Island was discovered by Captain Cook.

  • Why did the mistake of Sandy Island's existence go uncorrected for so long?

    -The mistake persisted due to a combination of factors including navigational errors, lack of context, and cartographers' laziness or reliance on outdated data.

  • What is a common reason for the existence of phantom islands in historical maps?

    -A common reason is sailors getting lost at sea due to the lack of reliable navigation systems and landmarks.

  • How did the 'Island of California' come to be depicted on early maps?

    -The 'Island of California' was depicted on early maps because early Spanish explorers, influenced by a popular romantic novel, assumed it was an island due to the long stretch of the west coast of North America.

  • What is a Fata Morgana?

    -A Fata Morgana is a special kind of mirage that occurs when a temperature inversion causes a duct to form, which distorts the light's path, making distant objects like sea ice appear as high mountainous land.

  • Why did Google Maps still show Sandy Island as late as 2012?

    -Google Maps showed Sandy Island until 2012 because the pre-2012 edition used map data from the US National Imagery and Mapping Agency, which was based on old maps that predated the French reconnaissance mission that confirmed the non-existence of the island.

  • What was the outcome when an Australian research ship investigated the location of Sandy Island in 2012?

    -The research ship confirmed that there was no land at the location of Sandy Island, thus resolving the discrepancy.

  • Why did the name 'Sandy Island' follow a 'say what you see' naming tradition?

    -The name 'Sandy Island' was chosen by Captain Cook to reflect the sandy nature of the island he believed he had discovered, following a straightforward, descriptive naming convention.

  • What is the significance of the story of Ernest Shackleton and his crew encountering phantom islands?

    -The story of Shackleton and his crew highlights the serious inconvenience that phantom islands could pose to navigators and explorers, emphasizing the importance of accurate cartography for safe sea travel.

  • How has the advent of satellite technology affected the discovery and mapping of new places?

    -Satellite technology has made it possible to map every inch of the Earth's surface with high precision, reducing the likelihood of new discoveries and effectively ending the era of traditional exploration.

🏝️ The Origins of Phantom Islands on Maps

The third paragraph returns to the topic of phantom islands, exploring the reasons behind their appearance on historical maps. It discusses how sailors often got lost at sea due to the lack of reliable navigation systems, leading to false discoveries like Admiral William Cowley's 'Pepys Island.' The paragraph also covers how optical illusions, such as the Fata Morgana mirage, could make sailors believe they saw islands that did not exist, like Captain William Elliot's 'Emerald Island.' Additionally, it touches on how real landmasses were mistaken for islands, such as the 'Island of California,' and how myths and laziness among map makers contributed to the persistence of phantom islands on maps. The speaker concludes with a nod to the past nuisance phantom islands posed to sailors, like Shackleton's crew, and the modern resolution of such cartographic errors.

Keywords

💡Phantom Island

A phantom island is a place that is marked on maps and believed to be real, but which never actually existed. It is a significant concept in the video as it explores the historical instances of such islands and the reasons for their appearance on maps. Sandy Island, for example, was a phantom island that appeared on maps until 2012 despite never existing.

💡Captain Cook

Captain Cook was a British explorer known for his voyages in the Pacific Ocean. In the video, he is mentioned as the discoverer of Sandy Island, which was later found to be a phantom island. His role is crucial as it exemplifies the human element in exploration and the potential for error in historical mapmaking.

💡Sailor Navigation

Sailor navigation refers to the methods and techniques used by sailors to determine their position and direction while at sea. The video discusses how unreliable navigation systems in the past led to the discovery of phantom islands, as sailors often found land where they weren't expecting it, such as in the case of Peppy's Island.

💡Fata Morgana

Fata Morgana is a type of mirage that occurs when light is refracted through layers of air with different temperatures. In the video, it is mentioned as a reason for the discovery of phantom islands, such as Emerald Island, which was 'seen' by Captain William Elliot due to a temperature inversion causing a distortion in the light's path.

💡Map Making

Map making is the process of creating a map, which involves compiling, designing, and executing geographical information. The video highlights map making as a source of phantom islands, as errors or oversights could lead to the inclusion of non-existent islands on maps, such as the Island of California.

💡Digital Maps

Digital maps are map representations in a digital format, often used for navigation and location services. The video discusses the creation of Google's digital maps and how outdated data led to the inclusion of Sandy Island, a phantom island, until it was corrected in 2012.

💡Ground News

Ground News is an app and website mentioned in the video that allows users to compare news articles from different sources. It is used as a promotional example to illustrate the importance of verifying information, which parallels the theme of the video about the verification of geographical discoveries.

💡Exploration

Exploration is the act of traveling through unfamiliar regions to learn about them. The video uses the theme of exploration to discuss the historical context and the evolution of mapmaking, highlighting the contrast between the past, where exploration was a significant endeavor, and the present, where technology has reduced the likelihood of discovering new lands.

💡Satellite Technology

Satellite technology refers to the use of artificial satellites for various purposes, including mapping. The video discusses how satellite technology has contributed to the accurate mapping of the Earth's surface, effectively ending the era of discovering phantom islands through traditional exploration.

💡French New Caledonia

French New Caledonia is a territory of France in the southwest Pacific Ocean. In the video, it is mentioned in the context of Sandy Island, which was believed to be in the region of French New Caledonia. The French had a role in the discovery that Sandy Island did not exist, which is tied to the video's theme of correcting historical map errors.

💡US National Imagery and Mapping Agency (NIMA)

The US National Imagery and Mapping Agency, known as NIMA, was a U.S. government agency responsible for providing and maintaining geospatial intelligence data. The video references NIMA's data, which was used in pre-2012 Google Maps and included outdated information about Sandy Island, illustrating the reliance on historical map data in digital mapping.

Highlights

The episode discusses the concept of 'phantom islands' - islands that appear on maps but do not actually exist.

Sandy Island, discovered by Captain Cook in 1774, is a famous example of a phantom island that appeared on maps until 2012.

Phantom islands can be caused by navigational errors, such as when sailors get lost at sea due to the lack of reliable systems.

Admiral William Cowley's discovery of 'Pepys Island' in 1683 was later found to be a case of mistaken identity with the Falkland Islands.

Optical illusions like the Fata Morgana mirage can cause sailors to see islands that aren't there, as experienced by Captain William Elliot with 'Emerald Island'.

The 'Island of California' was a cartographic error that persisted due to its popularity in literature and desire for it to exist.

Map makers sometimes included mythical places like 'Braasil' from Irish folklore on maps due to laziness or lack of fact-checking.

Phantom islands were not just cartographic errors but could pose serious challenges to sailors who relied on maps for navigation.

Ernest Shackleton's crew faced a series of phantom islands during their 1909 journey, highlighting the practical impact of these map errors.

Sandy Island's continued appearance on Google Maps until 2012 was due to outdated map data that predated the French discovery that it did not exist.

Digital satellite maps, like Google's, can still contain errors due to the process of digitizing old maps without up-to-date verification.

An Australian research ship finally confirmed the non-existence of Sandy Island in 2012, correcting the long-standing map error.

The episode humorously suggests that despite the advancement in mapping technology, there's still room for modern exploration.

The incentives for explorers to claim new land discoveries, even in doubt, is highlighted as a contributing factor to phantom islands.

The world map is portrayed as complete and perfect in 2024, with a satirical take on the idea that no more discoveries or errors will occur.

Ground News is introduced as an app and website that helps users compare news articles and understand different perspectives.

00:03

welcome to...

Map Men...

00:07

I'm the men... and here's the map.

♫ Map Man, Map Man

♫ Map Map Map Man Man

00:17

Many years ago, being an explorer  was the best job in the world.

00:20

The perks were obvious

00:21

months at sea, far from loved ones

00:23

with a good chance you might starve to death.

00:25

But these days there's no  such thing as an explorer.

00:28

And what do you want to be when you grow up?

00:29

An explorer.

00:30

Well you can't cos of Google Earth.

00:32

Satellite technology was the death of discovery

00:34

as new aerial images could be used to perfectly map every inch of ter...

00:38

Hang on, what was that?

00:39

What was what?

00:39

Go back a bit.

00:40

But it's just ocean.

00:41

There, that black smudge.

00:43

Huh... something in the sea has been censored.

00:45

Oh my mistake, this is the pre-2012 Google Map.

00:47

In the up-to-date one, it's just empty ocean.

00:50

Wait, that's an even bigger mystery!

00:52

It's time to do some research.

00:55

I've just read a Wikipedia summary of this incredibly boring book

00:59

and it turns out this is the location of an island discovered by Captain Cook in 1774.

01:04

Cook was sailing in the South Pacific doing what he did best -

01:07

Looking out for land either small enough to be a crash hazard

01:09

or big enough to colonise.

01:11

And he succeeded, successfully spotting a small and previously unknown sandy island.

01:15

In a say what you see naming tradition befitting a man associated with Australia

01:19

he named it...

01:20

Sandy Island.

01:22

Sandy Island went on to appear on lots of maps, right up until 2012.

01:26

But it oughtn't have. Because it turns out

01:28

Sandy island has never, and never has, existed.

01:31

Sandy island is what's known as a "phantom Island"

01:34

an island that's marked on  maps and believed to be real

01:37

but which was never actually there.

01:39

So if there was nothing there why did Captain Cook think there was?

01:42

And why did it stay on maps for so long?

01:44

And how did this mistake go uncorrected for so many hundreds of years

01:47

right into the age of satellites?

01:49

The best way to answer that  is by looking at lots of 

01:51

famous examples of phantom  islands throughout history

01:54

each with their own explanations.

01:55

And thankfully I've made a list.

01:57

So have I. I'll start.

01:59

Reason number one: Sailors often got lost.

02:03

The sea is big

02:04

with very few landmarks.

02:06

So, back when they didn't have  reliable navigation systems

02:08

or fancy boats

02:10

or fresh fruit

02:11

you can understand how, on a cloudy and very stormy night

02:16

it wasn't easy to find your way to Kenya.

02:19

Because it was so hard to know exactly where you were

02:21

sailors often found land where they weren't expecting it.

02:24

A great example of this is Peppy's Island

02:26

"Peeps" Island.

02:27

If it doesn't exist, I can  pronounce it how I want.

02:29

In 1683 Admiral William Cowley, on a ship called The Bachelor's Delight

02:33

was just off the coast of South America

02:35

when he, inverted commas, "discovered" inverted commas, so-called "Pepys Island"

02:40

Cowley was delighted with the find and wrote at length about his great discovery.

02:44

"The island has a pleasant aspect.

02:46

There were a large number of birds.

02:47

We killed as many as we needed for food.

02:50

They were quite tasty."

02:51

Pepys Island appeared on 110 maps over the following century

02:55

despite no one but Cowley ever catching a glimpse of it.

02:57

Many sailors tried to find Pepys Island including Captain Cook

03:00

But no one ever managed it.

03:02

In the 19th century, historians looked at Cowley's extensive descriptions and sketches of Pepys Island

03:07

and noticed that they had  a striking similarity with

03:09

The Falklands, 280 miles further south.

03:12

Cowley had been in the Falkland Islands all along

03:14

and Pepys was finally pooped.

03:17

Reason number two...

03:18

Uh uh, my turn.

03:19

Reason number two - a trick of the light.

03:22

Not all phantom islands are a  result of navigational error.

03:25

Even when sailors knew exactly where they were

03:27

they might not have known exactly what they were looking at.

03:30

In 1821, Captain William  Elliot spotted an island with 

03:33

high mountainous land between  Australia and South America.

03:36

He named it...

03:37

"Emerald island."

03:38

So if there was nothing there, then what not on Earth was he looking at?

03:42

Because he was in such a cold part of the world, 

03:44

Elliot had likely fallen victim  to a special kind of mirage.

03:47

Normally, things like this pack of sea ice which are straight ahead

03:50

appear to be straight ahead.

03:52

But, when a temperature inversion occurs

03:54

with cold air on top of hot air

03:56

a duct can form which distorts the light's path,

03:59

meaning this pack of sea ice now appears to be high in mountainous land

04:02

which is precisely what Elliot said he saw.

04:05

These mirages are known as Fata Morganas.

04:07

And as these terrifying pictures  of floating boats prove, 

04:10

could be very convincing.

04:11

Non-existent Emerald Island featured boldly on maps for almost 100 years

04:15

partly because nobody could be bothered to sail all the way back here just to check.

04:19

Reason number three:

04:20

The thing discovered is real, is really there and is land, but isn't an island.

04:25

One example of...

04:26

Oh, we have to take this. Sorry.

04:32

This just in... a local boy has reportedly taken home a rare Golden Goose

04:36

after climbing a beanstalk and overcoming an evil man-eating giant.

04:41

Breaking news... an unsuspecting Goose farmer has had his golden egg laying bird stolen

04:45

by a tiny man accused of breaking and entering

04:48

She hadn't expected to see him come home with the biggest jackpot in make-believe history.

04:53

...putting hard-working giants out of business

04:55

...clear sign of magic as a force for good

04:58

...witchcraft being used by criminals.

05:01

Do you ever get the feeling it's hard to know whom to trust when you're consuming news?

05:05

Yes. And that's why more and more  people are using Ground News.

06:05

Thank you. Well, that's all from us this lunchtime

06:07

Thanks again to our sponsor Ground News

06:08

And now it's time for the news in your area.

06:16

Right... where were we?

06:17

Ah yes. Things that weren't islands...

06:19

The name "California" historically  refers to a long stretch 

06:21

of the west coast of North America

06:23

only the top half of which  ended up as part of the USA.

06:26

The bottom half, or "Baja California" is this long peninsula dangling off Mexico

06:30

When the early Spanish explorers landed here in the 1600s

06:33

the extraordinary longness of what we now know is the Gulf of California...

06:36

(¡Ah, is boring!)

06:37

...meant that they never  made it all the way up to the 

06:39

connecty bit up the top

06:40

and made the understandable assumption that California was an island.

06:44

The "Island of California" appeared on many of the first maps of the newly discovered continent

06:48

and this now famous map mistake went on to appear on thousands of maps

06:52

right up until the end of the 18th century.

06:54

Did it really take them that long to figure out it wasn't an island?

06:57

No. The island had been disproven several times by several explorers

07:00

but the mistake persisted  on maps for so many years 

07:03

because people wanted it to exist.

07:05

The explorers named the  fictional "Island of California" 

07:07

after the even more fictional  "Island of California"

07:10

from a popular 16th century romantic novel

07:12

about an island populated entirely by Amazonian women.

07:15

In an era where European  high society were using maps 

07:18

for decoration rather than navigation

07:20

it made artistic if not  geographic sense to include 

07:23

the famous island that  well-read people wanted to see.

07:26

Ancient myths have been the source of a 

07:27

surprisingly large number  of multiplied map mistruths

07:30

which brings us to the fourth  reason for phantom islands...

07:33

Map makers are lazy.

07:35

Our favourite completely  fictional island that clumsily 

07:38

sleepwalked its way onto factual maps

07:40

is this mythical one supposedly  found in the Atlantic 

07:42

off the west coast of Ireland, called Brasil.

07:45

What?

07:45

Not to be confused with  Brazil, which is also found 

07:47

in the Atlantic off the west coast of Ireland.

07:49

The two are in no way related, and the sameness of their names is a complete coincidence.

07:52

"Brazzle", as it's probably pronounced, is an enchanted island from Irish folklore

07:56

which, as legend has it, is forever cloaked in mist

07:59

but can be seen for just one day every seven years

08:01

like that ITV documentary about those children who turned into adults.

08:04

It first turned up on this portolan chart of 1325

08:07

when inaccuracies were a reasonably expected hazard of cartography

08:10

and distinguishing myth from reality was a low priority.

08:13

Once Brasil...

08:14

(not that one)

08:14

...made the jump from fairy tale to map,

08:16

it was only a matter of time before another map maker got the wrong end of the stick

08:20

and stuck it on their map because they were too lazy to do their own research.

08:23

And that's exactly what happened in 1375, when Brasil...

08:26

(not that one)

08:27

...turned up on the Catalan Atlas.

08:28

And now that it was on two maps, that was as good as a fact for all future cartographers

08:32

and it only snowballed from there.

08:34

Getting lost, trick of the light, lack of context and laziness are just...

08:38

four ways that Islands can be wrongly discovered.

08:41

It goes without saying that there are dozens more

08:43

including icebergs, pumice rafts, dense fog and dehydrated hallucinations.

08:47

So it's no wonder that through dozens of mistakes on hundreds of maps,

08:50

the world was littered with phantom islands.

08:53

These days phantom islands are merely amusing map anomalies

08:56

but not so long ago, for some sailors, phantom islands were a very serious nuisance.

09:00

In 1909, Ernest Shackleton and his crew were on board the HMS Nimrod

09:04

making their way home after a failed attempt to reach the South Pole.

09:07

(Boo!) (Sorry, lads.)

09:09

Looking at his map, Shackleton planned some much needed rest stops

09:12

between Sydney and South America.

09:14

Unfortunately the first of these was Royal Island.

09:17

Which turned out to be a phantom island.

09:19

Luckily they had Emerald Island to look forward to next.

09:22

But, as discussed 5 minutes and 49 seconds ago,

09:25

Emerald Island turned out to be another phantom island.

09:28

Undaunted, the exhausted crew continued on to Nimrod Island.

09:31

Which turned out to be another phantom island.

09:33

Leaving only Dougherty Island remaining, which...

09:36

Turned out to be another phantom island,

09:38

making this the greatest voyage of un-discovery in the history of exploration.

09:42

(...Yaay?)

09:44

Thankfully, for anyone trying to sail from Sydney to South America nowadays,

09:47

almost every phantom island ended up being undiscovered by the mid 20th century.

09:51

But how did Sandy Island manage to keep appearing on Google Maps as late as 2012?

09:57

Oh yeah, I was going to tell you, sorry. Erm...

09:58

It was down to the French.

10:01

Sandy Island, if it did exist, would belong to

10:03

and be the mapping responsibility of France

10:05

as it's in the region of French New Caledonia.

10:07

Its existence had been in  doubt since the early 1900s.

10:11

So in 1974, a French flying reconnaissance mission went to check their island out

10:15

and to their not surprise, certified that there was nothing there.

10:19

Which incidentally is the  second time we've discussed 

10:21

France getting smaller as a  result of a proper survey.

10:23

Having un-discovered their own territory,

10:25

the French pulled out all  the stops to tell everybody 

10:27

that there was less France in the world.

10:30

Fast forward to the 21st century

10:32

when Google created their digital maps with satellite view.

10:35

Satellite view is not  created, as you might expect,

10:37

by taking lots of photos, stitching them together

10:40

and adding the map detail on top.

10:41

It's far quicker, easier, and more accurate to do it the other way around.

10:45

The pre-2012 edition used map data from the US National Imagery and Mapping Agency.

10:50

Data which had been digitised based on old maps that predated the French undiscovery.

10:55

So the satellites found sea

10:56

but their maps showed that there should be land.

10:58

And that's why they add a big black smudge...

11:01

meaning "error".

11:02

Because most people use satellite view just to look at their own house

11:05

and this was a part of the world where the fish don't even have dial-up

11:07

this smudge went largely unnoticed.

11:09

Until 2012 when a curious Australian research ship decided to take a detour

11:13

to check out the discrepancy once and for all.

11:15

And when they got there on the 26th of November

11:18

they announced to the world...

11:19

"Nope, nope, nope, nope, nope, nope, nope, nope, nope, nope."

11:22

So even in the world of digital satellite maps

11:25

there are still parts of the world that remain mysterious

11:27

and I could still grow up to be an explorer?

11:29

No cos you haven't got a boat.

11:30

Oh.

11:31

It's all too easy to mock explorers who made silly mistakes

11:34

but before we let you go, consider this.

11:36

Discovering land was their job.

11:38

They were paid to do it, and paid more the more they did it.

11:40

So, even if Cook was in doubt about what he saw...

11:43

Hmm, could be driftwood...

11:44

He was incentivised to claim it was land for king and country.

11:47

Have you seen something Sir?

11:49

Er... er... yes.

11:51

land...

11:52

mark that down as land.

11:56

Today in 2024, the world map is completely perfect

12:00

and we're certain that nothing will be discovered or undiscovered

12:02

ever again ever ever.
