We love seeing @johnnyharris and @cleoabram creating videos together. the both of you are two of my favourite video journalists on the internet! Thank YOU for making the INCREDIBLE videos that y'all do!! ❤❤❤
The best part about the Thorpe maps was that they were the first concrete evidence for plate tectonics and she is often credited in geology with providing the last piece of the puzzle that pushed the theory of plate tectonics from fringe idea to mainstream scientific theory.
40. The state of the lost Is like the depths and layers of darkness In a vast deep ocean, above which are waves crashing upon each other, above which are dark clouds : Depths of darkness, one Above another : if a man Stretches out his hand, He can hardly see it ! For any to whom God Giveth not light, There is no light ! 41. See you not that it is God Whose is Glorified by all creatures in the heavens and on earth, and even the birds (Of the air) with wings Outspread ? Each one knows Its own (mode of) prayer And praise. And God Knows well all that they do. 42. Indeed to God belongs The dominion of the heavens And the earth ; and to God you will all return. 43. See you not that God Makes the clouds move Gently, then joins them Together, then makes them Into a heap ?-then wilt thou See rain issue forth From their midst. And He Sends down from the sky Mountain masses (of clouds) Wherein is hail : He makes it land where He pleases And He turns it away From where He pleases. And the lightening that he produces from it, which blinds the sight. 44. It is God Who alternates The Night and the Day : Verily in all of these things Is a sign for people of understanding ! 45. And God has created Every animal from water : Of them there are some That creep on their bellies ; Some that walk on two legs ; And some that walk on four. God creates what He wills ; For verily God has power Over all things. 46. We have indeed sent down Signs and proofs that make things clear : And God guides whom He wills To a way that is straight. The Noble Qur'an. Chapter of light
Yep she’s a badass, some would say the mother of modern geology - the fact that her research was largely dismissed for decades (yep, good ol boys club in science at play here) is mind blowing.
"We can't be afraid of knowledge for fear of what we'll do with it." Wow! What a statement. I've always loved this. Once, I worked for a group of computer system administrators, some of whom knew much less about the operating system (AT&T UNIX) than we specialists did. For many of them, their attitude was "Don't type that command! You never know what might happen." I couldn't help but laugh because the one who actually said that had no idea of asset permissions. He didn't which level of permissions was dangerous and which was harmless, a perfect example of fear from lack of knowledge. I told my him, "We're safer when we understand why certain things are dangerous." I've always believed that it's smart to learn as much as we can before attempting the unknown so we'll be prepared. If we fail to prepare, we prepare to fail.
But we should absolutely be afraid of this kind of knowledge. Not for fear of what is down there, but fear of what humanity will do to it once it is found. We very rarely have a positive impact on the environment around us. Humans are fleas the earth can't scratch. And now we are about to be the poison in it's drinking water. With luck, an astroid will hit the earth and wipe us out so that the earth can start to heal. That is the best case scenario.
Why "can't" we be afraid? Tesla was. Einstein and Bohr was. Nobel was.. Eventually. I don't know how anyone finds the confidence to call for calm about the application of knowledge when the inventions it leads to are sending the very geniuses who created them into panic mode? My humble philosophy is- When the geniuses are afraid, i am terrified! Especially when no one seems to be listening to them...
I'm an avid scuba diver but no matter how many times I dive I realize I am truly in a different world. There are common things you see as a scuba diver on a reef that most people never get to experience. For example a fish cleaning station with a line of fish waiting their turn to be cleaned by tiny gobies and other types of fish and shrimp. I'm so glad you're doing the series there's so much still to be learned! Thanks Cleo!
Retired ocean lifeguard here, I love the part about the surface giving away the bottom contour. It’s exactly what’s happening in the shoreline. Slightly deeper water breeds rip currents. The water’s shape and color tell a story all day long about the shape of the bathymetry under! A crew that rowed across the pacific from LA to Hilo followed deep trenches leading away from California helped by those currents. It’s amazing.
It doesn't make sense. This topography is supposedly based upon the effects of gravity. A mountain bulge in the earth means more mass in that spot which should create slightly more gravity and pull the water down. Conversely, a trench or valley in the earth would be less mass/gravity in that spot and so should produce a bulge in the water.
@@peterladetto708perhaps I am taking into account how surface currents are effected by wind, weather, rain and waves? and perhaps I have been trained by way too many old men of the sea. 😝 I have known some of the Original Gangsters in Los Angeles with LA County and some legends survive without testing by science. These guys do annual races from King Harbor to Catalina and they can talk a good game but who knows? Maybe they are full of 5hit?! ✌️ If you are curious I’ll try and find that post I referenced but I won’t fight with you. Sounds like you know your stuff. ☺️👍
@@peterladetto708 both occur but at different length and depth scales. The gravity effect is very small, and can only be seen over 100 km's. However the shape of the bottom of the ocean influences the water of the ocean multiple different ways, so when you get closer to the shore, you most certainly can see the effect in small rip tides, but also much larger currents are effected by this. This means if you want to only observe the gravity effect, you have to correct for the currents, and if you want to observe only the currents you have to correct for the gravity. Better ocean observations result in better results in both cases.
@@ciprianpopa1503 are you serious? No really, are you calling bull5hit? It’s cool, ✌️☺️ I am not offended. Trust me I have had people walk up to me and challenge me on that right there in Santa Monica while I was blowing my whistle and moving people out of a pulling rip current. I get it. When time permitted I could hand my polarizing sunglasses to some yuppie and point out the discoloration; I’d win an instant convert. After a big set, water gets “trapped” up on shore and tries to find its way back to sea but keeps getting pushed back up until a patch of sand gives way and that water rushes laterally toward it (feeders) and kicks up more sand as a channel forms, taking the water seaward. The waves don’t break the same over that channel. Both the shape of the wave and the coloration of the water from the sand tell you exactly what’s happening at the bottom. Just like a map. No cap 🧢 the kids say? Further to this point the swell/set waves can be traced to events happening on the other side of the globe. A Newport Beach lifeguard was killed effecting a rescue in large surf that originated from an earthquake in Fukushima, Japan. Lots of great scientists here, ✌️ respect. On this subject I am speaking from field experience not a laboratory. We each have valid perspectives but might use different nomenclature and phraseology to describe the same phenomenon. I am happy to elaborate and reconcile any apparent discrepancies. I offer this perspective lovingly and in good faith! ☺️✌️💜
I live Hilo Hawaii. What you’ve said is true. My house is oceanfront I see the ocean move at all times. The ocean ridge that extends off the island creates a very strange and interesting ocean condition that’s fascinating. We live off of the oceans resources. So knowing how it works is very important to us. Youve done a great job. I love the show.
Great video! Just for a stat, I created the first generally accessible and affordable high-resolution mapping program using the World Database II way back in 1978. It was called AMP - A Mapping Program. And, while the National Center for Atmospheric Research (NCAR) had a program that used the World Database II to create maps, it was very expensive to use. I compressed the entire WDBII onto one Cyber 750 "Disk Pack" at 5 levels of resolution. Using just 5 lines of Fortran code, any student, researcher, scientist could create a map of any part of the world at up to 1 point every 300m resolution WITH their data presented in a variety of methods and usually at a cost of less than $5 (NCAR program to produce the same thing typically cost in the $50s to $100s of dollars in compute time). The program was used at the University of Washington for maybe 5 to 7 years by many departments and hundreds of users. Little did I know that I was at the very beginning of what eventually evolved into Google Maps!
I think you well deserve a UA-cam video on your exploits and your contribution to the lives of others and humanity overall. I don't have the skills myself to help with such an endeavor. I'll go look at your channel and see if perhaps you already have one. Edit: You don't have a video about your project. You do have an amazing water meditation video set in the mountains. Did you record that yourself? If no one has taken the time to document your project for posterity and thus give you the credit you deserve, I do hope you get that some day.
That Marie Tharp map of the ocean floor was straight up incredible. The amount of dedication and skill to finish them is fantastic. I can see how Johnny loved going to the library to look at 'em 😅
🎺☁️ 1 Thessalonians 4 kJV ✝️🩸 14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words. ✝️🩸 Ephesians 1 kJV 7 In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;
When I was a young man, my father (an avid fisherman who died in 1987) always had the latest technology available at the time. A "depth finder" and a "fish finder" and a Loran for navigation. It was primitive by today's standards, and I wish he were around to see how the technology has advanced.
fishfinders are still used heavily by anglers today. In fact, I used it the other day to catch salmon. Depths of up to 260meters can be detected within a certain angle range, and that's off of a 130 dollar version that I cast out into the waters using a fishing rod. It sends the signals back to my phone which is then interpreted on a mobile app, giving me a visual of what's below the water, namely the seabed and fish. Exciting stuff that older folks never got a chance to see. Imagine years from now how far it would continue to advance. It'd be amazing to know exactly what's below the water with the same accuracy and detail as we do land.
on her own? What does that even mean? Every time a woman does something, everyone treats her like a child. "Oh wow, you started this project on your own!! How cute!!!"
@@pyropulseIXXI Hey dude, your bigotry is hanging out, might want to tuck that back in. It's a feat that someone did it on their own, the fact that she is a woman, is something you decided was important to complain about.
@@Ketraarso you choose to defend the side that insinuates that wahmn are incapable and panders to them..... over the side that sees them as equal and wants to only give credit where credit is due? So you support the patriarchy, not having wahmns rights, and treating them like childern/pets?
I am absolutely terrified of the oceans or really any large body of water, even being in a city near one makes me feel uneasy.... The idea of being in the water and having miles of it underneath me is especially terrifying.
I have a friend sorta like that. He truly believes we don’t belong in the ocean and it takes a lot of motivation for him to ever get on a boat I’m the ocean. Lakes are fine for him but the ocean makes him so uneasy and I get it 😂
Thalassophobia is really common for a good reason. The ocean is terrifying and should be respected. Somehow, that fear for me turns into fascination a lot.
Problem is sonar is horrible for sea life, whales in particular. It can destroy their hearing structures, make them echo-location blind and even cause them to beach themselves. I'd like to hear about what they're doing to not maim sea life.
It can be difficult to stop people from finding answers with harmful technology. First they have to learn its harmful and then they have to wait until less or non-harmful means are found. When people really, REALLY want to know, they'll excuse or ignore the harm they cause.
@@ndimageryanddownoutproduct1071active sonar is loud, so submarines almost never use it. Imagine being invisible to a crowd of people, then shouting "HEY! WE'RE OVER HERE!"
Love the video, and your enthusiasm is very catchy, and I particularly liked the the depth graph - it was really... graphic and easy to comprehend, huge cudos for that! Now, I understand that this video wasn't about Marie Tharp, but I still think it would've bared mentioning that she recognized the significance of mapping the ocean floor much earlier than anyone, or at least most of her peers. What makes the story more even more interesting is how her bosses told her not to talk about it for quite a while. Until they realized they were wrong. At least they were man enough to admit they were wrong, but it's still worth mentioning that what she did was even more boss than what you let on here. I think this is a fantastic video, thank you for all your hard work!
Love that Cleo's videos seem to be trending longer. I would absolutely watch a 30-60 min Cleo Abram video from end to end. Or listen to a 1-3 hour podcast, for that matter! 🤠
I couldn't help but notice towards the end of video the slight sound of cotton mouth! I'm honestly no one to judge, so I'm not. Just pointing it out and also hoping maybe she'll see this and take it into consideration lol I'm sure it's not as big of a deal as I'm making it out to be, but it is something that kinda bugs me. Which might just be because I used to smoke weed a lot and therefore cotton mouth was a regular thing for me. So now when I notice it, it triggers me and makes me wish I could smoke again even more so! Haha ok I'm cutting myself off from the internet and I'll see myself out ✌️
Amazing to see how Marie Tharp could make those high quality maps with the limited data she had. I find it really interesting to see how a combination of old and new tech helps us to make an even more accurate map of this mysterious underwater world!
We (the US) actually have extremely good maps of the oceans, we just don't openly publish them for reasons that include national security. The best maps that we do have were not built by public agencies. In the private sector, companies like Exxon have amazing maps of the sea floor in areas that interest them. They do not share these with others.
@@irinalehmann No, because of national security, countries don't share their maps. The detail in off-shore oil mapping is insane but they don't share them because of competition.
@@Rai2M I do not share your fear. Yes, that could be one outcome, but to fixate only on the possible negative outcome and ignore the possible better outcome. It is JUST as likely that we figure AI out in a way that enriches and furthers our species. You are free to your opinion, but doomsaying has never been a good look or a good position on the future. I guess I just have more faith in us than you do. To each their own.
How many species have humans killed off that you can clearly see for a fact? Do you have any idea what percentage is irreparably damaged that you haven't figured out yet??? Humanity kills off everything it can find to get it's hands on with very few exceptions. Hell you men can't even guarantee the women and children they can walk the Earth in peace yet. That would indeed be actual progress. LOL.
I started working at a large private seabed/subsea bed mapping company that did surveys around the world for oil companies at 17 back in 2007 through a friend of my grandma. They wanted a tech legit ‘go for’ and liked my honesty and ability. Anyway, I was immediately trained on how to map seabeds, not hard, and start learning sub seabed imaging, also not hard. The problem with mapping large areas of the seabed is it takes a while for the boats to move out, and the expense. At the company we worked with both a 2d and 3d approach. The singular lines and guessing where and how the undersea ranges are, as shown in the old depth map with Johnny, are the 2d surveys we did. 3d surveys to mor accurately show the sea floor, and what is below, cost more and take way more time for the ships to complete. Disclaimer: I stopped working at that company in December 2015, so my knowledge on the cost of surveys and new tech may be out of date.
I don't think I want us to map the entire planet and know everything about it and to be able to get everywhere, tbh. The bottom of the ocean is the only place available to animals that we haven't completely taken over and destroyed yet. I'm in no hurry for that day to come.
I love your quote at 12:56, "I don't think that we can be afraid of knowledge for fear of what we'll do with it.", and I completely agree! I think we need to be much more afraid of ignorance and what we can do with it!
I was fascinated by your Short on this topic and followed your advice to watch this longer video. I’m so glad I did. I learned so much. Both of you did an excellent job of collaborating on this piece. Excellent journalism.
"This is where the Titan submersible imploded" Checks upload date - 9 months ago WHAT THE FFFFFFFF???? NINE FREAKING MONTHS AGO?? It feels like it happened 3 months ago no joke
Cleo, I'm always so impressed at your videos. Your editors and motion graphics artists need some serious love because the visuals in your videos are always outstanding. Truly one of the best channels out there.
"Saying that we don't want information because we're afraid of what we'll do with it. That's not what helps people." - Incredible quote and perspective! Thank you.
Yes, it's the most humanist quote I've heard in a while. A conservative part of me (probably my parents voice) says "maybe it's naive to think such things" but the curious child in me says "nah, do it"
@@joelmiller3996 lol I just watched that veritasium episode ln about Oppenheimer!! I find it facinating that Oppenheimer was entranced by the thousands year old Bhagavad Gita (where in it somehow accurately describes nuclear weaponry?).. understanding was growing all over the world with the advancement of nuclear science, in nazi Germany mostly... I see your point, along with some other things, like gain of function research, potentially any knowledge can be used nefariously right... and it mostly depends on who's funding the science that determines how it will be used. All medical knowledge could be used by killers, ooh actually a lot of medical knowledge came from nazi killers cringe. Is that reason not to explore the ocean? We can weigh pros and cons, suspect that this knowledge may be used by treasure hunters, maybe people searching for Atlantis, perhaps by militaries that want to plan or counter submarine attacks. But on the other hand, find new species of life, zoology, track tectonic plates and possibly help improve vulcanology(sp?) Geology, meteorology and climatology, pros outweigh cons in my opinion. What do you think?
Well ... Not every information should be public. Should everybody know what poisons pathologists don't test for? We are potentially missing out on so much poetry, beauty and also scientific knowledge by allowing people to keep their diaries secret ... So I don't want anyone to know when there is a big source of coal and diamonds directly under my hometown, because then it won't be a town for long. Also Mrs Abram didn't mention the invasiveness of sonar. It's very, very, very loud. Literally loud enough to kill.
@@joelmiller3996 Its actually a good example, yes we created a tool of mass destruction, but also the means to power whole swats of land with reasonably clean energy. So yes you can always take information and use it for nefarious reasons, but you also can just not do it.
@@joelmiller3996 people really be overestimating the atomic bomb the destruction caused lmao. if anything, it's pure destructive capability has been forcing every country to be peacefully coexisting with each other. It's a good thing that our fear of its power kept us tamed and humble.
@@bigdaddy7729 Regardless of how young or old, never too late to become saved as long as one still draws breath. The Watchman River channel brought me here.
It's a really cool scientific problem actually. I'm doing my PhD about the gravitational mapping method she mentioned, and hope to help provide more accurate global maps in the future! I love maps, and this is the new frontier haha
Hey there! Thanks for what you do! As an ocean lifeguard I had it drilled into me that maps of the ocean are called charts. I am not correcting you! LOL I just find the intersection of these disciplines fascinating and how issues of phraseology are resolved. Do you hear the word “chart” often? Is there by chance a difference? (Charts deal more with the surface maybe?)
If and when you make it in a Scientific Journey for your Contribution to the World and to Science, I hope you remember this post and give us some info on your work. Info of the Journal & Volume would be cool, too. Here's hoping for your future success for Mankind! Keep up the good work!
It's harder to go down there than to go to space. Space is almost a vacuum, so not a lot of "mass" is out there, which means that our satellites and instruments reach further, and the vacuum of space is mor consistent. Water pressure is unforgiving and grows the deeper we go and there is literally water mass in-between the ocean's floor and our sonars/radars etc. so it's like looking through a veil and it is harder to go down there with having your instruments intact. We have so many international, national and even private companies and agencies with enough money to fund these projects but put 2 and 2 together, you realize that deep-sea exploration is unforgivingly hard.
Also, while land is a (more or less) 2d surface, the sea has life in every cubic inch of volume, from the shallowest beach to the deepest depths. There is just so much to explore. In comparison to that, (outer) space is just very very empty in general
Yeah! If they all stop stupidly spending on defence...way many times what they spend on research and technology just to save ourselves from ourselves we would have had precise ocean maps like a half century ago. But being humans insatiable greediness and pettiness is inevitable...
When I go on a cruise I cannot take my eyes off my surroundings. Our oceans are so intriguing even though I can’t see below the surface; it just draws me in. I shoulda been an oceanographer like I wanted to be. TY Cleo!! 🚢
once i saw the movement of whales fleeing from submarines and ships that use intense sonar i can't stop thinking about it, every time i hear stuff like mapping with ultrasound. I've never seen a whale and my country doesn't even border on any ocean but that just stuck with me...
Same thoughts. I can't comment on the main thread but I was wanting to comment how harmful sonar is to marine mammals. Kill some wildlife to get the ocean mapped???
@@myyou7335 It works both ways. A sperm whale's 'clicks' that they use to communicate with other whales, can supposedly reach 230 decibels, which can kill any human divers (or, I suppose anything else) near where it direct the sound. The ocean is a dangerous place. I wonder if the whales know how much their simple communication sounds can damage other living things; whales are supposedly pretty smart.
Imaging sonar does Not harm marine life. You are thinking of active identification sonar used by militaries. Imaging sonar is between 100 and 1800 kilohertz and is Not the same thing. Imaging sonar is completely safe. It’s the same technology used in ultrasound for babies.
The Dutch company named Fugro is market leader when it comes to imaging the ocean depths. They were also hired to find MH370. Dutchies once again on top when it comes to their fight with the water 😌 Fun fact that I heard from a Fugro employee, who gave a guest lecture at university, is that they measure much more than just the ocean depth. These accoustig waves can also propagate through the interior of the ocean surface and see what kind of materials lie below it.
I just found your channel and I must say that you have the most interesting, easily understandable and fun science videos! Your energy lights up the whole video and it just makes it so fun to watch :)
Oh yeah so you really think That the surface of the ocean takes on the shape of the ocean floor. You gotta be something special to think that. water always finds its level!
For anyone that wants to learn more, Laura Trethewey published a book a few months ago called The Deepest Map. Excellent book that covers this topic in more depth.
You have made me adore the ocean, and I thank you for that! This is now one of my favourite topics which I would further like to investigate. Please post more videos regarding this topic! I thank you, and wish you well!
I have a question. Don’t these sonar devices emit such a loud sound that whales can go deaf from it? If so, it would’ve at least been worth being mentioned once while talking about them imo
@@Zerbii most sonar won’t. There is no need for it to be that loud. Whales on the other hand can be heard 400km away by military systems. The military don’t want to be. They put out 180 (blue whale) to 230dB (sperm whale) depending on species - loud enough to injure scuba divers. You will note that the absolute top end of military sonar is almost exactly as loud as a sperm whale. A lot of “research” doesn’t include that background data.
@@Zerbiimilitary grade sonar (for detect submarines at a distance without giving away the source) can research sonar works on much lower amplitudes.
Goodness gracious Cleo, I've recently discovered your channel and have dove head first into the rabbit hole and I gotta say, I really admire your enthusiasm for knowledge and discovery. You bring such a fresh and optimistic persepctive to the world and I think it refelcts the more beautiful side of humanity. You're a true gem with a beautiful mind, so keep shining yor light into our world as you inspire us to do likewise.
Correction: the world's first sonar transducer was the Fessenden Oscillator, developed by Canadian inventor Reginald Fessenden, and first successfully tested in Boston Harbor in 1912. Behm developed his own around the same time and obtained a patent in 1913, but Fessenden got his in the water and working first. Additionally, the sonar systems used by the Allies during the U-Boat Campaign in WWI were based on Fessenden's designs. :)
Regarding sonar, please look into sonars effect on whales, is it a myth that sonar can make them deaf? Cause of stranding whales that they cannot navigate? Maybe a depressing story and not ur cup of tea… your stories are uplifting and interesting, keep up the great work!
Absolutely fantastic video. I was in awe of how little we really know about the oceans but I assumed this meant just the sea life; how ignorant I was about the lack of mapping there was. Cleo, please keep these fascinating videos coming and share more!! X
Cleo, I thoroughly respect your skills and approach. I’m worried however that this video doesn’t answer a question that haunts me about ocean mapping and data production. What if any harm does all of that sonar noise do to the whales and other marine creatures which have incredibly sensitive hearing that serves as a critical part of their sensory life? I have heard that just the military use of booming sonar, which travels great distance underwater can deafen or confuse these beautiful beings. Could you explore this question? Thank you so much.
When I was a kid whenever it was raining and I couldn't play out I'd always end up looking through these two beautiful Atlases my mum had.This video just reminded me of those days.Absolutely gutted they just got lost over time,they were legitimate works of art,I would just sit and be in awe of how much work had gone into them. Sad that they're gone.
This is so interesting. Random question: is the sonar used to map the seabed the same sonar that is killing whales and dolphins via sonic tissue damage? Or is that a different kind of sonar? I'm struggling to find good information about this. Would be great if you could investigate further into this. Thanks
The frequency and power are not high enough on commercial sonars. What you are thinking about are military sonars which need to have the power to go through thermoclines and sediment in the water column so they can ensure that they aren't missing an adversary or a mine below those obstructions. Commercial hydrography ships will just go over the spot again when they have a holiday due to those conditions.
Not really, those are water cannons used to map under the sea floor for oil and gas. Only mapping the sea floor doesn't need that powerful sound. These sonars are probably less powerful than what sperm whale emits.
As far as I know the military sonars are the issue. The mapping ones are just sending signals and catching shapes as it bounces back so is pretty tame and simplistic.
I cannot help but be reminded by this video of another depressing human-caused issue. So you know when you go underwater in the ocean and there is all this sound, well this sound is human caused due to the use of ships, and mainly sonar. It was reported that back before this technology existed, that under the sea was described as a silent tranquil place. That is quite frightening how humans managed to change the entirety of such a massive thing, noticeable from every point in the world.
Did you say there is nowhere you can go in the world where you can't hear man-made sound? I'm trying to understand what that means. If I go to a nearby beach on the Atlantic or the Narragansett Bay and put my head under water, I can't hear those sounds myself. What is the lowest power instrument I can use to hear such noise? (I do know that submarine sonar _can_ be heard with the ear alone for miles.)
Actually the ocean is very noisy from corral reefs, tectonic plates moving, underwater volcanos, whales, fish, seals, etc. Real Science is another great channel and they did a cool video about it
Cleo, your genuine excitement for science and wonder floor me. It's infectious and I love watching your videos. Thank you for being so damn curious and doing the work.

Hey there Cleo! I had a pleasure of seeing a Concorde fly in the early 2000s. My father in law (RIP) was driving myself and my wife to Heathrow airport and I heard this tremendous sound which was clearly coming from an aircraft, but unlike anything I've heard before. The Concorde was on a landing approach. I distinctly remember seeing it parked on the taxiway when we got onto the terminal. Little did we know that we just saw one of the last flights of this magnificent plane. Now, smaller, faster than sound, less fuel intensive aircraft make a lot of sense to me. I'm wondering though whether they can be commercially viable as most of the airlines make money by transporting cargo goods alongside with our luggage. Do you think the industry would be keen to adopt a new aircraft of this design? Keen to know your thoughts. Keep going! Love your enthusiasm!
Starting in the 1950s the Soviet Navy started making hyper accurate maps of the ocean floor. This was the case until the Soviet collapse. This has been known in navel circles since the 50s/60s. You want to know what's going on down there, get some old Soviet sea maps...
Me Cleo is 1 of the rare UA-camrs who seems to genuinely love the topics of the videos, as she seems like a little who has walked into her 1st legit toy store, as she runs around touching each toy saying, "this is my favorite!" Her energy when she narrates, along with the actual knowledge shared keeps me clicking like...the like button!
As a fisherman who has spent many many hours out there in can tell you that you absolutely can see topological changes on the surface in the right situations. IE: theres a “hump” that is like 15ft tall that runs for miles down in the keys. Its about 100-150ft in width. You can literally see the “roadway” on the surface most days, after you develop the skill a bit slightly. Very cool to see your reaction learning this, it definitely blew my mind when i first realized it too
This is so interesting, thank you! I generally very much agree with your optimistic futurism, but I do have a slightly different perspective on the idea that more information is always better. I love science, and so I'm inclined to think the same, that seeking knowledge is good just for it's own sake, but I actually think that's not necessarily true. Taking it to the extreme, researching methods of instantly destroying the entire world when there's absolutely no possible beneficial application of the research, just for the sake of the pursuit of knowledge would not be good, it would be reckless. Knowledge is not good, it's what it allows us to do, which is usually good, but sometimes bad. Back to this example, I agree that it's SO COOL and inspiring that we're able to do something like mapping the entire ocean, a place where humans didn't even evolve to go, I just think that for every potential thing to study we should ask 1. Does it have a high probability of having a large positive impact? 2. Does it have a high probability of having a large negative impact? 3. Are there other ways to achieve the same positive impact without the downsides? and 4. Is this the best use of time and limited resources that could be more effectively applied somewhere else?, and not just assume that it's inherently good because it's knowledge.
You normally make a huge effort to show all sides, but in this, there is no mention of the harm to wild life. Here in Western Australia, Oil and Gas companies are about do this in a Whale area even though the risk to the Whales is very high.
When you mentioned Challenger Deep as the deepest part, I was surprised that no mention of the Marianas Trench was made. You might have said in 1951, the deepest spot in the Marianas Trench was found and named Challenger Deep.
When you really think about it, it's so much more interesting than finding life out in space. I'm so curious to know what lives in the deepest parts of our oceans. Maybe after we map it, it might be easier to find out.
This is so awesome. My last video I watched was of Cleo helping Johnny. NOW I'm watching Johnny helping Cleo! "Mind Blown" 😮 Wait!! Did she just call me a hairless monkey?! 🫣🤣
Wow, your passion really made this video stand out. I've always had thoughts about mapping the oceans and now I feel.....a lot of good things now knowing it's happening!!
Watching this video has reminded me that the MH370 disappearance happened almost a decade ago. As a Malaysian, that brief mention definitely hits hard. Great video by the way, love infographic explanations!
Very cool - the only thing i don‘t agree is : when i have to choose to die 90 sec in the space or less than 1-10 sec in the water i choose the shorter death and Not the lo her one 😂
Love the positivity of this channel. Your videos are very much needed, keep it up. Happy to say I've been here since Johnny first recommended your channel (and I'm picky with what I watch haha)
Just as those maps are a piece of art, so are your videos. You are just so talented and you share all of this with such an amazing passion and with a top level of storytelling that is just impressive. Thank you!
Great video as always. I always appreciate the optimism in these videos in part because it gets people excited for the amazing things that lie ahead of us, which is honestly a sentiment that is much scarcer than our need for it. We need more like this. I do however think that our optimism needs to be paired with care and awareness of the potential impacts of the things we're getting excited about. We do need to understand our planet better and mapping the oceans is one important component of that. Another side of that coin of understanding the planet is a responsibility to the species we share it with. The use of high-powered sound devices in the ocean can be _extremely_ disruptive for oceanic life - whales of course use sound for communicating long-distance (another thing we really should study more closely) and sonar can disrupt their migration, feeding, mating, and other crucial behaviors. We've known for decades now that "mass strandings" of whales are caused by sonar. I wonder if we can minimize the impacts of these sonar mapping activities, or if there are possible alternative methods for exploration and mapping of the oceans. Yes, mapping the ocean is an extremely important part of understanding our world. We also need to be aware of the the effects of the things we do, and that goes for far more than just the effects of sonar: that includes the massive CO2 emissions absorbed by and acidifying the ocean; the immense masses of waste dumped into the oceans; the mass extraction of resources; _et cetera ad nauseum._ We know that those impacts exist, and while they pose a much, much greater threat than things like sonar exploration, it's not like their magnitude justifies a smaller harm. Perhaps an unfortunate metaphor, but a cancer patient can still have their day ruined by a stubbed toe. Our exploration methods should not be that stubbed toe. (And let's not read _too_ deep into it by making a 1:1 comparison of the long-termness or exact proportion of magnitude: the point is big bad doesn't make small bad good). I guess what I'm saying is that I just hope that by the time we get a clear picture of the depths of the ocean, that the picture we get is one that still contains the abundant and beautiful ecosystems we know are down there.
It's so refreshing for someone like me to hear the cultural optimism. Yes, indeed, we need to end the conflicts and look up to the stars and down into the oceans to discover more about our beautiful universe. Stay with it, Cleo. We'll get there. Most of the world is saying it out loud now; some are just not listening, because their identities are entrenched in ideologies that are not, shall we say, generous.
As a person of science it irks me to infinity that people can’t get together and share everything. We can’t get ahead in life if we are fighting each other. We all need to work together to advance civilization to reach a type 1 civilization lol
This is a great video, but I would've loved to hear about how increased sonar mapping of the ocean floor affects ocean life. A lot of marine animals have a super good sense of hearing, and the constant pinging from the mapping can and does affect them negatively. Marine wildlife has been known to avoid natural feeding zones because they can't stand the sound of the sonar.
How gross we’re in a society where we’re afraid to map the ocean floor because we’re afraid of what the rich might do with it. I’d rant but that’s about it summed up. Have a lovely day ❤
11:05 In regards to those two Chinese and Russian sites, those are military harbors. Even the US won’t allow precise mapping of their military harbors. This Brit is clearly a yank sympathizer
My mom was Robert Ballard's (originally found the Titanic) secretary in the 80's and early 90's and I spent a lot of afterschool time hanging out in and around his office at WHOI. This sparked a fascination with unexplored ocean and helped me fathom (pun intended...lol) just how much we don't know about our own planet. It is astounding.
Accurate mapping of the ocean 🌊 will allow us to say that the ocean depths FLEX as more or less water 💦 fills them, thus, sea level rise is much much much much much more complex than anyone has considered.
Pleeeeeease give me more excuses to go look at beautiful maps!! This was so fun thanks for looping me in ✨

Time to find out if reprints of the Marie Tharpe maps are available. Particularly interested in the one shown at 8:44.
Total geek! That’s great!
The best part about the Thorpe maps was that they were the first concrete evidence for plate tectonics and she is often credited in geology with providing the last piece of the puzzle that pushed the theory of plate tectonics from fringe idea to mainstream scientific theory.

And He Sends down from the sky Mountain masses (of clouds) Wherein is hail : He makes it land where He pleases And He turns it away From where He pleases. And the lightening that he produces from it, which blinds the sight.
44. It is God Who alternates The Night and the Day : Verily in all of these things Is a sign for people of understanding !
45. And God has created Every animal from water : Of them there are some That creep on their bellies ; Some that walk on two legs ; And some that walk on four. God creates what He wills ; For verily God has power Over all things.

"We can't be afraid of knowledge for fear of what we'll do with it." Wow! What a statement. I've always loved this. Once, I worked for a group of computer system administrators, some of whom knew much less about the operating system (AT&T UNIX) than we specialists did.
For many of them, their attitude was "Don't type that command! You never know what might happen." I couldn't help but laugh because the one who actually said that had no idea of asset permissions. He didn't which level of permissions was dangerous and which was harmless, a perfect example of fear from lack of knowledge.
I told my him, "We're safer when we understand why certain things are dangerous." I've always believed that it's smart to learn as much as we can before attempting the unknown so we'll be prepared. If we fail to prepare, we prepare to fail.
But we should absolutely be afraid of this kind of knowledge. Not for fear of what is down there, but fear of what humanity will do to it once it is found. We very rarely have a positive impact on the environment around us. Humans are fleas the earth can't scratch. And now we are about to be the poison in it's drinking water. With luck, an astroid will hit the earth and wipe us out so that the earth can start to heal. That is the best case scenario.
Why "can't" we be afraid? Tesla was. Einstein and Bohr was. Nobel was.. Eventually.
I don't know how anyone finds the confidence to call for calm about the application of knowledge when the inventions it leads to are sending the very geniuses who created them into panic mode?
My humble philosophy is- When the geniuses are afraid, i am terrified! Especially when no one seems to be listening to them...
I'm an avid scuba diver but no matter how many times I dive I realize I am truly in a different world. There are common things you see as a scuba diver on a reef that most people never get to experience. For example a fish cleaning station with a line of fish waiting their turn to be cleaned by tiny gobies and other types of fish and shrimp. I'm so glad you're doing the series there's so much still to be learned! Thanks Cleo!

That is adorable and smart and makes me so happy to hear. Thanks for sharing!
And we just go there and eat them, how disturbing
Retired ocean lifeguard here, I love the part about the surface giving away the bottom contour. It’s exactly what’s happening in the shoreline. Slightly deeper water breeds rip currents. The water’s shape and color tell a story all day long about the shape of the bathymetry under!
A crew that rowed across the pacific from LA to Hilo followed deep trenches leading away from California helped by those currents. It’s amazing.
It doesn't make sense.
This topography is supposedly based upon the effects of gravity.
A mountain bulge in the earth means more mass in that spot which should create slightly more gravity and pull the water down. Conversely, a trench or valley in the earth would be less mass/gravity in that spot and so should produce a bulge in the water.
@@peterladetto708perhaps I am taking into account how surface currents are effected by wind, weather, rain and waves? and perhaps I have been trained by way too many old men of the sea. 😝 I have known some of the Original Gangsters in Los Angeles with LA County and some legends survive without testing by science. These guys do annual races from King Harbor to Catalina and they can talk a good game but who knows? Maybe they are full of 5hit?! ✌️
If you are curious I’ll try and find that post I referenced but I won’t fight with you. Sounds like you know your stuff. ☺️👍
@@peterladetto708 both occur but at different length and depth scales. The gravity effect is very small, and can only be seen over 100 km's. However the shape of the bottom of the ocean influences the water of the ocean multiple different ways, so when you get closer to the shore, you most certainly can see the effect in small rip tides, but also much larger currents are effected by this. This means if you want to only observe the gravity effect, you have to correct for the currents, and if you want to observe only the currents you have to correct for the gravity. Better ocean observations result in better results in both cases.
" color tell a story all day long about the shape of the bathymetry under". Sure, tell us more.
@@ciprianpopa1503 are you serious? No really, are you calling bull5hit? It’s cool, ✌️☺️ I am not offended.
Trust me I have had people walk up to me and challenge me on that right there in Santa Monica while I was blowing my whistle and moving people out of a pulling rip current. I get it. When time permitted I could hand my polarizing sunglasses to some yuppie and point out the discoloration; I’d win an instant convert.
After a big set, water gets “trapped” up on shore and tries to find its way back to sea but keeps getting pushed back up until a patch of sand gives way and that water rushes laterally toward it (feeders) and kicks up more sand as a channel forms, taking the water seaward. The waves don’t break the same over that channel. Both the shape of the wave and the coloration of the water from the sand tell you exactly what’s happening at the bottom. Just like a map. No cap 🧢 the kids say?
Further to this point the swell/set waves can be traced to events happening on the other side of the globe. A Newport Beach lifeguard was killed effecting a rescue in large surf that originated from an earthquake in Fukushima, Japan.
Lots of great scientists here, ✌️ respect. On this subject I am speaking from field experience not a laboratory. We each have valid perspectives but might use different nomenclature and phraseology to describe the same phenomenon. I am happy to elaborate and reconcile any apparent discrepancies. I offer this perspective lovingly and in good faith! ☺️✌️💜
I live Hilo Hawaii. What you’ve said is true. My house is oceanfront I see the ocean move at all times. The ocean ridge that extends off the island creates a very strange and interesting ocean condition that’s fascinating. We live off of the oceans resources. So knowing how it works is very important to us. Youve done a great job. I love the show.
Great video! Just for a stat, I created the first generally accessible and affordable high-resolution mapping program using the World Database II way back in 1978. It was called AMP - A Mapping Program. And, while the National Center for Atmospheric Research (NCAR) had a program that used the World Database II to create maps, it was very expensive to use. I compressed the entire WDBII onto one Cyber 750 "Disk Pack" at 5 levels of resolution. Using just 5 lines of Fortran code, any student, researcher, scientist could create a map of any part of the world at up to 1 point every 300m resolution WITH their data presented in a variety of methods and usually at a cost of less than $5 (NCAR program to produce the same thing typically cost in the $50s to $100s of dollars in compute time). The program was used at the University of Washington for maybe 5 to 7 years by many departments and hundreds of users. Little did I know that I was at the very beginning of what eventually evolved into Google Maps!
Wow. That is amazing
That's so cool!
So, the world IS mapped, unlike what this crazy chick says?
that's amazing if that was true, you could make a video explaining it and put some evidence, many ppl would love yo watch
I think you well deserve a UA-cam video on your exploits and your contribution to the lives of others and humanity overall. I don't have the skills myself to help with such an endeavor. I'll go look at your channel and see if perhaps you already have one.

My dad is an oceanographer, and he uses gliders to capture data about the ocean floor, current, temperature etc. Very interesting video!
🎉
When I was a young man, my father (an avid fisherman who died in 1987) always had the latest technology available at the time. A "depth finder" and a "fish finder" and a Loran for navigation. It was primitive by today's standards, and I wish he were around to see how the technology has advanced.
Thanks for sharing this. Makes me think of my grandfather for a similar reason.
...took me to the city. To see a marching band
(Sorry, i had to. search for mcr black parade if you want to know what that means)
fishfinders are still used heavily by anglers today. In fact, I used it the other day to catch salmon. Depths of up to 260meters can be detected within a certain angle range, and that's off of a 130 dollar version that I cast out into the waters using a fishing rod. It sends the signals back to my phone which is then interpreted on a mobile app, giving me a visual of what's below the water, namely the seabed and fish. Exciting stuff that older folks never got a chance to see. Imagine years from now how far it would continue to advance. It'd be amazing to know exactly what's below the water with the same accuracy and detail as we do land.
When I was a young boy, my father took me into the city to see a marching band.

I am absolutely terrified of the oceans or really any large body of water, even being in a city near one makes me feel uneasy.... The idea of being in the water and having miles of it underneath me is especially terrifying.
I have a friend sorta like that. He truly believes we don’t belong in the ocean and it takes a lot of motivation for him to ever get on a boat I’m the ocean. Lakes are fine for him but the ocean makes him so uneasy and I get it 😂
According to some who have sailed it, the ocean is liquid hate.
You are truly a cat person then :D
Thalassophobia is really common for a good reason. The ocean is terrifying and should be respected. Somehow, that fear for me turns into fascination a lot.

Problem is sonar is horrible for sea life, whales in particular. It can destroy their hearing structures, make them echo-location blind and even cause them to beach themselves. I'd like to hear about what they're doing to not maim sea life.
It can be difficult to stop people from finding answers with harmful technology. First they have to learn its harmful and then they have to wait until less or non-harmful means are found. When people really, REALLY want to know, they'll excuse or ignore the harm they cause.
Thankyou for sharing this. I had no idea Sonar does that to them.
How is there any whales then? Pretty much all of them should've been hit by sonar by now
@@DajesOfficialexactly lol. You know how many subs just between Russia and USA?

Love the video, and your enthusiasm is very catchy, and I particularly liked the the depth graph - it was really... graphic and easy to comprehend, huge cudos for that!
Now, I understand that this video wasn't about Marie Tharp, but I still think it would've bared mentioning that she recognized the significance of mapping the ocean floor much earlier than anyone, or at least most of her peers. What makes the story more even more interesting is how her bosses told her not to talk about it for quite a while. Until they realized they were wrong. At least they were man enough to admit they were wrong, but it's still worth mentioning that what she did was even more boss than what you let on here.
I think this is a fantastic video, thank you for all your hard work!
Love that Cleo's videos seem to be trending longer. I would absolutely watch a 30-60 min Cleo Abram video from end to end. Or listen to a 1-3 hour podcast, for that matter! 🤠
@Cleo Abram: Look how many people are interested in longer form content from you! 🤠🙏
I couldn't help but notice towards the end of video the slight sound of cotton mouth! I'm honestly no one to judge, so I'm not. Just pointing it out and also hoping maybe she'll see this and take it into consideration lol I'm sure it's not as big of a deal as I'm making it out to be, but it is something that kinda bugs me. Which might just be because I used to smoke weed a lot and therefore cotton mouth was a regular thing for me. So now when I notice it, it triggers me and makes me wish I could smoke again even more so! Haha ok I'm cutting myself off from the internet and I'll see myself out ✌️
Amazing to see how Marie Tharp could make those high quality maps with the limited data she had. I find it really interesting to see how a combination of old and new tech helps us to make an even more accurate map of this mysterious underwater world!
Maps are becoming all the more critically necessary given the relatively recent collision of the USS Connecticut into an undersea mountain.
We (the US) actually have extremely good maps of the oceans, we just don't openly publish them for reasons that include national security. The best maps that we do have were not built by public agencies. In the private sector, companies like Exxon have amazing maps of the sea floor in areas that interest them. They do not share these with others.
Exactly! Because of national security nobody will let you in their waters to “make a better maps”.
@@irinalehmann No, because of national security, countries don't share their maps. The detail in off-shore oil mapping is insane but they don't share them because of competition.

Some things are best left unknown. Just because we can doesn’t mean we should. Being educated beyond one’s intelligence is real.
Tbh everyone would think like that if the ocean wasn't just space but with insane amounts of pressure
How many species have humans killed off that you can clearly see for a fact? Do you have any idea what percentage is irreparably damaged that you haven't figured out yet??? Humanity kills off everything it can find to get it's hands on with very few exceptions. Hell you men can't even guarantee the women and children they can walk the Earth in peace yet. That would indeed be actual progress. LOL.
I started working at a large private seabed/subsea bed mapping company that did surveys around the world for oil companies at 17 back in 2007 through a friend of my grandma. They wanted a tech legit ‘go for’ and liked my honesty and ability.
Anyway, I was immediately trained on how to map seabeds, not hard, and start learning sub seabed imaging, also not hard.
The problem with mapping large areas of the seabed is it takes a while for the boats to move out, and the expense.
At the company we worked with both a 2d and 3d approach. The singular lines and guessing where and how the undersea ranges are, as shown in the old depth map with Johnny, are the 2d surveys we did. 3d surveys to mor accurately show the sea floor, and what is below, cost more and take way more time for the ships to complete.
Disclaimer:
I stopped working at that company in December 2015, so my knowledge on the cost of surveys and new tech may be out of date.
I don't think I want us to map the entire planet and know everything about it and to be able to get everywhere, tbh. The bottom of the ocean is the only place available to animals that we haven't completely taken over and destroyed yet. I'm in no hurry for that day to come.
I love your quote at 12:56, "I don't think that we can be afraid of knowledge for fear of what we'll do with it.", and I completely agree! I think we need to be much more afraid of ignorance and what we can do with it!

I find it facinating that Oppenheimer was entranced by the thousands year old Bhagavad Gita (where in it somehow accurately describes nuclear weaponry?).. understanding was growing all over the world with the advancement of nuclear science, in nazi Germany mostly... I see your point, along with some other things, like gain of function research, potentially any knowledge can be used nefariously right... and it mostly depends on who's funding the science that determines how it will be used. All medical knowledge could be used by killers, ooh actually a lot of medical knowledge came from nazi killers cringe. Is that reason not to explore the ocean? We can weigh pros and cons, suspect that this knowledge may be used by treasure hunters, maybe people searching for Atlantis, perhaps by militaries that want to plan or counter submarine attacks. But on the other hand, find new species of life, zoology, track tectonic plates and possibly help improve vulcanology(sp?) Geology, meteorology and climatology, pros outweigh cons in my opinion. What do you think?
Well ... Not every information should be public.

Do you hear the word “chart” often? Is there by chance a difference? (Charts deal more with the surface maybe?)
I saw a paper that said they can hear the waves crashing on a shore of the giant oceans of water deep under the earth's crust.
Crazy !
you’re so cool:)
If and when you make it in a Scientific Journey for your Contribution to the World and to Science, I hope you remember this post and give us some info on your work. Info of the Journal & Volume would be cool, too. Here's hoping for your future success for Mankind! Keep up the good work!
Malaysia’s flight being mentioned here makes my heart warmm😭 its is crazy how big the ocean is
It still boggles my mind that only 5% of the earth’s global ocean has been explored so far and the remaining 95% is untouched.
untouched purposefully, but not unpolluted or ravaged
It's harder to go down there than to go to space. Space is almost a vacuum, so not a lot of "mass" is out there, which means that our satellites and instruments reach further, and the vacuum of space is mor consistent.
Water pressure is unforgiving and grows the deeper we go and there is literally water mass in-between the ocean's floor and our sonars/radars etc. so it's like looking through a veil and it is harder to go down there with having your instruments intact.
We have so many international, national and even private companies and agencies with enough money to fund these projects but put 2 and 2 together, you realize that deep-sea exploration is unforgivingly hard.
Also, while land is a (more or less) 2d surface, the sea has life in every cubic inch of volume, from the shallowest beach to the deepest depths. There is just so much to explore. In comparison to that, (outer) space is just very very empty in general
12:16 6% to now at 25%
Yeah! If they all stop stupidly spending on defence...way many times what they spend on research and technology just to save ourselves from ourselves we would have had precise ocean maps like a half century ago.
But being humans insatiable greediness and pettiness is inevitable...
When I go on a cruise I cannot take my eyes off my surroundings. Our oceans are so intriguing even though I can’t see below the surface; it just draws me in. I shoulda been an oceanographer like I wanted to be. TY Cleo!! 🚢
once i saw the movement of whales fleeing from submarines and ships that use intense sonar i can't stop thinking about it, every time i hear stuff like mapping with ultrasound. I've never seen a whale and my country doesn't even border on any ocean but that just stuck with me...
Second that.
Yes! My first thought. It must be awful for pretty much everything that lives there.
Same thoughts. I can't comment on the main thread but I was wanting to comment how harmful sonar is to marine mammals. Kill some wildlife to get the ocean mapped???
@@myyou7335 It works both ways. A sperm whale's 'clicks' that they use to communicate with other whales, can supposedly reach 230 decibels, which can kill any human divers (or, I suppose anything else) near where it direct the sound. The ocean is a dangerous place. I wonder if the whales know how much their simple communication sounds can damage other living things; whales are supposedly pretty smart.
Imaging sonar does Not harm marine life. You are thinking of active identification sonar used by militaries. Imaging sonar is between 100 and 1800 kilohertz and is Not the same thing. Imaging sonar is completely safe. It’s the same technology used in ultrasound for babies.
The Dutch company named Fugro is market leader when it comes to imaging the ocean depths. They were also hired to find MH370. Dutchies once again on top when it comes to their fight with the water 😌
Fun fact that I heard from a Fugro employee, who gave a guest lecture at university, is that they measure much more than just the ocean depth. These accoustig waves can also propagate through the interior of the ocean surface and see what kind of materials lie below it.
I just found your channel and I must say that you have the most interesting, easily understandable and fun science videos! Your energy lights up the whole video and it just makes it so fun to watch :)
Her optimism and attention to detail is huge* I hope her team grow so she can go on a weekly production schedule
it will end with her wanting ai. wont be needed these videos.
@@kaimojepaslt not soon if true
Oh yeah so you really think That the surface of the ocean takes on the shape of the ocean floor. You gotta be something special to think that. water always finds its level!
@@Whatthe243 She is talking about very small deviations.
@@Whatthe243do you think air pressure is constant around the entire world at sea level, or do you believe in weather?
For anyone that wants to learn more, Laura Trethewey published a book a few months ago called The Deepest Map. Excellent book that covers this topic in more depth.
ive read that. its really amazing
0:57 I Don't like being reminded, that theres a place on the earth, where not even the SUN can reach
8:55 "It's considered a work of art- I mean look at it-" Cuts away before spending any significant time to appreciate it
So many videos are edited for people with an attention span of about 2 seconds. It’s very annoying.
From 6 to 25 percent of the ocean floor mapped. Now that's progress.
You have made me adore the ocean, and I thank you for that! This is now one of my favourite topics which I would further like to investigate. Please post more videos regarding this topic! I thank you, and wish you well!
Its so weird how Natalie Portman started a science channel, her only disguise is changing her name and we are all playing along with it
I can't unsee this 😂😂😂
No this chick's way hotter
I see it but it's not that close
Forget what she looks like...my brain has an orgasm watching this channel.🤯
We thought so too...
I have a question. Don’t these sonar devices emit such a loud sound that whales can go deaf from it? If so, it would’ve at least been worth being mentioned once while talking about them imo
Actually no - because whales are really loud too. Some whales can kill fish with sound alone.
Frequencies well outside the hearing range of most sea creatures are used. It’d be like trying to deafen a human with a dog whistle.
Sonar can actually kill them.
@@Zerbii most sonar won’t. There is no need for it to be that loud.
Whales on the other hand can be heard 400km away by military systems. The military don’t want to be. They put out 180 (blue whale) to 230dB (sperm whale) depending on species - loud enough to injure scuba divers. You will note that the absolute top end of military sonar is almost exactly as loud as a sperm whale.
A lot of “research” doesn’t include that background data.
@@Zerbiimilitary grade sonar (for detect submarines at a distance without giving away the source) can research sonar works on much lower amplitudes.
Goodness gracious Cleo, I've recently discovered your channel and have dove head first into the rabbit hole and I gotta say, I really admire your enthusiasm for knowledge and discovery. You bring such a fresh and optimistic persepctive to the world and I think it refelcts the more beautiful side of humanity. You're a true gem with a beautiful mind, so keep shining yor light into our world as you inspire us to do likewise.
Correction: the world's first sonar transducer was the Fessenden Oscillator, developed by Canadian inventor Reginald Fessenden, and first successfully tested in Boston Harbor in 1912. Behm developed his own around the same time and obtained a patent in 1913, but Fessenden got his in the water and working first. Additionally, the sonar systems used by the Allies during the U-Boat Campaign in WWI were based on Fessenden's designs. :)
Regarding sonar, please look into sonars effect on whales, is it a myth that sonar can make them deaf? Cause of stranding whales that they cannot navigate? Maybe a depressing story and not ur cup of tea… your stories are uplifting and interesting, keep up the great work!
Absolutely fantastic video. I was in awe of how little we really know about the oceans but I assumed this meant just the sea life; how ignorant I was about the lack of mapping there was. Cleo, please keep these fascinating videos coming and share more!! X
Cleo, I thoroughly respect your skills and approach. I’m worried however that this video doesn’t answer a question that haunts me about ocean mapping and data production. What if any harm does all of that sonar noise do to the whales and other marine creatures which have incredibly sensitive hearing that serves as a critical part of their sensory life? I have heard that just the military use of booming sonar, which travels great distance underwater can deafen or confuse these beautiful beings. Could you explore this question? Thank you so much.
"I think we can't be afraid of knowledge for fear of what we would do with it."
A quote worthy of remembering.
When I was a kid whenever it was raining and I couldn't play out I'd always end up looking through these two beautiful Atlases my mum had.This video just reminded me of those days.Absolutely gutted they just got lost over time,they were legitimate works of art,I would just sit and be in awe of how much work had gone into them.
Sad that they're gone.
This is so interesting. Random question: is the sonar used to map the seabed the same sonar that is killing whales and dolphins via sonic tissue damage? Or is that a different kind of sonar? I'm struggling to find good information about this. Would be great if you could investigate further into this. Thanks
I want to know this too, mapping the ocean is not worth harming and slaughtering the wildlife that call it home
The frequency and power are not high enough on commercial sonars. What you are thinking about are military sonars which need to have the power to go through thermoclines and sediment in the water column so they can ensure that they aren't missing an adversary or a mine below those obstructions. Commercial hydrography ships will just go over the spot again when they have a holiday due to those conditions.
Not really, those are water cannons used to map under the sea floor for oil and gas. Only mapping the sea floor doesn't need that powerful sound. These sonars are probably less powerful than what sperm whale emits.
As far as I know the military sonars are the issue. The mapping ones are just sending signals and catching shapes as it bounces back so is pretty tame and simplistic.
Sounds a lot like Laura Trethewey's thoroughly researched and recently published book, The Deepest Map.
10:30 the animation is absolutely gorgeous
Love that you're incorporating the title of your account more and more. Super excited about the future of Oceanography as well- great vid as always!
I cannot help but be reminded by this video of another depressing human-caused issue.
So you know when you go underwater in the ocean and there is all this sound, well this sound is human caused due to the use of ships, and mainly sonar.
It was reported that back before this technology existed, that under the sea was described as a silent tranquil place. That is quite frightening how humans managed to change the entirety of such a massive thing, noticeable from every point in the world.
Us humans are more monstrous than any other species out there
Did you say there is nowhere you can go in the world where you can't hear man-made sound? I'm trying to understand what that means. If I go to a nearby beach on the Atlantic or the Narragansett Bay and put my head under water, I can't hear those sounds myself. What is the lowest power instrument I can use to hear such noise? (I do know that submarine sonar _can_ be heard with the ear alone for miles.)
Actually the ocean is very noisy from corral reefs, tectonic plates moving, underwater volcanos, whales, fish, seals, etc. Real Science is another great channel and they did a cool video about it
1:24 good vibe.. I played this 10 times before I continued watching
Cleo, your genuine excitement for science and wonder floor me. It's infectious and I love watching your videos. Thank you for being so damn curious and doing the work.

Hey there Cleo! I had a pleasure of seeing a Concorde fly in the early 2000s. My father in law (RIP) was driving myself and my wife to Heathrow airport and I heard this tremendous sound which was clearly coming from an aircraft, but unlike anything I've heard before. The Concorde was on a landing approach. I distinctly remember seeing it parked on the taxiway when we got onto the terminal. Little did we know that we just saw one of the last flights of this magnificent plane.
Now, smaller, faster than sound, less fuel intensive aircraft make a lot of sense to me. I'm wondering though whether they can be commercially viable as most of the airlines make money by transporting cargo goods alongside with our luggage. Do you think the industry would be keen to adopt a new aircraft of this design? Keen to know your thoughts. Keep going! Love your enthusiasm!
They are studying and designing the shape of the fuselage to reduce the sonic boom of super sonic passenger jets
Starting in the 1950s the Soviet Navy started making hyper accurate maps of the ocean floor. This was the case until the Soviet collapse. This has been known in navel circles since the 50s/60s. You want to know what's going on down there, get some old Soviet sea maps...
Johnny Harris introduced me to this channel so its nice to see they're still collaborating.
Me Cleo is 1 of the rare UA-camrs who seems to genuinely love the topics of the videos, as she seems like a little who has walked into her 1st legit toy store, as she runs around touching each toy saying, "this is my favorite!"
Her energy when she narrates, along with the actual knowledge shared keeps me clicking like...the like button!
The best collab of all time. Both of you put out great reporting with editing to match. Together just takes it to a whole new level.
Imagine what we could accomplish if we all (all countries) worked together as 1 species.
As a fisherman who has spent many many hours out there in can tell you that you absolutely can see topological changes on the surface in the right situations. IE: theres a “hump” that is like 15ft tall that runs for miles down in the keys. Its about 100-150ft in width. You can literally see the “roadway” on the surface most days, after you develop the skill a bit slightly. Very cool to see your reaction learning this, it definitely blew my mind when i first realized it too
This is so interesting, thank you! I generally very much agree with your optimistic futurism, but I do have a slightly different perspective on the idea that more information is always better. I love science, and so I'm inclined to think the same, that seeking knowledge is good just for it's own sake, but I actually think that's not necessarily true. Taking it to the extreme, researching methods of instantly destroying the entire world when there's absolutely no possible beneficial application of the research, just for the sake of the pursuit of knowledge would not be good, it would be reckless. Knowledge is not good, it's what it allows us to do, which is usually good, but sometimes bad. Back to this example, I agree that it's SO COOL and inspiring that we're able to do something like mapping the entire ocean, a place where humans didn't even evolve to go, I just think that for every potential thing to study we should ask 1. Does it have a high probability of having a large positive impact? 2. Does it have a high probability of having a large negative impact? 3. Are there other ways to achieve the same positive impact without the downsides? and 4. Is this the best use of time and limited resources that could be more effectively applied somewhere else?, and not just assume that it's inherently good because it's knowledge.
You normally make a huge effort to show all sides, but in this, there is no mention of the harm to wild life. Here in Western Australia, Oil and Gas companies are about do this in a Whale area even though the risk to the Whales is very high.
She literally just mentioned damage to marene life what are you talking about, watch again
4:09 this is where they start talking about the coolest part of knowledge i NEVER knew and thought was cool!!!
When you mentioned Challenger Deep as the deepest part, I was surprised that no mention of the Marianas Trench was made. You might have said in 1951, the deepest spot in the Marianas Trench was found and named Challenger Deep.
When you really think about it, it's so much more interesting than finding life out in space. I'm so curious to know what lives in the deepest parts of our oceans. Maybe after we map it, it might be easier to find out.
This is so awesome. My last video I watched was of Cleo helping Johnny. NOW I'm watching Johnny helping Cleo! "Mind Blown" 😮
Wait!! Did she just call me a hairless monkey?! 🫣🤣
Recently i know your channel on youtube and i really love your content! So thank you!! You are awesome Cleo
It would be an interesting take to plit up infamous ocean spots first to spot detail.
The first one that comes to my mind is Bermuda Triangle
This is VERY similar to a book I just finished - The Deepest Map by Laura Trethewey.
If this sparked your curiosity the book is a terrific read!
Wow, your passion really made this video stand out. I've always had thoughts about mapping the oceans and now I feel.....a lot of good things now knowing it's happening!!
A lot of mapping has been done here in New Zealand, after finding a large mass of submerged land called zealandia, debated as the 8th continent
all hail kiwiland
Woah, that's so cool!
Watching this video has reminded me that the MH370 disappearance happened almost a decade ago. As a Malaysian, that brief mention definitely hits hard.
Great video by the way, love infographic explanations!
Very cool - the only thing i don‘t agree is : when i have to choose to die 90 sec in the space or less than 1-10 sec in the water i choose the shorter death and Not the lo her one 😂
Love the positivity of this channel. Your videos are very much needed, keep it up. Happy to say I've been here since Johnny first recommended your channel (and I'm picky with what I watch haha)
Just say "I think youre hot". Thats what youre thinking
Just as those maps are a piece of art, so are your videos. You are just so talented and you share all of this with such an amazing passion and with a top level of storytelling that is just impressive. Thank you!
Your enthusiasm for this topic is infectious.
Great video as always. I always appreciate the optimism in these videos in part because it gets people excited for the amazing things that lie ahead of us, which is honestly a sentiment that is much scarcer than our need for it. We need more like this. I do however think that our optimism needs to be paired with care and awareness of the potential impacts of the things we're getting excited about.
We do need to understand our planet better and mapping the oceans is one important component of that. Another side of that coin of understanding the planet is a responsibility to the species we share it with. The use of high-powered sound devices in the ocean can be _extremely_ disruptive for oceanic life - whales of course use sound for communicating long-distance (another thing we really should study more closely) and sonar can disrupt their migration, feeding, mating, and other crucial behaviors. We've known for decades now that "mass strandings" of whales are caused by sonar.
I wonder if we can minimize the impacts of these sonar mapping activities, or if there are possible alternative methods for exploration and mapping of the oceans.
Yes, mapping the ocean is an extremely important part of understanding our world. We also need to be aware of the the effects of the things we do, and that goes for far more than just the effects of sonar: that includes the massive CO2 emissions absorbed by and acidifying the ocean; the immense masses of waste dumped into the oceans; the mass extraction of resources; _et cetera ad nauseum._ We know that those impacts exist, and while they pose a much, much greater threat than things like sonar exploration, it's not like their magnitude justifies a smaller harm. Perhaps an unfortunate metaphor, but a cancer patient can still have their day ruined by a stubbed toe. Our exploration methods should not be that stubbed toe. (And let's not read _too_ deep into it by making a 1:1 comparison of the long-termness or exact proportion of magnitude: the point is big bad doesn't make small bad good).
I guess what I'm saying is that I just hope that by the time we get a clear picture of the depths of the ocean, that the picture we get is one that still contains the abundant and beautiful ecosystems we know are down there.
It's so refreshing for someone like me to hear the cultural optimism. Yes, indeed, we need to end the conflicts and look up to the stars and down into the oceans to discover more about our beautiful universe. Stay with it, Cleo. We'll get there. Most of the world is saying it out loud now; some are just not listening, because their identities are entrenched in ideologies that are not, shall we say, generous.
As a person of science it irks me to infinity that people can’t get together and share everything. We can’t get ahead in life if we are fighting each other. We all need to work together to advance civilization to reach a type 1 civilization lol
This is a great video, but I would've loved to hear about how increased sonar mapping of the ocean floor affects ocean life. A lot of marine animals have a super good sense of hearing, and the constant pinging from the mapping can and does affect them negatively. Marine wildlife has been known to avoid natural feeding zones because they can't stand the sound of the sonar.
Just like honeybees not being able to stand 5G🤔
Her positivity is always inspiring. It makes the direction the world heading towards is much less scarier
She can literally pick the most boring topic or subject to ever exist and I’d still listen to her for days!! ❤❤
How gross we’re in a society where we’re afraid to map the ocean floor because we’re afraid of what the rich might do with it. I’d rant but that’s about it summed up. Have a lovely day ❤
Damn !! your videos are so good and informative. It must take a lot of time to research these topics. Appreciate your hard work
Amazing! It's wonderful to see your genuine and infectious enthusiasm for science!
11:05 In regards to those two Chinese and Russian sites, those are military harbors. Even the US won’t allow precise mapping of their military harbors. This Brit is clearly a yank sympathizer
Thought I saw broly for a sec 00:58😂
My mom was Robert Ballard's (originally found the Titanic) secretary in the 80's and early 90's and I spent a lot of afterschool time hanging out in and around his office at WHOI. This sparked a fascination with unexplored ocean and helped me fathom (pun intended...lol) just how much we don't know about our own planet. It is astounding.
All fun and games till they disturb the kraken 😬
True story.... Colossus
I didn't know Keira Knightley was so interested in the ocean
Accurate mapping of the ocean 🌊 will allow us to say that the ocean depths FLEX as more or less water 💦 fills them, thus, sea level rise is much much much much much more complex than anyone has considered.
No remarks about the potential effects on marine mammals if we significantly increase sonar surveillance?
