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.

"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.

[@brutuschapman2508]

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.

My humble philosophy is- When the geniuses are afraid, i am terrified! Especially when no one seems to be listening to them...

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.

[@justlook.productions]

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.

[@peterladetto708]

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.

[@justlook.productions]

@@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.

[@bjar2417]

@@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.

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.

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!

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.

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.

[@BagerGman]

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.

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.

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...

[@d.e.b.b5788]

@@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.

[@lipinskirl]

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.

[@allangibson8494]

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.

@@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.

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. :)

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.

[@Michellelovestrains]

[@user-rm2qj2jh4l]

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.

I'm struggling to find good information about this. Would be great if you could investigate further into this. Thanks

[@speffish]

I want to know this too, mapping the ocean is not worth harming and slaughtering the wildlife that call it home

[@brettgoldenbloome7036]

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.

[@bltzcstrnx]

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.

[@biazacha]

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.)

[@theprinceofinadequatelighting]

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.

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!
