I always thought the seas were blue due to reflection from the sky. It was really interesting to hear about the colour absorption. The Presenter is very good. She is enthusiastic about the subject and her voice is easy to listen to, clear and informative imho.
Given that the ocean is a completely different shade of blue (more like cobalt rather than sky blue), it should be pretty obvious that it's not just reflecting the sky. Not to mention that whenever you see pictures/footage from divers inside the ocean, it's still blue. If it were a reflection, it'd be a) the same color as the sky and b) only blue when viewed from above the surface.
bro, exactly... but she said only the large storage of water can absorb the red light and reflect blue. but the pools are not as big as the rivers are. then how isthat the rivers doesn't seems to be blue and the pools do?
Always assumed it was straight up because the sky was blue. Awesome vid. Recently launched my channel in English, after running a Turkish channel for almost a year. After a year on the Turkish platform, glad to be on the same page with some channels like this one. Also never saw this host, but she is awesome! Keep doing your thang!
And if you're interested in water and blue... Heavy water (the kind from reactors that has deuterium/tritium instead of original Hydrogen isotope) is actually not blue... It's just... grey as it gets deeper because the molecules don't wiggle to reflect the blue either... they just sort of absorb all the light... :o)
Clone, please refrain from making anymore patronizing statements. Not for the sake of others, I assure you, you're simply embarassing yourself. If we were to go by your analogy, then the original post would have instead had the statement "I assumed the ocean was blue because the ocean was blue". The sky and the ocean are two separate entities - candy is one. Again, I reiterate, please refrain from embarrassing yourself any further. For your own sake, and for the sake of our remaining brain cells.
It was my first SciShow video and thanks to the host for her voice and her way of presenting information. It`s hard for me to be interested in something but you made it. Also thanks to the team of creators for the work done on the video and its content. You did and continue doing good science videos, which educate people all over the world. Even from Ukraine. P.S. Sorry if my English wasn`t good enough. I can understand it, but using it for conversation still hard enough.
Thoughts from an oceanographer- ever thought about a Crash Course: Oceanography? The oceans play such a pivotal role in global element cycling, heat distribution, climate change, and basically life as we know it, yet it's a topic people know almost nothing about!
And here in England, the sea looks a dull grey. Maybe it's the silt and clay (which is the most likely option), or perhaps it's to reflect the miserable grey sky that likes to "brighten" each day with rain, rain and even more rain. But hey, at least it gives us brits something to complain about, not that we wouldn't be complaining anyhow. That's the stereotype anyway.
+LegoLassy Down where I am I've been told it's chalk in the water but thematically I prefer the idea that it reflects our collective outlook on everything :)
Americans: "Tomorrow WILL be a better day, because we're America and we're the BEST" Brits: "Well, it seems to be another miserable day down here in the UK. How can I tell? It's bl**dy raining again and it's too bl**dy cold and-- etc, etc."
You know what's also cool? If the oceans were made of heavy water, they'd be pretty much clear. Heavy water is clear but normal water is a very pale blue. Shallow bodies of water would just have the color of whatever's on the bottom or in the water column. Extremely deep water would appear dark gray, by absorbing/scattering light of all visible wavelengths virtually equally, minus the little bit that gets reflected back. Why? Molecules absorb light at whatever frequencies make their bonds resonate and vibrate, like masses on a spring. These vibrational modes mostly absorb at infrared wavelengths, but there are weaker secondary harmonic vibrations at higher energies (lower wavelengths) too, causing a bunch of weaker secondary absorption bands at lower wavelengths. For light water, some of these harmonics go out into the visible range, with some weak absorption bands at 660 nm (red) and 740 nm (deep red, almost IR). So a little bit of water is clear, but the red light gets filtered out enough that a few meters of pure water is noticeably blue. But when you put in deuterium in place of regular hydrogen, the masses on the H ends of the O-H bonds are double the normal mass. This shifts the absorption spectrum of the bond towards the IR, so that the bands corresponding to the weak red absorption of water get moved out into the near infrared region (800-1000 nm, IIRC), and there's practically no absorbance anywhere in the 390-750 nm visible range.
You're reading my mind. Went whale watching with visiting family today and wondered this. Had done the same with previous visitors, but the water had been more gray the other times. This time, it was a bright, medium blue.
I have observed this phenomenon in a swimming pool being filled with water. The pool's floor and walls were all white tiles. At first the water was clear up to 2-3 feet. As it approached the 5 feet mark it suddenly gave off a 'bluer' shade despite the pool having all white tiles. Could it be that the absorption and reflection rate is tied to the volume and/or density of the water? Like the clear glass of water in the video, despite it being able to absorb some blue light, it clearly isn't color blue.
Lets just not talk about the video and instead rip into the host who is doing an awesome job. That's how this works right? But seriously, can we not just appreciate the fantastic, high quality content that they bring us for free?
You people are making things up and judging her for it. Your own perception is feeding into itself and creating this biased, twisted version of what is actual reality.
Personally, I'm more interested in the content and not so much the host. So Olivia doesn't bother me, and I don't really care who's hosting. I only care about the interesting content.
If the font of an academic book is Comic Sans, most will be immediately put off about its content. You haven't read a word, but it's already dubious. The medium is the message. Obviously, whoever put the book together doesn't know what the font intrinsically communicates. Doesn't know that Comic Sans is terrible for long reading sessions. The publisher has not bothered to open classics in the genre to compare the formatting. It automatically makes you question the content. One wonders if the publisher paid as little mind to fact-checking the content as they did to the layout. Presentation matters. It's like hating a song because the instruments are out of tune - who could argue with that? I lived in a co-op building before. We had to volunteer. A lot of it was gardening - trimming hedges and such things. I complained to a chill guy that it all felt pointless. "We're doing all this work, these damn plants will just grow back, and all this is about is aesthetics." "Aren't aesthetics really important? " He asked. "This place needs to look like somewhere people want to live." I felt dumb. Of course they matter. People don't go to Paris for the people. To clarify, I'm not complaining about the looks of the presenter, which are fine (though a septum piercing is a snot collector), I'm complaining about the delivery style: The mannerisms, speaking rhythm, and body language.
Clone42 I believe everyone's opinion is valid. Therefore let me tell you. First, I think that the looks of the presenter are of her/his opinion. One can criticize contents and even behavior but not public image, you either like it or not. About the mannerisms, I believe this campaign against excessive acting has gone a bit far. We could argue it, but in the end it would probably get to opinion. The flickering you talked about didn't bother me at all. Of course, I've seen better presentations but it seems an exaggeration that you couldn't finish the video. Content is also important, aesthetics aren't everything. You could read a book from nietzsche even though it's clear it could have been written in a lesser complex and more attractive way. The type isn't the content. Finally, I think you could give some advice instead of... You know. One could say: I would like better the video if you were more natural. Furthermore, if I were you I wouldn't state my opinion as an absolute truth (you actually did that pretty well, from my point of view). Remember this is my opinion. I like the content, it's interesting and nicely explained. The outer layer is your thing.
I didn't address the "looks" of the presenter at all, so I don't know what you're harping on about. I said she could dress in a garbage bag for all I care. Her "looks" are a separate topic from her mannerisms. "The content is interesting", that is just an opinion. To someone well versed in the behavior of light spectrum as it travels through mediums it is not interesting. 'Nicely explained' is also your opinion. I find it hard to learn from someone bouncing on a trampoline waving their hands around for no reason. There may be 0.01% of people who love the sound of a de-tuned symphony, but symphonies always make sure they're in-tune. Is it an opinion that in-tune symphonies sound better than out of tune symphonies? Can that be a fact, or is it still just opinion? Even though there is mathematics to support the tuning, and why it sounds better when in-tune, it's still an opinion by your criteria, because one person in the audience might like de-tuned spectral music. If you really try hard enough everything can be an opinion, and nothing can be objectively true, so conversation is absolutely pointless because it will always end with "we'll agree to disagree.", at best. I guess we'll all just stop exchanging ideas and live out our lives silently in our "it's my opinion" bubbles.
Olivia does everything really well. The only thing is that her hands sometimes move as if they're connected by a string (like, they move together in the same direction), which can be okay, but sometimes it feels like she's just moving her hands without emphasizing anything. I think too much motion can be distracting. Her enthusiasm is nice, though.
What would the world look like if we could see every color on the electromagnetic spectrum? Considering that we only see a fraction of a fraction of it.
Off facebook: "Sky, and what are in the waters at the moment. Your teacher says that [oceans are blue because it reflects the sky], because water is mostly a mirror. It reflect the sky. But water is also translucent. So it has whatever is in the water. Just think water as a liquid, plastic mirror."
I know many US Navy guys who would argue that deep water is green. When you're in a storm, and your ship is deep in a trough, the water on either side of you is green. That's why the common insult to the US Coast Guard is the "Blue Water Navy", since they rarely go out to the deep, green water ocean.
The lake/water outside my home varies in color. If you look straight down at it I looks like it's true color. It's clear to brown and even green depending on the season. In the winter it's more clear and in the summer it's brown or green due to mud or algae. However if your observing it from an angle it will reflect. The reflections depend on whatever it's reflecting obviously. Sometimes the surface appears to be blue on a sunny calm day. Other times it appears to be brown if it's windy. On some occasions it looks silvery on hazy days. On hot hazy days in august it can appear to be super silvery. Now being under clear water with no particles it can very for some of the same reasons. Ocean water tends to have less of these contaminating particulates and filters out other colors of the light spectrum besides blue.
Forgot to mention that the sky doesn't look like a bluish-violet because the sun doesn't produce very much purple light, but a high proportion of blue photons. In fact, the majority of the light the sun generates is blue.
To quote the What-if (#141) "Normal light interacts with the atmosphere through Rayleigh scattering. You may have heard of Rayleigh scattering as the answer to "why is the sky blue." This is sort of true, but honestly, a better answer to this question might be "because air is blue." Sure, it appears blue for a bunch of physics reasons, but everything appears the color it is for a bunch of physics reasons." So actually it is better to say that both the ocean and the sky are blue, because both water and air may look transparant/colorless, but both are blue.
Have you done an episode on why the bubbles in a Guinness seem to go down? Actually, the whole beer-brewing process would be fascinating to see an episode about
Also, I read that heavy water (made with Deuterium I think) doesn't have this dip in it's absorption band. So that would mean that, in theory, if our oceans were made of heavy water, the ocean wouldn't be blue.
Air is mostly inert gases like nitrogen which we eventually exhale without any reaction taking place even if they do dissolve into our blood through our lungs. Reactive gases in air other than oxygen, like carbon monoxide or ozone are generally poisonous. Of course, we can also inhale chemicals like nicotine or nitrous oxide which react in many different ways when they get inside us.
I thought the green colour as shown in the photo there was mostly a result of yellow light being reflected from the sand combining with the blue of the sea to make it green
Ok... so.. here's a question. I grew up on the ocean... I would barely call it blue.. like.. nearly black.. now.. there seems to be a correlation between how far north or south you are from the equator vs the colour of the ocean. Tropical waters are almost always a lighter blue.. like.. you can almost tell the temperature of the water by its colour.. why is that?
Now we need an episode explaining why the oceans are 'Aqua", not "Blue". And check out "Mt Gambier Blue Lake" if you want to see this colour phenomenon at it's extreme.
Hey can you guys provide a video on the FODMAP diet and or irritable bowel syndrome? I think it would be beneficial for people to learn about as so many doctors are currently diagnosing individuals with IBS and are prescribing the FODMAP diet without explanation of how it works.
Could you nice people, please explain to us the what happened with the wolves in Yellowstone? I have seen the film and understand what it says but I have also read an article kind of debunkes the study and its results. It would be helpful with some more info on the subject. :)
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water
If you look at the ocean near land it'll reflect the colour of that land - brown dry fields, green trees or even deep ocean looks grey under grey clouds. Not saying you're wrong, I'm sure you're right but the colours dominated by what it reflects if there is something to reflect...and there's always something.
The way I understand it, the color an object looks is the color it reflects, so I don't know why all that talk about red light being absorbed while blue light wasn't was necessary. Water is blue if it reflects blue light. Glass doesn't absorb blue light either, but it isn't blue...
That fish animation was pretty cool
I thought it was rather erm... fishy not sorry

Nagh! It reminded me of the evil looks of Angler Fish!

Before watching, let me guess: Because the blue color reflects from the sky?
Edit: Goddang it.
In hindsight, I suppose it should have been obvious because indoor pools look blue, too.
Thought that was because the tiles were blue, or chlorine.
Given that the ocean is a completely different shade of blue (more like cobalt rather than sky blue), it should be pretty obvious that it's not just reflecting the sky. Not to mention that whenever you see pictures/footage from divers inside the ocean, it's still blue.

The blue fishy scene was terrifying. Thanks for reminding me of my thalassophobia.
And here in England, the sea looks a dull grey.

Hey SciShow! Here's a science-y question for you!
How the heck do those color- blindness glasses work?
The sky used to be beautifully blue but now is sickly, whitishly blue.
I hope people are nice to Olivia today. She's doing a great job!
I honestly don't know why she isn't liked, she's lovely
She's a great host.

I didn't like her at first, but she's starting to grow on me.
That slowly approaching fish was legit scary tho
So if i shone a white light through a really long glass container, at the end I'd have blue light coming out? Oh cool
Short answer: Because water is blue
The Business Cat ummm water is clear
The Business Cat you didn't watch the video.
The Business Cat if I was green I will die
Just as normal glass is slightly green, water and air are slightly blue. Only a perfect vacuum is clear.
@@mzr.3620 You didn't watch the video. Either that or you weren't paying attention.
I had a feeling it was something different than the sky itself because the ocean is still blue under grey skies.
You know what's also cool? If the oceans were made of heavy water, they'd be pretty much clear. Heavy water is clear but normal water is a very pale blue. Shallow bodies of water would just have the color of whatever's on the bottom or in the water column.

"Blue light bounces off of air molecules better than other light."
Air is blue. Water is blue. Done.
Forgot to mention that the sky doesn't look like a bluish-violet because the sun doesn't produce very much purple light, but a high proportion of blue photons. In fact, the majority of the light the sun generates is blue.
Been wondering this for a while actually, so thanks. Also, glad to see more of Olivia. Keep up the good work, guys.

Why does water flowing out of a faucet make hissing sounds if you set the flow rate a certain way?
Welp, now I'm going to have nightmares tonight about Monster Fish eating Blue Fish.
I think the water in a river can also be brown from the tannins of plants?
Why have I never wondered this before? It seems like a question I should have asked ages ago.
Have you done an episode on why the bubbles in a Guinness seem to go down? Actually, the whole beer-brewing process would be fascinating to see an episode about
The sky is blue because air is blue. Rayleigh scattering is just a reason for why a color exists.
Also, I read that heavy water (made with Deuterium I think) doesn't have this dip in it's absorption band. So that would mean that, in theory, if our oceans were made of heavy water, the ocean wouldn't be blue.
I got in an argument about why the ocean is blue today, and now I know I was right, :^)
Olivia actually is getting better. she feels more natural in this episode
booyah990 she's always been this way. She's great and also cute
booyah990 uglyass millennial
What is she getting better at? Looking homeless?
+Ryan Roberts rude
booyah990 Olivia is Sci-Waifu
bro i was waiting for that little fish to be eating lol
i think the more important question is why are my socks red when i bought them originally white
She's looking much better on camera lately. Did they change equipment? Lighting? What's going on?
Here's a question: Since the atmosphere isn't only oxygen when the other gases enter your lungs what happens ? Are those gases used?
Air is mostly inert gases like nitrogen which we eventually exhale without any reaction taking place even if they do dissolve into our blood through our lungs. Reactive gases in air other than oxygen, like carbon monoxide or ozone are generally poisonous. Of course, we can also inhale chemicals like nicotine or nitrous oxide which react in many different ways when they get inside us.
Karma Arachnid thanks 🤗
so, would that mean the sky is more blue around large bodies of water? do to it refracting the blue light that is reflecting off the ocean?
I thought the green colour as shown in the photo there was mostly a result of yellow light being reflected from the sand combining with the blue of the sea to make it green
Ok... so.. here's a question. I grew up on the ocean... I would barely call it blue.. like.. nearly black.. now.. there seems to be a correlation between how far north or south you are from the equator vs the colour of the ocean. Tropical waters are almost always a lighter blue.. like.. you can almost tell the temperature of the water by its colour.. why is that?
Why does walking in circles help you think?
circulation of body means circulation of ideas (jking)
The bigger fish slowly fading in is as close as this channel gets to real nightmare fuel. That was creepy.
That was more interesting than I anticipated. (Not that I anticipated it being uninteresting, it was just more than I expected.)
Space is water. Outside of the firmament (which we can't leave) is all water.
Hey I have a suggestion how about natural and unnatural flavors in food
Imagine if the water was completely clear
Ocean is blue because water is blue. Mind Blown.
because all the fish in the ocean go bluue bluue bluue blue
Now we need an episode explaining why the oceans are 'Aqua", not "Blue".
And check out "Mt Gambier Blue Lake" if you want to see this colour phenomenon at it's extreme.
The reason people don’t ask this question is bc most people don’t live on the coast( except for lakes and rivers )
What will happen when a crane on a truck hooks up it's own front wheel and starts retracting the rope ?
a big field of snow looks white because it only reflects the white part of the blue sky
Hey can you guys provide a video on the FODMAP diet and or irritable bowel syndrome? I think it would be beneficial for people to learn about as so many doctors are currently diagnosing individuals with IBS and are prescribing the FODMAP diet without explanation of how it works.
Why does the sunset make the sky orange, purple, gold on such a large area of the sky.
Did you guys record her mid-braiding her hair?
Could you nice people, please explain to us the what happened with the wolves in Yellowstone? I have seen the film and understand what it says but I have also read an article kind of debunkes the study and its results. It would be helpful with some more info on the subject. :)
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water
If you look at the ocean near land it'll reflect the colour of that land - brown dry fields, green trees or even deep ocean looks grey under grey clouds.
Not saying you're wrong, I'm sure you're right but the colours dominated by what it reflects if there is something to reflect...and there's always something.
where do trees get their mass from?
I have a question, why have creatures gotten smaller since prehistoric times, such as the megalania
Brackets have a lot on their minds.
If shorter wavelengths scatter more, then why isn't the sky violet instead of blue?
It's the same reason that the center of icebergs are dark blue
I have a question, how can things be clear?
Oh shit you're back, welcome back
I wish these videos had a short answer at the top of the comments
I saw that. : )
"Why is the sky blue around my..."
The way I understand it, the color an object looks is the color it reflects, so I don't know why all that talk about red light being absorbed while blue light wasn't was necessary. Water is blue if it reflects blue light. Glass doesn't absorb blue light either, but it isn't blue...
The same sea looks black during rain time pls do explain
i was expecting that big fish to eat the little one ...
3 hours ago I was hoping you guys would one day make a video on this.
So the answer is: Because the ocean is blue. That's awesome!
