How do the layers of the ocean mix together? The energy put in by the winds and tides is less than what’s required for the amount of mixing, so what else is bringing the mixing energy? Turns out, it might be very active anchovy reproduction.

I would argue that krill would still cause biomixing because of how many other creatures feed on them

~ the Anchovies
That was funny, good one.
Hee hee, Instead of a butterfly-effect, it is the Fish-bone effect
Hee hee 😂
Hank saying "anchovy sex" right as I took my first bite of a Caesar Salad was perfect.
Unless spelled out: Seizure Salad? or Seize Your Salad?
Quite different outcomes among the illiterati.
Spelled out, we DO retain some difficulty in discerning whether Dog Whisperer, or some "I et, too, Brute" composed or consumed salad.
I've never seen an anchovy, i thought it was a weird vegetable people don't like on pizza. I didn't know it was a silvery European fish!
Check out the Cloudy with a chance of Meatballs movie lol there's a famous anchovy
But people *do* like it on pizza. We're just scared to say so in public because the haters are so militant.
@@tinkergnomad You haven't seen the futurama episode, have you?
I grew up watching spongebob and Futurama, so of course I know what anchovies are 😂
Wait till you see iceberg lettuce, it's gonna blow your mind. Spoiler * it's nothing to do with ice. 🤯
My bad, I have bad form when swimming
“It was you!” -Dracula
You've had your fun. Now it's my churn.
That is some epically bad form their, my friend!
Yo mama so fat she dove in the ocean and now the layers are mixing
@@kurocknotabi 10/10 :D
Gotta say, I was definitely not expecting to hear "ANCHOVY SEX" this early in my morning....
and I also think it's absolutely wild that anchovy eggs develop in SIXTY HOURS?!??! Talk about life on the fast track??? I didn't think any macro-sized organisms could develop that fast!
Calling anchovies "macro-sized" is hyperbole on your side. But they're definitely macro in flavor.
@@LuisAldamiz They're not microscopic, was what I meant, haha. I don't think I've ever eaten them.
@@Beryllahawk Have you ever had a Caesar salad?
@@SaruCharmed Nope! I've seen the American version, which doesn't involve any fish, but I do know of the "actual" version, and also the Nicoise salad. Just never tried them. I might go look for anchovy filets soon though!
@@Beryllahawk Even in America, the dressing is made with anchovies. I think most people who have them don't even realize they're eating fish. It doesn't taste fishy, just salty.
Somewhere I read approx " the most exciting sound in science is not 'Eureka' but 'that's weird?' "
pretty you all just proved that.
I actually shouted "What?!" when the Bizarre Beast's name was revealed - I was not expecting that all! A very good video about a bizarre scientific theory that I would have never guessed in a million years!
Lol me too!
Fun Fact: When Hank said that the early relatives of the anchovies had saber tooth, he referred to the Saber-Toothed Salmon, which was quite large, **and yes, everything in the Ice Age had to have huge teeth and ivories totally not to dig up stuff or use em as knifes :]**
Since i have consorted with sabre tooth kitties of up to 30 million years of age, may i suggest that your presumption of ivory tickling's limited existential span, similarly to pretensions of many youtube commenters on music, may be woefully limited.
Season 0 was fun and necessary for factual accuracy reasons, but im glad were back to regular Bizarre Beasts, the production is pristine
I'm new to this channel. What's this mean?
@@morg630 season 0 was a recap of all the animals Hank originally talked about on the vlogbrothers channel, with scientific accuracy updates
@@Chrismas815 i see, ty

Took too much scrolling to find this tbh
Spongebob reference? 👍🏻👍🏻👍🏻👍🏻
Call them anchoas, call them boquerones, all them will fall for the taste (they don't smell that much but the taste is very intense).

REAL TALK:
How many different science-communication channels am I going to click on only to be greeted by this man once again? YOU'RE EVERYWHERE
Hank Green or Simon Whistler, you’ll never escape them
@@mcpudd1540 were you trying to? I mean, you're right, but it's GOOD copious content. 😂❤
It's either him or Simon whistler 😂 I'm not mad though!
"The physics of the ocean is about to get freaky"
Some Anchovies probably
Let's not forget that there IS a significant source of heat energy at the bottom of the ocean - geothermal vents. I'm going to give the benefit of the doubt and assume that this was taken into account in modeling because it seems too obvious to miss.
Not where the data was collected. Geothermal vents are in the mid-Atlantic Ocean ridge, i.e. between Iceland and Azores, not so close to the coasts.
There are plenty of people taking thermal vents into account, but iirc they're not a significant source of mixing globally (I would guess just because there aren't enough of them, not quite my area). It's actually been proven since Sandström that you don't need the heat source to be below the cooling to achieve convection anyway
@@LuisAldamiz Google "map of geothermal undersea vents for the fastest proof of how wrong you are. Not to be a tool, but that was just very wrong. They are literally everywhere there is a fault line at sea, which is all around the world, and MANY of them are quite close to shore.
@@WrenStuart-y9h There are over 500 KNOWN vent fields, each with many many vents spread over hundreds of miles. But they absolutely ARE a significant convection source anywhere they are. Most of them were discovered because of the large plume of warm water they sent toward the surface. Can you cite a source that says they are not a significant source of mixing?
Not my field either, but that is truly counterintuitive. If you've ever seen one in action in person, just one vent in a field can be sending tens of thousands of gallons a minute from the floor to the surface...... but that's less significant than fish swimming up and down a few meters at a time?
@@backpacker3421 - I did search for those maps (Startpage rather than Google, I've been trying to de-Googleize for very long now) and they totally confirm my previous beliefs: hydrothermal vents are along the mid-Atlantic ridge (the "wound" as Afro-Eurasia and America(s) pull apart from each other) and NOT near the coasts.
This IS going to be one of the best pins you've ever made. It will have such a place of honor on my ocean pin banner, amongst the sharks and kelp pins, and of course, my favorite of all time -- the Bizarre Beasts hagfish pin.
This is hilarious and indeed bizarre and you've significantly contributed to my mood. Thank you so much for that!
nothing - and i mean NOTHING - prepared me for the reveal at 0:49
Hank really said "anchovy sex" with such strong, consummate professionalism i had to pause and let it echo in my brain
I thought anchovies were vegetables when I was a kid. I know they're not, but my brain always autocorrects when I hear the word. So vegetables mixing the ocean.
My brain always thinks of green olives when i read anchovies
thats incredible. would never have thought such a small fish could have such a big impact
It seems to me that every creature in the ocean would help to do the mixing, with some doing more work than others.
The ocean has a lot of thermal vents that create the convection from the bottom that helps to mix things. The salt content may also be a factor for mixing things, different densities different movement.
All in all I think its the entire biodiversity of the ocean along with tectonic shifts under it and of course the tides that gives us our beautiful oceans instead of giant lakes of stagnant water. And that, my friends, is a very good thing!
Not at those locations.
I believe there are underwater currents too. And icebergs .
Animals unintentionally maintaining their environment.

The opposite to humans
As someone who used to get punched in the head a lot for some extra spending cash, I feel like chins are an easy solve, namely, we have them to protect the teeth and mouth, same reason our cheeks are fatty and poofy, and the eye orbital and other parts of the skull extend out over where the teeth are placed. Makes it so it's basically impossible for an adult human fist and similar sized objects to connect directly with our very sensitive and irreplaceable teeth so long as the mouth is closed.
Still the best video series on the internet. And the best day of the month. I truly love you guys.
Poseidon, of course
Though his anchovies, of course.
@@thekaxmax Olympus works in mysterious ways
I did not expect that reveal. I had to sit down from giggling too much
things were said in this video that kept having me thinking "well I didnt expect to hear that today... or ever"
1:09 to 1:11 we all agree it’s so good
I learn more from Hank Green than my Oceanography professors
The fact that ice floats means there's convection even when the heat source is from above. The temperature cannot stratify when the coldest part is forced on top.
This is a literal case of the butterfly effect
The anchovy effect
I subscribed to the pin club last month especially for the hyrax and i got the rare one with pink sparkles! i love hyraxes!!
As a commercial fisherman, all the fish in the ocean, stir the ocean just by swimming
my theory on chins is just our teeth being so sunken into our face but the rest of the face did not keep up, sort of like our nose is part of a muzzle that did not get shorter in length and just had to curve along being pulled by our jaws inwards, there is no reason to really evolve away a chin so it stays there its also as a expressive and acts as more protection for our teeth it takes the hit, it also makes beards look bigger due to the curved surface angle
We love you, Hank. We love you
in the ocean streaight up "doing it." by "It" lets just say. My Chovies
I had this on my watch later playlist before you changed the title and thumbnail, so I had the question raised and answered before even watching it
Ruling out heat from below is a wild move. Especially with the extreme sea temp spike that can't be explained by greenhouse or solar activity.
The brine shrimp time lapse looks like a Van Gogh
Just keep swimming... just keep swimming...
Or the ocean dies.
Anything Hang Green - Never a disapointment. :)
People will never look at pizza the same way again.
When i first heard about this problem, my immediate reaction was "well, animals exist, surely that should play some part in mixing". Was not expecting specifically mating to be the answer xD
At first the 'anchovy sex' was a bit funny..
Then after reading comments it was quite funny :D
Then i realized im currently eating fishsticks.
Step aside, Butterfly Effect. It's the Anchovy Effect's time to shine.
Instant classic fish video 😄 right up there with the deep sea anglerfish
I'm doing phd at the place where the study was conducted (very unrelated topic) and I had no idea this happened! I´m gonna have to go pester some people at the institute
I still love Hank's new hair - I know it came at a great cost but it rocks ❤
WHOA, I was not expecting that right out of the gate! 😮
New pick-up line for the sexy science nerds: "honey, our love making will be worthy of the anchovies: powerful enough to stirr up the oceans!"
Now I'm going to feel guilty when I open a tin of anchovies for lunch.
0:52 i almost choked on my food
Shout out to anchovies. I love anchovies, sardines, and all types of canned seafood. A lot of people think they’re gross but that just means more for me!
Thank you, anchovies. Keep mixing ... work and pleasure.
Ah humans... We ruin everything.
"We are the virus" mfs when a well executed prescribed burn walks into the room:
Anchovy paste adds depth of flavor to food.
Once again petitioning for an episode on flying squirrels!
Out of curiosity, wouldn't "...energy was lost as heat before moving much water" contribute to convection currents? I know it takes a considerable amount of energy to warm up water, but could even those small amounts meaningfully contribute?
I'm surprised we didn't talk about like... the rotation of the earth, or the constant movement of the tectonic plates. It seems to me that new materual coming up out of a fault is Quite Hot and shock cooled upon contact. The substrait beneath the water itself is constantly edging along microns at a time. I imagine that's gotta send some energy into the water that causes churn.
I'm not saying the anchoveys don't help, I'm just surprised that in looking for the cause of motion for a large mass of water, we don't look at the proverbial container its sitting in and what forces its contributing from below. Like... idk, the kinetic energy from the entire mass of the planet spinning?
5:10 the team had a what...
I'll see myself out
So love really does make the -world- oceans go around.
Uh-oh, guess no more anchovy pizzas, LOL! Seriously, that's totally cool!
I mean, I would also assume that the constant movement of the animals in the ocean as well as things like thermal vents... anchovy sex wasn't what I had in mind, but it will now be a permanent scar on my psyche
The fish in your deepdish makes the motion in the ocean.
This has serious ramifications for the Futurama universe.
I feel like Hanks vibe is different in this video. I like it. Might be the curls.
that was not in my mind when I opened my CZcams for tea today, but well...
The mighty anchove

Pls, do one about the sea bunny. 🙏 I know you did one about the leaf sea sheep, but it is sooo cute and "fuzzy". ❤❤❤🐰 I think people would also love it.
I agree
Fascinating. Anchovies are God... or at least Neptune. Let's not overfish them, OK?
Mixing it up and getting it on
They had ONE fang back in the day?!? I need to know more about this! *runs to internet* Asymmetrical animals are so fun. You should look up huia birds (well you can’t since they’re extinct, but very cool flappers)
Anchovies? More like sea buffalo.
How about under water volcanoes of witch number in the thousands?
Not in those locations. Know your planet, Earthling.
Only thousands-- they are a tiny part of the sea bottom. And were included in the study
underwater volcanoes pale in comparison to how big the oceans are
You guys should team up with strangest thing I learned this week.
Biomixing makes perfect sense to me, i guess the only thing thats so bizarre is that we think fish are so small compared to the worlds oceans, but yeah, considering the sheer amount of life, it just makes sense.
Lantern fish tho. They ascend and descend every day. And they're so abundant that they initially altered ocean floor readings.
My question is, ocean predating complex life on earth, was the ocean still then or having more distinct layers ? And is it necessary in this case to have relatively still oceans to see life develop in a meaningful way?
Rather than anchovies, maybe it's the bristlemouth fish that contribute the most to ocean mixing? After all, there are an estimated 1 quadrillion (million billion) of them swimming about in the mesopelagic zone.
Hey Hank, as you mentioned SciShow: Eight days without new videos, what's up over there (or isn't)?
Here is my comment for support
“Sounding instrument”
Me: Internet flashbacks ptsd
Whoops, sorry about that. Accidentally sunk a boat full of immersion blenders
Love makes the world go around, for now at least.
talk about the butterfly effect! I’ll never see anchovies the same again.
You should ask how are we fixing the dead zones fishing ships have made
So what Hank is trying to say, it’s not the size of the animal. It’s the motion of the ocean.
thank you for such an amazing content. channels like these enormously increase bioconscience
ARE THOSE PRIDE ANCHOVY PINS?? I WANT TWELVE!
Fish are efficient swimmers, they don't want to affect the water much, they want to use as little energy as possible to move through it.
Look up "salt oscillator". Quite a lot of mixing is due to salt, which is very important as Greenland melts and makes the water more fresh, it's messing with the mixing. Also marine snow might drive some convection
But they can't help it: water is a very dense material which has to be displaced (as efficiently as possible but still needs displacement) as you (or your pet anchovy) swims.
It sould be due to the daily migration of tiny creatures coming up from the deep at night and returning to the deep in the morning.
Oh, you cover that ((Diel Vertical Migration).
The collective effect on ocean mixing of all sea life practiing the DVM is reminiscent of humans' collective effect on the world climate as a result of our daily actions, especially those involving fossil fuels.
Dope
Cool
My favorite snack!
terima kasih😊😊
"A Bunch of Anchovies" is the name of George RR Martin's next book
Was the presence of geothermal vents at the bottom of our ocean considered for the convection theory?
interesting... so our over fishing is (jsut fishing in general IMO) is an energy drain in ALL ways. .. great(/s)
how do we get more people to change their world views. to get a better, earth based paradigm? i'll even concede that an earth based paradigm is discriminatory to the our solar system, and other solar systems and ultimately the universe and any other universes... because if we can't even care about one planet i dont see the general public being concerned with damaging the fabric of space time with warp fields .
( sci-fi, but the fact that we have thought of these stories already, as analogy for burning fuels... is a huge concern in reality. it is the forward thinking we really need )
