When I heard about this I also heard about the deep sea mining of these nodules, and I thought to myself "oh no, we're going to destroy something else that made our existence on Earth livable, aren't we." Hopefully with scientific research, lawmakers can use the evidence of how vital these ecosystems are to restrict mining. Hopefully.
The more people know about it the less likely they'll get away with it, tell your friends, family and strangers about how important deep sea nodules are!
@@ethanstyant9704I'm pretty sure it was called dark matter because, other than gravitationally, it doesn't interact at all with regular matter or energy, including light, rendering it invisible and therefore, against the black background of space, dark.
Bulldozing the ocean floor sounds like a bad idea. Once it starts it will not stop. Think about the company that is mining minerals the old fashioned expensive way watching another company scoop it up for half the price. What is that company going to immediately do when metal prices drop?
Looking at the political side, how do we decide who gets rights to mine these deposits anyway? Like, a mining company in the U.S. leasing out the mineral rights on U.S. government land is one thing, but I’d imagine that almost all of these deposits are in international waters. Do we just do an Antarctica and give the biggest countries what they “deserve” or make some mineral claim that doesn’t just effectively extend territorial water? Even if we surpass (or just blatantly ignore) the environmental and ethical concerns facing underwater mining, it’s sure to cause plenty of international conflict.
and, of course, it's not cheaper. It's probably magnitudes more expensive, just shoving most of the cost out and away, into the future, for worse-off humans to pay back, _with interest,_ later
One could argue bulldozing large swaths of ANY ecosystem (ie; um, everywhere) is a very bad idea. It is a short term "solution" to things that shouldn't be as large of a problem that they are... but, ya know, money to be made and stuff.
@@Pawsome_Opossum Don't forget the sheer amount of companies that'll just start mining without even asking for permission, since it's conveniently difficult to track such operations out at sea
Even as a boy who had read the stuff about the deep ocean metallic nods, I had always felt that those metallic nods were somehow connected to the life surrounding it. Now, we finally have found out that those are the oxygen generators of the deep ocean. Based on this information, deep sea/ocean mining is not just harming the environment. It basically removes the most important thing that deep ocean life depends on. Deep ocean mining is killing off any chance that life can live in the deep ocean.
it's really really weird, growing up as a science- and space-obsessed little boy, that I learned about electrolysis primarily in the context of fuel cells, metal plating, etc... and now that I'm an adult trans woman, people think the term applies only to the hair removal technique, instead of meaning "to put some electricity in there"
'Building better worlds' I don't know if there's something in the 'Alien' lore about the origins of Weyland-Yutani, but it would be fitting if they started as a deep sea mining corporation.

Not even physicists are sure what dark matter is. Other than they can't see it, and when they add it into the equations, it makes things work out. "So, it's like a fudge factor of 75%?" "No. It's dark matter!" "So what is dark matter?" "We're not sure, but trust me, it exists." (personally, I think it's a range limitation of the quantum gravity particle, like the range limitation on the strong force. At least, that's what my back-of-napkin calculations show...)
On land metals rust and dissolve in water. This is because the atmosphere is rich in oxygen. The water goes out to sea. Sea water is salty, which is like the mid step in a battery. The metal plates out because of the pressure, releasing the oxygen it brought with it, and in the process makes the nodules. How deep into the sea floor muck do the nodules extend? That they are all about the same size indicates some sort of stop point in their growth. I suggest sediment covering the old ones, and micro-meteorites becoming the nucleating points for new ones. To prove this, we gotta dig a hole. Cut me in as a consultant on the grant proposal.
while superficially it seems like that, it's more like the invisible atmosphere between you in your house, and a tree far off in the outside world. It's most definitely there, it's the only explanation for how half a dozen categories of deep-space observation get fudged up like that, and it's only mysterious if you phrase it like "an invisible substance somewhere between your eye and the tree in the distance, that fills the vast majority of the volume of the whole world, that doesn't reflect light at all, and magically makes equations work if you add it to them" like, sure, that's A way to describe it, but you're missing 99% of the evidence incontrovertibly proving there is SOMETHING, whole huge nebula-sized clouds of SOMETHING there that's messing with light in transit, and simply not reflecting any light of its own!
Dark matter is something that has gravity like normal matter but doesn't interact with light. We can tell where there is more or less of it and it's locations (particularly where it ends up after two galaxies collide) are most consistent with it being particles that barely interact with each other either.
@geraldfrost4710 oh also, it's definitely not a "range limitation on gravity of ordinary matter" because the issue SPECIFICALLY is that the ordinary matter we saw would generate TOO LITTLE gravity in simulations compared to what we observe. We need MORE gravity to replicate observed reality, not less!!!

firstly gotta love the babymetal mention, and the last week tonight mention (love them both), secondly did i just see a living organism at 4000m that looks like someone took a bundle of sticks and stuck tennis balls on the ends??????????? anyhow another rlly interesting video
YES! thank you for this! i love hearing you explain things and i’d heard about this but felt out of my depth, also life has been in the way more often than not.
Awesome video! I saw posts about it last week and I literally thought "damn this looks deeply interesting, I wish there was a digestible way to understand the implications" and this is just perfect. So nicely explained and edited, with really good vulgarization, thank you for your work!
This is all very interesting and unexpected. The first question that occurred to me was: If dark oxygen is being produced by electrolysis of water, then there should also be production of dark hydrogen--something to look for. There's a lot of interest these days in ways of generating hydrogen to power fuel cells and other applications, and it is turning out that hydrogen is being produced abiotically in places people had never thought of looking for it. Interest in mining the manganese nodules (as I'm used to hearing them being called) was very high in the middle 1970s, about the time I was receiving my Ph.D. in biological oceanography. I spent several months on a NOAA cruise to the area in question, doing baseline studies of the environment before manganese nodule mining could begin. In particular, Howard Hughes was spending massive amounts of money developing a giant nodule harvester, which would float on the surface and send what was essentially a giant vacuum cleaner down to the ocean bottom to vacuum up the nodules to the surface. It turned out that Hughes's project was actually a cover story for the CIA, which used his rig in an attempt to recover a Soviet submarine that had sunk in the deep ocean. The sub broke in two as it was being lifted to the surface, and I don't remember if they were able to recover any part of the sub. But the whole escapade pretty much ended serious interest in manganese nodule harvesting, at least for that time. The nodules are still there, and I suppose someone will figure out a way of making money out of them.
Another fantastic video as always! You explain things in such an easy to understand way, and I always get a good chuckle out of your edits and humor. Hope your health is holding up
They were so close to greatness! Why couldn't they have added "Emission" or something like that at the end (I don't know which words would qualify)? Then it would've been DOPE.
Ahhhhh i love your Videos soooo much! I am jumping in the middle of the night with joy about someone else having the same enthusiasm talking about oceanstuff!
If I'm not mistaking, some metals like Osmium are actually used for electrolysis, so it makes sense that clumps of metallic minerals under pressure would eventually act as mini batteries. As for deep sea mining, I'm not a specialist but anything related to the oceanic floor is very expensive to operate and maintain. Mining companies won't rush there until it becomes very cheap or if for some bizarre reason, land mining became prohibitly expensive. Can't wait for the space age to fully kick where we might be mining asteroids instead.
Love your channel! I would really love to see you cover Oarfish. I feel like theres nothing quite like Oarfish and they have so much lore surrounding them!
This is precisely why I find science so fascinating. Chunks of metal at the bottom of the ocean acting like batteries and making oxygen? So cool. We should definitely leave these places alone.
0:50 physicists also don't know what dark matter is, that's why we call it dark matter. Pretty much the only thing we know about it is that it exists (probably) you can't see it (probably) and has mass (probably)
Hey those are the same nodules resource companies are lining up to scoop up for refining, Imagine that. Tio2 casually splits water molecules as a Valve metal. Its in some obscure text book somewhere no one looks at thusly mostly forgotten by whom it may concern. it does that and can produce electricity with the right configuration. Also crystal rust batteries are a majority magnesium and can work over a really long time.
ya know, maybe nodules would be a good sign of oxygen or life on other planets like Mars, if they find nodule like rocks or patterns on what could be ancient ocean beds it could be sign there was oxygen and life, so finding out about these here is a good sign of life out there as well, and destroying them just for our needs sure is a sign that we are in need of deep therapy
I love all of your videos! I was going to go to Texas A&M at Galveston to be a marine biologist. But my family moved to Arkansas! ( And I was very poor) So, I became an R.N.

I didn't even know deep sea mining was a thing. Thank you for the information. I will look into it more. Seems like that could create some nasty effects for the whole ocean.
This has huge implications for chemistry on other planets, and could shape how we search for planets/moons that might support life, assuming this hypothesis turns out to hold water.
@The Octopus Lady, you forgot to mention that there are companies that want to mine the ocean floor for those nodules, and kill off any oxygen production.
Sickening this content got under 100k views. This platform for sure knows how to driveaway the good content and push the slop. Please keep making these videos you are literally one of the last few youtubers that have real morals.
I thought, for a planet to even have any manganese or iron or heavy metals on its surface, it either needs to get hit with a ton of asteroids for a long time or have had a mars sized object crash into it to mix it's heavy metal core (ours also created the moon). We just don't know if having a trojan you catch up with in the early years of a solar system is bog standard or what.
I was always confused about the deep sea and oxygen as I never heard about any animal down there having an adaptation that allows them to survive without, yet photosynthesis doesn't happen there and I also never hear about oxygen "sinking" to the abyss, and the hydrothermal vents aren't everywhere down there so DOP has the be it I think.

Hey those are the same nodules resource companies are lining up to scoop up for refining, Imagine that. Tio2 casually splits water molecules as a Valve metal. Its in some obscure text book somewhere no one looks at thusly mostly forgotten by whom it may concern.
it does that and can produce electricity with the right configuration. Also crystal rust batteries are a majority magnesium and can work over a really long time.
ya know, maybe nodules would be a good sign of oxygen or life on other planets like Mars, if they find nodule like rocks or patterns on what could be ancient ocean beds it could be sign there was oxygen and life, so finding out about these here is a good sign of life out there as well, and destroying them just for our needs sure is a sign that we are in need of deep therapy
Commenting for the algorithm because I didn’t get notified for this but I’m hyped as heck to see it
Omg thank you I've already binged all your videos
My favorite day of the month is the Octopus Lady video day!🎉
I am here! I am excited!! Octopus Lady has gifted us with a video!!!
8:12 relatable. i hate (tech) billionaires and their greed.
“Cuz im not a nerd”😂😂 ❤
Yaaayyyyyy octopus lady!!! I'm always excited to see a new video from you
I love all of your videos! I was going to go to Texas A&M at Galveston to be a marine biologist. But my family moved to Arkansas! ( And I was very poor) So, I became an R.N. Every one of your videos gives me a a laugh and a smack of joy! I watch you here and on Neb. So you can get the watches for da algorithm.
I went back and watched your coconut crab video, and realized I had a couple of the shell for home sized ones as pets!
😂🎉😂Love what you do, and please keep it up!
I don't know how this lovely octopus got the ability to speak and create youtube videos but I subscribed nonetheless. Thanks, Octopus Lady!
Woohoo new cephalapod women upload
Hell yeah we love headfoot female here
cephalapod person🤯
@@maybe_a_goober who the hell are you? 😭 (lol)
cephalopods are gender
Yippee my comment got a heart
This was excellent, thanks!
Nodule bucket is such a great thing to say. It's the name of my new Drum and Bass song for sure.) Thanks for the great channel. Love the presentation style and the well researched script. Well done.
Thanks octolady, love you!
thank you for another great video!
OL: Oxygen made without photosynthesis...
Me: Ooh, neat!
OL: Which might not sound very interesting...
Me: No, no, that's definitely very interesting.
I love your happiness in your videos
0:57 whoa whoa whoa, look here you Cephalopod, physics is pretty cool lol
Ok. So things that DEFINITELY make O2 on earth:
-plants
-microbes
Things that MIGHT make O2 on earth:
-FRIGGIN ROCKS?!
The nodules and the creatures they likely support MUST NOT be disturbed in any significant way. Thank you for spreading the word.
I didn't even know deep sea mining was a thing. Thank you for the information. I will look into it more. Seems like that could create some nasty effects for the whole ocean.
This goes to show that the deep sea ocean is a eldritch location.
This has huge implications for chemistry on other planets, and could shape how we search for planets/moons that might support life, assuming this hypothesis turns out to hold water.
@The Octopus Lady, you forgot to mention that there are companies that want to mine the ocean floor for those nodules, and kill off any oxygen production.
Oh woah finally seeing one same day it came out. I'm glad I've seen all the other videos
PS - Frustule is a fine word too. Loved the Diatoms video.. Thanks.
OCTOPUS UPLOAD! :D
can't believe this took 10 days to reach me, good video!
Yay! She posted!
Love your videos. I leatn somthing every time! Thank you for doing what you do
“whatever dark matter is” is actually an accurate definition of what dark matter is
Even when the day is bad, i can rely on the funny purple octopus to make me giggle and laugh.
as a fish keeper my immediate thought was, where do I find these rocks?????
Great video, thank you! The fact you mentioned electrolysis makes me wonder if my high school education wasn't actually a waste of time after all.
Excellent video. Thanks.
Korn, Metallica and Babymetal is an excellent combination of bands to annoy metal elitists, excellent choice
Sickening this content got under 100k views. This platform for sure knows how to driveaway the good content and push the slop. Please keep making these videos you are literally one of the last few youtubers that have real morals.
I thought, for a planet to even have any manganese or iron or heavy metals on its surface, it either needs to get hit with a ton of asteroids for a long time or have had a mars sized object crash into it to mix it's heavy metal core (ours also created the moon).
We just don't know if having a trojan you catch up with in the early years of a solar system is bog standard or what.
I was always confused about the deep sea and oxygen as I never heard about any animal down there having an adaptation that allows them to survive without, yet photosynthesis doesn't happen there and I also never hear about oxygen "sinking" to the abyss, and the hydrothermal vents aren't everywhere down there so DOP has the be it I think.
