Scientists discover 91 volcanoes below Antarctic ice sheet - Uncover the largest volcanic region on Earth – 2 kilometres below the surface of the vast ice sheet that covers west Antarctica.

Scientists discover 91 volcanoes below Antarctic ice sheet - Uncover the largest volcanic region ...

I can't wait to watch the inevitable BBC documentary on this

Goddammit they better make it quick. I want my beautiful landscape shots and smooth David Attenborough narration.

Why do you think I put all that snow on top of them?

Don't we have enough source material by now, he can narrate nature for the rest of time.

This article suggests ice sheets may play a role in suppressing volcanic activity. Would any volcanologists care to elaborate?

91 Volcanoes alone under the Antarctic sheet?? That's is interesting, we've populated the world, achieved minor space travel. But we still do not know everything about this little blue marble called Earth.

My take on this article was that if the volcanoes erupt they'll melt the ice, but I'd me more worried about something called isostacy because of the timescales involved. Those volcanoes may not erupt for hundreds of thousands of years in their current state, but if the ice melts first that could change.

Ice isn't as heavy as rock, but it's much easier to build it up or remove it than rock. When you remove 2 km of ice in a geologic instant, the crust will rebound towards the surface. It's hard to predict exactly what effect that will have, but if any of those 91 volcanoes have active magna bodies that get to shallow they could definitely erupt. Would this be sudden or would we have some warning? What effect does a large eruption have as the pole vs near the equator? Hard to say, but large eruptions have had major world-changing effects I the near past.

+Look up Mt Rainer lahar maps to see what happens when volcanoes melt glaciers

+Look up Mt Tambora and the year without a summer for global famine and wars related to large eruptions

+Look up Mt St Helen's for what happens when the side of a volcano suddenly loses its heavy overburden

Well that's just fucking great.

Oh shit, earth is a space ship and they found the propulsion system!

Grand Moff Tarkin disagrees.

Edit: my bad, didn't know he was actually voiced by an actor.

Voice synthesis isn't that good yet.

WE STAND AMISDT MY DISCOVERY, NOT YOURS

The world is insane. While I don't mean to insult any scientists with my comment, it is a bit mental that we were just going about life and thinking that we understood our planet and we somehow missed the presence of not just one, but ninety-one actual fucking volcanos.

Cool demonym

Lets dig them out and see if they still work!

Do you want to wake the old gods? Because this is how you wake the old gods.

and all the shit in the sea we still dont know about

to be honest I'm okay with having a limited knowledge of the sea. it gets very weird down there.

This is the best tl;dr I could make, original reduced by 79%. (I'm a bot)

Scientists have uncovered the largest volcanic region on Earth - two kilometres below the surface of the vast ice sheet that covers west Antarctica.

The Edinburgh volcano survey, reported in the Geological Society's special publications series, involved studying the underside of the west Antarctica ice sheet for hidden peaks of basalt rock similar to those produced by the region's other volcanoes.

"We had not expected to find anything like that number. We have almost trebled the number of volcanoes known to exist in west Antarctica. We also suspect there are even more on the bed of the sea that lies under the Ross ice shelf, so that I think it is very likely this region will turn out to be the densest region of volcanoes in the world, greater even than east Africa, where mounts Nyiragongo, Kilimanjaro, Longonot and all the other active volcanoes are concentrated."

Cool word

He's not just a narrator. The man has been there and done that.

That, my friends, is the voice of a man who has stood his ground when a group of tribesmen in New Guinea charged him with spears.

I think that the massive balls he must be lugging around are surely giving his voice a distinctive resonance.

...Discovery isn't what it used to be

At least it's not the History of Aliens channel.

ELI5: How is "west Antarctica" defined?

Wouldn't the South Pole be somewhere in the middle of the continent, making every direction from there north Antarctica?

Can't wait to watch the inevitable History Channel documentary on the vast underground volcano civilization below Antarctica.

Also, I have to imagine the ice-sheet is keeping the crust in the area generally cooler, creating more resistance against the magma trying to melt away the crust to rise up further.

The topic of how magna moves up through the crust is actually a point of contention in the continuity. It used to be modeled like a blob moving upwards, with large blocks on the roof of the magma chamber falling in and sinking to the bottom allowing the whole blob to rise. Once this blob is in a neutrally buoyant place, it may freeze or it may erupt (or a combination). In the last 15 years folks have begun to ask the question "if volcanoes have large magna bodies under them, why is it rare to actually image molten magma chamber with seismic data?" The alternate hypothesis is that magma moves upwards by taking advantages in weaknesses within the crust to propagate cracks that it can then move through. These cracks are to narrow to image with seismic techniques unless they are very near the surface, so that speaks to that question. The idea is that when/if these cracks all converge at a place in the crust they form a large magma body that either erupts quickly (geologically speaking) or crystallizes.

If hypothesis 1 is happening, then perhaps the ice could have some effect on how the magma moves around, although that's not my area so I'm not sure. If hypothesis 2 is what's happening I suspect the weight of the ice is much more of a factor than the temperature because of how poor rocks are at conducting heat.

And then stuck his hand out and said "Good afternoon."

Huge, huge British balls.

It looks like the time is ripe to take up Volcanology. When I started at uni, 1988, our lecturer said there were about 50 volcanologists in the world. I've never forgotten that. As fascinating as lava is. He was one of them.

It is weird. What happened to those channels. I used to watch very educational shows that I really enjoyed and now it's just crap.

Brb going to go rev my car up for a few minutes to increase global warming. I hope everyone else will do the same.

Volcanic activity under the ice sheets in Antarctica, causing the ice to move and the ocean levels to rise, was the key point in several of Kim Stanley Robinson's Mars books that lead to the colonization of Mars. So, you know, it's not all bad.

A song of fire and ice.

And global warming is the key.

I don't think mammoths thrive under ice sheets or water.

[...] We have almost trebled the number of volcanoes known to exist in west Antarctica. [...]

Trebled? The situation is graver than I thought!

What IS it about his voice? I could listen to him all day. The man's a treasure.

DECOMPRESSIONAL MELTING

(1) The weight of kilometers of ice pushes the Earth's crust downwards.

(2) Remove Ice

(3) Crust undergoes isostatic rebound i.e. moves upwards slowly as nothing is pushing it down. (Side note: Much of the Northern Hempishere is still undergoing isostatic rebound due to the last glacial period which ended 15-20 kya.)

(4) Mantle material (which is hot rock that is not currently magma due to the immense pressure it is under) follows along upwards with the crust)

(5) As mantle material moves upwards it (the rock) can melt into a magma as the pressure it is experiencing goes down. Note - to melt something you can increase the temperature or decrease the pressure. In this case it is possible the mantle material does not change temperature (adiabatic) but due to pressure drop you can melt it.

(6) You now have magma. Be carefaul it may form volcano which can melt ice. Careful you don't melt the ice cause that might cause DECOMPRESSIONAL MELTING again (maybe? I dunno)

It is if you have an immense amount of source material to reference. A new word that he's never said before could be a challenge... But not impossible to clip rhyming sounds out and blend for a word. Tedious? Multitrack nightmare?? You bet. But in a few years we'll just make some AI bitch do the work. Maybe even make a vocoder out if it... so we can all drop panties by narrating about cheetahs boinking on the Savannah or some such topic.

His pacing. Moments of pause, stretched phonemes, and deliberate execution is what I find so mesmerizing.

demonym

a proper noun used to denote the natives or inhabitants of a particular country, state, city, etc.: Tasmanian is a demonym, as is Taswegian, the alternative.

This is such an incredibly intelligent question. It's strange to think that at the pole you can only go north.

Tell James Cameron there's something cool down there. He's down.

History Channel documentary

Good luck with that

He made a bass of himself with that quote. An alto familiar situation.

The baby volcano waits for its mother underneath the water and ice. Only when it is fully matured will it rear its head in a violent display. That display is a message "I'm ready for mating." When two volcanos emerge near each other they become mates for life.

anartica

I'm pretty sure he's never uttered that word ever. Not even whilst drunk.

There seems to be significant correlation between where the volcanoes are located, and where the observed ice mass loss has been taking place in Antarctica.  Have we, perhaps, put the cart before the horse here?

Maybe not an excuse, but they do release a massive amount of crap into the air when they go off. It's not wrong, it just doesn't necessarily have any bearing on a discussion about human pollution.

Geoscientist here. Not offended, it's why we do what we do! If everything had been explored Earth sciences in particular would be super boring. Imagine being an undergrad and getting to name a volcano!

Cool chiasmus.

And so it turned out that it was, in fact, the volcanic nature of the Earth that caused its rise in temperature, and eventual downfall of the humam species.

well supervolcanoes don't erupt annually do they

Nah, there are dozens of us. DOZENS!

Are you kidding a BBC Documentary ? This is gonna be a Hollywood Blockbuster starring Nic Cage soon enough

Which implies we only came to develop when hell froze over.

Damn.

So that's where Xenu dumped the aliens...Clever Bastard!

They release less than 1% of the emission that humans do annually.

Any scientist would agree with you. The more you learn, the more you realize we know very little. No scientist walks around thinking they understand the plants!

It will be Transformer 7, where nic cage and friends deciphered the Declaration of Independence and discover earth is actually a giant spaceship - those volcanoes are rocket thrusters.

Optimus Prime gets beat up in slow-mo for an hour. Mark Walberg frowns into the distance for the other hour.

Super underated movie.

My climate change denying father in law is obsessed with volcanoes - they are somehow an excuse for human pollution.

You mistake me. Talking heads and wise men have prophesized and obssessed over the end times for millennia. I would consider it an distinct privilege to witness how this mutherfucker ends

I farted. That should help.

Well...uh...that's something I didn't expect to learn today...

The weirdest part for me is that they've found females with multiple males merged into them..

Like, there's a little bit of macabre morbid romance of casting off all the things that made you an individual organism and fusing with your mate to become literally a part of them...and then she just goes and absorbs some other blokes like it's not a big deal you let your eyes rot off for her.

Women.

I just hope these 91 volcanoes don't erupt in the next tenor so years.

Don't you fucking dare

He created the entire idea of nature documentaries. Everything you've seen since have been adaptions of his vision. The guy is largely responsible for the environmental movement for the last ~50 years. And besides that, he's gone in the field as much as his body will allow. He speaks with an experience and passion that few others will ever understand, although you can hear it in his voice.

It uses the same logic as the Americas being "the west" even though if you travel west from the Americas you get to Asia (which is known as "the east")

May as well use this time to remind Attenborough fans that Blue Planet 2 will be on our TVs sometime soon!

Oh shit, they found hell.

Bruh just wait til you hear about morphemes and shit. Its wild.

ok tell the truth... how easy would it be for me to guess your password

Maybe they are causing some ice melting.

Wait does this mean that theres a fuck load of species in it ? Fuck i hope theres mammoths

Well, think about how there is a western and eastern hemisphere. Both of those intersect with Antarctica. There you go

well, that ice is reaaaaaal heavy, so the volcanoes get too tired holding it up to go off
