- Опубліковано 21 гру 2010
- Antarctica is the iciest place on Earth, but not all of the ice on the continent is the same -- nor is it sitting still. Antarctica has both floating ice and land-based ice. What is the difference between ice sheets, ice shelves and sea ice? How does this ice affect the stratification and circulation of global oceans? How does it affect climate? And why does melting sea ice not raise sea level but melting land-based ice sheets do? For more of Antarctica's Secrets, including teachers' guides, visit www.netnebraska.org/ice.
2 miles deep, anyone else mind blown at that concept?....
One of the more interesting videos I have seen in a long time thank you
Antarctica is the ice wall holding all the water in on a 360 plane
FORCE FIELD IS HOLDING IT TOGETHER
It's a very easy-to-understand video
Fascinating. Love the quest for knowledge in space and below ground.
This is a great video. Timeless, wonderful background, Clear visualizations. Thank you.
Oh God I freaked out a little when he dove into the ground 😲
that part was stupid
Somewhat old, but yet informative video. :)
Antarctica's Ice on the Move has always been on the move. Sailors over 200 years ago reported huge chunks of ice breaking off, causing alarm in European press.
The ice breaks due to tidal forces (up and down) and forward movement into the seas and it huge mass, eventually causes cracking and huge amount of ice breaks off.
Okay, so?
What some people don't understand is that Antarctica is classified as a desert because of the amount or lack of appreciable precipitation. the word desert doesn't always mean hot, dry, and sandy environment.
Amazingly interesting.
9years ago🤔 wow 2020 here we come
COOL!! INTERESTING VIDEO
How do you handle the continuous darkness in southern hemisphere winter?
Wow, Added To My Research Library
Awesome
interesting video
Thanks for your work, Linda. I thought they'd found something ancient down there; hence so many V.I.P.'s suddenly visiting Antarctica. Entirely plausible. Those descriptions of the alien craft suddenly being at speed and then stopping and starting also ties in with flight crew testimony of UFO's from a U.S. aircraft-carrier I saw recently on you-tube, who were also sworn to secrecy.
What if that drilling pipe brakes, what will happen to the water and the marine environment if a disaster happens? Maybe we don't need to be drilling and warming up the water, can somebody please explain me why they are doing that?
What about the freshwater lake that Admiral Bird found?
Antarctica has huge coal Fields.
It was once tropical.
2:00 I thought that I had built a few good snowforts in my youth, but your's makes mine look a bit lame.
They used your money / labor for this Fear porn .
What about diffusion of gases through the ice? I hope they've accounted for that, somehow.
I WILL LIKE TO LIVE THERE .ITS SO PEACE FULL.THE THING IS ITS IMPOSIBLE ..
My computer has been off for sometime as the internet keeps going up every year and the company sends you a bill w/o regards to whether you can pay it or not.
what?
Ice free areas in Antarctica.
That was news to me
As long as our information about our world doesn't end up like the city of "Troy", I think we will be fine in passing down this knowledge.
Just want to know if i can eat the new fallen ice if i wanted to eat...love it😍🤔
You CAN! If you don't mind frostbite in your mouth.
As long as its not yellow!
The Ice is in constant motion, so is the Earth and every thing on it.
...well then. Go on. Git.
Ain't no one here got a bit of use for you.
So's the Universe for that matter. This Universe is an energetic "can do" Universe and not one of your sedentary old Universes.
5:07 Floating body of ice? I just saw new pictures of it setting bedrock yesterday. Yeah the whole continent is a giant floating ice cube. xD
actually its not . what you see at 5:07 is only the edge of the ice sheet aurrounding Antartica,s continent . The continent itself is a gigantic super volcanoe equlaising the size of the super volcanoe that caused the permian extinction or in the science terms ''The Siberian Traps '' once that ice covering it will be melted enoug the earth crust will bounce back and create cracks and weaknesses and then the eruption will start and antartica will finish melting as fast as an ice cube in a glass of water
Nice work you are doing. I hope the giant octopus do not get you.
ChefGiovanni : Nor ‘The Blob’!
I know, that was not funny.... I know.
Time check-2016! October has been breached.
Thank God something legit I'm antartica...
I always had the feeling new zealands and aussies only care about sharks investigation
Ice is always moving. It is never static. It's very fluid. The Ice moves because heavier and thicker ice, the result of seasonal snowfall, presses down and pushes the ice to the ocean. Nothing unusual at all about it.
200,000 years ago it was 2 degrees warmer yes we may have exasperated the warming back up but it will one day stay cold for longer and everything will freeze and one day it will melt
You need to spend about 20 minutes on Wikipedia reading about plate tectonics. It will answer your questions.
All the ice shelfs will break off soon. They break off and add higher levels of water this produces stress on the remaining shelfs because they want to float and rising water will cause them to float thus they too follow the other shelfs by breaking off.
Then God will rotate the earth a bit and it will reverse.
"Antarctica has been covered with ice for millions of years"
Really? How do you know this and where is the proof?
Did you hear that!!! A scientist studying climate, used the term, "Current Warm Period"?
We are going to have SUCH a fantastic record as to how the Anthropecene events occurred...
but whom do we expect to read it...?!
Admiral Bird said land bigger the America with out snow or ice. With enough natural resources to supply the planet for thousands of years
Ppl opp that out as fake....it kills me man....why would he say what he said
Jeff smith, you are a stupid flat earther. You don't matter.
Look what quarantine made me watch
It's nice that the team is trying to find answers, however, nothing stays within known parameters or stays consistent. You guys should know that by now.
Time and nature has shown that to be true all too frequently, so how can anyone define how long a season is with the core samples retrieved?! You can't really, however, you can get a rough estimate. That's because nature fluctuates and is not consistent throughout the year or seasons.
How to get there
Hi
Wouldn't it be nicer if it was a bit warmer during the winter for us all?
Ice is and has always been on the move.
Gosh! I had no clue gravity has always been here....
The snow looks like a cornstarch 😂 Well, I never seen one
So 12 months every day is snow not a sun boy i mean how people make out in their
Due to the fact that the area in question, is guarded & restricted, with over 50 Countries signed up to the Antarctic treaty. I will have to take your word for it won't I!? Can you show water conforming to a Globe, or even being able to bend, in your next inane video?
Nice upper cut
Ice is on the move because snowfall is increasing. As snow deepens and begins to transform into firn, and then to ice, gravity causes the ice to flow (not slide) downhill to the sea.
Although I am always curious for the events these scientist have, I hate to see all those buildings on Antarctica.
It's not all ice though there are also places without snow or ice and hot water lakes.
Mysterious things there in Antarctica
I hope so too, it would be amazing to have another inhabitable continent for humans to live on
Or to destroy
Humans would pollute it faster than the other 6 continents
Luis Mendez You people have destroyed every country south of the border and now you want to destroy America.
At abt 5 mins, he says that they’re sitting on 600 ft of ice. But two other times a figure of 26’ given ...?
The 600 ft figure was on the West Antarctic ice shelf and the 26 ft figure was on the McCurdo Sound Ice Shelf.
2018. 50 years in California with no sea level rise.... What happened??
The penguins drank it all. They must have been very thirsty. It must be the truth as scientists never lie (for government money). LOL.
Nothing but Al Gore and people like him getting rich while giving the EPA much more power to control and tax us more. When Russian Scientists start to worry, well then maybe something will happen but no evidence from them on global warming now called climate change. Would you bet your 401 K they will get the weather forecast right tomorrow but think they really know what will happen in 30 yrs. They do not even know if it will not get colder than warmer. NY was supposed to be underwater by 2012 same thing just more scare tactics. If scientists disagrees with them they cut off funding to him or his place of employment. Now that is Quid Pro Quo for real. They love to keep you scared or worried so you do not have time to relax and actually think.
What presumption, we don’t know what ice ages have come and gone and affected the ice records , we presume it is just an analog history and yet the planets ice ages may skew the record. We need to research with an open mind....
we have warm days and cold days. Many in a season, not years
It looks like a lot of work with no real product at the end . . and then someone said "oil exploration" and it all makes sense .
Paul Fraser probably using our “tax dollars” so the rich remain rich in the end
exactly
Who do you think is doing the deep drilling? You should go there and talk to real climatologists. No hoaxes there.

The Artic is much thicker its been in years. Look up the Australian Geologists/scientists report who have been living there for a decade. Seems like the ice age they were predicting 20 years ago could have merit?
Banjaluka city have most apiece bird in world
The oceans are huge heat and Carbon Dioxide sinks thus it takes a little while for the system to adjust until it reaches its new equilibrium. When I say a "little while" I am speaking in geological terms. In human terms it takes hundreds or even thousands of years for the changes to finish taking place. Even if we don't put any new CO2 into the air, the world will continue to heat up for hundreds of years into the future as it gradually adjusts to the changes we have already made.
Bull
We need more farm land, warmer climate.
Climate change is eternal. This is not new or news.
Mister Berzins But the rate and potential extent of current climate change are exceptional, threatening and at least partly under our control.
It's a bit like tipping over the first domino in a line of millions. The conclusion is fore drawn. The final domino is going to fall but it is going to take a while for all the links in the chain of causality to play themselves out and reach the finish line. That is what is truly disturbing about the amount of CO2 we have already pumped into the air. We have barely even begun to see the repercussions for the dominoes we have already tipped over and yet we keep on knocking down more and more.
Melting Sky too many mushrooms, my man.
@@davidgreen5099 lol
Melting Sky I agree. Don’t forget those GMO’s that were designed to “end world starvation”. Our controllers always present their new “ideas” as humanitarian but after 60 years on this planet, I know them all to be diabolical!
The ice would last much longer if the ice breakers weren't up there breaking it up daily.
Good joke.
Up on Antarctica. The famous land-going ice breakers weren't up there breaking it up daily.
If antarctica becomes green, would our descendants have records of an icy antarctica or will it be forgotten? We should leave records, and remember that if antarctica melts, the sea level will rise 200ft, so will they remember the maps of today or will that be forgotten, too?
Worry more about global cooling than warming, and for God’s sake stop drinking the KoolAid
HariPuttar1 don’t be stupid
Yup, it's been on the move for more than 10,000 years so whats new?
searching for oil
Antarctica melts ocean levels rise. WHY does that happen? Must be magic. Oh well lets look at the penguins arent they cute?
Yeah but as ice melts on land the pressure on the earth reduces causing rebound and the land rises.
ice has not been there for millions of years
Woah holy sheet 10 years ago....
See me in another 10 years anyways :D
This documentary was made in 2010 , It is now 2016 and the earths oceans have risen barely one millimeter , if that. But according to the melting polar cap theory cities should be under water. It has not happened and never will.
+Philip Hunter Have you ever heard of the Marshall Islands and Kiribati? www.theguardian.com/environment/2015/mar/09/losing-paradise-the-people-displaced-by-atomic-bombs-and-now-climate-change
Also 6 years is not a Century!
Record-breaking rain and raging flood waters have been decimating cities and towns all across the world - where is this record humidity coming from?
Record-breaking humidity comes from record-breaking evaporation
The oceans are too warm which is causing the sea water to evaporates at record rates. This is why sea levels are relatively stable - because the sea water is evaporating and inundating cities and towns all across the world.
MASSIVE volumes of glacial melt are flowing into the oceans from Antarctica, Greenland, Canada, Norway, Russia, Alaska, the Andes, etc., meanwhile equatorial ocean waters are abnormally warm and rapidly evaporating -
wind currents carry the evaporated sea water to low pressure areas where record-breaking rainfall and raging flood waters decimate the cities, towns and villages - this is happening all across the world.
Monitor the floods across the world and you may begin to realize why sea levels appear to be relatively stable while cities are being washed out to sea - every day.
Yeah right, even Exxon Mobil internally are worrying about climate change
r pray . atomic bomb detonation causes the subsidence of these atolls and consequently flooding, not melting polar caps.
Philip Hunter see I can be as constructive as you! If you have nowt to say that's nice don't bother!
is antartica the south pole
Yep they are volcanoes under there
There is not one iota of knowledge gained that will change a thing.
Well not in your head anyway.
there is no Antarctica, what you are seeing is the wall of ice around the plane
are they really swimming in antarctica :') ?
2006, major drought, icebers...."travelling further then usual...'CLIMATE EMERGENCY"
1908, heat waves etc, 1910 ice movement warnings...1912...Titanic sinks......."THE GERMANS...maybee"
I always said that drilling through ice creates dysfunction in stability of ice sheets.....
of course it does . Only the assholes who drilled those holes think that their holes wont impact anything .
the planet turns over time the poles do not stay in the same place ...so yes the ice is moving...
0:40 - "surprisingly this ice is on the move". Pure ingnorance. The ice is building up (snow) movig outwards all the time.
Probably drilling for everything you can think of and not just rocks.
funny they can drill, yet, no one else can go down there. whatever
Who is funding this project?
HEY, LOOK!!!! ACTUAL STEM!!!!
Antarctica covers 14.2 E6 km^2 (NBS equivalents: 20 * Texas, 2,768 * Delaware or 163,218 * Manhattan) with an average ice cap thickness of 1.9 km for a volume of 2.698 E7 km^3. (L*W*H math)
Ice has a density of 9.2 E11 kg/km^3. (engineering)
The Antarctic ice cap (NOT sea ice!) contains 2.482 E19 kg of ice, 2.482 E16 tonne, 24.82 E6 Gt. (science)
Between 2002 and 2012 the Antarctic ice cap “lost” about 1,200 Gt or a decrease of 0.0048%, 48 ppm, per decade. (technology)
At that rate the ice cap will be all gone in 206,850 years. (more math)
I don’t plan on waiting around.
You?
Every year the SEA ICE swings from around 3E6 km^2 during summer to 14E6 km^2 (doubling in size) during winter. (technology)
Thwaites glacier is 192,000 km^2 or about 1.3% of the ice cap.
Yawn!!!!!
Anything to extract some oil, am I right? Even excuses why they have to dig deeper lol.
You know why its on the move is because so much snow
why does melting sea ice not raise sea level but melting land-based ice sheets do? do they? and by how much? because the earth is NOT "solid" and we all know the land based ice sheets have in fact "displaced mantel martial".....in other words the land based ice is "floating" it just happens to be floating on the mantel and not the ocean. if it were removed the mantel that is displaced would flood back in and it would need to come from somewhere and that some where is most probably the bottoms of the ocean trenches where the crust is already under huge amounts of pressure from the depth of the ocean above.....it seems to me that the most probable out come would be a "deepening" of the seduction zones with little to no net rise in "sea level" at all (beyond historical norms that is)
ok so let me get this right, just befor 220 in the video the guy says and shows with his hand jestures approximatley 3foot is a years worth of snow fall.?
ok so your telling me they are checking from 100000 years ago that means they would have to drill 300000 feet, i dont think so
+cofferdamn It compresses as it sits longer, so no, thats not what they're telling you.
even whith compression it would be a deep hole, i just dont buy it
cofferdamn
What? I don't think you get it at all. Just like the earth/soil itself settles and compacts over years and years.
+cofferdamn That would be assuming the snow doesn't compress into Ice. The main difference between seasonal snow and glaciation is compression. The further down they go into the ice the thinner each layer becomes due to the massive weight above.
compression
Absolutely stunning, dramatic sea level rises destroying many islands and causing significant loss of costal areas, especially in the north due to the princibles of gravity, sounds brilliant. Not to mention severe adverse weather changes on a global scale is another benefit. How can you not love our consumerism economy and the side effects it brings.
I'm not sure if you're taking the piss but all that information is incorrect. If the ice just on antartica would melt it's estimated a 65+ meter sea level rise would occur. It has been doccumented since the late 1800's until now that the sea level has risen 8 inches. So, just from that incrediby small percentage of ice melting has already risen the sea level 2/3 of a foot.
Think about what you said "Antartica ice is only 1/100 of the mass of the percentage of sea, 1 foot rise" That information would suggest that the average depth of the ocean would be 100feet, so when antartica would melt it would bring sea level to 101feet. The actual average depth of the ocean is 17,000 feet. What you have been reading or told is complete nonsense.
produce giant solar panel for giant ice maker people of the world it can do this if they unite to do that start now before toolate..
that is what glacier's do
It's not in ice it's the atomsphere
Antarctica has the largest desert in the world.
No GW hysteria...nice. So it is the yearly shelf ice they show melting...with the OMG were melting...bs.
first thing I thought when I heard "yearly ice melt".
the ring by the sun is chemtrail for geoengineering
and rest is like bla bla bla
In these ice cores, is there any indications of man, in his insanity, poisoning the atmosphere, the very air we breathe, and the water we drink, to such a degree as we see today?
Greg Fitton lol are you an idiot?😆 day yes
Save the Earth...turn off your computer...any volunteers ?
Stopping breathing people the birds and fish need air!
My computer draws 150 Watts, with the GTX 1060 rolling full tilt. Now, let's talk about your SUV.
