NASA | Tohoku Tsunami Creates Antarctic Icebergs


This year researchers witnessed for the first time evidence of an ice mass separation triggered by a tsunami. Until this discovery scientists could only speculate this was possible. The large mass of ice separated from the coast of Antarctica on a part of the continent called the Sulzberger Ice Shelf. The Tohoku earthquake and tsunami that struck Japan in March of this year also generated sea swell that propagated throughout the Pacific basin, as seen in this model. Within 18 hours the first series of waves bombarded the ice shelf, located 8,000 miles away, ultimately resulting in a mass of ice 50 square miles in size being shed from the continent. Evidence of the separation was first observed in images captured by NASA’s Aqua and Terra satellites. Looking through a hole in the clouds, researches spotted a single iceberg roughly the size of Manhattan, drifting off the coast of the ice shelf. Using radar imagery from a European Space Agency satellite, scientists discovered not only one, but two large icebergs, along with several smaller pieces of ice that had separated from the continent. An aerial photo from the USGS archive dating back to 1965 shows the area of the ice shelf that separated had been intact for more than 46 years. The separation occured at a time of year when sea ice around the continent is at a minumum; suggesting sea ice may play a critical role in ice shelf stability.

  1. Excellent video. See my channel electric motor new design.It is very original model of electric motor (it has no accelerating coil, special phase-shifting devices and condensers).

  2. NASA LIES TO THE HUMAN RACE. TELL THE TRUTH ABOUT ALIENS AND UFOs MOTHERFUCKERS.

  3. @chilango99mex Come on dude, don't ashamed Mexico with your stupid comments, now all of us are going to look like a bunch of ignorant people. People, we al mexicans are not like this guy, believe me.

  4. @dumdeedum27 actually when ice melts the water level wouldnt rise it would stay exactly the same you can test it with a glass of ice water.

  5. @smokeymcpottz but that's still mad fresh water dumping into the ocean cramping its style

    God doesn't exist, dude.

    Must of the people in your country believes in God which doesn't exist. Basicly as stupid as muslims that takes alah so serious. In the end, its all about believeing.. nothing else.

  7. How many times are you going to repost this old video and give it a new title every time???? pleases spare us

  8. @smokeymcpottz I hate to say this but your wrong. If I filled a glass up to the brim with water and then place an ice cube in the glass it will spill over correct? The ice cubes sink to the bottom displacing the water. If you where to submerge all the glacial ice that is above the water level would this not displace the water in the oceans?

  9. @Gliese581f i mean no disrespect but im not wrong he was talking about icebergs floating in water if they were to melt there would be absolutely no rise in sea level. are you referring to ice thats formed on land because yes that would increase sea level slightly. and you have me confused with the last part because ice does not sink due to it being less dense than water.

  10. @Gliese581f yes if you filled a glass to the brim with water then add ice it would overflow, that is the same as just adding water to an already full glass… if you fill a glass to the brim (with ice already in the glass), just like icebergs are already in the ocean, and let it melt your glass would not overflow no matter how much of the ice is above the water level

  11. @smokeymcpottz My bad, I misread your statement. I thought your where talking about the ice that is currently on land not icebergs. Have a good one.

    Give me any serious scientific study that proves god existence. There is none.

    Science is above all.
