1 00:00:06,820 --> 00:00:12,180 This year researchers witnessed for the first time evidence of an ice mass separation triggered by a tsunami. 2 00:00:12,200 --> 00:00:15,980 Until this discovery scientists could only speculate this was possible. 3 00:00:16,000 --> 00:00:21,980 The large mass of ice separated from the coast of Antarctica on a part of the continent called the Sulzberger Ice Shelf. 4 00:00:22,000 --> 00:00:29,980 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. 5 00:00:30,000 --> 00:00:39,980 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. 6 00:00:40,000 --> 00:00:45,980 Evidence of the separation was first observed in images captured by NASA's Aqua and Terra satellites. 7 00:00:46,000 --> 00:00:53,580 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. 8 00:00:53,600 --> 00:01:03,980 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.
