  • 18 mile crack in glaciermeans the birth of a giant ice-berg is imminent



    In the picture you are looking down into a crack on the Pine Island Glacier, the crack is at least 18 miles long by about 50-60m down to sea level, the ice then continues under the water for about 8 times this distance.

    A massive iceberg larger than Manhattan has broken away from the floating end of a Greenland glacier this week, an event scientists predicted last autumn.

    The giant ice island is 46 square miles (120 square kilometers), and separated from the terminus of the Petermann Glacier, one of Greenland's largest.

      Happy birthday to a new 720 sq km iceberg that calved today off the Pine Island Glacier, the result of the crack reported in the post above.

      Though even at 720 sq km, about eight times the size of Manhattan Island (if that means anything to you, it doesn't to me), it's still a tiddler compared to the 11,000 sq km B-15 that broke from the Ross Ice Shelf in 2001.
