Ellesmere ice shelf could clog seaways

The Ayles ice shelf, the size of 11,000 football fields, broke off Ellesmere Island several months ago, with a suddenness that surprised scientists, and took only an hour to plunge into the ocean.  "It's like a cruise missile has come down and hit the ice shelf," said Professor Warwick Vincent of Laval University.  Now the remains are floating free, the largest iceberg on record, and are so enormous that they may even clog shipping lanes or do damage as the ice collides with man-made structures.  Coming in at 5-15 kilometers and 30-40 meters thick, the ice chunks are likely around 4,500 years old, but the average oil rig will be no match.  [GT]
