Using high tech monitoring devices, including satellite images, scientists have reconstructed a major climate event that occurred on August 13, 2005. That afternoon the forty-one square mile Ayles Ice Shelf broke free of Canada's Ellesmere Island.
Satellite images and earthquake monitoring devices recorded the event. Nobody lives in the area so it was only digital evidence that existed. Now scientists have visited the newly formed ice island. Its position will be closely watched.
Only five Canadian ice shelves remain connected to land. And measurements show they are 90% smaller than they were a century ago.
