Scientists traveling with the Canadian troops found major new fractures during an assessment of the state of giant ice shelves in Canada’s far north.
The team found a network of cracks that stretched for more than 10 miles (16km) on Ward Hunt, the area’s largest shelf.
The fate of the vast ice blocks is seen as a key indicator of climate change.
