A Manhattan-sized chunk of ice is drifting towards the coast of Canada - providing a stunning sight for tourists, but posing a potentially serious threat to shipping.
The 20-square-mile chunk of ice broke off a glacier in Greenland nearly a year ago and is headed towards the Newfoundland coast.
It was formed when a 97-square-mile chunk of ice broke off the Petermann Glacier on August 5, 2010, possibly due to warming of the Atlantic Ocean.
The ice island - at roughly 6.2 miles long and 3.1 miles wide the largest single chunk remaining from the massive parent chunk - has been winding its way through Arctic waters ever since.
In the past few days, it has been moving south at a rate of 5 to 6 miles per hour.
