ST. JOHN'S, N.L. -- The largest iceberg cluster seen in recent years is drifting south off Labrador through busy transatlantic shipping routes.
The coast guard says there are about 250 icebergs within a 100 kilometre radius of Belle Isle.
But superintendent Peter Veber says the icebergs are unusually far north this year and it's not clear how many will eventually be seen off Newfoundland.
Typically it takes three years or more for an iceberg to travel from Greenland to Newfoundland's coast.
This year, Veber says the most southerly drift is still about 100 kilometres north of Fogo Island.
He says the sea currents, the warmth of the air and water, all help to determine where big ice moves and how fast.
