Almost 1,000 icebergs counted in N.L. shipping lanes so far this year

This is the 18th most severe season since 1900, says U.S. Coast Guard's International Ice Patrol.

Iceberg Alley off Newfoundland has been an especially dangerous stretch this year with almost 1,000 icebergs counted in North Atlantic shipping lanes since February.

Gabrielle McGrath, commander of the U.S. Coast Guard's International Ice Patrol, said Monday it's already among the top 20 most severe ice seasons on record since 1900.

A final ranking won't be known until later this year as some bergs are still drifting south, she explained.

"There are definitely a lot still in the Gulf of St. Lawrence and near the entrance to the Strait of Belle Isle and then up along the Labrador coast," she said in an interview.

The gigantic slabs of prehistoric ice break off from Greenland glaciers then move south. They drift in whatever direction the currents and winds take them.

The count continues but it's so far the 18th worst ice season on record, McGrath said.

"Considering that number goes back the whole way to 1900, even the 18th most severe is still pretty significant when you're looking at 117 years of data."

In 2014, there were 1,546 icebergs in the shipping lanes, making it the sixth highest count since 1900. There were 1,165 icebergs in 2015.

The International Ice Patrol was formed after an iceberg sank the Titanic in 1912. It works with Canadian partners to track conditions, including using surveillance flights, and update mariners.

McGrath said the patrol has a perfect safety record for those who heed its warnings.

As of Monday, there were about 12 icebergs drifting through the shipping lanes off eastern Newfoundland, after making their way down iceberg alley, the flow of ocean current that brings icebergs from Greenland, down the coast of Labrador andtowards Newfoundland.

McGrath said a series of low-pressure systems last spring drove hundreds of icebergs close to shore along with unusually thick sea ice.

The height of the ice season is typically in late May or June but several bergs along Newfoundland's eastern coast have lit up social media this month.
