450 icebergs disrupt Atlantic shipping


In the North Atlantic shipping lanes where the Titanic struck an iceberg 104 years ago and sank, more than 400 icebergs have been reported in the past week nearly two months ahead of the normal season, forcing merchant ships to slow down and "crawl" or take detour of hundreds of nautical miles.

May significantly delay estimated ETA/ ETA/ ETD and delivery time of ships, disrupting shipping. About 450 icebergs were reported in the North Atlantic shipping lanes over the past week, nearly two months ahead of the normal season, five times the average, CBS reported. An iceberg is defined as a large block of ice with a total area of at least 500 square meters and a thickness of 30 to 50 meters. Not only is there a lot of it this year, but it's coming really fast.

Most of the icebergs that flow into the North Atlantic come from calving ice from Greenland. Mann, director of the Earth Science Center at the University of Pennsylvania, pointed out that the Arctic icebergs are driven southward by unusual counterclockwise (CCW) winds. It could also be that global warming is speeding up the calving of Greenland's icebergs and drifting south.

The U.S. Coast Guard's International Iceberg Patrol said there were about 450 icebergs near Newfoundland's Grand Banks as of Wednesday, up from 37 a week earlier. The number usually doesn't appear until late May or early June, compared with an annual average of 80 at this time of year. Because the area is fairly close to the scene of the Titanic disaster in 1912, ships are wary of the sudden increase in icebergs. Commercial ships sailing to and from the North Atlantic cannot cross the ocean in a straight line and must go around 400 nautical miles longer, the equivalent of an extra day and a half for many large freighters. Some shipping companies are now avoiding parts of the North Atlantic route.

Oceanex, a Canadian company, slowed its ships to 3-4 knots (or 3-4 knots) on their way to SAN Juan, much slower than the normal speed of about 20 knots, adding an extra day to its voyage, the company estimated. Another freighter was forced out of service after hitting an iceberg.
