  • Ice Patrol uses radar technology to track the path of icebergs in the North Atlantic


  • Ice Patrol was set up as a direct consequence of the Titanic disaster.


  • Icebergs in the Western North Atlantic that enter shipping lanes come primarily from the West Coast of Greenland.


  • The freezing current that carries the icebergs is called the Labrador.


  • The Labrador Current cuts into the warmer Gulf Stream.


  • In 1912, over 1000 icebergs entered the North Atlantic shipping lanes.


  • On average, 500 icebergs enter the North Atlantic shipping lanes.


  • The iceberg that wounded the Titanic came from the Greenland Glaciers and was carried by the freezing Labrador Current.


  • 9/10ths of an iceberg is under water.


  • Before remote technology, forecasters relied on ships that travelled the world, and took the air and water temperatures every four hours. Meteorological offices of the ships’ countries used these readings to build synoptic charts of the weather.


  • A NOAA center in Asheville, North Carolina stores all weather data sent by thousands of ships that crisscrossed the oceans of the globe.


  • Titanic most likely sank in the Labrador Current.


  • The German Climate Data Center in Hamburg stores about 37,000 journals from sailing ships and steamers beginning in 1829.


  • The Labrador Current brought freezing water underneath the air warmed by the Gulf Stream.


  • Cold water mirages are commonly seen in the right conditions.
