NOTE:  The International Ice Patrol is experiencing reduced iceberg reconnaissance.  In response, we are increasing our use of iceberg modeling to assess the iceberg danger and are conservatively establishing the Iceberg Warning Limit to ensure it encompasses potential iceberg hazards for the safety of mariners.  Additionally, the Iceberg Limit is now considered an Estimated Iceberg Limit as indicated on the NAIS-65 graphic and NAIS-10 Bulletin.  Please navigate with caution and report all iceberg sightings to the International Ice Patrol or the nearest Canadian Coast Guard Marine Communications and Traffic Services Station.

The North American Ice Service provides year-round maritime safety information on iceberg and sea ice conditions in the vicinity of the Grand Banks of Newfoundland and the east coast of Labrador, Canada. The purpose of the NAIS Iceberg Bulletin and Chart is to advise mariners of the estimated iceberg extent within the region.

Ships are encouraged to immediately report sightings of icebergs or stationary radar targets that may likely be icebergs to the nearest Canadian Coast Guard MCTS Station or through INMARSAT using Service Code 42, as there is no charge when using this code.
