NORTH AMERICAN ICE SERVICE PRODUCTS

Recent Enhancements to the North American Ice Service Suite of Products:

  • The Iceberg Limit north of 53°N is now distinguished as an Estimated Iceberg Limit.  This change captures the fact that reconnaissance north of 53°N assesses the overall iceberg population and distribution. South of 53°N, the Iceberg Limit is more closely monitored due to the higher risk of iceberg collision in this region.
  • The Estimated Iceberg Limit now extends east to 28°W, advising mariners of the iceberg danger south of Greenland.
  • This Estimated Iceberg Limit is now identified in a separate paragraph in the NAIS 10 Iceberg Bulletin.
  • This Estimated Iceberg Limit is now represented by a dotted line on the NAIS 65 Iceberg Chart.
  • The NAIS 65 distributed by IIP is now presented in English only. View a French version.
  • In the case of a significant reduction, the cause (predicted deterioration or recent reconnaissance) will be noted both in the NAIS 10 Iceberg Bulletin and on the NAIS 65 Iceberg Chart.
  • In the case of a significant expansion, the cause (predicted drift or recent reconnaissance) will be noted both in the NAIS 10 Iceberg Bulletin and on the NAIS 65 Iceberg Chart.
  • The source of the most recent reconnaissance is now noted on the NAIS 65 Iceberg Chart and NAIS 10 Bulletin.
  • Please view the updated Information Sheets on the Products page for more detail.
  • If you have feedback regarding these enhancements, please complete this survey or contact IIP at 860-271-2626.
     
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.
