Dear Member,

Further to CL11279, the second edition of the Mariners Guide to Whales in the Northwest Atlantic is available in both print and in digital format, at no cost to members. Our goal is to provide a copy of this guide to each vessel that visits the Atlantic coast of Canada.

Created as a collaboration between Shipping Federation of Canada, WWF-Canada, and the Marine Mammal Observation Network, this guide is designed to support the work of mariners by providing up-to-date maps of areas that whales are known to frequent in the vital shipping trade corridors of the Atlantic Region and the St. Lawrence, and encourage greater vigilance in those areas. The maps in this guide include observation data gathered by some of our members.

The guide also includes identification keys for whales, information on measures that can be implemented to help protect them, and guidance on what to do in the event an entanled or otherwise distressed whale is observed.  Awareness remains a key tool for ensuring the safe coexistence of ships and whales, and mariners play an essential role in this respect by keeping their eyes on the water.

Ordering copies

Members who wish to receive hard copies of the guide (available at no cost), please contact the undersigned with the number of copies desired, and the address and contact person to whom they should be delivered (delivery in Canada is preferable). Each copy will be accompanied by a cover letter introducing the guide and its intended use for those on board the vessel.

An electronic version of the guide is available online in English and in French by clicking on the respective images below.
