Dear Member,

Further to CL11279, the second edition of the Mariners Guide to Whales in the Northwest Atlantic is available to members free of charge in both print and in digital format. Our goal is to have a copy of this guide to each vessel that visits the Atlantic coast of Canada. Thank you to our many members who have done so already, we hope it is being used and enjoyed. We are aware that when this guide was first released in 2021, agents were not boarding vessels and opportunity to distribute these books was limited, and so are providing this additional opportunity.

Created as a collaboration between Shipping Federation of Canada, WWF-Canada, and the Marine Mammal Observation Network, this guide provides up-to-date maps, such as the one below, of areas that whales are known to frequent in the Atlantic Region and the St. Lawrence, and encourage greater vigilance in those areas. The maps include observation data gathered by some of our members.

The guide also includes graphics and identification keys for local whales, information on measures that can be implemented to help protect them, and guidance on who to contact in the event you observe an entangled or otherwise distressed whale. 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. The Federation will ship you copies, and each 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.
