Marine Bird Surveys
In 2005, Raincoast began 4 years of boat-based, systematic surveys of BC’s coastal waters to determine the at-sea abundance and distribution of marine birds. This work is part of our efforts to achieve long-term protection for maritime animals and their habitats. Over 10,000 km of ocean trackline were surveyed between 2005 and 2008 collecting roughly 18,000 ‘sightings’ (totalling over 100,000 individual birds) in more than 70 species.

Published Analysis
In 2016, we published at-sea distribution and abundance results for BC marine birds, along with a risk assessment for chronic oil spills.

Maps and Reports
The raw sightings data and maps can be viewed in the report Marine Bird Surveys 2005-2008 Raw Sightings Information.

This information was then used in the popular report, What’s at Stake: the Cost of Oil on BC’s Priceless Coast.

Dr. Caroline Fox has also written a popular book At Sea with the Marine Birds of the Raincoast based on her experience as a marine bird biologist surveying the BC coast.

The poster below summarises the sightings and scientific methods behind Raincoast’s seabird data analysis.
