In 2004 Raincoast began 5 years (7 seasons) of gruelling and expensive boat-based, systematic surveys of BC’s coastal waters to determine the abundance and distribution of marine birds and mammals. This work has been a critical part of our efforts to achieve long-term protection of marine mammals habitats. Over 14,000 km of ocean track line were surveyed between 2004 and 2008, primarily in the waters between Dixon Entrance (Alaska -BC Border) and Johnstone Strait, but also the inside inlets.

The technical findings and modelling from this work can found in the report Predictive Marine Mammal Modeling for Queen Charlotte Basin, British Columbia (PDF).
The findings from our marine surveys were also incorporated into the popular report What’s at Stake: The cost of oil on BC’s priceless coast conveys the ecological implications of oil tankers and oil spills to wildlife on the BC coast. The report stems from the five years of at-sea surveys but places BC’s unique coastline in a broader ecological context.
