Research: Oil Spills and marine mammals – development and application of a risk-based conceptual framework

Whales eating close to the shore on the North Coast of the Great Bear Rainforest.

Published on 2017.07.24 | by Raincoast | in Marine Mammals & Birds, Scientific Literature

Using BC as a case study, this paper develops a framework for examining risk to oil spills faced by marine mammals. We found that in BC, killer whales (residents and transients), sea otters, and Steller sea lions face the greatest risk of population level consequences, but that many BC marine mammals are at elevated risk…
